Unit testing of the controller layer of spring MVC using a mock

Overall goal: To achieve the purpose of automated test interface

Project composition: Spring MVC + hibernate + MySQL

How do I use mocks for unit testing of interfaces?

Implementation ideas: Replace MySQL with H2 database, before hibernate datesource configuration is MySQL, now configured as H2, so the test database is clean, because in memory. Clear the In-memory database before each JUnit mock test

Implementation code:
