基于 angularjs+jfinal 的 excel文件导出

Js：
$scope.expExcel = function() {
var start=$("#start").val();
var end    =$("#end").val();
var state =$scope.searchInfo.state;
var name =$scope.searchInfo.name;

window.open("withdraw/expExcel?state=" +state
+ "&start=" + start+ "&end=" + end+ "&name=" + name  );

};

controller ：
@Clear
public void expExcel() throws ParseException, IOException {

String start = getPara("start");
String end = getPara("end");
