Description

Technical Field

[0001] The present invention relates to big data processing technology, and in particular to a data dictionary management method, system and storage medium based on configuration files. Background Art

[0002] Data dictionary refers to the definition and description of data items, data structures, data flows, data storage, processing logic, etc. Its purpose is to provide detailed descriptions of each element in the data flow diagram. The data dictionary is used for simple modeling projects. Objects of the same type represented by object codes and object information are called dictionary items. In the process of integrated platform development, many data dictionary items need to be maintained. The dictionary code is saved with the business data flow. When displaying data, the dictionary code needs to be converted into dictionary information that is easy for users to understand.

[0003] In the process of application development, dictionary items are usually stored in data dictionary tables, enumeration types, or XML. Storing data dictionary items in data dictionary tables facilitates dictionary data changes. If users need to add or change dictionary configuration items, they only need to modify the data dictionary table records without modifying the code; however, there are problems: 1) When querying business data, it is necessary to left-link the dictionary table, which makes SQL maintenance complicated; 2) There are performance issues in the dictionary code conversion process, especially when the business data flow and the data scale in the data dictionary table are large, the query is slow, resulting in too much time consumed in the process of converting from dictionary code to dictionary information.

[0004] In the prior art, in order to solve the above problem, by storing dictionary items of the same type in an enumeration class, all dictionary items are loaded when the system starts, and the memory is directly read, so that the dictionary encoding conversion speed is accelerated. However, the disadvantages are as follows:

[0005] 1) When there are many dictionary types, a large number of enumeration classes need to be created, which is poor in readability;

[0006] 2) Dynamic update of dictionary data is not supported. If dictionary data is updated, the service needs to be republished for the modification to take effect;

[0007] 3) Use XML to store data dictionary items. For example, XML has poor readability and maintainability compared to JSON configuration. The data in XML is surrounded by a large number of tags, which reduces the data payload.

[0008] 4) The conversion from dictionary item encoding to dictionary item information needs to be manually processed.

[0009] Therefore, there is an urgent need for a data dictionary management method with good readability and flexibility. Summary of the invention

[0053] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0054] In order to improve user coding efficiency, the present invention provides a data dictionary management method based on configuration files. Figure 1 The flow chart of the embodiment of the data dictionary management method based on the configuration file of the present invention is shown. Figure 1 As shown, the method can be executed by a device, and the device can be implemented by software and / or hardware.

[0055] The data dictionary management method based on the configuration file includes: step S110 to step S140.

[0056] S110: Obtain business data request.

[0057] In a specific embodiment, before the step of obtaining the user's service data request, dictionary items are pre-configured in the configuration center; the method of pre-configuring dictionary items in the configuration center includes: steps S10-S40.

[0058] S10. Create a namespace in the configuration center.

[0059] Specifically, create a namespace: In the microservice system architecture, each service that needs to use dictionary items needs to create a separate Namespace in the configuration center and name it custom_prop.

[0060] Specifically, through a general servlet container, requests are classified through reflection and proxy, and dictionary item class requests only correspond to one general dictionary item servlet container.

[0061] Because the servlet container is not a Spring Bean, Spring AOP is invalid for methods in Servlet. In order to implement Spring AOP to intercept Servlet, the following operations need to be performed on the servlet container: call the Spring Bean method in the Servlet method, and achieve this function by implanting aspects in the Spring Bean; use Spring MVC's interceptor Interceptor to perform functional intervention on Servlet requests: 1) define the Java class as the interceptor Bean; 2) declare the Bean as the interceptor in Dispatch-servlet.xml.

[0062] S20. Configure a dictionary item set and a configuration specification of the dictionary item set in a namespace; wherein the dictionary item set includes a plurality of dictionary items.

[0063] The dictionary item set includes KEY and VALUE, where:

[0064] The KEY is a unique identifier of the dictionary item set in the namespace;

[0065] The VALUE includes a business table name, a business field name and a dictionary data set; the dictionary data set is formed by merging dictionary item metadata in a dictionary item storage container according to the business table name and the business segment name.

[0066] Specifically, the configuration dictionary item set is composed of multiple dictionary items, which form a set of dictionary item sets. The dictionary item set is configured in the namespace named custom_prop according to the configuration management specifications of the JAVA configuration file. The KEY of the dictionary item set is named according to the custom business specifications, and the Namespace is guaranteed to be unique. The VALUE of the dictionary item set is configured in a JSON structure, which contains four elements, namely business group, business name, business field name, and dictionary data set.

[0067] Business grouping is used to mark the group to which the dictionary item belongs. It is mainly used to realize dictionary data aggregation of complex multi-business modules, and realize group storage and retrieval. The business group name is specified by the group field. The dictionary data items of the same business group are set with the same business group name. For the convenience of maintenance and management, they are usually named after the business module name. When the background program loads data, it loads and merges the same data blocks into the same data unit according to the business group name to provide retrieval services.

[0068] Business name, used to mark the name of the business module to which the dictionary item belongs, is the basic unit for dividing data dictionary items. It corresponds to the business data table of the relational database and is specified through the table field, usually named after the business data table name.

[0069] Business field name, used to mark the business classification of dictionary items, corresponds to the business data table field of the relational database. It is specified by the column field, and uniquely determines a set of dictionary item data together with the business group, business name, and business field name.

[0070] A field set is a data set consisting of dictionary items, defined using dict fields.

[0071] Dictionary items are saved using Node nodes consisting of code and name. The dictionary item code is saved in code, and the dictionary item name is saved in name.

[0072] S30. Configure a listening interface and a service interface for registering Watch events; wherein both the listening interface and the service interface correspond to the dictionary item set.

[0073] The Watch event includes a dictionary item startup event and a dictionary item set update event. That is, the monitoring step of the monitoring interface is: when the monitored application is started or a dictionary item update action occurs, a Watch event is generated.

[0074] After the dictionary item collection data is configured, the application registers the Watch event through the configuration listening interface (ApolloConfigChangeListener). When the application starts or the configured dictionary item is updated, the Watch event will be generated and the latest data will be pushed to the memory of the application that subscribes to the event, so that the application can dynamically obtain the changed dictionary data in real time. The detailed process is as follows: Integrate the microservice configuration center and complete the dictionary item collection configuration according to the above step S20. Inject the Spring application context through the ApplicationContextAware interface, listen to the Namespace named custom_prop through the configuration listener of the configuration center, and save the monitored dynamic data in the memory of the Spring application context for data storage.

[0075] S40. Configure json memory to store update data of the dictionary item set.

[0076] After the dictionary item data is updated, the listener that has gone through the above steps obtains the changed data and saves it in memory. For ease of application, the data needs to be processed and converted, and the converted data is stored in a dynamic array.

[0077] The process of updating data of the JSON memory storage dictionary item set includes:

[0078] When the monitoring interface monitors that the corresponding dictionary item set is updated, a Watch event corresponding to the update is generated, and the latest configuration data of the updated dictionary item set is written into the service interface;

[0079] The corresponding dictionary item configuration data in the namespace is read through the service interface to determine the corresponding dictionary attribute value; which includes obtaining a dictionary attribute name list; traversing the dictionary attribute name list, and then determining the corresponding dictionary attribute value.

[0080] The latest configuration data and dictionary attribute values ​​are serialized to form dictionary item metadata; wherein the setting process of the dictionary item storage container is as follows: a dynamic array is initialized in the memory of the application as a dictionary item storage container for storing the converted dictionary configuration data. The dictionary item metadata is saved in the dictionary item storage container.

[0081] In the specific implementation process, a dynamic array is initialized as a dictionary item storage container, i.e., a Servlet container, for storing the converted dictionary configuration data; when a monitoring event occurs, the latest configuration data will be written into the configuration service interface (ConfigService), in which the dictionary item configuration data (Config) configured by Namespace is read; in the dictionary item configuration data (Config), the data dictionary attribute name list (PropertyNames) is read; the dictionary attribute name list (PropertyNames) is traversed, and the dictionary attribute value is taken out according to the dictionary attribute name in the dictionary item configuration data (Config), and serialized into dictionary item metadata (DictProp), and saved in the dictionary item storage container. After the dictionary item storage container data is saved, the dictionary data set is merged according to the business table name and the business field name to adapt to the scenario of splitting the configuration of a large amount of dictionary sets. The class instance of the dictionary value is returned to the user.

[0082] S120 , intercepting and processing the acquired business data requests of the users by using aspect programming technology, so as to filter out the business data requests containing dictionary item requirements.

[0083] Specifically, the aspect technology is AOP cross-cutting technology; it is irrelevant to the core business, but it encapsulates the logic or responsibility commonly called by the business modules, which is convenient for reducing the system's duplicate code, reducing the coupling between modules, and is conducive to future operability and maintainability. By using AOP aspect technology, the dictionary demand business and the core business logic are separated, the aspect is configured through configuration files or annotations, and the filtering conditions are set for the aspect. The filtering conditions are the methods in the program, which means that when these methods in the program are called, the methods of the dictionary item aspect will be called to read the dictionary items, which is equivalent to a mechanism that triggers the dictionary items when the filtering conditions are met.

[0084] In a specific embodiment, aspects and entry points are set through configuration files, trigger methods associated with entry points are set, and the mapping relationship between core business functions and trigger functions is configured. Once the trigger method is called, the aspect will be entered, and related functions will be executed before, after, or in exception situations of the trigger method. The specific steps include: configuring aspect information for the log class LogAop, configuring logAopBean in applicationContext.xml to be the bean for configuring the log, and providing it to the IOC call. aop:aspect id="logAspect" defines an aspect. Define the log class and implement the pre, post, exception, return and other methods in the log class. Use annotations instead of configuration files to tell the IOC container the mapping relationship between aspects, entry points, trigger functions and core business methods. In this application scenario, Spring AOP is used to intercept data requests for dictionary requirements.

[0085] S130, sending the service data request to a dictionary encoder, and sending a query request to a dictionary item container through the dictionary encoder; wherein the dictionary item container is used to obtain a dictionary value corresponding to the query request, and return the dictionary value to the dictionary encoder;

[0086] The dictionary encoder is used to obtain the dictionary value encoded into the dictionary item container, that is, the dictionary encoder is used to obtain the dictionary value corresponding to the above dictionary request data from the dictionary item container. After the dictionary encoder receives the dictionary request data intercepted by the AOP, it sends a query request to the dictionary item container, and the dictionary item container finds the dictionary value corresponding to the dictionary request according to the query request, and then returns the dictionary value to the dictionary encoder.

[0087] S140. The dictionary encoder calls a CGLib dynamic generator according to the dictionary value, and the CGLib dynamic generator is used to dynamically generate a class instance containing the dictionary value according to the dictionary value, and return the class instance of the dictionary value to the user.

[0088] The dictionary encoder calls the CGLib dynamic generator according to the obtained dictionary value, and the CGLib dynamic generator dynamically generates a class instance containing the dictionary value (i.e., a proxy embodiment) according to the dictionary value. The dynamic proxy generator returns the generated class instance containing the dictionary value to the dictionary encoder, and then returns it to the user.

[0089] In a specific embodiment, after the data is stored, when there is a business data request, the aspect-oriented programming technology is used to intercept and process it. For requests containing dictionary requirements, the encoder logic is called for processing. The dictionary encoder stores the intercepted dictionary item code in the dictionary item storage container, reads the dictionary value corresponding to the dictionary code, and then calls the dynamic proxy generator, using the dynamic proxy generation technology to dynamically generate a class instance containing the dictionary value, and returns a response to the caller. Among them, the class instance of the dictionary value is to create a class and create an object of the class (instantiate the class), and the instantiation of the class is similar to the function call method.

[0090] The configuration file-based data dictionary management method of the present invention manages dictionary items in the configuration file, decouples them from business codes, is easy to maintain, and uses event monitoring technology to support dynamic updates, so that the updated latest dictionary item configuration can take effect without publishing services. This proposal intercepts requests with dictionary requirements through aspect-oriented programming technology, searches for dictionary values ​​in dictionary item storage containers according to dictionary item codes, and then dynamically generates a return body containing dictionary values ​​using dynamic proxy technology, and returns the new entity to the user, so that there is no need to pay attention to the encoding conversion of dictionary items during the application microservice development process, and realizes the decoupling of dictionary item management and business processing, achieving the technical effect of improving the maintenance efficiency of dictionary items.

[0091] Figure 2 The schematic diagram of the principle of the data dictionary management method based on the configuration file of the present invention is shown. Figure 2 As shown,

[0092] The present invention is a data dictionary management method based on configuration files. When there is a business data request, the aspect-oriented programming technology (AOP) is used to intercept and process it. For requests containing dictionary requirements, the logic of the encoder is called to process it. The dictionary encoder stores the intercepted dictionary item code in the dictionary item storage container, reads the dictionary value corresponding to the dictionary code, and then calls the dynamic proxy generator, uses the dynamic proxy generation technology to dynamically generate a proxy implementation example containing the dictionary value, and returns a response to the caller.

[0093] In summary, the present invention intercepts requests with dictionary requirements through aspect-oriented programming technology, searches for dictionary values ​​in dictionary item storage containers according to dictionary item codes, and then dynamically generates a return body containing dictionary values ​​using dynamic proxy technology, and returns the new entity to the user. The calculation processing of dictionary items through the data dictionary management method based on configuration files is pre-executed in memory, and the data calculation results are cached in memory after execution, achieving the technical effect of improving processing efficiency and response speed.
