Java页面重定向
我想要做的是，当他们第一次点击此方法时，转到免责声明页面，然后随时转到不同的页面。我当前的方法只显示免责声明页面。如果需要进一步解释，请告诉我...谢谢！
public int show(Action action)
throws Exception
{
HttpServletRequest request = action.getRequest();
action.setJspURI("htemp.jsp");
return FORWARD;
}
基本上我需要添加一个 If 来在第一次点击这个方法时进入页面，我想是这样的：
public int show(Action action)
throws Exception
{
HttpServletRequest request = action.getRequest();
--->> If (FIRST TIME HITTING THE METHOD)
{
go here!!!
}
action.setJspURI("htemp.jsp");
return FORWARD;
}
What I want to do is go to a disclaimer page when they first initially hit this method, and then any time after that go to a different page. My current method just takes to me the disclaimer page. Let me know if furthur explanation is needed...thanks!!!
public int show(Action action)
throws Exception
{
HttpServletRequest request = action.getRequest();
action.setJspURI("htemp.jsp");
return FORWARD;
}
Basically I need to add an If to go to a page the first time it hits this method I guess like so:
public int show(Action action)
throws Exception
{
HttpServletRequest request = action.getRequest();
--->> If (FIRST TIME HITTING THE METHOD)
{
go here!!!
}
action.setJspURI("htemp.jsp");
return FORWARD;
}

当用户第一次访问该页面时，在会话层上抛出一个标志。然后，每当有人访问该页面时，您都可以检查该页面是否存在，并相应地重定向他们。唯一的问题是，除非您实施登录系统，否则他们每次访问都必须同意。
PS您应该能够从第一行中获得的请求对象中获取会话。然后只需在该会话对象上使用 setAttribute 即可。
When the person hits the page for the first time, throw a flag on the session layer. Then anytime a person comes to the page you can check to see if it exists or not, and redirect them accordingly. Only problem with that is that they have to agree to it every time they visit unless you implement a login system.
P.S. you should be able to get the Session off of the request object you get in that first line. Then just use setAttribute on that session object.
创建一个会话，以便您可以跟踪是否是用户第一次“点击方法”，这样您就可以选择将他重定向到免责声明或其他任何地方。
Create a session so you can track whether it's a users first "hitting the method", so you can chose to redirect him to the disclaimer or anywhere else.
