java-如何与使用keycloak提供网页的客户端一起使用计划任务？

2023-08-24 21:12:58

我正在使用Spring Boot和Keycloak开发一个Web应用程序.
然后,我编写了一个计划任务,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) {
        }
    }

如果在服务器上运行它,则会出现以下错误：

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？

如果我正在使用异步任务,如何传递主体？

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();
}

编辑这是我的密钥斗篷属性：

#######################################
#             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…在这里阅读：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

密钥斗篷,但是如何使用Spring发送呢？以及如何设置jks而不是客户端和机密？

    }

}

在这里,我尝试了…它不起作用..我遇到相同的错误：java.lang.IllegalStateException：无法设置授权标头,因为没有经过身份验证的主体

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();

我究竟做错了什么？

解决方法:

默认情况下,SecurityContextHolder使用THREAD_LOCAL策略,因此其他线程不会从其父级继承上下文.
查看MODE_INHERITABLETHREADLOCAL的Javadoc,看看它是否符合您的需求.
