spring-security-oauth2 2.0.7刷新令牌UserDetailsS​​ervice配置 - UserDetailsS​​ervice是必需的

Question

请问有关spring-security-oauth2 2.0.7的配置问题.我通过GlobalAuthenticationConfigurerAdapter使用LDAP进行身份验证:

@SpringBootApplication
@Controller
@SessionAttributes("authorizationRequest")
public class AuthorizationServer extends WebMvcConfigurerAdapter {

    public static void main(String[] args) {
        SpringApplication.run(AuthorizationServer.class, args);
    }

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/login").setViewName("login");
        registry.addViewController("/oauth/confirm_access").setViewName("authorize");
    }

    @Configuration
    public static class JwtConfiguration {

        @Bean
        public JwtAccessTokenConverter jwtAccessTokenConverter() {
            JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
            KeyPair keyPair = new KeyStoreKeyFactory(
                    new ClassPathResource("keystore.jks"), "foobar".toCharArray())
                    .getKeyPair("test");
            converter.setKeyPair(keyPair);
            return converter;
        }

        @Bean
        public JwtTokenStore jwtTokenStore(){
            return new JwtTokenStore(jwtAccessTokenConverter());
        }
    }


    @Configuration
    @EnableAuthorizationServer
    public static class OAuth2Config extends AuthorizationServerConfigurerAdapter implements EnvironmentAware {

        private static final String ENV_OAUTH = "authentication.oauth.";
        private static final String PROP_CLIENTID = "clientid";
        private static final String PROP_SECRET = "secret";
        private static final String PROP_TOKEN_VALIDITY_SECONDS = "tokenValidityInSeconds";

        private RelaxedPropertyResolver propertyResolver;

        @Inject
        private AuthenticationManager authenticationManager;

        @Inject
        private JwtAccessTokenConverter jwtAccessTokenConverter;

        @Inject
        private JwtTokenStore jwtTokenStore;

        @Inject
        private UserDetailsService userDetailsService;

        @Override
        public void setEnvironment(Environment environment) {
            this.propertyResolver = new RelaxedPropertyResolver(environment, ENV_OAUTH);
        }

        @Bean
        @Primary
        public DefaultTokenServices tokenServices() {
            DefaultTokenServices tokenServices = new DefaultTokenServices();
            tokenServices.setSupportRefreshToken(true);
            tokenServices.setTokenStore(jwtTokenStore);
            tokenServices.setAuthenticationManager(authenticationManager);
            return tokenServices;
        }


        @Override
        public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
            endpoints.authenticationManager(authenticationManager).tokenStore(jwtTokenStore).accessTokenConverter(
                    jwtAccessTokenConverter).userDetailsService(userDetailsService);
        }

        @Override
        public void configure(AuthorizationServerSecurityConfigurer oauthServer)
                throws Exception {
            oauthServer.tokenKeyAccess("permitAll()").checkTokenAccess(
                    "isAuthenticated()");
        }

        @Override
        public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
            clients.inMemory()
                    .withClient(propertyResolver.getProperty(PROP_CLIENTID))
                    .scopes("read", "write")
                    .authorities(AuthoritiesConstants.ADMIN, AuthoritiesConstants.USER)
                    .authorizedGrantTypes("authorization_code", "refresh_token", "password")
                    .secret(propertyResolver.getProperty(PROP_SECRET))
                    .accessTokenValiditySeconds(propertyResolver.getProperty(PROP_TOKEN_VALIDITY_SECONDS, Integer.class, 1800));
        }
    }

    @Configuration
    @Order(-10)
    protected static class WebSecurityConfig extends WebSecurityConfigurerAdapter {

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http
                    .formLogin().loginPage("/login").permitAll()
                    .and()
                    .requestMatchers().antMatchers("/login", "/oauth/authorize", "/oauth/confirm_access")
                    .and()
                    .authorizeRequests().anyRequest().authenticated();
        }

        @Bean
        @Override
        public AuthenticationManager authenticationManagerBean() throws Exception {
            return super.authenticationManagerBean();
        }

        @Bean
        @Override
        public UserDetailsService userDetailsServiceBean() throws Exception {
            return super.userDetailsServiceBean();
        }
    }

    @Configuration
    protected static class AuthenticationConfiguration extends
            GlobalAuthenticationConfigurerAdapter {

        @Override
        public void init(AuthenticationManagerBuilder auth) throws Exception {
            auth
                    .ldapAuthentication()
                    .userDnPatterns("uid={0},ou=people")
                    .groupSearchBase("ou=groups")
                    .contextSource().ldif("classpath:test-server.ldif");
        }
    }
}

虽然刷新令牌与spring-security-oauth2的2.0.6版一起工作正常,但它不再适用于版本2.0.7.如此处所述,应该设置AuthenticationManager在刷新期间尝试获取新访问令牌时使用.

据我所知,这与spring-security-oauth2 的以下变化有关.

遗憾的是,我无法正确设置它.

org.springframework.security.oauth2.provider.token.DefaultTokenServices#setAuthenticationManager

被调用并获得AuthenticationManager注入.我不确定我LdapUserDetailsService是怎么理解这是怎么注入的.我唯一看到的是,PreAuthenticatedAuthenticationProvider在令牌刷新调用期间尝试重新验证用户时将调用它.

有人可以告诉我如何做到这一点吗？

ps:我得到的例外情况如下:

p.PreAuthenticatedAuthenticationProvider : PreAuthenticated authentication request: org.springframework.security.web.authentication.preauth.PreAuthenticatedAuthenticationToken@5775: Principal: org.springframework.security.authentication.UsernamePasswordAuthenticationToken@441d5545: Principal: bob; Credentials: [PROTECTED]; Authenticated: true; Details: null; Granted Authorities: ROLE_USER; Credentials: [PROTECTED]; Authenticated: true; Details: null; Granted Authorities: ROLE_USER
o.s.s.o.provider.endpoint.TokenEndpoint  : Handling error: IllegalStateException, UserDetailsService is required.

Answer 1

当我使用自定义JWT令牌AuthenticationProvider而不是UserDetailsService用于解决登录身份验证的实现来实现OAuth2服务器时，我遇到了类似的问题。

但是最近我发现，如果您希望refresh_token正常工作，Spring引发的错误是正确的。对于一个AuthenticationProvider实现，不可能用刷新令牌refresh_token，因为在这种实现中，您必须确定密码是否正确，但是刷新令牌没有该信息。但是，UserDetailsService与密码无关。

2.0.6版本的spring-security-oauth2工作原理是，因为从不检查用户授权，仅检查刷新令牌是否有效（用私钥签名），但是，如果用户在首次登录后从系统中删除，则使用刷新令牌删除的用户将拥有无限时间访问您的系统，这是一个很大的安全问题。

看看我用这个报告的问题：https : //github.com/spring-projects/spring-security-oauth/issues/813

Answer 2

根据 Dave Syer 的建议，我创建了一个自定义LdapUserDetailsService. 可以在以下标签下找到工作解决方案。
