Spring整合Junit4进行单元测试

@RunWith(SpringJUnit4ClassRunner.class)
//值是String数组，可以写多个xml配置文件
@ContextConfiguration(locations = {"classpath:spring-config.xml"})
public class Test {
    @Autowired
    private User user;

    @org.junit.Test
    public void test1(){
        System.out.println(user);
    }
    
    @org.junit.Test
    public void test2(){
        System.out.println(user);
    }
    
    @org.junit.Test
    public void test3(){
        System.out.println(user);
    }
}

    @Before
    public void before(){
        System.out.println("before");
    }

    @After
    public void after(){
        System.out.println("after");
    }
