[0053] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0054] It should be pointed out that the embodiments of the present invention and the features in the embodiments may be combined with each other if there is no conflict.

[0055] When a program or system is started or running, it can read and execute each configuration item in the configuration file to configure the value corresponding to the name of the configuration item, so that the corresponding configuration state is displayed during the program or system running stage. By configuring the program or system through the configuration file, the program or system operation can be separated from the configuration process. When running the program or system in different scenarios, only the configuration items in the configuration file can be modified without re-adjusting the program or system code for compilation, thereby saving program or system development time and improving development efficiency. The configuration file can include multiple configuration items, each of which can include the name and corresponding value of the configuration item, and the values ​​in the configuration items are static and will not change with changes in the program or system operating environment to be configured.

[0056] However, the values ​​of configuration items in existing configuration files are static, which are determined when the program or system is started, and will not be adjusted with the state of the program or system during operation. It is not possible to dynamically start / close certain configuration items according to the current service environment, and it is not possible to dynamically adjust the values ​​of configuration items according to the current service environment, which will cause the state of program or system operation to be relatively simple and inflexible. For example, a configuration item is usually "a:b" or "a=b", which means that the name of the configuration item is a and the value is b, that is, the values ​​in the configuration items are fixed and unchanged.

[0057] In some scenarios, it is sometimes necessary to determine whether to execute the configuration item based on the actual situation of the system or program, and the value of the configuration item needs to be automatically adjusted as the system or program runs. That is, in actual production scenarios, some systems or programs need to rely on configuration files that can dynamically adjust configuration values ​​to execute configuration. For example, in e-commerce systems, it is a common operation to increase the exposure of high-quality items by adjusting the position of the items, and the position of the items can be adjusted based on the values ​​of its different features or the results of each feature operation. Therefore, when adjusting the position of the items, it is necessary to dynamically calculate the real-time data of the features included in the configuration items. Therefore, when configuring, some configuration items in the configuration file need to be calculated based on the actual feature values, and then decide whether to execute based on the calculation results; some configurations need to be executed but the configuration values ​​need to be determined based on specific feature data.

[0058] Therefore, an embodiment of the present invention provides a dynamic configuration method for dynamically configuring configuration items in a configuration file of a system or program. In the embodiment of the present invention, the system dynamic configuration is used for explanation.

[0059] The embodiment of the present invention provides a method for dynamic configuration, which can be executed by a terminal device, such as Figure 1 As shown, the method includes the following steps.

[0060] S101: Acquire a configuration file including at least one target configuration item.

[0061] Among them, the target configuration item includes a configuration item expression of the target configuration parameter and a configuration value expression of the target configuration parameter. The target configuration item is the configuration item for parameter configuration included in the configuration file. Each target configuration item corresponds to a target configuration parameter. The target configuration parameter represents the parameter corresponding to the configuration value determined by the target configuration item, that is, the configuration value determined by the target configuration item is assigned to the target configuration parameter. The target configuration item may include a configuration item expression and a configuration value expression. The configuration item expression is used to determine the scope of use of the target configuration item, that is, whether the target configuration item is used to execute the configuration in this system operation, and the configuration value expression is used to determine the value of the target configuration parameter for this operation. In the computer field, the configuration process is usually performed during system initialization or operation. The process of executing the configuration is usually to first obtain the configuration file, and then execute each configuration item in the configuration file in sequence to complete the configuration.

[0062] In an embodiment of the present invention, a configuration file may include at least one target configuration item. A target configuration item in the configuration file is represented by a key-value pair, wherein the key is used to represent the configuration item expression, and the value is used to represent the configuration value expression. The configuration item expression and the configuration value expression included in the target configuration item may include one or more combinations of variables, constants, operation logic composed of operators (including arithmetic operators, logical operators, bitwise operators, etc.), etc.

[0063] Specifically, the structure of the target configuration item can be as follows Figure 2 As shown. Both key and Value support expression parsing. Figure 2 In the example, the expression in key is a configuration item expression, and the expression in value is a configuration value expression. In the embodiment of the present invention, since the expression in key is used to determine whether the target configuration item of this operation is used to execute the configuration, the return result after the expression in key is calculated can be set to true or false. When the configuration item expression is true, the return result is true, indicating that the target configuration item can execute the configuration and the configuration item is effective; when the configuration item expression is false, the return result is false, indicating that the target configuration item does not need to be executed and the configuration item is not effective, so the expression of Key returns a Boolean result. For example, the expression of key can be "x||y", "true", "x+y<1", "(a&&b)||(4+x>100)", etc., where x, y, a, and b can all be Boolean variables, and the values ​​of these variables can be obtained during the execution of the configuration file, and then the return result, such as true or false, is determined according to the value of the variable, which is a Boolean result. In the embodiment of the present invention, the expression in Value is the expression of the configuration value, that is, the configuration value corresponding to the target configuration parameter can be determined by calculating the expression in Value. Configuration values ​​are usually numerical values, so the result returned by the Value expression can be set as a floating-point type in the embodiment of the present invention. During the configuration process, a numerical value is obtained by parsing and calculating the Value expression, and the numerical value is loaded into the program running in the system to assign the corresponding target configuration parameters. For example, the expression in value can be: "1+2", "m+n", "m*2+n+1", etc., where m and n are both numerical variables. The value of the variable can be obtained during the execution of the program, and the configuration value can be calculated.

[0064] S102: For each target configuration item, determine whether the target configuration item is used to execute configuration according to the configuration item expression; if so, determine the configuration value corresponding to the target configuration parameter according to the configuration value expression, and configure the target configuration parameter according to the configuration value; if not, ignore the target configuration item.

[0065] Among them, when executing the configuration file, each target configuration item in the configuration file needs to be processed. Since the target configuration item implements dynamic configuration, that is, whether the target configuration item needs to be configured and the configuration value in the target configuration item can be determined according to the specific scenario when the system is running, so in this step, for each target configuration item, you can first judge whether the target configuration item is used for execution configuration according to the expression of the target configuration parameter. The target configuration item is used for execution configuration, which means that the target configuration item needs to be configured during the current system operation. At this time, the configuration value corresponding to the target configuration parameter can be determined according to the configuration value expression, and the determined configuration value is configured to the target configuration parameter; the target configuration item is not used for execution configuration, which means that the target configuration item does not need to be configured during the current system operation, and the target configuration item can be ignored.

[0066] like Figure 2 As shown, in the embodiment of the present invention, the configuration item expression may include variables, constants, operation logic, etc. Specifically, the configuration item expression may include a first target variable and a target value, and judging whether the target configuration item is used to execute the configuration according to the configuration item expression may be specifically performed as follows: obtaining the current value of at least one first target variable; judging whether the target configuration item is used to execute the configuration according to the current value and the target value.

[0067] The first target variable is usually a variable with physical meaning. The target value indicates the condition when the target configuration item is used for configuration. It can be one or more specific values ​​or a value within a range. For example, the configuration item expression can be "a=x||y", where a represents the color of an item, x represents red, and y represents blue. The first target variable is a, and x and y represent the target values.

[0068] When the system is configured, the current value of the first target variable can be obtained, and then the target configuration item is judged whether it is used to execute the configuration according to the current value and the target value, so as to determine whether the target configuration item is used for configuration according to the specific operation scenario of the system, that is, to dynamically determine whether the target configuration item is used for execution, thereby realizing dynamic configuration. Specifically, the judgment process can be performed as follows: if the current value is within the range of the target value, it is determined that the target configuration item is used to execute the configuration; if the current value is not within the range of the target value, it is determined that the target configuration item is not used to execute the configuration.

[0069] The target value can be a specific value or a value range. When the target value is a specific value, the current value in the range of the target value indicates that the current value is a specific value included in the target value. At this time, it can be determined that the target configuration item is used to perform the configuration. The current value is not in the range of the target value, which indicates that the current value is not a specific value included in the target value. At this time, it can be determined that the target configuration item is not used to perform the configuration. For example, the configuration item expression can be "a = x", where a represents the color of an item, x represents red, the first target variable is a, and x represents the target value. At this time, if the current value of a is red, it is determined that the target configuration item is used to perform the configuration. If the current value of a is not red, it is determined that the target configuration item is not used to perform the configuration. When the target value is a value range, the current value in the range of the target value indicates that the current value belongs to the range determined by the target value. At this time, it can be determined that the target configuration item is used to perform the configuration. The current value is not in the range of the target value, which indicates that the current value does not belong to the range determined by the target value. At this time, it can be determined that the target configuration item is not used to perform the configuration. For example, the configuration item expression may be "a=x||y", where a represents the color of an item, x represents red, and y represents blue. The first target variable is a, and x||y represents the target value, and the target value range is x or y. At this time, if the current value of a is red or blue, it is determined that the target configuration item is used to execute the configuration. If the current value of a is neither red nor blue, it is determined that the target configuration item is not used to execute the configuration.

[0070] When the configuration item expression includes multiple first target variables, or includes constants in addition to the first target variable, logical operations are usually performed between the multiple first target variables or the first target variable and the constant, so the configuration item expression may also include the operation logic corresponding to the first target variable. At this time, the process of judging whether the target configuration item is used to execute the configuration according to the current value and the target value can be specifically performed as follows: according to the current value and the operation logic corresponding to the first target variable, the operation result corresponding to the first target variable is calculated; and according to the operation result and the target value, whether the target configuration item is used to execute the configuration.

[0071] That is to say, after obtaining the current value of the first target variable, a logical operation must be performed first to obtain the operation result corresponding to the first target variable, and then the operation result corresponding to the first target variable is compared with the target value judgment target configuration item to determine whether the target configuration item is used to execute the configuration. For example, the configuration item expression can be "e+f<1", where e represents the number of items and f represents the number of comments on an item. The first target variables are e and f, and the operation logic corresponding to the first target variable is +, and a value less than 1 represents the target value. After obtaining the current values ​​of e and f at runtime, an addition operation is performed first, and then compared with the target value to determine whether the target configuration item is used to execute the configuration.

[0072] It should be noted that the process of judging whether the target configuration item is used to execute the configuration according to the operation result and the target value can be performed as follows: if the operation result is within the range of the target value, the target configuration item is determined to be used to execute the configuration; if the operation result is not within the range of the target value, the target configuration item is determined not to be used to execute the configuration. In an embodiment of the present invention, the configuration item expression can also be a constant, and this constant has a fixed meaning. For example, if the configuration item expression return result is set to true and false, the configuration item expression can be true to indicate that the target configuration item is fixedly used to execute the configuration, or the configuration item expression can be false to indicate that the target configuration item is fixedly not used to execute the configuration. At the same time, the target value in the configuration item expression can also include variables. When determining the target value of the configuration item expression, the current value of the variable can be determined first, and then the target value can be determined.

[0073] In an embodiment of the present invention, the configuration value expression may include one or more items such as variables, constants, and operators. Specifically, when the configuration value expression may include only constants, it indicates that the configuration value of the target configuration item is a fixed value, that is, the constant included in the configuration value expression. The configuration value expression may also include only one variable, that is, a second target variable, in which case the current value of the second target variable may be obtained, and the current value of the second target variable obtained is the configuration value corresponding to the target configuration parameter. The configuration value expression may also include the operation logic corresponding to the second target variable, in which case the method for determining the configuration value corresponding to the target configuration parameter may be performed as follows: obtaining the current value of the second target variable; and calculating the configuration value corresponding to the target configuration parameter according to the current value and the operation logic corresponding to the second target variable. That is, when the configuration value expression includes the operation logic corresponding to the second target variable, it indicates that the reverse logical operation is required, so after obtaining the current value of the second target variable, it is necessary to calculate according to the operation logic corresponding to the second target variable, so as to obtain the configuration value corresponding to the target configuration parameter. For example, the configuration item expression can be "m+n-2", where m represents the ranking of the item, and n represents the sales quantity of the item. Then m and n are the second target variables, 2 is a constant, and + and - are the operation logic.

[0074] It should be noted that when the configuration item expression includes operation logic, it can be the operation logic between multiple second target variables, or it can be the operation logic between the second target variable and a constant.

[0075] In an embodiment of the present invention, the configuration file includes at least one target configuration item, and the target configuration item includes a configuration item expression of a target configuration parameter and a configuration value expression corresponding to the target configuration parameter. Therefore, for the target configuration item, the embodiment of the present invention can determine whether the target configuration item is configured by the user according to the configuration item expression, and after determining that the target configuration item is used for configuration, determine the configuration value corresponding to the target configuration parameter through the configuration value expression, thereby realizing dynamic configuration of each target configuration item in the configuration file. In this way, the configuration file in the embodiment of the present invention can realize dynamic configuration of the target configuration item, meet the dynamic configuration requirements of whether the configuration item in the same system or program is configured, or the configuration value according to specific conditions, and solve the problem that the configuration items and corresponding values ​​in the configuration file are static, so the configuration items in the configuration file cannot be changed, resulting in the configuration failing to meet the dynamic configuration requirements.

[0076] It should be noted that the embodiments of the present invention can be used in various scenarios that require configuration.

[0077] Specifically, it can be used in the configuration of system initialization, and whether each target configuration item is used for configuration can be determined according to the system's own situation, as well as the specific configuration value. For example, when the system is initialized, the number of threads can be configured based on the number of CPUs included in the system operation device. At this time, the number of threads can be configured to 3 when the number of CPUs included in the system operation device is 2. The target configuration parameter is the number of threads, and the configuration item expression of the target configuration parameter corresponding to the target configuration item includes a first target variable and a target value, wherein the first target variable is the number of CPUs included in the system operation device, and the target value is 2. The configuration value expression of the target configuration parameter corresponding to the target configuration item is a constant 3. That is to say, for this target configuration item, when the system is initialized and configured, the number of CPUs included in the system operation device will be obtained first. If the number of CPUs included in the system operation device is 2, the configuration will be executed, that is, 3 will be assigned to the target configuration parameter (number of threads); if the number of CPUs included in the system operation device is not 2, the target configuration item will be ignored.

[0078] Specifically, it can be used to configure some parameters during the operation of the system. For example, in the field of e-commerce, the ranking position of items with good sales can be adjusted according to real-time data. For example, if the sales volume reaches 100, the ranking position of the items will be adjusted. The number of digits to be adjusted can be adjusted according to the characteristic data of the items, that is, the ranking position of the items is configured. At this time, the target configuration parameter is the number of digits to be added to the ranking position. The configuration item expression in the target configuration item corresponding to the target configuration parameter can be w>100, that is, the first target variable w is the sales volume of the item, and the target value is 100. The configuration value expression can be a specific value or an expression calculated based on the characteristics of the item.

[0079] Combine the following Figure 1 The embodiment shown in the figure specifically describes the method of dynamic configuration. Figure 3 As shown, the method includes the following steps.

[0080] S301: Acquire a configuration file including at least one target configuration item.

[0081] Among them, the embodiment of the present invention can be used for system initialization configuration and can also be used in the system operation process. The configuration file usually includes multiple target configuration items, and each target configuration item corresponds to a target configuration parameter that is preset. The target configuration item may include a configuration item expression and a configuration value expression. Both the configuration item expression and the configuration value expression may include constants, variables, operators, etc. The target configuration items in the configuration file are usually arranged in a certain order, or the target configuration items are arranged in this step, and the sorting rules are not limited.

[0082] S302: Determine the first target configuration item in the configuration file as the current configuration item.

[0083] After obtaining the configuration file, each target configuration item in the configuration file can be processed in turn. The current configuration item is the target configuration item currently being processed. In this step, the first target configuration item in the configuration file is determined as the current configuration item, indicating that the first target configuration item in the configuration file is processed.

[0084] S303: Parse the configuration item expression of the current configuration item and determine the current result of the configuration item expression.

[0085] Among them, since the configuration item expression in each target configuration item is used to determine whether the target configuration item is used to execute the configuration, the configuration item expression of the current configuration item is parsed in this step. After parsing, the variables, constants and operators included in the configuration item expression can be determined, that is, the specific content of the configuration item expression, and then the current result of the configuration item expression is determined. If the configuration item expression includes a variable, that is, the first target variable, it is necessary to obtain the current value of the variable, and then determine the current result of the configuration item expression in combination with the current value of the variable.

[0086] In the embodiment of the present invention, the return result of the configuration item expression is set to true or false. When the variables, constants, and operators included in the configuration item expression are determined, and the current values ​​of the variables are obtained, the configuration item expression is calculated to be true, and the return result is true, that is, the current result is true; when the variables, constants, and operators included in the configuration item expression are determined, and the current values ​​of the variables are obtained, and the configuration item expression is calculated to be false, the return result is true, that is, the current result is false.

[0087] S304: Determine whether the current configuration item is used to execute the configuration according to the current result of the configuration item expression. If so, execute step S305; if not, execute step 307.

[0088] In the embodiment of the present invention, the return result of the configuration item expression is set to true or false, so the current result of the configuration item expression is true or false. If the current result is true, it means that the current configuration item is used to execute the configuration, and step S305 can be executed; if the current result is false, it means that the current configuration item is not used to execute the configuration, and the current configuration item can be ignored, and then step S307 is executed to process the target configuration items in the configuration file in sequence.

[0089] S305: Parse the configuration value expression of the current configuration item, and determine the configuration value corresponding to the target configuration parameter.

[0090] Among them, in this step, the configuration value expression of the current configuration item is parsed, and after parsing, the variables, constants and operators included in the configuration value expression, that is, the specific content of the configuration item expression, can be determined, and then the calculation result of the configuration item expression can be determined, that is, the configuration value corresponding to the target configuration parameter. If the configuration value expression includes a variable, that is, the second target variable, it is necessary to obtain the current value of the variable, and then determine the result of the configuration value expression in combination with the current value of the variable.

[0091] S306: assigning the configuration value to the target configuration parameter corresponding to the current configuration item.

[0092] After determining the configuration value corresponding to the target configuration parameter, the configuration value can be assigned to the target configuration parameter to achieve normal operation of the target configuration parameter in the system after the assignment.
