<!--最新整理-->
这是以前做过的一套程序，研究了一天，通过搜索资料自己修改出来找个功能，虽然最后在项目中做出来的效果很不完美，但是这个功能却是我研究的结果，还是拿出来跟大家分享下，有能力的朋友仔完善一下！
功能：从数据库里获取页面的模块数据，根据cookie值将模块布局在页面，并且拖动模块可以随意部署页面布局，并且将cookie值更新至数据库
-----------------------------------------------------------------------------------------------------------

sqlMethod dbo = new sqlMethod();
String sql = "Select u_ui from Tmp_users where u_id=6";
ArrayList list = new ArrayList();
list = dbo.rsQuery(sql);
String cool = ""; //这个是在数据库存储的COOKIE值
if(list.size()>0)
{
String t[] = (String[])list.get(0);
cool=t[0];
