title: Testing a spring mvc rest controller
body: <p>I'm trying to create a very basic unit test for a spring mvc rest controller using the MockMvcBuilders.standaloneSetup method. I keep getting a 404 error. Below I list my Test application context, my test class, and my controller and the full stack trace. Any guidance is appreciated.</p>
  
  <pre><code>@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&lt;SearchResult&gt; search(@RequestParam(value="phoneNumber") String phoneNumber)
      {
          System.out.println("search called");
          Search search = new Search();
          search.setPhoneNumber(phoneNumber);
          return service.search(search);
      }
  }
  </code></pre>
