使用 keycloak Admin Client 顯示用戶電子郵件不起作用（UnrecognizedPropertyException）

Question

我正在嘗試顯示 userEmail() 或顯示有關我們領域中用戶的所有信息。

我正在嘗試調用此方法：-

@Test 
    public void displayUser(){

        UsersResource users=kc.realm("SpringBoot").users();
        UserResource user=users.get("b3479699-430b-4cd3-be96-d26db584d207"); //Succeeds, we have the user
        UserRepresentation ur=user.toRepresentation();
        System.out.println(ur.getEmail());


    }

但它失敗了，給了我這個錯誤：-|

javax.ws.rs.client.ResponseProcessingException: javax.ws.rs.ProcessingException: com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "notBefore" (class org.keycloak.representations.idm.UserRepresentation), not marked as ignorable (25 known properties: "disableableCredentialTypes", "enabled", "emailVerified", "origin", "self", "applicationRoles", "createdTimestamp", "clientRoles", "groups", "username", "totp", "id", "email", "federationLink", "serviceAccountClientId", "lastName", "clientConsents", "socialLinks", "realmRoles", "attributes", "firstName", "credentials", "requiredActions", "federatedIdentities", "access"])

我想知道是否有適當的方法來顯示有關用戶的信息甚至顯示我們在我們領域中擁有的用戶！

我感謝您的幫助。

只是為了讓它更明顯，我確實重復了 Sébastien 在評論中找到的 Blanc 答案。

keycloak adapter和client依賴不是同一個版本，所以 Jackson 得到了一些無法映射到類的字段（在這種情況下，字段notBefore在 UserRepresentation 類中不可用）。

所以在你的 pom.xml 中，確保依賴是相同的。 例如：

<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-spring-security-adapter</artifactId>
    <version>3.4.0.Final</version>
</dependency>
<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-admin-client</artifactId>
    <version>3.4.0.Final</version>
</dependency>
