我在用着keycloak 3.4 and spring boot开发一个网络应用程序。
我使用 Active Directory 作为用户联合来检索所有用户信息。
但要在我的网络应用程序中使用这些信息，我想我必须将它们保存在“local-webapp”数据库中。
那么用户登录后，如何将它们保存到数据库中呢？
我正在考虑一个scenario比如：“我有一个对象 A，它引用用户 B，所以我必须在它们之间建立关系。所以我添加一个外键。”
在这种情况下，我需要让用户访问我的数据库。不？
EDIT
为了避免将所有用户保存在我的数据库上，我尝试使用管理员 API，因此我在控制器中添加了以下代码。
我还创建了另一个客户端，名为Test为了获得所有用户，这样我可以使用client-id and client-secret.或者有没有办法使用JWT使用管理 API？
客户端：
Keycloak keycloak2 = KeycloakBuilder.builder()
.serverUrl("http://localhost:8080/auth/admin/realms/MYREALM/users")
.realm("MYREALMM")
.username("u.user")
.password("password")
.clientId("Test")
.clientSecret("cade3034-6ee1-4b18-8627-2df9a315cf3d")
.resteasyClient(new ResteasyClientBuilder().connectionPoolSize(20).build())
.build();
RealmRepresentation realm2 = keycloak2.realm("MYREALMM").toRepresentation();
错误是：
2018-02-05 12:33:06.638 ERROR 16975 --- [nio-8080-exec-7] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Handler dispatch failed; nested exception is java.lang.Error: Unresolved compilation problem:
The method realm(String) is undefined for the type AccessTokenResponse
] with root cause
java.lang.Error: Unresolved compilation problem:
The method realm(String) is undefined for the type AccessTokenResponse
我哪里做错了？
EDIT 2
我也尝试过这个：
@Autowired
private HttpServletRequest request;
public ResponseEntity listUsers() {
KeycloakAuthenticationToken token = (KeycloakAuthenticationToken) request.getUserPrincipal();
KeycloakPrincipal principal=(KeycloakPrincipal)token.getPrincipal();
KeycloakSecurityContext session = principal.getKeycloakSecurityContext();
Keycloak keycloak = KeycloakBuilder.builder()
.serverUrl("http://localhost:8080/auth")
.realm("MYREALMM")
.authorization(session.getToken().getAuthorization().toString())
.resteasyClient(new ResteasyClientBuilder().connectionPoolSize(20).build())
.build();
RealmResource r = keycloak.realm("MYREALMM");
List<org.keycloak.representations.idm.UserRepresentation> list = keycloak.realm("MYREALMM").users().list();
return ResponseEntity.ok(list);
但授权始终是null.
Why?

为了访问整个用户列表，您必须验证已登录的用户至少包含view-users角色来自realm-management客户，请参阅这个答案 https://stackoverflow.com/a/46558530/1199132我前段时间写过。一旦用户拥有此角色，她检索到的 JWT 将共同包含该角色。
从你的评论中我可以推断，你似乎缺乏一些关于Authorization标头。用户登录后，她会从 keycloak 获取签名的 JWT，因此领域中的每个客户端都可以信任它，而无需询问 Keycloak。该 JWT 包含访问令牌，稍后在Authorization每个用户请求的标头，前缀为Bearer关键字（参见基于令牌的身份验证 in https://auth0.com/blog/cookies-vs-tokens-definitive-guide/ https://auth0.com/blog/cookies-vs-tokens-definitive-guide/).
因此，当用户向您的应用程序发出请求以查看用户列表时，她的访问令牌包含view-users角色已经进入请求标头。不必手动解析它，而是自己创建另一个请求来访问 Keycloak 用户端点并附加它（就像您似乎正在做的那样）KeycloakBuilder），Keycloak Spring Security 适配器已经提供了KeycloakRestTemplate类，它能够为当前用户执行对另一个服务的请求：
安全配置.java
@Configuration
@EnableWebSecurity
@ComponentScan(basePackageClasses = KeycloakSecurityComponents.class)
public class SecurityConfig extends KeycloakWebSecurityConfigurerAdapter {
...
@Autowired
public KeycloakClientRequestFactory keycloakClientRequestFactory;
@Bean
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
public KeycloakRestTemplate keycloakRestTemplate() {
return new KeycloakRestTemplate(keycloakClientRequestFactory);
}
...
}
请注意，模板的范围是PROTOTYPE，因此 Spring 将为每个发出的请求使用不同的实例。
然后，自动装配此模板并使用它来发出请求：
@Service
public class UserRetrievalService{
@Autowired
private KeycloakRestTemplate keycloakRestTemplate;
public List<User> getUsers() {
ResponseEntity<User[]> response = keycloakRestTemplate.getForEntity(keycloakUserListEndpoint, User[].class);
return Arrays.asList(response.getBody());
}
}
您需要实施自己的User与 keycloak 服务器返回的 JSON 响应相匹配的类。
请注意，当用户不允许访问该列表时，Keycloak 服务器会返回 403 响应代码。您甚至可以在自己之前否认它，使用一些注释，例如：@PreAuthorize("hasRole('VIEW_USERS')").
最后但并非最不重要的一点是，我认为@dchrzascik 的回答很明确。总而言之，我想说实际上还有另一种方法可以避免每次从 keycloak 服务器检索整个用户列表或将用户存储在应用程序数据库中：您实际上可以缓存它们，这样您就可以更新该缓存从您的应用程序进行用户管理。
EDIT
我已经实现了一个示例项目来展示如何获取完整的用户列表，并将其上传到Github https://github.com/xtremebiker/keycloak-user-retrieval。它是为机密客户端配置的（当使用公共客户端时，应从 application.properties 中删除机密）。
