jsp页面：

$.ajax({       url:"${ctx}/inkanetportal/login/consulting.action",       data:"",   type:"post",    dataType:"json",   error:function(){       alert("咨询加载失败!");   },   success:function(jsondata){              var len = jsondata.length;       var html="";       for (var i = 0; i < len; i++) {                html +='<li style="list-style-type: none; width: 5px;height: 29px">' +           '<img src="<%=context %>/images/first/arrow_news.gif" hspace="6" align="absmiddle" />'+           '<a href="'+jsondata[i].consultingUrl + '" class="a_art_target">  '+jsondata[i].consultingTitle +'</a>'+       '<span class="news_date">' + jsondata[i].curdate + '</span>' +                   '</li>';       }              $("#scorll").html(html);  }    });

$.ajax({    url: 'pubService?service=lData',    type: 'post',    data: {     name:name,     Id:Id    },    success: function(result) {          if(result=="success"){            $.messager.alert('管理信息','保存成功。');                                                                             }     }   });

后台：

 public void consulting() throws IOException {    String hql="from TConsultingInfo where consultingEndtime >= to_char(sysdate,'yyyy-mm-dd')";        list=loginService.query(hql);HttpServletResponse respone = ServletActionContext.getResponse();respone.setContentType("text/html;charset=UTF-8");PrintWriter out = respone.getWriter();out.write(JSONArray.fromObject(list).toString());}

json中放的list 使用：JSONArray.fromObject(list).toString() 或者 JSONSerializer.toJSON(temp3).toString(),返回值为字符串时，直接out.write(String);
