spring Cloud微服务 security+oauth2认证授权中心自定义令牌增强，并实现登录和退出_spring security实现微服务用户中心

在Spring Cloud微服务架构中，使用Spring Security和OAuth2构建认证授权中心，并实现自定义令牌增强和登录退出的示例代码如下：

@Configuration
@EnableAuthorizationServer
public class AuthServerConfig extends AuthorizationServerConfigurerAdapter {
 
    @Autowired
    private AuthenticationManager authenticationManager;
 
    @Autowired
    private UserDetailsService userDetailsService;
 
    @Autowired
    private DataSource dataSource;
 
    @Autowired
    private TokenStore tokenStore;
 
    @Autowired
    private JwtAccessTokenConverter jwtAccessTokenConverter;
 
    @Autowired
    private CustomTokenEnhancer customTokenEnhancer;
 
    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.jdbc(dataSource);
    }
 
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        TokenEnhancerChain tokenEnhancer = new TokenEnhancerChain();
        tokenEnhancer.setTokenEnhancers(Arrays.asList(customTokenEnhancer, jwtAccessTokenConverter));
 
        endpoints
            .tokenStore(tokenStore)
            .accessTokenConverter(jwtAccessTokenConverter)
            .tokenEnhancer(tokenEnhancer)
            .authenticationManager(authenticationManager)
            .userDetailsService(userDetailsService);
    }
 
    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security.tokenKeyAccess("isAnonymous() || hasAuthority('SCOPE_read')")
            .checkTokenAccess("hasAuthority('SCOPE_read')");
    }
}
 
@Component
public class CustomTokenEnhancer implements TokenEnhancer {
    @Override
    public OAuth2AccessToken enhance(OAuth2AccessToken accessToken, OAuth2Authentication authentication) {
        final Map<String, Object> additionalInfo = new HashMap<>();
        User user = (User) authentication.getPrincipal();
        additionalInfo.put("user_id", user.getUsername());
        ((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(additionalInfo);
        return accessToken;
    }
}
 
@RestController
public class L
