Spring mvc 如何测试POST-spring mvc

我的问题是怎么称呼这个。我可以

MyObject o = new MyObject();
myController.save(o, "value");

但这不是我想做的。我希望MyObject位于请求后正文中？如何做到这一点

@Requestmapping(value="/save/{value}", method=RequestMethod.POST)
public void post(@Valid MyObject o, @PathVariable String value{
    objectService.save(o);
}

我要说的是单元测试

您需要使用RequestBody：

@Requestmapping(value="/save/{value}", method=RequestMethod.POST)
public void post(@RequestBody MyObject o, @PathVariable String value{
   objectService.save(o);
}

有关请求正文文档的一般信息：

请参阅下面的示例代码，该代码演示了如何使用junit和spring测试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) 
            {

            } 
    }
}

好啊也许…但是假装我在用它。我如何进行单元测试？非常感谢。一定是json吗？我必须使用requestbody吗？它可以转换为控制器接受的任何类型。形成数据，获取字节并将其设置为请求。这样我就可以执行request.setContent（o）？您需要将o转换为控制器接受的消息类型之一。控制器接受的消息类型是什么？与JSON/XML类似？如果您试图接受模型属性，则需要修改控制器，如（@modeldattribute（“myobject”）myobject o、@PathVariable String value），然后在单元测试中可以将myobject设置为参数，如request.setAttribute（“myobject”，o）。

@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) 
            {

            } 
    }
}
