Spring Data and DB transaction isolation levels conflict
In the spring date, when using the @Transactional annotation, it is possible to change the transaction isolation level: Read Uncommitted, Read Committed, Repeatable Read, Serializable. But there are also isolation levels on the database layer. What level will be applied if there is a mismatch between these layers? For example, at the base level, there is a repeatable read, and spring date uses a less strict read committed.
