Spring RestController + Junit 测试

Question

我正在玩 spring-测试 spring 框架。我的目的是在我的休息控制器中测试以下 POST 方法：

@RestController
@RequestMapping("/project")
public class ProjectController {

  @RequestMapping(method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
  public Project createProject(@RequestBody Project project, HttpServletResponse response) {
    // TODO: create the object, store it in db...
    response.setStatus(HttpServletResponse.SC_CREATED);
    // return the created object - simulate by returning the request.
    return project;
  }
}

这是我的测试用例：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {ProjectController.class })
@WebAppConfiguration
public class ProjectControllerTest {

    private MockMvc mockMvc;

    @Autowired
    private WebApplicationContext wac;

    @Before
    public void setUp() {
        mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
    }

    @Test
    public void testCreationOfANewProjectSucceeds() throws Exception {
        Project project = new Project();
        project.setName("MyName");
        String json = new Gson().toJson(project);

        mockMvc.perform(
                post("/project")
                        .accept(MediaType.APPLICATION_JSON)
                        .contentType(MediaType.APPLICATION_JSON)
                        .content(json))
                .andExpect(status().isCreated());
    }

}

当我执行它时，我得到状态代码 415 而不是 201。我错过了什么？一个简单的 GET 请求就可以了。

您需要添加注释 @EnableWebMvc 才能使 @RestController 正常工作，您的代码中缺少此注释，添加此注释将解决问题
