jsp頁面：

$.ajax({
	type:'POST',
	url:"../user/userInfoExportExcel?org.orgId="+org_id+"&user.uesrName="+encodeURI(encodeURI(user_name)),
	success:function(json){
		var Json = eval("(" + json.jsonResult + ")");
		if(Json.result!="fail"){
			window.location.href="../orgtree/exportExcel.action?fileName="+Json.result;
				ajaxbg.hide();
		}else{
			alertMsg.error('匯出失敗！');
			ajaxbg.hide();
			}
		}
	});
 

java後臺：

if (getParameterValue("user.uesrName") != null && !getParameterValue("user.uesrName").equals("")) {
	String decodeUserName = java.net.URLDecoder.decode((String)getParameterValue("user.uesrName"),"utf-8");
	c.andUserNameLike("%" + decodeUserName.trim() + "%");
}
