struts2里头使用JSON

struts2里面使用JSON
页面引进jquery

<script  type="text/javascript" src="<%=request.getContextPath()%>/js/jquery.js"></script>function test(){var url = "/donategroup/queryMemberDonate.action";$.getJSON(url, function(json){alert(json);//json是一个json数组 for(var i=0;i<json.length;i++){ alert(json[i]); alert('amount:'+json[i].amount); alert('bankName:'+json[i].bankName); alert('memberId:'+json[i].memberId); }});}

在queryMemberDonate.action里面查询出来一个list，
转换成json,ps:MemberDonateRecord对象有的属性：amount、bankName、memberId等等

List<MemberDonateRecord> memberdonaterecord=donaterecordservice.queryMemberDonate(memberId,requestId,page,size,name,beginDate,endDate);JSONArray ja = JSONArray.fromObject(memberdonaterecord);ServletActionContext.getResponse().setCharacterEncoding("UTF-8");final PrintWriter out = ServletActionContext.getResponse().getWriter();out.write(ja.toString());
