title: Failed to load ApplicationContext for JUnit test of Spring controller
body: <p>I want to write a test case to check my controller (getPersons). This is a server side code. I have confusion what should i put inside <code>@ContextConfiguration(locations={"file:src/main/webapp/WEB-INF/app-contest.xml"})</code></p>
  
  <p>Secondly, I'm getting some errors like this:</p>
  
  <blockquote>
    <p>Failed to load application context. Can not find the path [which I specified in @ContextConfiguration]</p>
  </blockquote>
  
  <p>I have a structure like this:</p>
  
  <pre><code> restAPI
      *src/main/java
        com.company.controller
           personController.java
      *Test
        com.company.testController
           personControllerTest.java
      *src
        main
         webapp
           WEBINF
             app-context.xml
  
  
  @Autowired
  private PersonService personService;
  
  @RequestMapping(value="/t2/{yy_id}/person", method=RequestMethod.GET)
  @ResponseBody
  public PersonInfo[] getPersons() {
  
      return personService.getPersons();
  }
  </code></pre>
  
  <hr>
  
  <p>This is my Test</p>
  
  <pre><code>@RunWith(SpringJUnit4ClassRunner.class)
  @ContextConfiguration(locations={"classpath:WEB-INF/app-context.xml"})
  @WebAppConfiguration
  public class PersonControllerTest  {
  
  
  @Autowired
  private WebApplicationContext wac;
  
  private MockMvc mockMvc;
  
  @Before
  public void setup() {
      this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
  }
  
  @Autowired
  private PersonService personService;
  
  @Test
  public void getPersons() throws Exception {
  
      this.mockMvc.perform(get("/t2/1/person")
              .accept(MediaType.APPLICATION_JSON))
              .andExpect(status().isOk());
  
  }
