Spring 类型为'的必需bean；java.security.KeyPair'；找不到

我正在尝试按照的spring文档来实现AuthorizationServer，但遇到了以下问题：

1.8.1配置授权服务器以使用JWKs 和 1.8.2添加JWK集URI端点

根据此处描述的信息，我将此代码添加到我的

授权服务器ConfigureRadapter

：

@EnableAuthorizationServer
@Configuration
public class JwkSetConfiguration extends AuthorizationServerConfigurerAdapter {

    AuthenticationManager authenticationManager;
    KeyPair keyPair;

    public JwkSetConfiguration(AuthenticationConfiguration authenticationConfiguration,
            KeyPair keyPair) throws Exception {

        this.authenticationManager = authenticationConfiguration.getAuthenticationManager();
        this.keyPair = keyPair;
    }

    // ... client configuration, etc.

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        // @formatter:off
        endpoints
            .authenticationManager(this.authenticationManager)
            .accessTokenConverter(accessTokenConverter())
            .tokenStore(tokenStore());
        // @formatter:on
    }

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

    @Bean
    public JwtAccessTokenConverter accessTokenConverter() {
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
        converter.setKeyPair(this.keyPair);
        return converter;
    }
}

@Autowired
private KeyPair keyPair;

@Bean
public KeyPair keyPairBean() throws NoSuchAlgorithmException {
  KeyPairGenerator gen = KeyPairGenerator.getInstance("RSA");
  gen.initialize(2048);
  KeyPair keyPair = gen.generateKeyPair();
  return keyPair;
}

并将这两个类添加到我的项目中：

@FrameworkEndpoint
class JwkSetEndpoint {
    KeyPair keyPair;

    public JwkSetEndpoint(KeyPair keyPair) {
        this.keyPair = keyPair;
    }

    @GetMapping("/.well-known/jwks.json")
    @ResponseBody
    public Map<String, Object> getKey() {
        RSAPublicKey publicKey = (RSAPublicKey) this.keyPair.getPublic();
        RSAKey key = new RSAKey.Builder(publicKey).build();
        return new JWKSet(key).toJSONObject();
    }
}

所有内容都已编译，没有错误，但当我尝试执行应用程序时，收到以下消息：

***************************
APPLICATION FAILED TO START

Description:

Parameter 1 of constructor in oauth.server.Server required a bean of type 'java.security.KeyPair' that could not be found.

The injection point has the following annotations:
        - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'java.security.KeyPair' in your configuration.

如何定义运行应用程序所需的“java.security.KeyPair”bean

注：my

AuthorizationServerConfigurerAdapter的完整代码为：

@Import(AuthorizationServerEndpointsConfiguration.class)
@Configuration
public class Server extends AuthorizationServerConfigurerAdapter {
    private AuthenticationManager authenticationManager;

    private KeyPair keyPair;

    public Server(AuthenticationConfiguration authenticationConfiguration, KeyPair keyPair) throws Exception {
        this.authenticationManager = authenticationConfiguration.getAuthenticationManager();
        this.keyPair = keyPair;
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return PasswordEncoderFactories.createDelegatingPasswordEncoder();
    }

    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients
            .inMemory()
                .withClient("first-client")
                .secret(passwordEncoder().encode("noonewilleverguess"))
                .scopes("resource:read")
                .authorizedGrantTypes("authorization_code")
                .redirectUris("http://localhost:8080/oauth/login/client-app");
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        endpoints
            .authenticationManager(this.authenticationManager)
            .accessTokenConverter(accessTokenConverter())
            .tokenStore(tokenStore());
    }

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

    @Bean
    public JwtAccessTokenConverter accessTokenConverter() {
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
        converter.setKeyPair(this.keyPair);
        return converter;
    }
}

我设法解决了这个问题，将这个bean添加到我的类
服务器中
：

@EnableAuthorizationServer
@Configuration
public class JwkSetConfiguration extends AuthorizationServerConfigurerAdapter {

    AuthenticationManager authenticationManager;
    KeyPair keyPair;

    public JwkSetConfiguration(AuthenticationConfiguration authenticationConfiguration,
            KeyPair keyPair) throws Exception {

        this.authenticationManager = authenticationConfiguration.getAuthenticationManager();
        this.keyPair = keyPair;
    }

    // ... client configuration, etc.

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        // @formatter:off
        endpoints
            .authenticationManager(this.authenticationManager)
            .accessTokenConverter(accessTokenConverter())
            .tokenStore(tokenStore());
        // @formatter:on
    }

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

    @Bean
    public JwtAccessTokenConverter accessTokenConverter() {
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
        converter.setKeyPair(this.keyPair);
        return converter;
    }
}

@Autowired
private KeyPair keyPair;

@Bean
public KeyPair keyPairBean() throws NoSuchAlgorithmException {
  KeyPairGenerator gen = KeyPairGenerator.getInstance("RSA");
  gen.initialize(2048);
  KeyPair keyPair = gen.generateKeyPair();
  return keyPair;
}

您的pom.xml是什么样子的？我更新了问题以包含它。它告诉您缺少什么。您没有注册KeyPair类型的bean。你需要有一个使用DI的经验。查看您的密码编码器，对密钥对执行相同的操作，并提供一个bean。否则SpringDI无法在需要时为KeyPair对象容器提供服务。它与PasswordEncoder不同。不能只
返回newkeypair（）
，因为它需要公钥和私钥作为参数（我可以从中获取这些参数）。我不知道有没有像密码编码器那样的钥匙对工厂。
