1、Action层public ActionForward getProjectPayMoneyJsonByPayType(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)throws Exception JiLiangZhiFuService jiLiangZhiFuService = this.getServiceLocator().getJiLiangZhiFuService();int year = Integer.parseInt(request。

2、.getParameter(year);String data = jiLiangZhiFuService.getProjectPayMoneyJsonByPayType(year);response.setContentType(text/xml);response.getWriter().write(data);response.getWriter().flush();response.getWriter().close();return null;Service层public String getProjectPayMoneyJsonByPayType(int year)double a。

3、llTotal = 0;Map map = jiLiangZhiFuDao.getProjectPayMoneyByPayType(year);List dataItemList = SessionBean.getServiceLocator().getDataItemService().getAllDataItemByTypeId(payType);Map map\_ep = new HashMap();map\_ep.put(account\_id, 2);map\_ep.put(isSelectTwoStageProject, true);List engineeringPhaseList = 。

8、eyByPayType(final int year) try return (Map)this.getHibernateTemplate().execute(new HibernateCallback()public Object doInHibernate(Session session) throws HibernateException, SQLException Connection con = session.connection();Statement stmt = con.createStatement();CallableStatement cs = con.prepareC。

9、all(call proc\_records(?);cs.setInt(1, year);/ResultSet rs = stmt.executeQuery(call proc\_records);ResultSet rs = cs.executeQuery();Map map = new HashMap();while (rs.next() map.put(rs.getString(1), rs.getString(2);rs.close();stmt.close();return map;); catch ( org.springframework.dao.DataAccessExceptio。

13、sum(checkProjectPayMoney) from JiLiangZhiFu where projectId = project\_id and payType = type\_id and enterDate CAST(year as varchar(4) and enterDate CAST(year+1 as varchar(4) and type = outer group by payType-一个项目某一支付类别金额存入insert into map\_table values(project\_id+,+type\_id,payTypeMoney)-一个项目累计支付类别金额set。

14、 sumPayTypeMoney = sumPayTypeMoney + payTypeMoney-一个项目某一支付类别金额重置为set payTypeMoney = 0fetch next from projectType\_cursor into type\_id,type\_name -内层游标向下移动一行end-插入某一项目各个支付类别的金额合计insert into map\_table values(project\_id,sumPayTypeMoney)set sumPayTypeMoney = 0close projectType\_cursordeallocate projectType\_cursorfetch next from project\_cursor into project\_id,project\_name -内层游标处理结束后,外层游标才继续向下移动一行end close project\_cursordeallocate project\_cursorselect \* from map\_tableEND。
