使用 keycloak - JWT 令牌保护 Spring Boot 服务

nej*_*asa 2 jwt spring-boot bearer-token keycloak keycloak-services

所以,我使用 keycloak 来保护我的服务。客户端应用程序从 keycloak 服务器获取访问令牌,并使用它来保护对 Spring boot 应用程序的访问。我已经使用仅持有者访问类型使用 keycloak 属性配置了我的 Spring Boot 应用程序:

keycloak.realm = master
keycloak.realmKey = ...
keycloak.auth-server-url = http://localhost:8080/auth
keycloak.ssl-required = external
keycloak.resource = boot-app
keycloak.bearer-only = true
keycloak.cors = true

Spring Boot keycloak 启动器:

<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-spring-boot-starter</artifactId>
</dependency>

并配置 KeycloakWebSecurityConfigurerAdapter:

@Configuration
@ComponentScan(basePackageClasses = KeycloakSecurityComponents.class)
public class KeycloakSecurityConfig extends KeycloakWebSecurityConfigurerAdapter
{
  /**
   * Registers the KeycloakAuthenticationProvider with the authentication manager.
   */
  @Autowired
  public void configureGlobal(final AuthenticationManagerBuilder auth) throws Exception
  {
    final KeycloakAuthenticationProvider keycloakAuthenticationProvider = keycloakAuthenticationProvider();
    keycloakAuthenticationProvider.setGrantedAuthoritiesMapper(new SimpleAuthorityMapper());
    auth.authenticationProvider(keycloakAuthenticationProvider);
  }

  @Bean
  public KeycloakConfigResolver keycloakConfigResolver()
  {
    return new KeycloakSpringBootConfigResolver();
  }

  /**
   * Defines the session authentication strategy.
   */
  @Bean
  @Override
  protected SessionAuthenticationStrategy sessionAuthenticationStrategy()
  {
    return new RegisterSessionAuthenticationStrategy(new SessionRegistryImpl());
  }

  @Override
  protected void configure(final HttpSecurity http) throws Exception
  {
    super.configure(http);
    http
        .authorizeRequests()
        .antMatchers(
            "/v2/api-docs",
            "/configuration/ui",
            "/swagger-resources",
            "/configuration/security",
            "/swagger-ui.html",
            "/webjars/**",
            "/swagger-resources/configuration/ui",
            "/swagge??r-ui.html",
            "/swagger-resources/configuration/security").permitAll()
        .antMatchers("/*").hasRole("user")
        .anyRequest().authenticated();
  }

现在,一切正常。我的问题是:不记名令牌是 JWT 令牌,您需要对其进行解码(并验证访问)的是公钥,即

keycloak.realmKey

为什么需要其他设置,特别是:

keycloak.auth-server-url

公钥不是你需要的一切吗?

事实上,bearer-only您可能想知道为什么需要 KC URL,但由于一些 KC 版本realmKey不再是强制性的,因为我们使用密钥轮换。这意味着您的应用程序将使用该auth-server-url属性从 KC 服务器动态检索公钥。
