处理UserRedirectRequiredException（需要重定向才能获得用户批准）

spring-boot

介绍

一周前，我开始使用OAuth2框架（使用Spring Boot
v1.3.0.M4）开发应用程序。对我来说是全新的体验。因此，我尝试使其尽可能简单以更好地理解它。我正在使用Spring Security
OAuth2，并且在正确使用它方面遇到困难。

我想做的事

当此人授权我的应用程序时，对用户进行身份验证。实际上，我不希望他在我的应用程序上注册，因此他可以自由使用它，而不必填写无聊的表格进行注册。

遇到的问题

我找不到处理UserRedirectRequired异常的方法。因为我不这样做，所以永远不会将用户重定向到授权页面，并且会引发（并处理）异常。

我的应用程序

StandardController.java

package org.test.oauth.web;

import java.security.Principal;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class StandardController {

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String getHelloWorld() {
        return "Hello world !";
    }

    @RequestMapping(value = "/user", method = RequestMethod.GET)
    public Principal getUser(Principal principal) {
        return principal;
    }
}

StandardConfiguration.java

package org.test.oauth.configuration;

import java.util.Arrays;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.security.oauth2.client.EnableOAuth2Sso;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.oauth2.client.OAuth2ClientContext;
import org.springframework.security.oauth2.client.filter.OAuth2ClientContextFilter;
import org.springframework.security.oauth2.client.resource.OAuth2ProtectedResourceDetails;
import org.springframework.security.oauth2.client.token.grant.code.AuthorizationCodeResourceDetails;
import org.springframework.security.web.access.ExceptionTranslationFilter;

@Configuration
@EnableOAuth2Sso
public class StandardConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    private OAuth2ClientContextFilter oauth2ClientContextFilter;

    @Autowired
    private OAuth2ClientContext oauth2ClientContext;


    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // @formatter:off
        http
        .authorizeRequests().antMatchers("/login").anonymous().and()
        .authorizeRequests().anyRequest().authenticated().and()
        .httpBasic().and()
        .addFilterAfter(oauth2ClientContextFilter, ExceptionTranslationFilter.class);
        // @formatter:on
    }

//  org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [org.springframework.security.oauth2.client.OAuth2RestOperations] is defined: expected single matching bean but found 2: restTemplate,userInfoRestTemplate
//  @Bean
//  public OAuth2RestOperations restTemplate() {
//      return new OAuth2RestTemplate(bnetResource(), oauth2ClientContext);
//  }

    @Bean
    public OAuth2ProtectedResourceDetails bnetResource() {
        AuthorizationCodeResourceDetails resource = new AuthorizationCodeResourceDetails();
        resource.setId("bnet");
        resource.setClientId("***");
        resource.setClientSecret("***");
        resource.setAccessTokenUri("https://eu.battle.net/oauth/token");
        resource.setUserAuthorizationUri("https://eu.battle.net/oauth/authorize");
        resource.setScope(Arrays.asList("wow.profile"));
        return resource;
    }
}

我的问题

当我进入根应用程序时，由于我未通过身份验证，Spring Security会将我重定向。它将我重定向到登录页面。Spring
Boot默认配置会引发和处理许多异常，但是当创建并引发UserRedirectRequiredException时，没有过滤器会处理它。在调试应用程序时，我发现由oauth2ClientContextFilter找到的最后一个异常是AccessDeniedException。我怀疑我的过滤器（实际上是默认配置中的OAuth2ClientContextFilter）在过滤器链中设置不正确。

查看堆栈跟踪，我试图更改过滤器链中过滤器的顺序。因此，我尝试将OAuth2ClientContextFilter放在OAuth2ClientAuthenticationProcessingFilter之后。不幸的是，当我启动该应用程序时，发生错误，告诉我该过滤器未注册。

更改

.addFilterAfter(oauth2ClientContextFilter, ExceptionTranslationFilter.class);

至

.addFilterAfter(oauth2ClientContextFilter, OAuth2ClientAuthenticationProcessingFilter.class);

因此，请您帮助我解决这个问题并摆脱这个问题。我知道关于此问题有很多问题已得到解答，但并不能按需要帮助我。

感谢您花费时间为我提供帮助。

@Stilleur解决方案的替代方法如下。它在Spring官方指南中的“处理重定向”标题下建议：https : //spring.io/guides/tutorials/spring-boot-
oauth2/

@Bean
public FilterRegistrationBean oauth2ClientFilterRegistration(
    OAuth2ClientContextFilter filter) {
  FilterRegistrationBean registration = new FilterRegistrationBean();
  registration.setFilter(filter);
  registration.setOrder(-100);
  return registration;
}
