list转map 键值对

Map<Long,Account> map = new HashMap<Long,Account>();

for(int i=0;i<list.size();i++){

  Account account = (Account)list.get(i);

  map.put(account.getId(),account);

}

后台的

package com.iport.site.controller;

import com.iport.base.basecontroller.BaseController;

import com.iport.exception.SystemException;

import com.iport.site.model.SiteSettingEntity;

import com.iport.site.service.SiteSettingService;

import com.iport.util.*;

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

import org.springframework.context.annotation.Scope;

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

import org.springframework.web.bind.annotation.RequestMapping;

import java.util.*;

@Controller

@Scope("prototype")

@RequestMapping("/site/")

public class SiteSettingController extends BaseController {

    @Autowired

    private SiteSettingService siteSettingService;

    @RequestMapping("listUI.html")

    public String listUI(Model model) {

        System.out.println("111111111111111111");

        try {

            List<SiteSettingEntity> list = siteSettingService.querySiteSettingList();

            Map<String, String> map = new HashMap<String, String>();

            for (int i = 0; i < list.size(); i++) {

                SiteSettingEntity siteSettingEntity = list.get(i);

                map.put(siteSettingEntity.getKey(), siteSettingEntity.getValue());

            }

　　　　　　　　

            model.addAttribute("map", map);

            //System.out.println("map================" + map.get("SiteName").toString());

            return Common.BACKGROUND_PATH + "/site/list";

        } catch (Exception e) {

            throw new SystemException(e);

        }

    }

}

取值的话就是页面中

${map.key}  或者${map['key']}来显示值
