ClassNotFoundException: org.jboss.resteasy.client

Question

尝试使用以下代码创建一个 keycloak 对象以使用 keycloak 注册新用户：

 Keycloak keycloak = KeycloakBuilder.builder()
                            .serverUrl(serverUrl)
                            .realm(realm)
                            .grantType(OAuth2Constants.PASSWORD)
                            .clientId(clientId)
                            .clientSecret(clientSecret)
                            .username("someone")
                            .password("someword")
                            .build();

但得到以下错误：

servlet [dispatcherServlet] 的 Servlet.service() 在路径为 [] 的上下文中抛出异常 [Handler dispatch failed; 嵌套异常是 java.lang.NoClassDefFoundError: org/jboss/resteasy/client/jaxrs/ResteasyClientBuilder] 的根本原因

请尝试将这些依赖项添加到您的项目 pom.xml 中。依赖项的版本可能是 3.6.0.Final 或 3.5.0.Final（我不确定您的 keycloak-admin-client 依赖项版本。但是，我使用了 keycloak-admin-client 3.0.0.Final 和 3.5.0.Final resteasy-client。它运行成功。）&nbsp; &nbsp; <dependency>&nbsp; &nbsp; &nbsp; &nbsp; <groupId>org.jboss.resteasy</groupId>&nbsp; &nbsp; &nbsp; &nbsp; <artifactId>resteasy-client</artifactId>&nbsp; &nbsp; </dependency>&nbsp; &nbsp; <dependency>&nbsp; &nbsp; &nbsp; &nbsp; <groupId>org.jboss.resteasy</groupId>&nbsp; &nbsp; &nbsp; &nbsp; <artifactId>resteasy-jackson2-provider</artifactId>&nbsp; &nbsp; </dependency>&nbsp; &nbsp; <dependency>&nbsp; &nbsp; &nbsp; &nbsp; <groupId>org.jboss.resteasy</groupId>&nbsp; &nbsp; &nbsp; &nbsp; <artifactId>resteasy-multipart-provider</artifactId>&nbsp; &nbsp; </dependency>
