我需要使用JQWidgets插件显示一个网格。我在这里使用spring.Below是我的jsp页面 index.jsp的：

我的春季控制器课程是 AccountsController.java：

package com.gerrytan.pizzashop;

import java.util.ArrayList;
import java.util.List;
import java.util.Map;

 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.http.HttpEntity;
 import org.springframework.http.HttpHeaders;
 import org.springframework.http.HttpMethod;
 import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
 import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;



@Controller
@RequestMapping(value="/account")
public class AccountsController {
@Autowired
private AccountService accountService;
@Autowired
private AccountDAO accountDao;

@RequestMapping(value="/list",method = RequestMethod.GET,produces="application/json")
@ResponseBody
public ModelMap getAccounts(ModelMap model) {
    model.addAttribute("all_item_issue_headers", accountDao.getAccounts());
    System.out.println(model);
    return model;
}

 }

我在控制台获得了模型对象的值：

{all_item_issue_headers=[com.gerrytan.pizzashop.Accounts@a8127, com.gerrytan.pizzashop.Accounts@1a562f5, com.gerrytan.pizzashop.Accounts@103f2db, com.gerrytan.pizzashop.Accounts@3d12a4, com.gerrytan.pizzashop.Accounts@192e8cd, com.gerrytan.pizzashop.Accounts@1f21dcd, com.gerrytan.pizzashop.Accounts@829f8d, com.gerrytan.pizzashop.Accounts@1b922de, com.gerrytan.pizzashop.Accounts@1a03652, com.gerrytan.pizzashop.Accounts@14e7bc5, com.gerrytan.pizzashop.Accounts@19fea29]}

我的问题是我没有显示网格。只显示网格结构。我的代码中有什么问题吗？

使用以下代码解决您的问题

@RequestMapping(value="/list",method = RequestMethod.GET,produces="application/json")
@ResponseBody
public String getAccounts() {
try {
    SimpleDateFormat from = new SimpleDateFormat("dd/MM/yyyy");
    SimpleDateFormat to = new SimpleDateFormat("yyyy-MM-dd");
    List <Accounts> list= accountDao.getAccounts();
    JSONArray cellarray = new JSONArray();
    JSONObject cellobj = null;
    for(Accounts accounts:list){
    cellobj = new JSONObject();
    cellobj.put("id", accounts.getId());
    cellobj.put("periodname",accounts.getPeriodname());
    cellobj.put("startdate", from.format(accounts.getStartdate()));
    cellobj.put("enddate",from.format(accounts.getEnddate()));
    cellobj.put("isactive", accounts.getIsactive());
   cellarray.add(cellobj);

}
return cellarray.toString();
}catch(Exception exception){
    System.out.println("error is "+exception);
    return null;
}
}

网格不显示弹簧控制器响应
