报错信息

报错信息

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.reflect.UndeclaredThrowableException

在给controller加功能时，方法参数用了HttpServletRequest和HttpServletResponse， 在LogAop切面类中获取方法的映射出错，就报了500错误。
原代码

package com.oracle.controller;

import com.oracle.pojo.Product;
import com.oracle.service.ProductService;
import com.oracle.utils.Pager;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

import javax.annotation.security.RolesAllowed;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.List;

@Controller
@RequestMapping("/product")
public class ProductController {

    @Autowired
    ProductService productService;

    @RequestMapping("/findProduct")
    @RolesAllowed("ROLE_ADMIN")
    public String findProduct(@RequestParam(value = "pageNo", required = false, defaultValue = "1") Integer pageNo,
                                    @RequestParam(value = "pageSize", required = false, defaultValue = "2") Integer pageSize,
                                    HttpServletRequest request, HttpServletResponse response){
        //ModelAndView mv = new ModelAndView();

        Pager<Product> pager = productService.findAllByCondition(pageNo, pageSize);
        List<Product> list = pager.getList();
        for (Product product : list) {
            System.out.println(product + "==");
        }

        request.getSession().setAttribute("pager",pager);

        return ("/pages/product-list");
    }

}

用ModelAndView来存对象和设置转发的页面即可，就不用HttpServletRequest和HttpServletResponse。
修改后

package com.oracle.controller;

import com.oracle.service.ProductService;
import com.oracle.utils.Pager;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

import javax.annotation.security.RolesAllowed;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.List;

@Controller
@RequestMapping("/product")
public class ProductController {

    @Autowired
    ProductService productService;


    @RequestMapping("/findProduct")
    @RolesAllowed("ROLE_ADMIN")
    public ModelAndView findProduct(@RequestParam(value = "pageNo", required = false, defaultValue = "1") Integer pageNo,
                                    @RequestParam(value = "pageSize", required = false, defaultValue = "2") Integer pageSize){
        ModelAndView mv = new ModelAndView();

        Pager<Product> pager = productService.findAllByCondition(pageNo, pageSize);
        List<Product> list = pager.getList();
        for (Product product : list) {
            System.out.println(product + "==");
        }

        mv.addObject("pager",pager);
        mv.setViewName("/pages/product-list");
        return mv;
    }
}
