Java 使用Spring JPA JUnit在测试环境中持久化/提交不起作用

Java 使用Spring JPA JUnit在测试环境中持久化/提交不起作用,java,spring,hibernate,jpa,junit,Java,Spring,Hibernate,Jpa,Junit,我正在尝试设置一个基本的JPA插入测试。但数据库中没有保存任何内容。 DB是Postgresql。Hibernate用作持久性提供程序 非常感谢 @Entity public class Currency { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) protected Integer id; @Column private String code; @Column

我正在尝试设置一个基本的JPA插入测试。但数据库中没有保存任何内容。 DB是Postgresql。Hibernate用作持久性提供程序

非常感谢

@Entity
public class Currency {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    protected Integer id;    

    @Column
    private String code;

    @Column
    private String name;
...
}

我注意到日志文件中有以下内容:

java.lang.IllegalStateException: Cannot execute getTransaction() on a container-managed EntityManager
    at 
...
...
所以,我删除了

entityManager.getTransaction().commit()

来自CRUDServiceBean中的persistAndCommit(T)方法

这删除了异常,不再有其他异常。 测试的输出显示以下内容:

Hibernate: insert into Currency (code, name) values (?, ?)
但是,尚未使用表CURRENCY写入任何记录


就像测试完成后,Hibernate删除插入的记录一样

如果您的测试成功通过,并且没有得到任何异常,那么请对每个测试类使用@TransactionConfiguration(defaultRollback=false),或者对每个测试方法使用@Rollback(false)。 在spring测试上下文中,事务测试默认情况下将回滚

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={
  "test-context.xml"})
@TransactionConfiguration(defaultRollback=false)
@Transactional
public class SampleCrudTest {

    @Autowired
    private SampleCrud sampleCrud;

    @Before 
    public void onSetUpInTransaction() throws Exception {
        //Populate Test Data
    }


    @Test
    public void registerSample() {

        Sample sample = new Sample("foo");
        sampleCrud.save(sample);
        assertNotNull(sample.getId());
    }

}
您可以使用
@Rollback(false)

e、 g:


这对我来说很有效,请确保启动事务并提交事务

public Transaction startTransaction(Session session) throws HibernateException {
        return session.beginTransaction();
    }

...... your test code goes here......

public void endTransaction(Session session) throws HibernateException {

        if (session != null) {
            session.getTransaction().commit();
        }
    }

尝试将
entityManager.merge(t)
添加到
entityManager.persist(t)
之前的
persistAndCommit
中,这意味着它不起作用?你有错误吗?或者,你期望得到一些不同的结果吗?请分享预期与实际的行为。我在测试类上添加了@TransactionConfiguration(defaultRollback=false),现在我在表CURRENCY中看到了一个新条目。非常感谢你的帮助!!!请您可以选择我的答案作为正确答案,这有助于其他人解决问题。@现已弃用。使用
@Transactional(Transactional.TxType.REQUIRES_NEW)
@Rollback(false)
@DataJpaTest
@RunWith(SpringRunner.class)
@Rollback(false)
abstract class RepositoryTest {
  ...
}

class UserReportitoryTest extends RepositoryTest {

    @Autowired
    UserRepository repository;

   @Test
   void it_should_save_the_user() {
     repository.save(user);
   }
}
public Transaction startTransaction(Session session) throws HibernateException {
        return session.beginTransaction();
    }

...... your test code goes here......

public void endTransaction(Session session) throws HibernateException {

        if (session != null) {
            session.getTransaction().commit();
        }
    }
