The comparison log says:

Org.springframework.dao.InvalidDataAccessApiUsageException:Write operations are not allowed in read-only mode ( flushmode.never/manual): Turn your session to
Flushmode.commit/auto or remove ' readOnly ' marker from Transaction de Finition.

Know is configured hibernate transaction management has a problem, really found that the following line was mistakenly deleted, plus this sentence is OK.

<tx:method name= "save*" rollback-for= "Exception" propagation= "REQUIRED"/>

Without this line, transaction management defaults to the bottom

<tx:method name= "*" propagation= "SUPPORTS" read-only= "true"/>

This makes it impossible to write:
