同一个Jsp中的两个按钮连接到两个方法

问题描述

我正在使用jsp，servlet和java做一个网站。我在同一个Jsp页面（Login.jsp）中有两个按钮（登录和注销）。它的方法（loginSession和logoutSession）也在同一个servlet文件（GetServlet.java）中。我的问题是如何将登录按钮连接到loginSesssion并注销按钮到logoutSession？

推荐答案

String type request.getParameter("ReqType")
if("LOGOUT".equals(type)){
//do logout operation
}else if("LOGIN".equals(type)){
//do login operation
}

处理2

=============

1.假设请求的网址为

http：// localhost：8080 / login

http：// localhost：8080 / logout

2.在web.xml文件中添加两个url模式指向相同的servlet



3.阅读servlet中的Uri信息

Process 2

http://localhost:8080/login
http://localhost:8080/logout
2. add both url pattern in you web.xml file to point the same servlet

3.And read the Uri info in servlet

String uri = request.getRequestURI();
if("/login".equals(uri)){
//do login operation
}else if("/logout".equals(uri)){
//do logout operation
}
