结组作业，第二次冲刺（6）

今天是第二次冲刺的第六天，昨天完成了广告功能，今天我们准备增加聊天功能，能够实现在软件中直接点击对应的兼职信息，就能和其用户聊天，管理员能够对聊天内容进行审核。以下为今日部分代码：

package com.work.controller;

import java.util.List;

import javax.servlet.http.HttpServletResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.work.common.utils.BaseUtil;
import com.work.common.utils.JsonUtil;
import com.work.pojo.Chat;
import com.work.service.ChatService;

@Controller
@RequestMapping(value="/server/chat")
public class ChatController extends BaseUtil{

    @Autowired
    private ChatService chatService;
    
    //去聊天列表
    @RequestMapping("/goChatList")
    public ModelAndView goChatList(ModelAndView mv){
        mv.setViewName("server/chatManage/chatList");
        return mv;
    }
    
    //获取聊天列表
    @RequestMapping("/getChatList")
    public void getChatList(HttpServletResponse response,Chat chat,Integer page,Integer limit){
        if(page == null){
            page = 1;
        }
        if(limit == null){
            limit = 10;
        }
        int totalCount = chatService.getChatListCount(chat);
        List<Chat> list = chatService.getChatList(chat,(page-1) * limit, limit);
        output(response,JsonUtil.buildJsonByTotalCount(list, totalCount));
    }
    
    //去编辑聊天
    @RequestMapping("/goUpdateChat")
    public ModelAndView goUpdateChat(ModelAndView mv,Integer id){
        Chat chat = chatService.getChatById(id);
        mv.addObject("chat", chat);
        mv.setViewName("server/chatManage/updateChat");
        return mv;
    }
    
    //编辑聊天
    @RequestMapping("/updateChat")
    public void updateChat(HttpServletResponse response,Chat chat){
        chatService.updateChat(chat);
        output(response,JsonUtil.buildFalseJson(0, "编辑成功！"));
    }

    //删除聊天
    @RequestMapping("/deleteChat")
    public void deleteChat(HttpServletResponse response,Integer id){
        chatService.deleteChatByChatId(id);
        output(response,JsonUtil.buildFalseJson(0, "删除成功！"));
    }

}
