Cookies实现单点登录

1、登录时在action中设置cookies

String username = loginForm.getUsername();
String password = loginForm.getPassword();

Cookie cookie = new Cookie("sso",new BASE64Encoder().encode((username+password).getBytes()));
cookie.setDomain(".192.168.0.145");
cookie.setMaxAge(60);
cookie.setPath("/");
response.addCookie(cookie);

2、在应用的action中判断用户

Cookie[] cookies = request.getCookies();
if(cookies!=null){
   for (Cookie cookie : cookies) {
      if(cookie.getName().equals("sso")){
         String s = cookie.getValue();
         s = new String(new BASE64Decoder().decodeBuffer(s));
         System.out.println(s);
      }
   }
}
