The difference between a read-write transaction and a read-only transaction for spring

The problem today is that hibernate and spring integration, in the same transaction, if the value of the associated object is changed, automatically updates to the database, but I do not want him to update to the database. The end result is that the transaction setting spring is read-only (read-only= ' true ') to solve the problem.

Set as read-only transactions, you can make the persistence layer attempt to optimize the data operations, such as hibernate for read-only transactions, and some database connection pools and JDBC drivers are also specifically optimized for read-only operations (flush).

The last time Oracle read-only transactions are confused with this transaction, there is a good contrast here. Oracle Read-Only transactions
