jquery datatable后台封装数据示例代码

try {
params = managerService.getUserList(参数);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String count = (String)params.get("COUNT");//总数
String[][] strData = (String[][])params.get("AO_DATA");//当前页显示的集合
return successed(new DataTableReturnObject(Integer.parseInt(count) , Integer.parseInt(count), sEcho, strData));
}

4.查询方法

public Map<Object, Object> getUserList(Map<Object, Object> queryParams)
throws Exception { 
String iCount = 总记录数;
// 将查询结果转换为一个二维数组
String[][] data = {};
if (lstUser != null && lstUser.size() > 0) {
int record = lstUser.size();
data = new String[record][];
for (int i = 0; i < lstUser.size(); i++) {
User objUser = (User) lstUser.get(i);
JSONUser jsonUser = new JSONUser();
BeanUtils.copyProperties(jsonUser, objUser);
data[i] = jsonUser.toArray();
}
}
queryParams.clear();// 情况map,重新设值使用
queryParams.put("AO_DATA", data);
queryParams.put("COUNT", iCount);
return queryParams;
}

注意存放的数组对象的属性必须与前端页面显示的列保持一样的个数
