第一种方法(继承SessionAware类来取得session,然后用invalidate()方法清理)
public class ExitAction extends ActionSupport implements SessionAware{
@Override
public String execute() throws Exception {
HttpServletRequest request = ServletActionContext.getRequest();
HttpSession session1 = request.getSession();
session1.invalidate();
return super.execute();
}
public void setSession(Map arg0) {
}
}
//第二种方法（用ActionContext取session,然后用clear()方法清理）
public class ExitAction extends ActionSupport{
@Override
public String execute() throws Exception {
ActionContext ac = ActionContext.getContext();
Map session = ac.getSession();
session.clear();
return super.execute();
}
}
//第三种方法（一样用ActionContext取session,然后取一个Session的KEY，清除该KEY的session,这种办法可以选择性的清理你要清理的session）
public class ExitAction extends ActionSupport{
@Override
public String execute() throws Exception {
ActionContext ac = ActionContext.getContext();
Map session = ac.getSession();
session.remove(“buser”);
session.remove(“guser”);
session.remove(“fuser”);
return super.execute();
}
}
