Question

我正在尝试显示userEmail（）或者在我们的领域中显示有关用户的所有信息。

我正在尝试调用此方法： -

@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());


    }

但它失败了，给我这个错误： - |

我想知道是否有正确的方式来显示有关用户的信息，甚至是否显示我们在我们领域的用户！

感谢您的帮助。

为了让它更加明显，我会重复在评论中找到的Sébastien的Blanc答案。

keycloak adapter和client依赖项不是同一个版本，因此Jackson获得了一些无法映射到类的字段（在这种情况下，字段notBefore不可用于UserRepresentation类。）。

所以在你的pom.xml中，确保依赖是相同的。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>

使用keycloak显示用户电子邮件Admin Client无法正常工作（UnrecognizedPropertyException）
