Is SessionFactory a thread-safe object in Hibernate?

回答：

Yes, in Hibernate, the SessionFactory is designed to be a thread-safe object. It is intended to be a singleton in your application, meaning that you should create one instance of SessionFactory and share it across multiple threads.

The SessionFactory is responsible for creating Session instances, which are not thread-safe. Each Session should be used by a single thread at a time. Therefore, while you can safely share a SessionFactory among multiple threads, you should ensure that each thread uses its own Session instance.

In summary:

  • SessionFactory: Thread-safe, can be shared across threads.
  • Session: Not thread-safe, should be used by a single thread only.

This design allows for efficient resource management and performance optimization in applications using Hibernate.
