替换import org.springframework.test.context.transaction.TransactionConfiguration; 在Spring Test 4.3.1版本中？

Question

我正在研究这个JPA QueryDSL例子.在这个例子中我创建了PersonDaoTest.java.早些时候我使用较低版本的spring-test客户端要求更新它的最新版本,所以我使用4.3.1.RELEASE.当我使用这个版本时,我看到它import org.springframework.test.context.transaction.TransactionConfiguration;是@deprecated.有谁能告诉我import org.springframework.test.context.transaction.TransactionConfiguration;最新版本的更换？

PersonDaoTest.java

@ContextConfiguration("/test-context.xml")
@RunWith(SpringJUnit4ClassRunner.class)
@Transactional
@TransactionConfiguration(defaultRollback = true)
public class PersonDaoTest {

    @Autowired
    private PersonDao personDao;

    //

    @Test
    public void testCreation() {
        personDao.save(new Person("Erich", "Gamma"));
        final Person person = new Person("Kent", "Beck");
        personDao.save(person);
        personDao.save(new Person("Ralph", "Johnson"));

        final Person personFromDb = personDao.findPersonsByFirstnameQueryDSL("Kent").get(0);
        Assert.assertEquals(person.getId(), personFromDb.getId());
    }

    @Test
    public void testMultipleFilter() {
        personDao.save(new Person("Erich", "Gamma"));
        final Person person = personDao.save(new Person("Ralph", "Beck"));
        final Person person2 = personDao.save(new Person("Ralph", "Johnson"));

        final Person personFromDb = personDao.findPersonsByFirstnameAndSurnameQueryDSL("Ralph", "Johnson").get(0);
        Assert.assertNotSame(person.getId(), personFromDb.getId());
        Assert.assertEquals(person2.getId(), personFromDb.getId());
    }

    @Test
    public void testOrdering() {
        final Person person = personDao.save(new Person("Kent", "Gamma"));
        personDao.save(new Person("Ralph", "Johnson"));
        final Person person2 = personDao.save(new Person("Kent", "Zivago"));

        final Person personFromDb = personDao.findPersonsByFirstnameInDescendingOrderQueryDSL("Kent").get(0);
        Assert.assertNotSame(person.getId(), personFromDb.getId());
        Assert.assertEquals(person2.getId(), personFromDb.getId());
    }

    @Test
    public void testMaxAge() {
        personDao.save(new Person("Kent", "Gamma", 20));
        personDao.save(new Person("Ralph", "Johnson", 35));
        personDao.save(new Person("Kent", "Zivago", 30));

        final int maxAge = personDao.findMaxAge();
        Assert.assertTrue(maxAge == 35);
    }

    @Test
    public void testMaxAgeByName() {
        personDao.save(new Person("Kent", "Gamma", 20));
        personDao.save(new Person("Ralph", "Johnson", 35));
        personDao.save(new Person("Kent", "Zivago", 30));

        final Map<String, Integer> maxAge = personDao.findMaxAgeByName();
        Assert.assertTrue(maxAge.size() == 2);
        Assert.assertSame(35, maxAge.get("Ralph"));
        Assert.assertSame(30, maxAge.get("Kent"));
    }
}

文档存在的原因是:作为开发人员,您应该阅读它!

@TransactionConfiguration的Javadoc明确指出:

已过时.

从Spring Framework 4.2开始,使用@Rollback或@Commit在类级别和transactionManager限定符中@Transactional.

因此,你的问题的答案很简单@Rollback.

但是......更重要的是,你的声明@TransactionConfiguration(defaultRollback=true)是无用的,因为true无论如何都是默认的.所以你可以完全删除它.
