Spring oauth2。重定向到oauth /授权AuthorizationEndpoint不会发生

问题描述：

我正在实施某种SSO系统。我在我的应用程序中使用了Spring安全性oauth 2。我有一个客户端应用程序（localhost：8081）和一个服务器应用程序（localhost：8080）。Spring oauth2。重定向到oauth /授权AuthorizationEndpoint不会发生

用户尝试从客户端应用做一个登录。客户端应用程序依次启动身份验证流程。它发送到服务器应用程序 AUTH请求http://localhost:8080/authorize?response_type=code&client_id=client&scope=openid+email+address+profile+phone&redirect_uri=localhost:8081/login&nonce=3fc29332c5377&state=18960fbd838be
有一个重定向到登录页面，并输入凭据并提交表单认证成功上服务器后。
之后，我期待继续流动授权，去到OAuth /在irder授权终点org.springframework.security.oauth2.provider.endpoint.AuthorizationEndpoint 生成授权码，并发送回客户端应用。但它没有。

请帮我澄清一下为什么？为什么在成功认证后流程不会进入oauth /授权终点。

这是我登录andpoint配置：

<security:http pattern="/mylogin" 
       create-session="stateless" 
       entry-point-ref="oauthAuthenticationEntryPoint"> 
    <security:intercept-url pattern="/mylogin" access="permitAll"/> 
    <security:csrf disabled="true"/> 
    <security:custom-filter before="PRE_AUTH_FILTER" ref="customAuthenticationFilter"/> 
    <security:custom-filter ref="authRequestFilter" after="SECURITY_CONTEXT_FILTER" /> 
    <security:logout logout-url="/logout" /> 
    <security:anonymous /> 
    <security:expression-handler ref="oauthWebExpressionHandler" /> 
    <security:headers> 
     <security:frame-options policy="DENY" /> 
    </security:headers> 
</security:http>

这是我的自定义身份验证过滤器：

public class CustomAuthenticationFilter extends AbstractAuthenticationProcessingFilter { 

private static Logger logger = LoggerFactory.getLogger(CustomAuthenticationFilter.class); 

public CustomAuthenticationFilter() { 
    super("/mylogin"); 
} 

@Override 
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException, IOException, ServletException { 
    if (!HttpMethod.POST.name().equals(request.getMethod())) { 
     if(logger.isDebugEnabled()) { 
      logger.debug("Authentication method not supported. Request method: " + request.getMethod()); 
     } 
     throw new AuthenticationServiceException("Authentication method not supported"); 
    } 
    String username = request.getParameter("j_username"); 
    String password = request.getParameter("j_password"); 
    if (StringUtils.isBlank(username) || StringUtils.isBlank(password)) { 
     throw new AuthenticationServiceException("Username or Password not provided"); 
    } 
    UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(username, password); 
    setDetails(request, authRequest); 
    Authentication auth = this.getAuthenticationManager().authenticate(authRequest); 
    return auth; 
} 

protected void setDetails(HttpServletRequest request, 
          UsernamePasswordAuthenticationToken authRequest) { 
    authRequest.setDetails(authenticationDetailsSource.buildDetails(request)); 
}

}

没有我的授权服务器的配置：

<oauth:authorization-server 
    client-details-service-ref="defaultOAuth2ClientDetailsEntityService" 
    authorization-request-manager-ref="connectOAuth2RequestFactory" 
    token-services-ref="defaultOAuth2ProviderTokenService" 
    user-approval-handler-ref="tofuUserApprovalHandler" 
    request-validator-ref="oauthRequestValidator" 
    redirect-resolver-ref="blacklistAwareRedirectResolver" 
    authorization-endpoint-url="/authorize" 
    token-endpoint-url="/token" 
    error-page="/error"> 

    <oauth:authorization-code authorization-code-services-ref="defaultOAuth2AuthorizationCodeService"/> 
    <oauth:implicit /> 
    <oauth:refresh-token/> 
    <oauth:client-credentials/> 
    <oauth:password/> 
    <oauth:custom-grant token-granter-ref="chainedTokenGranter" /> 
    <oauth:custom-grant token-granter-ref="jwtAssertionTokenGranter" /> 
    <oauth:custom-grant token-granter-ref="deviceTokenGranter" /> 

</oauth:authorization-server> 

<bean id="oauthAccessDeniedHandler" class="org.springframework.security.oauth2.provider.error.OAuth2AccessDeniedHandler" />

答

我找到了原因。

create-session =“无状态”是认证尚未保存在安全上下文中的原因。

这就是为什么在处理授权请求（成功验证后）的阶段，FilterSecurityInterceptor中存在Access Denied异常。
