    	        }finally{    
    	            outStream.close();    
    	        }    
    		} catch (Exception e) {
    			e.printStackTrace();
    		}
        
        }

2、前台代码

//导出同环比分析
    function linkAnalysisExport(){
        //设置高级查询条件
        var param = $('#grid_linkAnalysis').datagrid('options').queryParams;
    
        var form = $("<form method='post'></form>");
        form.attr("action",getRootPath()+"/runindex/linkAnalysis/exportLinkAnalysis.do");
        $.each(param,function(key,value){
                var attr=null;
                if(value){
                    attr = $("<input>").attr("type","hidden").attr("name",key).attr("value",value);
                }else{
                    attr = $("<input>").attr("type","hidden").attr("name",key).attr("value","");
                }
                if(attr!=null){
                    form.append(attr);
                }
        });
        form.appendTo("body").submit();
    }
