使用spring boot（安全性）和KeyCloak启用角色身份验证？

Question

我在试着做一件简单的事。

接下来是设置我的keycloak信息（realm,role,user）https://medium.com/@bcarunmail/securing-rest-api-using-keycloak-and-spring-oauth2-6ddf3a1efcc2

所以，

我基本上用一个客户机、一个具有特定角色“user”的用户来设置我的keycloak，并像这样配置它：

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

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

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

    @Bean
    public FilterRegistrationBean keycloakAuthenticationProcessingFilterRegistrationBean(
            KeycloakAuthenticationProcessingFilter filter) {
        FilterRegistrationBean registrationBean = new FilterRegistrationBean(filter);
        registrationBean.setEnabled(false);
        return registrationBean;
    }

    @Bean
    public FilterRegistrationBean keycloakPreAuthActionsFilterRegistrationBean(
            KeycloakPreAuthActionsFilter filter) {
        FilterRegistrationBean registrationBean = new FilterRegistrationBean(filter);
        registrationBean.setEnabled(false);
        return registrationBean;
    }


    @Override
    protected void configure(HttpSecurity http) throws Exception
    {
        super.configure(http);
        http
                .authorizeRequests()
                .antMatchers("/user/*").hasRole("admin")
                .antMatchers("/admin*").hasRole("user")

    }
}

.anyRequest().permitAll();

但当我把这作为最后一条规则

 .anyRequest().denyAll();

我总是得到403。

我发现了这个：

o.k.a.BearerTokenRequestAuthenticator    : Found [1] values in authorization header, selecting the first value for Bearer.

我请求访问令牌发送：

client_id -> my client from keycloak
username -> my user from keycloak
password -> my password from keycloak
grant_type -> password
client_secret -> from keycloak

我得到一个令牌，然后我用它来请求我的应用程序EndoInt。无论我使用什么endpoint（角色用户endpoint或角色管理员endpoint），我的请求总是有效的。

在我的房产中，我有这样的东西：

keycloak:
  auth-server-url: http://localhost:8080/auth/
  resource: users-api
  credentials:
    secret : my-secret
  use-resource-role-mappings : true
  realm: my-realm
  realmKey:  my-key
  public-client: true
  principal-attribute: preferred_username
  bearer-only: true

你知道如何在这种情况下实际启用这些角色吗？

我必须配置客户端才能使用JWT吗？有什么想法吗？

@Secured("admin")
@PreAuthorize("hasAnyAuthority('admin')")

"realm_access": {
    "roles": [
      "offline_access",
      "admin",
      "uma_authorization"
    ]
  },
  "resource_access": {
    "account": {
      "roles": [
        "manage-account",
        "manage-account-links",
        "view-profile"
      ]
    }
  },

Answer 1

在调试堆栈中：我看到您正在调用/api/user/123，而在您的安全配置中，您正在保护/user/*，这是不一样的，将您的安全性更改为：

.antMatchers("/api/user/*").hasRole("user")
                .antMatchers("/api/admin*").hasRole("admin")

P.S：您不需要注册KeycloakAuthenticationProcessingFilter和KeycloakPreAuthActionsFilter
