Map<String, Object> jsonMap = new HashMap<String, Object>();//定义map后台打印
jsonMap.put("total", pages.getCountrecord());
jsonMap.put("rows", pages.getList());
response.getWriter().write(JSONArray.toJSONString(jsonMap));
另外实体类结构：
private Integer id;
private SysUser sysUser;
private Channel channel;
private String title;
private String subhead;
private String summary;
private String content;
private String thumbnail;
private String author;
private Date createDate;
private Date publishDate;
private Date updateDate;
private String bitIndex;
private String status;
private String attachment;
private String type;
private Integer click;
private String name;
private String address;
private String phone;
private String linkUrl;
private String licenseKey;
private String typeName;
private String video;
private Integer indexNum;
private String froms;
前台easyui ：
<table class="easyui-datagrid" data-options="rownumbers:true,singleSelect:true,pagination:true,url:'topic/list.yhtml?channelId=${channel.id}',method:'get'">
<thead>
<tr>
<td data-options="field:'title',align:'center',width:430,autoRowHeight:false">文章标题</td>
<td data-options="field:'indexNum',align:'center',width:430,autoRowHeight:false">置顶排序</td>
<td data-options="field:'createDate',align:'center',width:430,autoRowHeight:false">创建时间</td>

<td data-options="field:'controller',align:'center',width:430,autoRowHeight:false">操作</td>
</tr>
</thead>
</table> 为什么easyui 读不到值啊？
