请参阅下面的示例代码，该示例代码演示如何使用junit和spring-test对控制器进行单元测试。
@RunWith(SpringJUnit4ClassRunner.class)@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class, DirtiesContextTestExecutionListener.class, TransactionalTestExecutionListener.class })@Transactional@ContextConfiguration(locations = { "classpath:rest.xml" })public class ControllerTest{ private MockHttpServletRequest request; private MockHttpServletResponse response; @Autowired private RequestMappingHandlerAdapter handlerAdapter; @Autowired private RequestMappingHandlerMapping handlerMapping; @Before public void setUp() throws Exception { this.request = new MockHttpServletRequest(); request.setContentType("application/json"); this.response = new MockHttpServletResponse(); } @Test public void testPost(){ request.setMethod("POST"); request.setRequestURI("/save/test"); //replace test with any value final ModelAndView mav; Object handler; try{ MyObject o = new MyObject(); //set values //Assuming the controller consumes json ObjectMapper mapper = new ObjectMapper(); //set o converted as JSON to the request body //request.setContent(mapper.writevalueAsString(o).getBytes()); request.setAttribute("attribute_name", o); //in case you are trying to set a model attribute. handler = handlerMapping.getHandler(request).getHandler(); mav = handlerAdapter.handle(request, response, handler); Assert.assertEquals(200, response.getStatus()); //Assert other conditions. } catch (Exception e) { } }}
