如何使用java keycloak admin库在keycloak中处理多个操作之间的事务

import org.keycloak.admin.client.Keycloak;
import org.keycloak.admin.client.KeycloakBuilder;
import org.keycloak.admin.client.resource.RealmResource;

public class KeycloakTransactionExample {
    public static void main(String[] args) {
        // 创建Keycloak Admin客户端
        Keycloak keycloak = KeycloakBuilder.builder()
                .serverUrl("http://localhost:8080/auth")
                .realm("realm-name")
                .username("admin")
                .password("admin-password")
                .clientId("admin-cli")
                .build();

        // 开启事务
        RealmResource realmResource = keycloak.realm("realm-name");
        realmResource.startTransaction();

        try {
            // 执行操作
            // 创建用户
            realmResource.users().create(createUserRepresentation("user1"));
            // 更新用户
            realmResource.users().get("user1").update(updateUserRepresentation("user1"));
            // 删除用户
            realmResource.users().get("user1").remove();
            
            // 提交事务
            realmResource.commitTransaction();
        } catch (Exception e) {
            // 处理异常，例如回滚事务
            realmResource.rollbackTransaction();
            e.printStackTrace();
        }
    }

    // 创建用户的示例方法
    private static UserRepresentation createUserRepresentation(String username) {
        UserRepresentation user = new UserRepresentation();
        user.setUsername(username);
        // 设置其他用户属性
        return user;
    }

    // 更新用户的示例方法
    private static UserRepresentation updateUserRepresentation(String username) {
        UserRepresentation user = new UserRepresentation();
        user.setUsername(username);
        // 设置其他需要更新的用户属性
        return user;
    }
}
