BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Figure 1 It is a flow chart provided in an embodiment of the present application. DETAILED DESCRIPTION

[0037] The present application provides a method for data synchronization based on JAVA middleware, comprising the following steps:

[0038] Step 1: Set up a data synchronization module in the JAVA middleware to implement data synchronization processing.

[0039] As the core component of JAVA middleware, the data synchronization module is mainly responsible for the management, execution and monitoring of data synchronization tasks. This module adopts synchronization algorithms and strategies to ensure the real-time, consistency and integrity of data.

[0040] 1.1 Data synchronization module composition

[0041] The data synchronization module is mainly composed of the following four sub-modules:

[0042] Synchronization task management submodule: responsible for receiving, parsing and scheduling data synchronization tasks

[0043] Data source connection submodule: responsible for establishing connections with the source database and target database, and performing data extraction, conversion and loading operations.

[0044] Data synchronization execution submodule: actually executes data synchronization operations according to synchronization rules.

[0045] Synchronization monitoring and logging submodule: records the status and logs of the synchronization process in real time, providing a basis for troubleshooting and performance optimization.

[0046] 1.2 Implementation Principle

[0047] The data synchronization module adopts a synchronization mechanism based on event triggering or scheduled tasks. When the data in the source database changes (such as addition, modification, deletion), it sends a signal to the synchronization task management submodule and performs the corresponding data synchronization operation. Then, through the task scheduling algorithm, the specific data is obtained, and according to the difference, the execution of data synchronization is assigned to the data synchronization execution submodule for actual data synchronization operation.

[0048] During the synchronization process, the module will use incremental synchronization or full synchronization, depending on the size of the data change and the synchronization frequency. At the same time, the module also has data verification and conflict resolution mechanisms to ensure the accuracy and consistency of synchronized data.

[0049] Step 2: Receive the data synchronization request sent by the data source, parse the request parameters, and obtain the data information to be synchronized.

[0050] Step 3: Build a data synchronization task based on the data information to be synchronized, and add the task to the task queue for processing.

[0051] Step 4: Take out the pending data synchronization tasks from the task queue, and perform data synchronization processing through the data synchronization module of the JAVA middleware.

[0052] 4.1 Take out pending tasks

[0053] The working thread of the data synchronization module will continuously monitor whether there is data that needs to be processed. Once a data synchronization task is found to be processed, it will immediately execute the task and perform subsequent processing.

[0054] 4.2 Parsing task information

[0055] After taking out the task, the module first parses the information in the task, including data synchronization rules, source database connection information, target database connection information, synchronization data fields, etc. Subsequent data synchronization is performed based on this information.

[0056] 4.3 Establishing a database connection

[0057] Based on the connection information obtained through parsing, the data source connection submodule will establish connections with the source database and the target database, including verifying the user name and password, testing whether the connection is available, and whether the target data table fields can obtain data.

[0058] 4.4 Data Extraction and Conversion

[0059] After the connection is successful, the data synchronization execution submodule extracts the data to be synchronized from the source database. According to the synchronization rules, it first determines whether there is consistent data and difference data, and converts and maps the difference data to meet the format and requirements of the target database.

[0060] 4.5 Data loading and verification

[0061] The extracted and converted data is loaded into the target database. During the loading process, data integrity and consistency verification is performed to avoid synchronization failures or differences after data conversion.

[0062] Step 5: During the data synchronization process, the synchronization status is recorded in real time, and the synchronization results are fed back to the data source after the synchronization is completed.

[0063] Step 6: Based on the synchronization results, determine whether the data synchronization is successful. If the synchronization is successful, end the synchronization process; if the synchronization fails, perform corresponding error processing based on the cause of the failure and try data synchronization again.

[0064] Positive effects:

[0065] By setting up a data synchronization module in the JAVA middleware, unified management and control of data synchronization is achieved, and the efficiency of data synchronization is improved.

[0066] By building a data synchronization task and adding it to the task queue to wait for processing, asynchronous processing of data synchronization is achieved, reducing synchronization delay.

[0067] By recording the synchronization status in real time and feeding back the synchronization results after the synchronization is completed, real-time monitoring and error handling of the data synchronization process are achieved, reducing the synchronization error rate.

[0068] See also Figure 1 In other embodiments of the present application, the method includes the following steps:

[0069] 110. JAVA middleware settings and initialization

[0070] First, you need to set up a data synchronization module in the JAVA middleware environment. This module can exist as a component or service of the middleware and is responsible for handling all logic related to data synchronization. During initialization, the module needs to configure relevant parameters, such as data source connection information, synchronization rules, synchronization frequency, etc.

[0071] 120. Receive data synchronization request

[0072] When an external system or data source needs to initiate a data synchronization request, the request is sent to the JAVA middleware through a predefined interface or message queue. The data synchronization module listens to these requests and once received, it immediately parses the parameters, including the data table, fields, conditions, etc. to be synchronized.

[0073] 130. Build data synchronization tasks

[0074] According to the parsed synchronization parameters, the data synchronization module builds the corresponding data synchronization tasks. Each task contains specific synchronization operations, target data sources, execution conditions and other information. After the construction is completed, the task is added to the task queue and waits for execution.

[0075] 140. Asynchronous processing of data synchronization tasks

[0076] There are one or more worker threads inside the middleware, which are responsible for taking out pending tasks from the task queue and executing them. After taking out the task, the thread connects to the corresponding data source according to the information in the task, performs data extraction, conversion, loading and other operations, and synchronizes the data from the source end to the target end.

[0077] 150. Record synchronization status and feedback

[0078] During the data synchronization process, the middleware records the execution status of each task in real time, including the start time, end time, amount of synchronized data, error information, etc. After the synchronization is completed, the middleware feeds back the synchronization result (success or failure) and related statistical information to the data source or external system that initiated the request.

[0079] 160. Error handling and retry mechanism

[0080] If an error occurs during synchronization, the middleware will handle it accordingly based on the error type. For recoverable errors (such as a brief network outage), the middleware will try to reconnect and continue synchronization; for unrecoverable errors (such as data format mismatch), the middleware will record the error details and notify the administrator. At the same time, the middleware can set a retry mechanism to automatically retry failed synchronization tasks under certain conditions.

[0081] 170. Monitoring and Logging

[0082] In order to ensure the reliability and stability of data synchronization, the middleware provides a monitoring function that allows you to view the status of the task queue, the tasks being executed, historical synchronization records, etc. in real time. In addition, the middleware will also record detailed logs, including detailed information and error records for each synchronization, to facilitate subsequent troubleshooting and performance optimization.
