Spring @JpaDataTest 无事务

Question

我正在尝试使用@JpaDataTest 来测试我的存储库

我是这样使用它的：

@RunWith(SpringRunner.class)
@DataJpaTest
public class MyTest {
    @Autowired
    private TestEntityManager entityManager;
    @Autowired
    private MyRepo myRepo;

    @Test
    public void myTest() {
        assertEquals(0, myRepo.findAll().size());
        entityManager.persist(new MyEntity());
        //entityManager.flush();
        assertEquals(1, myRepo.findAll().size());
    }
}

测试未通过，因为第二个 findAll return 0 个实体

如果我删除评论以刷新

我遇到了一个错误

javax.persistence.TransactionRequiredException: no transaction is in progress

Answer 1

我找到原因了...

@SpringBootConfiguration
@EnableAutoConfiguration
@ComponentScan
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

如果我删除 @ComponentScan 它会起作用...
