The Spring Data JPA is developed based on Hibernate, so building entity and mapping relationships requires a good understanding:------Entity Manager Entity Manager Entitymanager is the entity's Bridge to the database (and the transaction works together), Equivalent to the sqlsession in the Session,mybatis in Hibenrtae.

Note: JPQL does not support the use of INSERT;(2) Write JPQL statements in @Query annotations, but must be decorated with @Modifying. To notify Springdata that this is an UPDATE o

Abnormal recurrence: The JPQL statement is as follows: Select G from Entity g where G.codeurl =: Codeurl ORDER by g.createtime DESC limit 1 Exception Reason: Limit is specific to certain databases (for example: MySQL), but HQL is for all hibernate-supported databases, that is, MySQL has a limit on the number of returned records, and perhaps other databases are not limit (for example:
