Spring整合JUnit4测试

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:spring/applicationContext-dao.xml",
        "classpath:spring/applicationContext-service.xml","classpath:spring/applicationContext-trans.xml"})
public class SpringJunitTest {
　　　　//Spring运行器+Spring配置文件，我们就得到了Spring容器，容器拿到了，里面的东西(bean等)就拿到了
}

需要做单元测试时继承这个类

public class TestTestTb extends SpringJunitTest {
 
    @Autowired
    private TestTbService testTbService;
 
    @Test
    public void testAdd() throws Exception{
        TestTb testTb = new TestTb();
        testTb.setName("zhangsan");
        testTbService.addTestTb(testTb);
 
    }
}

提高了扩展性

注意，有多个配置文件时用{}

@ContextConfiguration(locations = {"classpath:spring/applicationContext-dao.xml",
        "classpath:spring/applicationContext-service.xml","classpath:spring/applicationContext-trans.xml"})
