這篇文章主要介紹Java怎么實現財務預算管理系統,文中介紹的非常詳細,具有一定的參考價值,感興趣的小伙伴們一定要看完!
功能包括:實現公司對項目的管理。
Jdk1.8 + Tomcat8.5 + mysql + Eclispe(IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持)
JSP +Spring + SpringMVC + MyBatis + html+ css + JavaScript + JQuery + Ajax + layui+ maven等等
用戶信息控制層:

數據圖形展示:
@RestController @RequestMapping("/bills") public class BillController { @Resource private BillService billService; /** * 適用于統計圖 * @param bill * @return */ @RequestMapping("/getBillsToChart") public Result<Bill> findByWhereNoPage(Bill bill, HttpSession session){ bill = getHouseBill(bill,session); return billService.findByWhereNoPage(bill); } @RequestMapping("/getBillsByWhere/{type}/{pageNo}/{pageSize}") public Result<Bill> getBillsByWhere(Bill bill,@PathVariable String type, @PathVariable int pageNo, @PathVariable int pageSize, HttpSession session){ if("-1".equals(bill.getPayway())){ bill.setPayway(null); } bill.setType(type); bill = getHouseBill(bill,session); System.out.println(bill); PageModel model = new PageModel<>(pageNo,bill); model.setPageSize(pageSize); return billService.findByWhere(model); } @RequestMapping("/getBillsByUserid/{userid}/{pageNo}/{pageSize}/{year}/{month}") public Result getBillsByUserid(@PathVariable Integer userid, @PathVariable int pageNo, @PathVariable int pageSize, @PathVariable int year, @PathVariable int month){ Bill bill = new Bill(); bill.setUserid(userid); SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd"); bill.setStartTime(year+"-0"+month+"-01"); try { Date date = sdf.parse(year+"-0"+(month+1)+"-01"); date.setDate(date.getDate()-1); bill.setEndTime(sdf.format(date)); } catch (ParseException e) { e.printStackTrace(); } PageModel model = new PageModel<>(pageNo,bill); model.setPageSize(pageSize); Result result = billService.findByWhere(model); List<Map<String,String>> r = billService.getMonthlyInfo(model); Map<String,String> map = new HashMap<>(); for (Map<String,String> m: r) { map.put(m.get("typeid"),String.format("%.2f",m.get("sum(money)"))); } result.setData(map); return result; } private Bill getHouseBill(Bill bill, HttpSession session) { UserInfo currentUser = Config.getSessionUser(session); //當登錄用戶為家主時,查詢默認查詢全家賬單情況 //當登錄用戶為普通用戶時,僅查詢當前用戶的賬單 if (currentUser.getRoleid() == 2){ bill.setHouseid(currentUser.getHouseid()); }else if (currentUser.getRoleid() == 3){ bill.setUserid(currentUser.getId()); } return bill; } @RequestMapping(value = "/addBill",method = RequestMethod.POST) public Result add(Bill bill, HttpSession session){ if (Config.getSessionUser(session)!=null){ bill.setUserid(Config.getSessionUser(session).getId()); } Utils.log(bill.toString()); try { int num = billService.add(bill); if(num>0){ int billid = bill.getId(); bill = new Bill(); bill.setId(billid); return ResultUtil.success("記賬成功!",billService.findByWhereNoPage(bill)); // return ResultUtil.success("記賬成功!",bill); }else { return ResultUtil.unSuccess(); } }catch (Exception e){ return ResultUtil.error(e); } } @RequestMapping("/updateBill") public Result update(Bill bill, HttpSession session){ if (Config.getSessionUser(session)!=null){ bill.setUserid(Config.getSessionUser(session).getId()); } Utils.log(bill.toString()); try { int num = billService.update(bill); if(num>0){ return ResultUtil.success("修改成功!",null); }else { return ResultUtil.unSuccess(); } }catch (Exception e){ return ResultUtil.error(e); } } @RequestMapping("/delBill") public Result del(int id){ try { int num = billService.del(id); if(num>0){ return ResultUtil.success("刪除成功!",null); }else { return ResultUtil.unSuccess(); } }catch (Exception e){ return ResultUtil.error(e); } } @RequestMapping("/getPayways") public Result<Payway> getAllPayways(){ try { List<Payway> payways = billService.getAllPayways(); if (payways!=null && payways.size()>0){ return ResultUtil.success(payways); }else { return ResultUtil.unSuccess(); } } catch (Exception e) { return ResultUtil.error(e); } } }
用戶信息mapper類:
@Repository public interface UserInfoMapper { /** * 獲取單個用戶信息,可用于: * 1.登錄 * 2.通過用戶某一部分信息獲取用戶完整信息 * @param userInfo * @return */ UserInfo getUserInfo(UserInfo userInfo); /** * 注冊 * @param userInfo * @return */ int addUser(UserInfo userInfo); /** * 通過username判斷該用戶是否存在 * @param userInfo * @return */ int userIsExisted(UserInfo userInfo); /** * 通過條件獲取符合條件的優化信息 -- 分頁 * @param model * @return */ List<UserInfo> getUsersByWhere(PageModel<UserInfo> model); int getToatlByWhere(PageModel<UserInfo> model); int add(UserInfo userInfo); int update(UserInfo userInfo); int delete(String id); List<Role> getAllRoles(); int addRole(Role role); int updateRole(Role role); int deleteRole(String id); Role getRoleById(String id); int addHouseId(House house); }
