(Detailed description) Write operations are not allowed in read-only mode (FlushMode. NEVER/MANUAL): Turn your Session

Yesterday, we found that the previous normal function reported an error. The error log is as follows:

DEBUG debugging finds that an error is reported when the saveOrUpdate () method is called at the DAO layer.

Compare the log:

Org. springframework. dao. invalidDataAccessApiUsageException: Write operations are not allowed in read-only mode (FlushMode. NEVER/MANUAL): Turn your Session into FlushMode. COMMIT/AUTO or remove 'readonly' marker from transaction definition.

Knowing that there is a problem with configuring Hibernate transaction management, we found that the following line was mistakenly deleted by someone else. In addition, this sentence is OK.

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

If this row does not exist, transaction management follows the bottom by default.

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

In this way, the "write operation" cannot be performed:
