我在本教程后面使用了socialauth库： https://github.com/3pillarlabs/socialauth/wiki/Getting-Started-with-implementing-SocialAuth
一切正常，我只是不明白在第3步结束后存储在哪里/什么。我的意思是我不想强迫用户登录每次点击。我试图从例子中弄清楚这一点，但我不能......
这就是我所拥有的：
@WebServlet("/success")
public class AfterOAuth extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
try {
// get the auth provider manager from session
SocialAuthManager manager = (SocialAuthManager) req.getSession().getAttribute("authManager");
// call connect method of manager which returns the provider object.
// Pass request parameter map while calling connect method.
Map<String, String> paramsMap = SocialAuthUtil.getRequestParametersMap(req);
AuthProvider provider = manager.connect(paramsMap);
// get profile
Profile p = provider.getUserProfile();
// you can obtain profile information
resp.getOutputStream().print(p.getFirstName());
// OK, everything is fine by now what should I store in my Session?
} catch (Exception e) {
throw new ServletException(e);
}
}
}
答案 0 :(得分：0)
好的，我使用提供的CDI Class找到了一个解决方案，并简单地覆盖了init（）和servlet部分：

现在我可以在任何需要的地方使用@Inject SocialAuth。
