我正在尝试使一个简单的Spring OAuth2 SSO应用程序正常工作，但我一直无法这样做。这是发生的步骤和结果：

1. 命中端点/user，由OAuth2保护
2. 我被转发到一个简单的Spring OAuth2授权服务器
3. 我认证到授权服务器
4. 我批准了访问

5. 然后，我在OAuth2 SSO应用程序上看到带有以下内容的白标错误页面：

   Whitelabel Error Page
   

   This application has no explicit mapping for /error, so you are seeing this as a fallback.

   Mon Jul 13 08:19:18 EDT 2015
   There was an unexpected error (type=Unauthorized, status=401).
   Authentication Failed: Could not obtain access token

授权代码在URL中。这是下面的示例URL：

http://localhost:8083/login?code=9s63rU&state=Fo9S2M

我没有看到HTTP POST授权服务器/oauth/token端点获取JWT。我通过/trace授权服务器上的端点对此进行了验证。

异常堆栈为：

如果您需要授权服务器的代码，请告诉我。

::更新1 ::

我开始调试此程序，然后发现抛出了InvalidRequestException带有消息：Possible CSRF detected - state parameter was present but no state could be foundon line 244of
的实际异常AuthorizationCodeAccessTokenProvider。

我试图Oauth2SsoConfigurerAdapter对此进行修改，但仍然遇到相同的异常：

@Configuration
protected static class SecurityConfiguration extends OAuth2SsoConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.logout().and().antMatcher("/**").authorizeRequests()
                .antMatchers("/index.html", "/home.html", "/", "/login").permitAll()
                .anyRequest().authenticated().and().csrf()
                .csrfTokenRepository(csrfTokenRepository()).and()
                .addFilterAfter(csrfHeaderFilter(), CsrfFilter.class);
    }

    private Filter csrfHeaderFilter() {
        return new OncePerRequestFilter() {
            @Override
            protected void doFilterInternal(HttpServletRequest request,
                                            HttpServletResponse response, FilterChain filterChain)
                    throws ServletException, IOException {
                CsrfToken csrf = (CsrfToken) request.getAttribute(CsrfToken.class
                        .getName());
                if (csrf != null) {
                    Cookie cookie = WebUtils.getCookie(request, "XSRF-TOKEN");
                    String token = csrf.getToken();
                    if (cookie == null || token != null
                            && !token.equals(cookie.getValue())) {
                        cookie = new Cookie("XSRF-TOKEN", token);
                        cookie.setPath("/");
                        response.addCookie(cookie);
                    }
                }
                filterChain.doFilter(request, response);
            }
        };
    }

    private CsrfTokenRepository csrfTokenRepository() {
        HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository();
        repository.setHeaderName("X-XSRF-TOKEN");
        return repository;
    }
}

::更新2 ::

在InvalidRequestException被抛出，因为preservedState从DefaultAccessTokenRequest被返回null（见line 239的AuthorizationCodeAccessTokenProvider）。

该preservedState是对设置DefaultAccessTokenRequest在Oauth2RestTemplate上line 212，我确定DefaultOauth2ClientContext地图是空和返回null。

接下来，我将尝试验证setPreserveState呼叫DefaultOAuth2ClientContext。

::更新3 ::

我将客户端配置更新为使用Github而不是我自己的Spring OAuth2授权服务器，它可以工作。对我来说，这表明我的授权服务器配置可能有问题。

我将尝试在OAuth服务器上进行一些调试，以查看是否可以找出问题所在。

::更新4 ::

成功！我在同一主机上但不同端口上运行OAuth2授权服务器和客户端服务器。当我将客户端的上下文路径设置为除根目录以外的其他路径时，它们全部开始工作。

我怀疑这JSESSIONID和Cookie有关。谁能将我链接到文档，以解释其工作原理以备将来参考？

谢谢！
