调用上面的方法进行生成excel:

/*** 导出所选记录(装备)* @param request* @param response* @author cjianquan* 2015-1-29*/@RequestMapping(params = "exportZbxx")public void exportZbxx (HttpServletRequest request,HttpServletResponse response){String[] ids = request.getParameterValues("ids[]");String conIds = "";for(String s:ids){conIds+="'"+s+"',";}conIds = conIds.substring(0,conIds.length()-1);StringBuilder querySql = new StringBuilder("select ZHUANGBEI_ZBMC,");querySql.append("ZHUANGBEI_ZBBH,(select zblx_mc  from TBL_BASE_ZBLX a where a.zblx_unid=t.ZHUANGBEI_ZBLX) ZHUANGBEI_ZBLX,").append("ZHUANGBEI_SSDWMC,").append("ZHUANGBEI_ZBSJ,").append("(select typename from t_s_type  where typegroupid =(select id  from t_s_typegroup where typegroupcode='xxcg_jczb_zwzt') and typecode=t.ZHUANGBEI_ZBZT) ZHUANGBEI_ZWZT,").append("ZHUANGBEI_SCCJ,").append("(select typename from t_s_type  where typegroupid =(select id  from t_s_typegroup where typegroupcode='xxcg_jczb_zlzk') and typecode=t.ZHUANGBEI_ZBZT) ZHUANGBEI_ZLZK,").append("(select typename from t_s_type  where typegroupid =(select id  from t_s_typegroup where typegroupcode='xxlb_zbgl_zbzt') and typecode=t.ZHUANGBEI_ZBZT) ZHUANGBEI_ZBZT").append(" from TBL_BASE_ZHUANGBEI t where ZHUANGBEI_UNID in ("+conIds+")");List<Map<String,Object>> zbxxList = this.systemService.findForJdbc(querySql.toString());Map<String,Object> exportBeans = new HashMap<String, Object>();String templateFile = "export/xlsTemplates/zbxxExportTemplate.xls";String destFileName = "export/output/zbxx.xls";exportBeans.put("resultList", zbxxList);JxlsUtils.exportExcel(templateFile, exportBeans, destFileName);}

js导出Excel:

//导出所选记录//add by cjianquan on 2015-1-29 function exportXls(){var ids = [];var rows = $('#zbxxList').datagrid('getSelections');    if(rows.length<=0){alert("请选择要导出的记录!");return false;} for(var i=0; i<rows.length; i++){ids.push(rows[i].id);}//ids.join(',');$.ajax({type:'POST',async:false,data:{"ids":ids},url:'./zbxxController.do?exportZbxx',success:function(data){window.location.href='export/output/zbxx.xls';},error:function(XMLHttpRequest,textStatus,errorThrown){alert("导出Excel失败!");}});}

zbxxExportTemplate.xls模板文件内容如下：
