我正在使用 Spring Boot 和 Keycloak 开发网络应用程序。然后我写了一个计划任务，我在其中使用 KeycloakRestTemplate 向另一个应用程序询问一些数据，如下所示:

    @Override
    @Scheduled(cron="0 50 09 * * MON-FRI")
    public void concludiCommessa() {

        try {
            FDto[] ftts = new ObjectMapper().readValue(restTemplate.getForEntity(URI.create(MY_URL), String.class).getBody(), FDto[].class);

             ..............................
            }
        } catch (RestClientException | IOException e) {
        }
    }

如果我在服务器上运行它会出现以下错误:

2018-04-18 09:50:00.067 ERROR 2503 --- [pool-8-thread-1] o.s.s.s.TaskUtils$LoggingErrorHandler    : Unexpected error occurred in scheduled task.

为什么？

如果我使用的是异步任务，我该如何传递主体？

编辑这是我的安全配置:

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) {
    auth.authenticationProvider(keycloakAuthenticationProvider());
}

@Bean
@Override
protected SessionAuthenticationStrategy sessionAuthenticationStrategy() {
    return new RegisterSessionAuthenticationStrategy(new SessionRegistryImpl());
}

@Bean
@Scope(ConfigurableBeanFactory.SCOPE_SINGLETON)
public KeycloakRestTemplate keycloakRestTemplate() {
    return new KeycloakRestTemplate(keycloakClientRequestFactory);
}

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

编辑 这是我的 key 斗篷属性:

#######################################
#             KEYCLOAK                #
#######################################
keycloak.realm=MY_REALM
keycloak.auth-server-url=MY_URL/auth
keycloak.ssl-required=external
keycloak.resource=EdilGest
keycloak.credentials.jwt.client-key-password=PWD
keycloak.credentials.jwt.client-keystore-file=classpath:CLIENT.jks
keycloak.credentials.jwt.client-keystore-password=PWD
keycloak.use-resource-role-mappings=true
keycloak.principal-attribute=preferred_username

编辑:

我正在尝试使用服务帐户，但目前无法使用...阅读此处:https://www.keycloak.org/docs/latest/server_admin/index.html#_service_accounts

我必须发送如下请求:

POST /auth/realms/demo/protocol/openid-connect/token
    Authorization: Basic cHJvZHVjdC1zYS1jbGllbnQ6cGFzc3dvcmQ=
    Content-Type: application/x-www-form-urlencoded

    grant_type=client_credentials

到 keycloak，但我如何使用 Spring 发送它？以及如何设置 jks 而不是 client 和 secret？

我的安全配置

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled=true)
@KeycloakConfiguration
public class SecurityConfig extends KeycloakWebSecurityConfigurerAdapter {  

    @Autowired
    public KeycloakClientRequestFactory keycloakClientRequestFactory;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        super.configure(http);

        http
            .httpBasic()
            .disable();

        http
        .authorizeRequests()
            .antMatchers("/webjars/**").permitAll()
            .antMatchers("/resources/**").permitAll()
            .anyRequest().hasAuthority("......")
        .and()
        .logout()
            .logoutUrl("/logout")
            .logoutRequestMatcher(new AntPathRequestMatcher("/logout", "GET"))
            .permitAll()
            .logoutSuccessUrl(mux)
            .invalidateHttpSession(true);

    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) {
        auth.authenticationProvider(keycloakAuthenticationProvider());
    }

    @Bean
    @Override
    protected SessionAuthenticationStrategy sessionAuthenticationStrategy() {
        return new RegisterSessionAuthenticationStrategy(new SessionRegistryImpl());
    }

    @Bean
    @Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
    public KeycloakRestTemplate keycloakRestTemplate() {
        return new KeycloakRestTemplate(keycloakClientRequestFactory);
    }

    @Bean
    public KeycloakConfigResolver 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
    public void configure(WebSecurity web) throws Exception {
        web
           .ignoring()
           .antMatchers("/resources/**", "/static/**", "/css/**", "/js/**", "/images/**", "/webjars/**");
    }

}

编辑 3这是我尝试过的...它不起作用..我有同样的错误:java.lang.IllegalStateException: Cannot set authorization header because there is no authenticated principal

KeyStoreKeyFactory keyStoreKeyFactory = new KeyStoreKeyFactory(new ClassPathResource("EdilGest.jks"), "EdilGest".toCharArray());

JWTClientCredentialsProvider jwtClientCredentialsProvider = new JWTClientCredentialsProvider();
jwtClientCredentialsProvider.setupKeyPair(keyStoreKeyFactory.getKeyPair("MyClient"));
String token = jwtClientCredentialsProvider.createSignedRequestToken("MyClient", "http://myKeycloak/auth/");

String data = "grant_type=client_credentials" ;
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
headers.add(HttpHeaders.AUTHORIZATION, "Bearer " +token);

HttpEntity<String> requestEntity = new HttpEntity<String>(data, headers);
String ftt = keycloakRestTemplate.exchange(URI.create(MyUrl), HttpMethod.POST, requestEntity, String.class).getBody();

我做错了什么？

最佳答案

如果你想通过spring发送如下请求

POST /auth/realms/demo/protocol/openid-connect/token
    Authorization: Basic cHJvZHVjdC1zYS1jbGllbnQ6cGFzc3dvcmQ=
    Content-Type: application/x-www-form-urlencoded

    grant_type=client_credentials

你需要的是类似的东西

RestTemplate template = new RestTemplate();
String uri = "https://host:port/auth/realms/demo/protocol/openid-connect/token";
String data = "grant_type=client_credentials" ;
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
headers.add(HttpHeaders.AUTHORIZATION, "Basic " + Base64Utils.encodeToString("clientId:clientSecret".getBytes()));
HttpEntity<String> requestEntity = new HttpEntity<String>(data, headers);

ResponseEntity<JsonNode> result = template.exchange(uri, HttpMethod.POST, requestEntity, JsonNode.class);
JsonNode jn = result.getBody();
String access_token = jn.get("access_token").asText();

用实际值替换clientId和clientSecret。

更新:-

引用您在问题中提到的链接，您可以通过 keycloak 本身生成 jwt 承载 token (客户端访问 token )。获得 jwt token 后，您对资源服务器的后续请求应包含 header 

Authorization: Bearer <jwt bearer token>

在 @Xtreme Biker 关于主题 Keycloak spring security client credential grant 的帖子中，他提供了一些示例代码，或许您可以使用拦截器方法实现此目的。

更多更新:-

根据 keycloak 文档 - https://www.keycloak.org/docs/3.1/securing_apps/topics/oidc/java/java-adapter-config.html

要设置 jks，您应该在 application.properties 文件中具有以下属性。

keycloak.client-keystore-password=PWD
keycloak.client-keystore=classpath:CLIENT.jks
keycloak.client-key-password=PWD

并根据 - https://www.keycloak.org/docs/3.1/securing_apps/topics/oidc/java/spring-security-adapter.html ，一旦您正确设置了 jks，KeycloakRestTemplate 应该能够为您的请求添加正确的身份验证 header 。

更新 3:-

通过后 - https://github.com/keycloak/keycloak-documentation/blob/master/securing_apps/topics/oidc/java/spring-security-adapter.adoc ，我坚信 KeycloakRestTemplate 应该能够将所需的 jwt token 添加到请求的授权 header 中，因为它使用 KeycloakClientRequestFactory 从 KeycloakSecurityContext< 获取 token 字符串.

请尝试添加本文档中建议的所有配置，如所有过滤器 bean 配置

@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;
    }

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

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

并确保您在 application.properties 文件中提供所有必需的属性。

由于您正在从本质上可能是异步的计划任务中发出请求，因此您可能必须更改 SecurityConfig 的构造函数中的策略，而不是 ThreadLocal SecurityContext 使用了 InheritableThreadLocal，它在生成子线程时传递此信息。 

public SecurityConfig ( KeycloakClientRequestFactory keycloakClientRequestFactory ) {
         this.keycloakClientRequestFactory = keycloakClientRequestFactory ;

         // to use principal and authentication together with @ async
         SecurityContextHolder.setStrategyName ( SecurityContextHolder.MODE_INHERITABLETHREADLOCAL ) ;

     }

希望这能以某种方式帮助您解决问题。
