Struts清楚session方法

//第一種方法(繼承SessionAware類來取得session,而後用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) {


}

}
//第二種方法（用ActionContext取session,而後用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();
}

}
//第三種方法（同樣用ActionContext取session,而後取一個Session的KEY，清除該KEY的session,這種辦法能夠選擇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();
}

}
