Hibernate线程中是否有CUD操作安全？

Question

Could you please explain how CUD operations in Hibernate work with multithreading? And are they threadsafe? For example, two threads create users in same time, what will be with id? Is there any synchronization?

Answer 1

You have to consider the hibernate session only. Its not sharable among threads. So each thread will have its own db session object and execute the query. Thats it. Nothing with hibernate CUD its all depends on how you have created your DAO / Repository objects with proper db session handling.
