Oauth2 Client Credentials Flow + Spring Boot2 throwing There is no PasswordEncoder mapped > for the id "null" error

Question

我正在升级我现有的 Client Credentials Oauth2 以使用 Spring Boot 2。
授权服务器使用基本身份验证，Base64 编码为(client:secret)
我正在使用 RedisTokenStore 来存储令牌。

我正在努力使用新升级进行 Oauth2 配置所需的配置。我找不到指向客户凭证流程的正确文档。
随着 Spring 5 Security 的更新，密码编码失败，我得到：-

java.lang.IllegalArgumentException: 没有映射 PasswordEncoder 对于 id "null" 错误

以下是我的配置：-

@Configuration
public class WebConfiguration extends WebSecurityConfigurerAdapter {

        @Override
        protected void configure(HttpSecurity http) throws Exception {
                http.
                        csrf().disable().
                        authorizeRequests().antMatchers(HttpMethod.OPTIONS, "/oauth/token").permitAll();
        }

}

AuthorizationServer 和 ResourceServer

@Configuration
@EnableAuthorizationServer
public class Oauth2Configuration extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private ClientDetailsService clientDetailsService;

    @Autowired
    private JedisConnectionFactory jedisConnFactory;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.withClientDetails(clientDetailsService);
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.tokenStore(tokenStore());
        super.configure(endpoints);
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security.passwordEncoder(passwordEncoder());
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        String idForEncode = "bcrypt";
        Map<String, PasswordEncoder> encoderMap = new HashMap<>();
        encoderMap.put(idForEncode, new BCryptPasswordEncoder());
        return new DelegatingPasswordEncoder(idForEncode, encoderMap);
    }

    @Bean
    public TokenStore tokenStore() {
        return new Oauth2TokenStore(jedisConnFactory);
    }

    @Configuration
    @EnableResourceServer
    protected static class ResourceServer extends ResourceServerConfigurerAdapter {

        @Override
        public void configure(HttpSecurity http) throws Exception {
            http
                    .authorizeRequests()
                    .antMatchers("/verify_token").authenticated()
                    .antMatchers(HttpMethod.OPTIONS, "/**").permitAll()
                    .antMatchers(HttpMethod.GET, "/info").permitAll()
                    .antMatchers(HttpMethod.GET, "/health").permitAll();
        }
    }
}

RedisTokenStore

public class Oauth2TokenStore extends RedisTokenStore {
    @Autowired
    private ClientDetailsService clientDetailsService;


    public Oauth2TokenStore(RedisConnectionFactory connectionFactory) {
        super(connectionFactory);
    }

    @Override
    public void storeAccessToken(OAuth2AccessToken token, OAuth2Authentication authentication) {
        Object principal = authentication.getPrincipal();

        //Principal is consumer key since we only support client credential flow
        String consumerKey = (String) principal;

        //get client detials
        ClientDetails clientDetails = clientDetailsService.loadClientByClientId(consumerKey);


        // Logic to Create JWT
        .
        .
        .
        //Set it to Authentication
        authentication.setDetails(authToken);

       super.storeAccessToken(token, authentication);
    }

    @Override
    public OAuth2Authentication readAuthentication(String token) {
        OAuth2Authentication oAuth2Authentication =  super.readAuthentication(token);
        if (oAuth2Authentication == null) {
            throw new InvalidTokenException("Access token expired");
        }
        return oAuth2Authentication;
    }
}
}

在更新 Spring Security 密码编码后，当我存储在 redis 存储中时，我还需要对令牌进行编码吗？

Answer 1

此错误表示存储的密码没有以密码类型为前缀。

例如，您的散列密码可能类似于：

$2a$10$betZ1XaM8rTUQHwWS.cyIeTKJySBfZsmC3AYxYjwa4fHtr6i/.9oG

但是，Spring Security 现在正在期待：

{bcrypt}$2a$10$betZ1XaM8rTUQHwWS.cyIeTKJySBfZsmC3AYxYjwa4fHtr6i/.9oG

你基本上有two options。首先是使用默认值配置您的DelegatingPasswordEncoder：

@Bean
public PasswordEncoder passwordEncoder() {
    String idForEncode = "bcrypt";
    BCryptPasswordEncoder bcrypt = new BCryptPasswordEncoder();
    Map<String, PasswordEncoder> encoderMap = 
        Collections.singletonMap(idForEncode, bcrypt);
    DelegatingPasswordEncoder delegating =
        new DelegatingPasswordEncoder(idForEncode, encoderMap);
    delegating.setDefaultPasswordEncoderForMatches(bcrypt);
    return delegating;
}

或者第二个是批量升级您的密码存储（以{bcrypt}为前缀）。

我不确定你的 ClientDetailsService 是从哪里来的，但我会开始寻找那里。

更新：不过，这假设您现有的密码是 bcrypted。如果不是，那么您将提供适当的编码器：

@Bean
public PasswordEncoder passwordEncoder() {
    String idForEncode = "bcrypt";
    PasswordEncoder existing = new MyPasswordEncoder();
    PasswordEncoder updated = new BCryptPasswordEncoder();
    Map<String, PasswordEncoder> encoderMap = 
        Collections.singletonMap(idForEncode, updated);
    DelegatingPasswordEncoder delegating =
        new DelegatingPasswordEncoder(idForEncode, encoderMap);
    delegating.setDefaultPasswordEncoderForMatches(existing);
    return delegating;
}
