如何转换<；oauth：授权服务器>；到Java配置？

我相信所有这些都只是使用默认值，我们使用jdbc作为令牌存储，客户机详细信息是默认的变量。看起来我们有一个自定义的userApprovalHandler

<oauth:authorization-server 
    client-details-service-ref="clientDetails"
    token-services-ref="tokenServices"
    user-approval-handler-ref="userApprovalHandler">
    <oauth:client-credentials />
    <oauth:password authentication-manager-ref="authenticationManager"/>
</oauth:authorization-server>

因为这似乎只是一个小片段，如果您能提供一个完整的配置类示例，并提供这些选项，那么java配置应该不会太大。

请在下面找到一个示例代码：-

    @Configuration
    @EnableAuthorizationServer
    public class OAuth2CustomConfig extends
            AuthorizationServerConfigurerAdapter {

        @Autowired
        private AuthenticationManager authenticationManager;

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

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

        @Override
        public void configure(ClientDetailsServiceConfigurer clients)
                throws Exception {
            clients.inMemory()
                    .withClient("xxxx")
                    .secret("xxxxsecret")
                    .authorizedGrantTypes("authorization_code",
                            "refresh_token", "password").scopes("openid");
        }

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

    }

    @Configuration
    @EnableAuthorizationServer
    public class OAuth2CustomConfig extends
            AuthorizationServerConfigurerAdapter {

        @Autowired
        private AuthenticationManager authenticationManager;

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

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

        @Override
        public void configure(ClientDetailsServiceConfigurer clients)
                throws Exception {
            clients.inMemory()
                    .withClient("xxxx")
                    .secret("xxxxsecret")
                    .authorizedGrantTypes("authorization_code",
                            "refresh_token", "password").scopes("openid");
        }

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

    }
