Spring JPA (Hibernate) Entity Manager Connection Pool Management

With Spring JPA utilization of the Hibernate Entity Manager, the return of connections to the connection pool occurs upon transaction completion. This process is handled seamlessly by the interaction between Spring components and Hibernate's JDBC connection management logic.

Spring's TransactionInterceptor intercepts transactional method calls, delegating transaction handling to the JpaTransactionManager. The JpaTransactionManager associates the current transaction with an EntityManager, ensuring that all participating DAOs share the same Persistence Context.

Upon transaction commit or rollback, the JpaTransactionManager delegates the transaction termination to the Hibernate Session (Entity Manager). The Session's close method triggers the release of the logical JDBC connection.

The logical connection delegates close operations to the configured connection provider (DataSourceConnectionProvider). The connection provider, in turn, closes the JDBC connection proxy, returning it to the connection pool.

For RESOURCE_LOCAL transactions, the hibernate.connection.provider_disables_autocommit property should be set to ensure database connections are acquired lazily rather than at the start of a transaction.
