}
public String getPrivilege() {
return privilege;
}
public void setPrivilege(String privilege) {
this.privilege = privilege;
}
} 3 加两个Tag(Page与Field)：
SecurityTagForPage.java：
package com.**.**.taglib;
import java.util.*; public class SecurityTagForPage extends TagSupport
{
private int permissionID;
public int doEndTag() throws JspException
{
HttpSession session = pageContext.getSession(); //登陆时把该user的userProfile放到session里 UserProfile userProfile = (UserProfile)session.getAttribute("userProfile");
Collection collection= userProfile.getUserPermissions();
Iterator it = collection.iterator() ;
while(it.hasNext())
{
UserPermission userPermission = (UserPermission)it.next();
if ((permissionID == userPermission.getPermissionId()))
{
return EVAL_PAGE;
}
}
return SKIP_PAGE;
} public int getPermissionID()
{
return permissionID;
}
public void setPermissionID(int permissionID)
{
this.permissionID = permissionID;
}
} |
