一个项目也不难啊

   第二个项目开始做了些，其实我感觉真的不难，加上了Struts之后，我觉得好象也只是一个普通的工具，用起来跟之前真没什么区别，搞不懂啊，为什么很多人都说它很难，就连李老师也说，之前学习的时候很难，不过回想起李老师说的话，只要形成了正确的开发思路，一切都很简单。

    在这次开发的项目中，我觉得数据库的关闭始终是一个比较麻烦的事，真不知道什么时候能解决这样的问题，可是Struts 1.x使起来好象问题也特别的多，自己只是感觉到有问题，至于什么具体的情况还真想不明白，慢慢来吧，有MLDN的支持呢，我坚信啊。

4.1. 1、如何判断用户是否有某个操作的权限


已解决

第一步：
定义一个权限对象：Power，
特殊之处：（1）该对象的一个特殊属性，Map对象，即权限名及权限值，
（2）还有就是该Power类的有参构造方法
package mldn.lin.vo;

import java.util.Map;
import java.util.TreeMap;

public class Power {
private boolean userflagC;
private boolean userflagR;
private boolean userflagU;
private boolean userflagD;

private boolean itemflagC;
private boolean itemflagR;
private boolean itemflagU;
private boolean itemflagD;

private boolean subitemflagC;
private boolean subitemflagR;
private boolean subitemflagU;
private boolean subitemflagD;

private boolean courseflagC;
private boolean courseflagR;
private boolean courseflagU;
private boolean courseflagD;

private boolean libraryflagC;
private boolean libraryflagR;
private boolean libraryflagU;
private boolean libraryflagD;

private boolean teacherflagC;
private boolean teacherflagR;
private boolean teacherflagU;
private boolean teacherflagD;

private boolean infoflagC;
private boolean infoflagR;
private boolean infoflagU;
private boolean infoflagD;

private boolean logflagC;
private boolean logflagR;
private boolean logflagU;
private boolean logflagD;

private boolean adminflagC;
private boolean adminflagR;
private boolean adminflagU;
private boolean adminflagD;

private boolean deptflagC;
private boolean deptflagR;
private boolean deptflagU;
private boolean deptflagD;

// setter getter
}

第二步：当管理员登陆成功后，将权限保存在这个Power对象中，并放在session中
//管理员登陆成更后，将其权限设置到session中
     Power power=new Power(tadmin);
     request.getSession().setAttribute("power", power);

第三步：操作前的判断，例如查看一级栏目前的权限判断
public ActionForward list(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) {
  //TitemForm titemForm = (TitemForm) form;// TODO Auto-generated method stub
  if(((Power)request.getSession().getAttribute("power")).getPower().get("itemflagR")){
   Limit limit=RequestUtils.getLimit(request);
   Map searchMap=limit.getFilterSet().getPropertyValueMap();
   Map sortMap=limit.getSort().getSortValueMap();
   try {
    int allRecorders = DAOFactory.getITitemDAOInstance().getAllRecorder(searchMap);
    int[] startEndRow=RequestUtils.getRowStartEnd(request, allRecorders, 5);
    List<Titem> allTitem=DAOFactory.getITitemDAOInstance().doSelectAll(startEndRow[0], startEndRow[1], searchMap, sortMap);
    request.setAttribute("allTitem", allTitem);
   } catch (Exception e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
   return mapping.findForward("titemlist");
  }else{
   ActionMessages errors=null;
   errors=new ActionMessages();
   errors.add("itemflagR",new ActionMessage("itemflagR.not"));
   this.addErrors(request, errors);
   return mapping.getInputForward();
  }
}
