测试弹簧mvc休息控制器

Question

我正在尝试使用MockMvcBuilders.standaloneSetup方法为spring mvc rest控制器创建一个非常基本的单元测试.我一直收到404错误.下面我列出我的测试应用程序上下文,我的测试类,我的控制器和完整的堆栈跟踪.任何指导表示赞赏.

@Configuration
public class TestContext
{
    @Bean
    public Service service()
    {
        return mock(Service.class);
    }
}

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes={TestContext.class})
@WebAppConfiguration
public class TestUsingWebAppContextSetUp
{
    private MockMvc mockMvc;

    @Autowired
    private Service service;

    @Before
    public void setUp()
    {
        mockMvc = MockMvcBuilders.standaloneSetup(MyController.class)
                .build();
    }

    @Test
    public void test() throws Exception
    {
        mockMvc.perform(get("/search?phoneNumber=5551112222"))
            .andExpect(status().isOk())
            .andExpect(content().contentType(MediaType.APPLICATION_JSON_VALUE));
    }
}

public class MyController
{
    @Autowired
    private Service service;

    @RequestMapping("/search")
    public List<SearchResult> search(@RequestParam(value="phoneNumber") String phoneNumber)
    {
        System.out.println("search called");
        Search search = new Search();
        search.setPhoneNumber(phoneNumber);
        return service.search(search);
    }
}

的javadoc的MockMvcBuilders.standaloneSetup状态

建立一个MockMvc通过注册一个或多个@Controller的情况下,并以编程配置Spring MVC架构.这允许完全控制控制器的实例化和初始化及其依赖性,类似于普通单元测试,同时还可以一次测试一个控制器.

所以你会用它作为

mockMvc = MockMvcBuilders.standaloneSetup(new MyController()).build();

注册一个实际的实例.如果你需要这个是一个Spring托管实例(你可能会考虑它有一个@Autowired字段),你必须从它得到它ApplicationContext.
