SpringBoot 事务未提交排查指南：代码问题分析

The provided code seems to be a utility class for managing transactions in a Spring Boot application. Here are a couple of things you can check to troubleshoot the issue:

1. Make sure that you have properly configured and injected the 'DataSourceTransactionManager' bean into this class. You can do this by annotating the class with '@Component' or manually creating an instance of 'DataSourceTransactionManager' and injecting it using constructor or setter injection.

2. Verify that you are using this 'TransactionUtil' class correctly in your code. Ensure that you are calling the 'create()' method to start a new transaction, performing your database operations within the transaction, and then calling either 'commit()' or 'rollback()' to complete the transaction.

3. Check if you have any exceptions occurring during the execution of your code. If an exception occurs and is not caught, the transaction might not be committed, leading to the issue. Make sure to handle exceptions appropriately and call 'rollback()' in case of an exception.

4. Check if you have any nested transactions. The 'PROPAGATION_REQUIRES_NEW' propagation behavior used in 'create()' method creates a new transaction even if there is an existing one. If you are expecting the outer transaction to be committed first, consider using a different propagation behavior like 'Propagation.REQUIRED'.

5. Verify that you have proper error handling and logging in place to capture any exceptions or errors related to transactions. This can help in identifying the root cause of the issue.

By reviewing these aspects, you should be able to identify and address any potential issues with the transaction management in your Spring Boot application.
