SpringMVC+Hibernate +MySql+ EasyUI实现POI导出Excel(二)

SpringMVC+Hibernate +MySql+ EasyUI实现CRUD(一)

大概的截图。很简单的小功能

注：使用的是MyEclipse 10.0 javaee 6.0 tomcat 6.0 导出指定列名。使用VO接受参数。

SpringMVC+Hibernate +MySql+ EasyUI实现POI导出Excel(二)  和 批量删除数据 小功能的实现

1.datagrid新加的导出按钮代码

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

2.批量删除的js代码和html代码

    /****批量删除******/
    $(function(){
    $("#deletes").bind("click",function(){
        var selrow = $("#dg").datagrid("getSelections");
        if(selrow.length==0){
        alert("至少选择一条数据");
        return false;
        }
        var ids=[];
        for(var i = 0; i < selrow.length; i++){
            var id = selrow[i].id;
            ids.push(id);
        }
        if(confirm("您确定批量删除")){
            $.getJSON("${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" >批量删除</a>

3.导出Controller代码

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;

/**

@Controller
@RequestMapping(value="/export")
public class ExportController {
    UserService userService;
    UserDao userDao;
    ExportExcel<T>  excelService = new ExportExcel<T>();
    /**

     * @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);//查询所有的数据

        String haders[] = new String []{"序号","名称","年龄","生日","地址","学号"};

        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;
    }


    
}
