java - Spring JUnit 测试

Question

我喜欢测试我的弹簧代码：

@ContextConfiguration(locations = { "/applicationContext.xml" })
@Transactional()
public class Test {

    @Autowired
    MyDao dao;

    @org.junit.Test
    @Rollback(false)
    public void testSomething() throws Exception {
        MyEntity e = new MyEntity();
        dao.create(e);
    }
}

用 eclipse 运行这个测试（作为一个 JUNIT 测试）只会给出一个 Nullpointer-Exception。

我做错了什么？谢谢！

Answer 1

只需添加@RunWith(SpringJUnit4ClassRunner.class)到您的课程中：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/applicationContext.xml" })
@Transactional()
public class Test {

    @Autowired
    MyDao dao;

    @org.junit.Test
    @Rollback(false)
    public void testSomething() throws Exception {
        MyEntity e = new MyEntity();
        dao.create(e);
    }
}

你需要spring-test那个。

您可以像这样添加事务测试基类

@ContextConfiguration(locations = "classpath*:applicationContext.xml")
public class IntegrateTestBase extends AbstractTransactionalJUnit4SpringContextTests {
}

然后写你的测试类

public class Test extends IntegrateTestBase {

    @Autowired
    MyDao dao;

    @org.junit.Test
    @Rollback(false)
    public void testSomething() throws Exception {
        MyEntity e = new MyEntity();
        dao.create(e);
    }
}

您无需在每个测试类中编写@ContextConfigurationand@Transcational
