IDEA performs the Test operation, resulting in duplicate data when data is inserted

The problems I encountered and the solutions:
Solution: Open the File->Settings in the upper right corner of IDEA, search for maven, open the Runner in the maven directory, and find the Delegate IDE build/run actionsto Maven option, uncheck the previous check!!!
Tick off!!!

Delegate IDE build/run actions to Maven: Hand over the build and run operations in the IDE to Maven. If the project is not checked, the build and run operations are handed over to the IDE, which may lead to the inability to find the relevant jar packages in the maven repository during build and run.After checking, the operations such as building and running the project are directly handed over to maven.However, this will lead to duplicate data when inserting database data. During the actual measurement, it is found that both maven and IDEA have run the project, resulting in duplicate data.

Note: The above explanation is only my own understanding
