Spring3.2 Contorller单元测试参数问题： java.lang.NoSuchMethodException

 使用3.2做单元测试的时候发现这个问题，因为之前都是用3.0中的配置适配器使用AnnotationMethodHandlerAdapter，到3.2中升级为RequestMappingHandlerAdapter；

运行之前的单元测试发现报异常：java.lang.NoSuchMethodException，看了一下堆栈发现反射调用的方法签名明显不对，于是看了一下调用的代码，

之前是：handlerAdapter.handle(request, response,  new HandlerMethod(controller, "setClassBreaksInfo"))

感觉是这里的问，继续看handle的参数，发现还有一个Class<?>... parameterTypes，预计根据这里还匹配调用参数签名的，于是改为跟调用方法签名对应的ClassType，然后可以正确运行了，整体配置如下：

 

 1 package com.catt.base;

 2 

 3 import org.junit.runner.RunWith;

 4 import org.springframework.beans.factory.annotation.Autowired;

 5 import org.springframework.mock.web.MockHttpServletRequest;

 6 import org.springframework.mock.web.MockHttpServletResponse;

 7 import org.springframework.test.context.ContextConfiguration;

 8 import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

 9 import org.springframework.test.context.transaction.TransactionConfiguration;

10 import org.springframework.transaction.annotation.Transactional;

11 import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter;

12 

13 

14 @RunWith(SpringJUnit4ClassRunner.class)  

15 @ContextConfiguration(locations = { "classpath:applicationContext.xml" ,"classpath:spring-servlet.xml"})

16 @Transactional

17 @TransactionConfiguration(defaultRollback = true)

26       

27      protected  final MockHttpServletRequest request = new MockHttpServletRequest();  

28      protected  final MockHttpServletResponse response = new MockHttpServletResponse();

29

32      {

34      }

35 }

测试抽象累

import javax.servlet.http.HttpSession;

import com.catt.action.pub.GisAction;

import com.catt.base.AbstractActionTestCase;





public class GisTest extends AbstractActionTestCase{

    @Autowired

    private GisAction controller;

    

    @Test

    public void testSetClassBreaksInfo()

    {

        

         request.setRequestURI("/gisAction/setClassBreaksInfo.do");  

         //request.setMethod(HttpMethod.POST.name()); 

         

         request.addParameter("userid", "5802919");

         request.addParameter("gisSqlId", "1");

         request.addParameter("classBreaksType", "2");

         request.addParameter("breaksInfo", "1|0|1|0xFF0000|高倒流栅格1,2|2|3|0xFF0000|高倒流栅格2");

         

         

         HttpSession session = request.getSession();   

            //设置 认证信息   

         session.setAttribute("1", 1);

         

         ModelAndView mv = null;



         try {

             mv = handlerAdapter.handle(request, response,  new HandlerMethod(controller, "setClassBreaksInfo", 

                     String.class,String.class,String.class,String.class,HttpServletResponse.class)); 

         } catch (Exception e) {

             e.printStackTrace();

         }

         

         assertEquals("/setClassBreaksInfo", mv.getViewName());   

    }

}
