java - 带有json的Spring rest junit帖子

Question

我正在尝试与项目一起为 spring rest web 服务创建 junit 测试。这适用于 get 方法，但它确实适用于 post json 作为输入。这是带有get方法的代码。如果有人在 json junit 测试后帮助休息，我们将不胜感激。

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(locations=("/spring/application-config.xml"))
public class LoginServiceFacadeTestImpl extends AbstractTest {

    @Autowired
    private WebApplicationContext wac;

    private MockMvc mockMvc;

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


    @Test
    public void testSearchProductByNameFound() throws Exception {
        String keyword = "";
        this.mockMvc.perform(get("/perlogin")
            .param("q", keyword)
            .accept(MediaType.APPLICATION_JSON))
            .andExpect(status().isOk())
            .andExpect(content().contentType(MediaType.APPLICATION_JSON))
            .andExpect(jsonPath("$.name").value(keyword));
    }
}

但是我得到如下错误

这是我的 Controller 类

package com.backend.controller;

@Controller
@RequestMapping("/")
public class JSONController {

    @Autowired
    private SessionManager sessionManager;

    public JSONController() {
    }   

    @RequestMapping(value = "/perlogin", method = RequestMethod.POST)
    public @ResponseBody
    ValDataVo preLogin(HttpServletRequest httpServletRequest,
            HttpServletResponse httpServletResponse) {
        addDefaultResponseHeaders(httpServletResponse);     
        sessionManager.setHttpSession(httpServletRequest.getSession());
        logger.info("***login session*****::"+httpServletRequest.getSession().getId());

        return resultData;
    }
}

这是我的调度程序 servlet

Answer 1

假设

@ContextConfiguration(locations=("/spring/application-config.xml"))

指的是您显示的 XML 配置，没有注册 @Controller beans，因此没有任何东西可以处理任何请求。

您的@ContextConfiguration 应该加载dispatcher-servlet.xml 文件，该文件由DispatcherServlet 使用。该上下文配置文件应包含

<mvc:annotation-driven /> 

将找到的任何 @Controller bean 注册为处理程序。
