@RunWith(SpringRunner.class)
@CustomTestContext
public class TransactionalTest {
@Autowired
private UserRepository userRepository;
private Log logger = LogFactory.getLog(getClass());
public void doSomething() {
try {
User user = new User();
user.setUsername("test"); // username has unique constraint
userRepository.save(user);
} catch (DataIntegrityViolationException e) {
logger.info("Wrong");
}
}
@Test
@Transactional
public void doTest() {
doSomething();
doSomething();
}
@Test
@Transactional
public void doTest2() {
doSomething();
doSomething();
}
}
当doTest在第二次doSomething调用中遇到DataIntegrityViolationException时，第一个doSomething调用没有回滚，导致用户名为“test”的用户仍然存在，并导致doTest2的两次doSomethong调用抛出DataIntegrityViolationException。
我期望的是，当事务方法遇到异常时，它将回滚到第一个带有 @Transactional 注释的方法运行之前的状态，在上面的情况下，它根本没有向数据库插入任何新用户，因为默认传播值为 REQUIRE。
我将 JpaTransactionManager 日志记录级别设置为 DEBUG 并得到如下控制台:

似乎确实回滚了，但不影响第一个 doSomething 调用。
更新:
我编辑代码如下:
@Transactional
public void doSomething() {
logger.info("First save");
userRepository.save(new User("test", "test"));
logger.info("Second save");
userRepository.save(new User("test", "test"));
}
@Test
@Transactional
public void doTest() {
doSomething();
}
@Test
@Transactional
public void doTest2() {
doSomething();
}
我已将 @transactional 添加到 doSomething() 并让异常从 doSomething 抛出，但得到了相同的结果:

它有行参与事务失败 - 将现有事务标记为仅回滚，但doTest2在第一次userRepository.save()尝试时仍然失败，意味着名称为“test”的用户已经存在。
这是否意味着当同一事务内发生某些异常时，第一个save无法回滚？
CustomTestContxt.java
@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@ContextConfiguration("file:src/main/resources/applicationContext.xml")
@TestPropertySource(
locations = {"file:src/main/resources/application.properties"},
properties = {"mysql.Url = jdbc:mysql://localhost:3306/springtest?characterEncoding=UTF-8&serverTimezone=UTC"})
public @interface CustomTestContext {
}
更新2:
@Test
@Transactional
@Rollback
public void doTest() {
entityManager.persist(new User("test", "test"));
}
@Test
@Tranactional
public void doTest2() {
logger.info(entityManager.find(User.class, 1L));
}
它记录:
INFO c.r.s.test.TransactionalTest - User{id=1, username='test', password='test', roles=[]}
最佳答案
doSomething() 正在捕获异常。
只有在@Transactional注解的方法中抛出RuntimeException时，事务才会回滚。
如果您想保留代码原样，则必须在 doSomething() 中手动回滚事务
TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
第二个选项是将 doSomething() 标记为事务性的，然后不捕获事务。那么事务处理必须在测试方法中完成。
关于java - Spring事务没有正确回滚，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48151514/
