javaweb代码学习总结

什么也不说了，直接上代码：

复制代码 代码如下:

String path = ontextPath();

String basePath = cheme()+"://"+erverName()+":"+erverPort()+path+"/";

/**

page:页码

pageSize:每页的记录条数

此方法除了传入page和pageSize之外，还应知道的有三个参数：

一、表的全部数据，json串格式，可通过action查询数据库得到。

二、表头所对应的列的key及名称，也是json串格式

三、表所对应的id

注：此处只是适合表头只有一行，且事先写好的.情况。您可以根据需要改一下，逻辑思路就是这样，欢迎批评指正。
