Keycloak：无法在 Spring Boot 应用程序中加载 URL

我目前正在尝试开发一个使用 keycloak 保护的 Spring Boot Rest Api。

当我尝试调用必须识别用户的 api 时，出现错误。

错误信息如下：

我不知道什么Failed to load URLs from方法。当我单击链接并显示配置文件时，我可以访问这一侧。

Setup

钥匙斗篷：

Keycloak 服务器位于网络中，因此没有本地主机。

我创建了一个领域（测试领域）
我创建了一个客户端（测试客户端）
我创建了一个用户（测试用户）
我在客户端（ADMIN）创建了一个角色
我已将角色（ADMIN）分配给用户（测试用户）

客户端的客户端协议是openid-connect访问类型是confidental.

春季启动：

Spring Boot Rest 应用程序在 localhost:8080 上运行。

我添加在applications.properties以下 keycloak 配置。

keycloak.realm={{test-realm}}
keycloak.auth-server-url = https://{{keycloakserver}}.de/auth
keycloak.resource = {{test-client}}
keycloak.ssl-required=external
keycloak.bearer-only=true
keycloak.principal-attribute=preferred_username
keycloak.use-resource-role-mappings = true

为了确保测试用户只能访问一个 api 调用，我使用了以下配置。

 @Override
    protected void configure(HttpSecurity http) throws Exception {
        super.configure(http);
        http.authorizeRequests()
                .antMatchers("/getTest")
                .hasRole("ADMIN")
                .anyRequest()
                .authenticated();
    }

Tests

当我打电话时http://localhost:8080/getTest与邮递员我得到了正确的401 Unauthorized.

然后我调用了相同的 URLAuthorization以及登录的访问令牌test-user.

通过第二次调用，我收到上面的错误消息。

有人知道这件事吗？ 如果我遗漏了您需要知道的配置值，请询问。

感谢您的帮助。

Edit:

@Configuration
@KeycloakConfiguration
public class SecurityConfig extends KeycloakWebSecurityConfigurerAdapter {

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        KeycloakAuthenticationProvider keycloakAuthenticationProvider = keycloakAuthenticationProvider();
        auth.authenticationProvider(keycloakAuthenticationProvider);
    }

                .anyRequest()
                .authenticated();
    }
}

自定义KeycloakSpringBootConfigResolver：

import org.keycloak.adapters.KeycloakDeployment;
import org.keycloak.adapters.KeycloakDeploymentBuilder;
import org.keycloak.adapters.spi.HttpFacade;
import org.keycloak.adapters.springboot.KeycloakSpringBootConfigResolver;
import org.keycloak.adapters.springboot.KeycloakSpringBootProperties;
import org.springframework.context.annotation.Configuration;

/**
 * Created by johannes on 10.04.20 for test App.*/
@Configuration
public class CustomKeycloakSpringBootConfigResolver extends KeycloakSpringBootConfigResolver {
        private final KeycloakDeployment keycloakDeployment;
    public CustomKeycloakSpringBootConfigResolver(KeycloakSpringBootProperties properties) {

        keycloakDeployment = KeycloakDeploymentBuilder.build(properties);
    }

    @Override
    public KeycloakDeployment resolve(HttpFacade.Request facade) {
        return keycloakDeployment;
    }
}

TestController.java（这只是测试 getter）：

  @GetMapping("/getTest")
    public @ResponseBody ResponseEntity getTest() {

        return ResponseEntity.status(ResponseValues.ITEMDELETEFAILED.getResponseCode()).body(ResponseValues.ITEMDELETEFAILED.getResponseMessage());

    }

请求是通过邮递员发出的，这是代码：

curl --location --request GET 'http://localhost:8080/getTest' \
--header 'Authorization: Bearer eyJhbGciOiJSUzI1NiIsInR5cCIgOiAiSldUI...' \
--header 'Cookie: JSESSIONID=41E8E82178FA181817...'

我也有同样的问题，我尝试在google、stackoverflow等上寻找答案......

最后，我抓住了线索，要让它发挥作用，只需去除path的keycloak.auth-server-url as http://192.168.0.119:8080代替http://192.168.0.119:8080/auth或者是其他东西.

...   : Loaded URLs from http://192.168.0.119:8080/realms/spmia-realm/.well-known/openid-configuration

keycloak.ssl-required=external
