如何在 Spring Boot 测试中强制事务提交? [英] How to force transaction commit in Spring Boot test?

问题描述

如何在 Spring Boot(使用 Spring Data)在运行方法时而不是在方法之后不强制事务提交?

How can I force a transaction commit in Spring Boot (with Spring Data) while running a method and not after the method ?

我在这里读到，在另一个类中使用 @Transactional(propagation = Propagation.REQUIRES_NEW) 应该是可能的，但对我不起作用.

I've read here that it should be possible with @Transactional(propagation = Propagation.REQUIRES_NEW) in another class but doesn't work for me.

有什么提示吗?我使用的是 Spring Boot v1.5.2.RELEASE.

Any hints? I'm using Spring Boot v1.5.2.RELEASE.

@RunWith(SpringRunner.class)
@SpringBootTest
public class CommitTest {

    @Autowired
    TestRepo repo;

    @Transactional
    @Commit
    @Test
    public void testCommit() {
        repo.createPerson();
        System.out.println("I want a commit here!");
        // ...
        System.out.println("Something after the commit...");
    }
}

@Repository
public class TestRepo {

    @Autowired
    private PersonRepository personRepo;

    @Transactional(propagation = Propagation.REQUIRES_NEW)
    public void createPerson() {
        personRepo.save(new Person("test"));
    }
}

推荐答案

一种方法是在测试类中注入 TransactionTemplate，删除 @Transactional 和 @Commit 并将测试方法修改为:

An approach would be to inject the TransactionTemplate in the test class, remove the @Transactional and @Commit and modify the test method to something like:

...
public class CommitTest {

    @Autowired
    TestRepo repo;

    @Autowired
    TransactionTemplate txTemplate;

    @Test
    public void testCommit() {
        txTemplate.execute(new TransactionCallbackWithoutResult() {

          @Override
          protected void doInTransactionWithoutResult(TransactionStatus status) {
            repo.createPerson();
            // ...
          }
        });

        // ...
        System.out.println("Something after the commit...");
    }

或

new TransactionCallback<Person>() {

    @Override
    public Person doInTransaction(TransactionStatus status) {
      // ...
      return person
    }

    // ...
});

如果您打算向刚刚持久化的 person 对象添加断言，请不要使用 TransactionCallbackWithoutResult 回调实现.

instead of the TransactionCallbackWithoutResult callback impl if you plan to add assertions to the person object that was just persisted.
