由于“未知资源"，无法通过keycloak-admin-client将用户添加到Keycloak. [英] Failed adding user by keycloak-admin-client to Keycloak due to "unknown resource"

问题描述

我尝试在如下所示的Java代码中使用keycloak-admin-client，然后出现异常.从例外情况来看，即使在到达Keycloak之前，它似乎也未能构造API URL.有人知道为什么会这样吗?

I tried to use keycloak-admin-client in Java code like below, and then I got exceptions. From the exceptions, it looks like that it failed in constructing the API URL, even before reaching Keycloak. Does anybody have idea why this happened?

我正在docker容器中运行Keycloak并暴露了端口8078.

I am running Keycloak inside a docker container and exposed port 8078.

public static void main(String ... args) {
        Keycloak kc = KeycloakBuilder.builder()
                .serverUrl("http://localhost:8078/auth")
                .realm("master")
                .username("admin")
                .password("admin")
                .clientId("admin-cli")
                .resteasyClient(new ResteasyClientBuilder().connectionPoolSize(10).build())
                .build();
        CredentialRepresentation credential = new CredentialRepresentation();
        credential.setType(CredentialRepresentation.PASSWORD);
        credential.setValue("test123");
        UserRepresentation user = new UserRepresentation();
        user.setUsername("testuser");
        user.setFirstName("Test");
        user.setLastName("User");
        user.setEnabled(true);
        user.setCredentials(Arrays.asList(credential));
        kc.realm("master").users().create(user);
}

推荐答案

Caused by: java.lang.NoSuchMethodError: javax.ws.rs.core.UriBuilder.resolveTemplates(Ljava/util/Map;)Ljavax/ws/rs/core/UriBuilder;    

此错误通常表明您在路径上有2个版本的类.
如果您使用像Maven这样的依赖框架，则可以验证继承关系中是否包含正确的库
此类-"javax.ws.rs.core.UriBuilder"

This error usually indicates you have 2 versions of the class on the path.
If you use a dependency framework like Maven, you can verify the correct libraries are included in the heirarchy
This class - "javax.ws.rs.core.UriBuilder"
