java - Spring MVC 单元测试 - 我可以将 URL(带参数)传递给 Controller ​​吗？

Question

我将对 Spring MVC Controller (或整个站点，如果可能)进行单元测试。

我想传递一个 URL(作为字符串)，例如"/metrics/filter?a1=1&a2=2&a3=abcdefg&wrongParam=WRONG"并检查将返回什么 Controller 。

有什么简单的方法吗？

例子:

 @RequestMapping(value = {"/filter"}, method = RequestMethod.GET)
    @ResponseBody
    public List<MetricType> getMetricTypes(
             @RequestParam(value = "subject", required = false) Long subjectId
            ,@RequestParam(value = "area", required = false) Long areaId
            ,@RequestParam(value = "onlyImmediateChildren", required = false) Boolean onlyImmediateChildren

            ,@RequestParam(value = "componentGroup", required = false) Long componentGroupId

            ,@RequestParam(value = "hasComponentGroups", required = false) Boolean hasComponentGroups
                                            ) throws Exception
    {
          //some code
    }

非常感谢

更新

• 我只使用 GET，不使用 post
• 我不使用模型对象(见上面的例子)
• 我的系统是一个网络服务，它有很多“/someEntity/filter?a1=123&a2=1234&a3=etc”方法和各种参数组合。我不确定在这种情况下使用模型对象是否可行。

@RunWith( SpringJUnit4ClassRunner.class)
@ContextConfiguration("file:WebRoot/WEB-INF/path/to/your-context.xml") 
public class YourControllerTest {

    private MockHttpServletRequest request;
    private MockHttpServletResponse response;
    private AnnotationMethodHandlerAdapter adapter;


@Before
public void setUp(){
    this.request = new MockHttpServletRequest();
    this.response = new MockHttpServletResponse();
    this.adapter = new AnnotationMethodHandlerAdapter();
}


    @Test
    public void getMetricTypes() throws Exception{



        request.setRequestURI("/filter");
        request.setMethod("GET");
        request.setParameter("subject", "subject");
        request.setParameter("area", "area");    
        request.setParameter("onlyImmediateChildren", "onlyImmediateChildren");    
        request.setParameter("componentGroup", "componentGroup");    
        request.setParameter("hasComponentGroups", "hasComponentGroups");    

        ModelAndView mav = adapter.handle(request, response, yourController);
        Assert.assertEquals(200, response.getStatus());
        //Assert what you want
    }
}
