SpringMVC+Hibernate +MySql+ EasyUI實現(xiàn)CRUD(一)

大概的截圖。很簡單的小功能

注：使用的是MyEclipse 10.0 javaee 6.0 tomcat 6.0 導(dǎo)出指定列名。使用VO接受參數(shù)。

SpringMVC+Hibernate +MySql+ EasyUI實現(xiàn)POI導(dǎo)出Excel(二)? 和 批量刪除數(shù)據(jù) 小功能的實現(xiàn)

1.datagrid新加的導(dǎo)出按鈕代碼

???????????????/*導(dǎo)出excel?按鈕*/toolbar:[{id:'btnsave',text:'導(dǎo)出',iconCls:'icon-save',handler:function(){var?url?=?'${ctx}/export?method=sheetsExport';window.location.href=url;}}]

2.批量刪除的js代碼和html代碼

????/****批量刪除******/$(function(){$("#deletes").bind("click",function(){var?selrow?=?$("#dg").datagrid("getSelections");if(selrow.length==0){alert("至少選擇一條數(shù)據(jù)");return?false;}var?ids=[];for(var?i?=?0;?i?<?selrow.length;?i++){var?id?=?selrow[i].id;ids.push(id);}if(confirm("您確定批量刪除")){$.getJSON("${ctx}/user/delall",{"array[]":ids},function(data){alert(data.msg);if(true?==?data.success){$("#dg").datagrid("reload");}})}})})html<a?href="javascript:void(0);"?id="deletes"?class="blank_btn"?>批量刪除</a>

3.導(dǎo)出Controller代碼

package?com.xs.demo.controller;import?java.io.OutputStream; import?java.net.URLEncoder; import?java.text.SimpleDateFormat; import?java.util.Date; import?java.util.List; import?java.util.Map;import?javax.servlet.http.HttpServletRequest; import?javax.servlet.http.HttpServletResponse;import?org.apache.poi.ss.formula.functions.T; import?org.springframework.stereotype.Controller; import?org.springframework.web.bind.ServletRequestUtils; import?org.springframework.web.bind.annotation.RequestMapping;import?com.xs.demo.dao.UserDao; import?com.xs.demo.entity.Userinfo; import?com.xs.demo.service.ExportExcel; import?com.xs.demo.service.UserService; import?com.xs.demo.util.ExcelUtils; import?com.xs.demo.util.JsGridReportBase; import?com.xs.demo.util.StringUtil; import?com.xs.demo.util.TableData; /***?*?類名稱:ExportController?*?@author?宗瀟帥*?2014-11-18*/ @Controller @RequestMapping(value="/export") public?class?ExportController?{UserService?userService;UserDao?userDao;ExportExcel<T>??excelService?=?new?ExportExcel<T>();/***?*?@param?request*?@param?response*?@throws?Exception*/@SuppressWarnings({?"rawtypes",?"unchecked"?})@RequestMapping(params="method=sheetsExport")public?void?exportSheets(HttpServletRequest?request,HttpServletResponse?response)throws?Exception?{Userinfo?userinfo?=?new?Userinfo();List?list?=?userService.lists(userinfo);//查詢所有的數(shù)據(jù)String?haders[]?=?new?String?[]{"序號","名稱","年齡","生日","地址","學(xué)號"};SimpleDateFormat?format?=?new?SimpleDateFormat("yyyy-MM-dd");String?filename?=?format.format(new?Date().getTime())+".xls";response.setContentType("application/ms-excel;charset=UTF-8");response.setHeader("Content-Disposition",?"attachment;filename=".concat(String.valueOf(URLEncoder.encode(filename,?"UTF-8"))));OutputStream?out?=?response.getOutputStream();try?{excelService.exportExcel(haders,list,out);System.out.println("success");}?catch?(Exception?e)?{System.out.println("error");}finally{out.close();}}public?UserService?getUserService()?{return?userService;}public?void?setUserService(UserService?userService)?{this.userService?=?userService;}public?UserDao?getUserDao()?{return?userDao;}public?void?setUserDao(UserDao?userDao)?{this.userDao?=?userDao;}public?ExportExcel<T>?getExcelService()?{return?excelService;}public?void?setExcelService(ExportExcel<T>?excelService)?{this.excelService?=?excelService;}}

3.http://my.oschina.net/xshuai/blog/304321? 工具類代碼在這里。

4.userdao代碼

????public?List<Userinfo>?lists(Userinfo?userinfo)?{return?super.list(Userinfo.class);}
