实现功能：java导出excel表

1、jsp代码

  1.  <form id="zhanwForm" action="<%=path%>/conferences.do?" target="_self"  method="get" >
  2.           <input type="hidden" name="method" value="outData"/>
  3.           <input type="hidden" name="compassId" value='1'/>
  4.           <input type="hidden" name="fromWhere" value="AAAA"/>
  5.  
  6.  </from>

2、js代码

  1.       $(".daochu1").click(function(){
  2.               var bank = new Array();
  3.                $.each($(".guangGaoLeiXing").find("input:checked"), function () {
  4.                      bank.push($(this).val());
  5.              });
  6.               if(bank == false){
  7.                   alert("请选择要统计类型");
  8.               }else{
  9.                $("#zhanwForm").submit();
  10.              }
  11.            })
  12.  
  13.           $(".lyBtn").click(function(){
  14.               $(".mask").show();
  15.              $(".tishiDiv").show();
  16.              $.ajax({
  17.                  url : '<%=path %>/conferences.do?method=getUserLy&fromWhere=csco',
  18.                  type : 'GET',
  19.                  dataType : 'json',
  20.                  success : function(data) {
  21.                       $(".mask").hide();
  22.                       $(".tishiDiv").hide();
  23.                        window.open(data.url);
  24.                  }
  25.                })
  26.           });

3、action处理代码

  1.  //导出数据
  2.      //SELECT SUBSTRING(create_time,1,10) s,COUNT(*)  FROM data_read WHERE data_id IN (SELECT data_id FROM DATA WHERE model_id=2 OR model_id=27)  GROUP BY s
  3.      @RequestMapping(params = "method=outData",method = RequestMethod.GET)
  4.      public void outCompassTongJiData(Integer compassId,String fromWhere,ModelMap model,HttpServletRequest request,HttpServletResponse response)
  5.      {
  6.          String urlPath =  request.getScheme()+"://"+request.getServerName()+request.getContextPath();
  7.          XSSFWorkbook rwb1 = new XSSFWorkbook();
