Question

我正在使用JPA存储库，并且在我的代码中还使用了程序化事务管理，如下所示

public class PipelineJobProcessor {

     @Autowired
    private EntityManagerFactory emf;

    @Autowired
    private PipelineJobRepository pipelineJobRepository; //JPA repository

    @Transactional
    public void someMethod () {
        ..
        pipelineJobRepository.save(entity);
    }

    .
    .
    //Manual transaction management
    private void savePipelineJob(PipelineJob pipelineJob) {
        EntityManager em = emf.createEntityManager();
        EntityTransaction tx = em.getTransaction();
        try {
            tx.begin();
            pipelineJobRepository.save(pipelineJob);
            tx.commit();
        } catch (Exception e) {
            tx.rollback();
            throw e;
        } finally {
            em.close();
        }

    }
}

但是在几次API调用之后，似乎连接池没有任何空闲连接，并且出现以下错误：

关于此的任何提示吗？

JPA EntityManager close（）不会释放与池的连接吗？
