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){
		scheduleService.deleteschedule(id);
		return "redirect:selectAll.action";
	}
	@RequestMapping("/insertschedule")
	public String insertschedule(Schedule schedule,Model model){
		scheduleService.insertschedule(schedule);

		return "redirect:selectAll.action";

	}
	@RequestMapping("/updateschedule")
	public String updateschedule(Schedule schedule,Model model){
		scheduleService.updateschedule(schedule);
		model.addAttribute("error", "更新成功");
		model.addAttribute("schedule", schedule);
		model.addAttribute("mainPage", "updateschedule.jsp");
		return "admin/main1";

	}
	@RequestMapping("/toinsert")
	public String toinsert(Model model){
		model.addAttribute("mainPage", "addschedule.jsp");

		return "admin/main1";

	}
	@RequestMapping("/toupdate")
	public String toupdate(Model model,Integer id){
		Schedule schedule=scheduleService.selectbyid(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){

		 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","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{
			model.addAttribute("error","添加成功");
			houselistService.inserthouse(houselist);
			model.addAttribute("houselist",houselist);
			model.addAttribute("mainPage","addhouse.jsp");
		return "admin/main1";
	}
		}

	@RequestMapping("/toaddhouse")
	public String toaddhoust(Model model){
		model.addAttribute("mainPage","addhouse.jsp");

		return "admin/main1";
	}
	@RequestMapping("/deletehouse")
	public String deletehouse(Integer id){
		houselistService.deletehouse(id);

		return "redirect:ahouselist.action";
	}
	@RequestMapping("/toahouselist")
	public String toahouselist(){

		return "ahouselist.action";
	}
	@RequestMapping("/findid")
	public String findid(Integer id,Model model){
		Houselist list=houselistService.findid(id);
		model.addAttribute("houselist",list);
		model.addAttribute("mainPage", "changehouse.jsp");
		return "admin/main1";
	}
	@RequestMapping("/findhouseidupdate")
	public String findhouseidupdate(Houselist houselist,Model model){
		Houselist list=houselistService.findhouseidupdate(houselist);
		if(list!=null){
			model.addAttribute("houselist",houselist);
			model.addAttribute("mainPage", "changehouse.jsp");
			model.addAttribute("error","该房屋id已存在");
			return "admin/main1";
		}
		else{
			houselistService.updatehouse(houselist);
			model.addAttribute("houselist",houselist);
			model.addAttribute("mainPage", "changehouse.jsp");
			model.addAttribute("error","更新成功");
			return "admin/main1";
		}
	}

}

	public String inserthetong(Model model,Hetong hetong){
		//新增合同信息
		hetongService.inserthetong(hetong);
		Hetong hetong1=hetongService.findhetong(hetong.getHouse_id());
		//修改房屋列表状态
		Houselist houselist=houselistService.findhouseid(hetong1.getHouse_id());
		houselist.setStatus("已租赁");
		houselistService.updatehousestatus(houselist);
		//添加到租赁列表当中
		Zulist zulist=new Zulist();
		Apply apply=applyService.findbyhouse_id(hetong.getHouse_id());
		zulist.setHouse_id(hetong.getHouse_id());
		zulist.setUserlist_id(apply.getUserlist_id());
		zulist.setContract_id(hetong1.getId());
		zulist.setPrice(apply.getPrice());
		zulist.setAddress(apply.getAddress());
		zulistService.insertzulist(zulist);
		//从申请列表中删除
		applyService.deletebyhouse_id(hetong1.getHouse_id());
		model.addAttribute("error", "zusuccess");
		return "redirect:/zulist/findzulist.action";

	}
	@RequestMapping("/seehetong")
	public String seehetong(String house_id,Model model){
		Hetong hetong=hetongService.findhetong(house_id);
		model.addAttribute("hetong", hetong);
		model.addAttribute("mainPage", "hetong.jsp");
		return "admin/main1";
	}
	@RequestMapping("/updatehetong")
	public String updatehetong(String house_id,Model model){
		Hetong hetong=hetongService.findhetong(house_id);
		model.addAttribute("hetong", hetong);
		model.addAttribute("mainPage", "updatehetong.jsp");
		return "admin/main1";
	}
	@RequestMapping("/changehetong")
	public String changehetong(Hetong hetong){
		hetongService.updatehetong(hetong);

		return "redirect:/zulist/findzulist.action";
	}
	//终止合同操作：删除合同，插入已退租列表，删除在租列表，删除房屋列表

	@RequestMapping("/deletehetong")
	public String deletehetong(String house_id,Model model){
		hetongService.deletehetong(house_id);
		Zulist zulist=zulistService.findzulist(house_id);
		Checkout checkout=new Checkout();
		checkout.setHouse_id(house_id);
		checkout.setAddress(zulist.getAddress());
		checkout.setStatus("已退租");
		checkout.setUserlist_id(zulist.getUserlist_id());
		checkoutService.insertcheckout(checkout);
		houselistService.deletehousebyhouseid(house_id);
		zulistService.deletezulist(house_id);

		model.addAttribute("error", "checkoutsuccess");
		return "redirect:/zulist/findzulist.action";
	}

	@RequestMapping("/zukeseehetong")
	public String zukeseehetong(String house_id,Model model){
		Hetong hetong=hetongService.findhetong(house_id);
		model.addAttribute("hetong", hetong);
		model.addAttribute("mainPage", "showhetong.jsp");
		return "zuke/main";

}
