[0022] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0023] In such Figure 1In the application environment shown, the client can run in the first device 101, the second device 102, and the third device 103. The first device 101, the second device 102, and the third device 103 can be, but are not limited to, various personal computers, laptops, smart phones, vehicle terminals, tablet computers, and portable wearable devices; the server 104 can be implemented as an independent server or a server cluster composed of multiple servers. The client and the server 104 can be connected to the network communication through a wired or wireless network, specifically through the Internet, a local area network, Bluetooth, or ZigBee protocol and other communication methods.

[0024] In one embodiment, Figure 2 As shown, a method for generating an application ID code is provided, which is applied to Figure 1 The application environment in the example is used to illustrate the following steps:

[0025] S202, receiving an encoding instruction from the client.

[0026] The encoding instruction can be a string, order number or fixed code, which is used to identify, represent and distinguish information of different businesses, and can provide information about properties, characteristics or other important information. Before receiving the encoding instruction from the client, it is necessary to pre-configure the component dependencies and other configuration file resources. For example, the corresponding component can be configured through Maven or Gradle.

[0027] S204, determining a corresponding coding category according to the coding instruction; the coding category includes first-category coding and second-category coding.

[0028] Among them, the encoding instruction includes the prefix character carried by the client, and the corresponding encoding category is determined according to the prefix character. It should be noted that in this embodiment, the application ID code is a unique identifier in a distributed system. In order to improve uniqueness and traceability, it is usually composed of multiple parts. The encoding category refers to the application ID code classified according to its composition, purpose and characteristics in different application scenarios. For example, Class I codes and Class II codes represent different components. Accordingly, different components can be applied to scenarios such as version updates, log records, and business processing. It should be understood that the Class I and Class II codes here can also be generated in combination with other algorithms or specific application scenarios, such as user ID, geographic location and other information, which are not limited here.

[0029] S206, obtain corresponding coding identification information according to the coding category; the coding identification information includes first-class information and second-class information; the first-class information corresponds to the first-class coding, including the timestamp of the current system time, server IP information, machine code, current application process number and random number; the second-class information corresponds to the second-class coding, including the timestamp, server IP information and self-incrementing serial number.

[0030] Among them, the coding identification information refers to the standard used to uniquely identify information to ensure that the application code has a unique identity in the system. Accordingly, the coding identification information corresponds to the coding identification category, and the determination standard of the coding identification information is set according to the coding representation category. It should be understood that the first and second category information here can also be set in combination with algorithms or special identifiers, such as hash algorithms or database records, etc., which are not listed here one by one.

[0031] The timestamp of the current system time is a value indicating the current system time, in seconds or milliseconds, indicating the time of the current device since a fixed time point. To a certain extent, the timestamp can ensure the order and uniqueness of the ID. In this embodiment, the timestamp format is yyyyMMddHHmmss, which can be pre-set in the configuration file.

[0032] The server IP address is a network identifier assigned to the server, which is an IPv4 or IPv6 address. Taking IPv4 as an example, when the address is 192.168.1.1, the last character of the corresponding number of characters is intercepted starting from the last separator as the server IP information in the application ID code of this embodiment.

[0033] The machine code is a hardware identifier. In this embodiment, the machine code can be a 6-byte MAC address, which is used to uniquely identify a device in the network. The MAC address is a unique identifier at the hardware level, and the MAC addresses of different devices are unique. Therefore, including the machine code can improve the uniqueness of the ID, and at the same time, it can be tracked on which machine the ID was generated, which is convenient for system management and troubleshooting.

[0034] The process ID is a unique identifier assigned by the operating system to each running application or process. Each process has a unique PID during its life cycle. Therefore, by including the process ID on the same machine, it can ensure that the IDs generated by different processes will not conflict. Therefore, using the current application process ID can facilitate subsequent logging and troubleshooting.

[0035] In addition, in this embodiment, a type of code needs to ensure security and unpredictability, so a random number is set to avoid ID duplication in extreme cases. Furthermore, the use of random numbers can also prevent the application ID code from being guessed regularly, preventing others from tracing the information corresponding to the code based on the application ID code, such as order number, document code, and business transaction volume.

[0036] An auto-incremental sequence number is a number that starts from a certain initial value and increases each time a new ID is generated. It can be globally unique or set independently on each server. Using an auto-incremental sequence number can help with subsequent sorting and query operations.

[0037] S208: Generate a corresponding application code according to the coding identification information, and return the application code to the client.

[0038] Among them, the application code is used to uniquely identify the client's coding instructions. The first type of identification information corresponds to the generated first type of application code. The first type of application code is more secure without rules. The second type of identification information corresponds to the generated second type of application code. The second type of application code increments to ensure business needs that have certain requirements for the increment of the code. The application code generated according to the requirements of the coding instruction can be shorter in length for easy storage, or increase in trend for easy query. The application code is returned to the client in the form of a string, and is stored in the database table of the corresponding business according to the coding instruction; when an error occurs in the generation, a unified exception is thrown for processing.

[0039] In one embodiment, the encoding instruction includes a custom prefix character; the step of determining the corresponding encoding category according to the encoding instruction includes: judging whether the custom prefix character in the encoding instruction conforms to the preset encoding; if so, determining the corresponding encoding category according to the custom prefix character; if not, determining that the encoding instruction is to return an invalid instruction and notifying the client.

[0040] Among them, the client's coding instruction is passed in by the business system. In this embodiment, the preset code is the first letter of the default identification of the incoming coding instruction. For example, the coding category is determined according to the document code starting with G or O. G can represent a general document, which is suitable for most business scenarios; O represents an order document, which is suitable for order-related businesses. Accordingly, other prefix characters or suffix characters can also be customized as preset codes according to business needs, which are not listed here one by one.

[0041] In one embodiment, the auto-increment sequence number is generated by a auto-increment counter that monotonically increases with a preset step size.

[0042] Among them, the initial value of the self-incrementing sequence number can be set to a random number, and the preset step size in each server can be set independently. By using the self-incrementing sequence number, services with special requirements for ID sequence can be implemented.

[0043] In one embodiment, each information in the coding identification information is configured with a corresponding interval and the number of character bits in the interval; the step of generating the corresponding application code according to the coding identification information includes: obtaining the interval and the number of character bits corresponding to each information in the coding identification information; configuring each information in the coding identification information according to the interval and the number of character bits corresponding to each information to generate the corresponding application code.

[0044] In one embodiment, the step of configuring the server IP information according to the interval and the number of interval character bits corresponding to the server IP information includes: taking the last separator of the server IP information as the starting point to obtain the number of corresponding last character bits; when the number of last character bits is less than the number of interval character bits, the last character is right-shifted and padded with zeros so that the number of last character bits after the padding is equal to the number of interval character bits.

[0045] In this embodiment, only a certain number of characters of the server IP information need to be intercepted in the application code, and the corresponding number of last character digits can be obtained from the last separator as the starting point. The last separator can be a dot or a slash, etc. The last character is right-shifted and filled with zeros through the right shift operation to obtain the corresponding number of character digits. For example, the interval character number of the server IP information is set to 3 digits, the server IP information is 192.168.60.20, and the last character obtained is 020.

[0046] In one embodiment, when the application code corresponds to a type of code, the character number of the timestamp is set to 12 bits; the character number of the machine code is set to 2 bits; the character number of the current application process number is set to 2 bits; the character number of the server IP information is set to 3 bits; and the character number of the random number is set to 5 bits.

[0047] In this embodiment, the identification information of each interval is spliced ​​into an application code with 24 characters. The 12 bits of the timestamp are the last 12 bits of the current system time, accurate to seconds. The timestamp format is yyyyMMddHHmmss. The machine code takes the last two digits of the local machine code, and the current application process number takes the last two digits of the local application process number. Combined with random numbers, a highly unique and traceable application ID code can be generated, which can achieve 9999 codes generated concurrently on a single machine in seconds.

[0048] In one embodiment, when the application code corresponds to the second type of code, the character digits of the timestamp are set to 7 digits; the character digits of the server IP information are set to 4 digits; and the character digits of the auto-increment sequence number are set to 4 digits.

[0049] In this embodiment, the identification information of each interval is spliced ​​into a 15-character application code, and the specific limitations of obtaining the timestamp and server IP information can be found above. Among them, the timestamp provides sequentiality and uniqueness in time, and the self-incrementing sequence number ensures that multiple IDs generated at the same timestamp and on the same server will not conflict, which can be applied to high-performance and high-sequential scenarios.

[0050] Based on the same inventive concept, the embodiment of the present application also provides an application ID code generation device for implementing the above-mentioned application ID code generation method. The implementation solution provided by the device to solve the problem is similar to the implementation solution recorded in the above-mentioned method, so the specific limitations in one or more application ID code generation device embodiments provided below can refer to the above-mentioned limitations on the application ID code generation method, and will not be repeated here.

[0059] In one embodiment, the identification module 303 also includes a separation module, which is used to obtain the number of bits of the corresponding last character starting from the last separator of the server IP information; when the number of bits of the last character is less than the number of bits of the interval character, the last character is right-shifted and padded with zeros so that the number of bits of the padded last character is equal to the number of bits of the interval character.
