Java 房屋租赁系统的实现流程

一、项目简述

功能： 房源信息模块：房源信息展示、房源信息更新、房源信息 增加、房源信息删除 账户管理模块：账户登录、账户绑定、账户管理 租金结算模块：每月租金信息、租金交付功能、月租金收 入总^^克计 房屋租赁合同管理模块：房屋租赁合同录入、房屋租赁合 同展示、房屋租赁价格修改、房屋租赁合同终止 报障模块：租客报账、管理员报障审核、租客报b章统计 日程模块：收租日程显示等。

二、项目运行

环境配置： jdk1.8 + tomcat8.5 + mysql + eclispe (intellij idea,eclispe,myeclispe,sts 都支持)

项目技术： jsp +spring + springmvc + mybatis + html+ css + javascript + jquery + ajax + layui+ maven等等。

用户信息控制层：

@controller
 
public class usercontroller {
 
	@autowired
	private userservice userservice;
	
	@requestmapping("/login")
	public string userlist() throws exception{
		
		
		return "login";
		
	}
	@requestmapping("/logincheck")
	public string login(user user,model model,httpsession httpsession) throws exception{
		
		user user1=userservice.login(user);
		
		if(user1!=null){
			httpsession.setattribute("user", user1);
			if(user1.gettype().equals("zuke")){
				return "zuke/main";
			}
			else{
				return "admin/main1";
			}
		}else{
			string error="error";
			model.addattribute("error", error);
		return "login";
		}
	}
	@requestmapping("/toindex")
	public string toindex(model model) throws exception{
		
		
		return "admin/index";
		}
	}
 

日程安排控制器：

@controller
@requestmapping("/schedule")
public class schedulecontroller {
	@autowired
	private scheduleservice scheduleservice;
	
	@requestmapping("/selectall")
	public string selectall(model model ,@requestparam(required=false,defaultvalue="1") integer page,
            @requestparam(required=false,defaultvalue="6") integer pagesize){
		 pagehelper.startpage(page, pagesize);
		list<schedule> schedule=scheduleservice.selectall();
		pageinfo<schedule> p=new pageinfo<schedule>(schedule);
		model.addattribute("schedule", schedule);
		model.addattribute("p", p);
		model.addattribute("mainpage", "schedule.jsp");
		return "admin/main1";
	}
	@requestmapping("/deleteschedule")
	public string deleteschedule(integer id){

		return "redirect:selectall.action";
	}
	@requestmapping("/insertschedule")
	public string insertschedule(schedule schedule,model model){

	}
	@requestmapping("/updateschedule")
	public string updateschedule(schedule schedule,model model){

		model.addattribute("mainpage", "updateschedule.jsp");
		return "admin/main1";
		
	}
	@requestmapping("/toinsert")
	public string toinsert(model model){
		model.addattribute("mainpage", "addschedule.jsp");

	}
	@requestmapping("/toupdate")
	public string toupdate(model model,integer id){

		model.addattribute("schedule", schedule);
		
		model.addattribute("mainpage", "updateschedule.jsp");
		
		return "admin/main1";
		
	}
}

房屋列表信息控制器：

@controller
public class houstlistcontroller {
	@autowired
	private houselistservice houselistservice;
	
	@requestmapping("/houselist")
	public string houselist(model model ,@requestparam(required=false,defaultvalue="1") integer page,
            @requestparam(required=false,defaultvalue="6") integer pagesize){

		list<houselist> houselist=houselistservice.selectall();
	pageinfo<houselist> p=new pageinfo<houselist>(houselist);
		
				
		model.addattribute("p", p);
		model.addattribute("houselist",houselist);
		model.addattribute("mainpage","houselist.jsp");
		return "zuke/main";
	}
	@requestmapping("/ahouselist")
	public string ahouselist(model model ,@requestparam(required=false,defaultvalue="1") integer page,
            @requestparam(required=false,defaultvalue="6") integer pagesize){
		
		 pagehelper.startpage(page, pagesize);
		list<houselist> houselist=houselistservice.selectall();
	pageinfo<houselist> p=new pageinfo<houselist>(houselist);
		
				
		model.addattribute("p", p);
		model.addattribute("houselist",houselist);
		model.addattribute("mainpage","ahouselist.jsp");
		return "admin/main1";
	}
	
	@requestmapping("/addhouse")
	public string addhouse(model model ,houselist houselist){
		
		string houseid=houselist.gethouseid();
		houselist houselist1=houselistservice.findhouseid(houseid);
		if(houselist1!=null){
			model.addattribute("error","该房屋id已存在");
			model.addattribute("houselist",houselist);
			model.addattribute("mainpage","addhouse.jsp");
			return "admin/main1";
		}else{

			houselistservice.inserthouse(houselist);
			model.addattribute("houselist",houselist);
			model.addattribute("mainpage","addhouse.jsp");
		return "admin/main1";
	}
