Spring Oauth2. DaoAuthenticationProvider 中未设置密码编码器

我对 Spring Oauth 和 Spring Security 很陌生。我正在尝试在我的项目中使用 client_credentials 流程。现在，我设法使用自己的 CustomDetailsS​​ervice 来从系统中已存在的数据库中获取 client_id 和密码（秘密）。唯一的问题是我无法更改 AuthorizationServer 使用的 DaoAuthenticationProvider 中的密码编码器 - 它默认设置为 PlaintextPasswordEncoder。我无法以它使用 SHAPasswordEncoder 的方式配置它。它始终使用明文编码器。我可能不太了解流程，因为我是 Spring 的新手。

这是我的一些代码（DaoAuthenticationProvider 的配置不起作用）：

安全配置.java

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

private static final String RESOURCE_ID = "restservice";

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/register/**");

}

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

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.authenticationProvider(daoAuthenticationProvider());
}

@Bean
public DaoAuthenticationProvider daoAuthenticationProvider() {
    DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
    daoAuthenticationProvider.setUserDetailsService(userDetailsService());
    daoAuthenticationProvider.setPasswordEncoder(passwordEncoder());
    return daoAuthenticationProvider;
}

@Bean
public PasswordEncoder passwordEncoder() {
    return new ShaPasswordEncoder();
}

@Configuration
@EnableAuthorizationServer
protected static class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private MyCustomClientDetailsService myCustomClientDetailsService;

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

    @Bean
    public ResourceServerTokenServices defaultTokenServices() {
        final DefaultTokenServices defaultTokenServices = new DefaultTokenServices();
        defaultTokenServices.setSupportRefreshToken(true);
        defaultTokenServices.setTokenStore(tokenStore());
        return defaultTokenServices;
    }

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

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

    @Bean
    public MyCustomClientDetailsService detailsService() {
        return new MyCustomClientDetailsService();
    }
}

@Configuration
@EnableResourceServer
protected static class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {

    ...
}
}

以及自定义 ClientDetailsS​​ervice 类：

public class MyCustomClientDetailsService implements ClientDetailsService {

@Autowired
private UserService userService;

@Override
public ClientDetails loadClientByClientId(String clientId) throws ClientRegistrationException {

    User fan = userService.getFan(clientId);

    if (fan == null) {
        throw new NoSuchClientException("No client with requested id: " + clientId);
    } 

    BaseClientDetails details = new BaseClientDetails(clientId, restservice, "write", "client_credentials", "USER");

    details.setClientSecret(fan.getEncodedPassword()); 

    return details;
}
}

从我的 UserService 获取的encodedPassword 始终是一个错误的凭据，因为 DaoAuthenticationProvider 默认设置了 PlaintextPasswordEncoder。

我在那里缺少什么？ 是否可以在用于检查凭据的 DaoAuthenticationProvider 中设置密码编码器？或者我是否必须编写自己的 AuthenticationProvider，以便按照我想要的方式检查它？

我发现问题的解决方案是覆盖configure on AuthorizationServerConfigurerAdapter

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