测试以@ModelAttribute作为参数的弹簧控制器方法

问题描述

我正在尝试使用此方法测试控制器:

I am trying to test a controller with this method:

@RequestMapping(value ="/test")
公共ModelAndView generateRecords(@ModelAttribute("Employee")员工employee){

@RequestMapping(value="/test")
public ModelAndView generateRecords(@ModelAttribute("Employee") Employee employee) {

我想知道如何创建一个单元测试来对此进行测试.目前，我正在使用:

And I would like to know how can I create a unit testing for testing this. At the moment I am using:

MockHttpServletRequest request = new MockHttpServletRequest();
request.setRequestURI("/test");
//request.setMethod("GET");
new AnnotationMethodHandlerAdapter().handle(request,
        new MockHttpServletResponse(), this.controller);

运行此测试结果时，ModelAttribute(Employee)的值为NULL

Running this test result in NULL value for ModelAttribute (Employee)

进行集成测试时，有什么方法可以将modelattribute对象传递给Controller?

Is there any way to pass modelattribute object to Controller when doing integration testing??

谢谢

总结一下:

解决此问题的方法是选择html元素名称，并在MockHttpRequest对象中填充参数值，然后将其传递.

示例:

MockHttpServletRequest httpServletRequest = MockRequestResponseGenerator.mockRequest(getServletInstance().getServletContext(), "POST", "/test", paramters);

//These paramters must be part of the ModelAttribute Object. Make sure, you are using custom property binding in case you have different object.

        httpServletRequest.setParameter("name", "SPRING MVC INTEGRATION TEST
TEMP");
        httpServletRequest.setParameter("id", "1");
        httpServletRequest.setParameter("desc", "SPRING MVC INTEGRATION TEST DESC");


        getServletInstance().service(httpServletRequest, httpServletResponse);

推荐答案

您可以在与模型属性/表单路径匹配的OGNL路径之后，将请求中的值设置为参数.

You can set the values in the request as parameters following the OGNL paths matching the model attribute/form paths.
