the method of entering the library in service needs to be tested in the case of multithreading, and then two threads are opened to execute the service method in a loop, but there are a lot of problems, including the following situations.

1. both threads are halfway through execution and then terminate with an error. The database has several pieces of data
2. both threads are executed only once, and the database has one piece of data each
3. Database has no data
