Question

美好的一天。

为我的Spring应用程序编写JUnit测试可以解决下一个问题。我的标准上下文配置文件存储在/ webapp中的项目中（不是单元测试的类路径的一部分）。

JUnit测试：

    @RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"file:src/main/webapp/WEB-INF/config/application-context.xml", "file:src/main/webapp/WEB-INF/config/mvc-config.xml"})
public class AdvertORMServiceTest {

    @Autowired
    private AdvertORMService jpaAdvertORMService;

    @Test
    public void queryAllAdvertsTest() {
        List<Advert> adverts = jpaAdvertORMService.findAll();
        Assert.assertNotNull(adverts);
    }

}

应用context.xml中：

看起来应用程序上下文已正确加载，但您必须指示测试类使用Web配置：

@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(
        locations = {"file:src/main/webapp/WEB-INF/config/mvc-config.xml", 
                "file:src/main/webapp/WEB-INF/config/application-context.xml"})
public class AdvertORMServiceTest {

JUnit的@ContextConfiguration（来自/ webapp的配置）
