Spring rest junit post with json

Question

I am trying to working with project to create junit test for the spring rest webservice. This work fine with the get method but it did works with the post json as input. Here is the code with get method. if anyone help with rest post json junit testing it will appreciated.

@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));
    }
}

But I am getting the error as follows

Here is my controller class

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;
    }
}

Here is my dispatcher servlet

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
       xmlns:context="http://www.springframework.org/schema/context"  xmlns:p="http://www.springframework.org/schema/p" 
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
                            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
                            http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"
       default-autowire="byName">

    <mvc:annotation-driven/>     
    <context:component-scan base-package="com.backend.controller" />

</beans>

Answer 1

Assuming

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

refers to the XML configuration you've shown, there are no @Controller beans registered and therefore nothing to handle any requests.

Your @ContextConfiguration should probably be loading the dispatcher-servlet.xml file which is used by the DispatcherServlet. That context configuration file should contain

<mvc:annotation-driven /> 

to register any found @Controller beans as handlers.
