我正在用jpa（springdatajpaversion2.3.0/hibernate5.1.0）运行一个spring启动项目，我如何强制使用@createdby注解@entity的字段的值？
实体：

import lombok.Getter;
import lombok.Setter;
import org.springframework.data.annotation.CreatedBy;
import org.springframework.data.annotation.CreatedDate;
import org.springframework.data.annotation.LastModifiedBy;
import org.springframework.data.annotation.LastModifiedDate;
import org.springframework.data.jpa.domain.support.AuditingEntityListener;

import javax.persistence.*;
import java.util.Date;

@Entity(...)
@Getter
@Setter
@EntityListeners(AuditingEntityListener.class)
public class SomeEntity{

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "create_timestamp", nullable = false, updatable = false)
    @CreatedDate
    private Date createTimestamp;

    @Column(name = "create_user")
    @CreatedBy
    private String createUser;

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "update_timestamp")
    @LastModifiedDate
    private Date updateTimestamp;

    @Column(name = "update_user")
    @LastModifiedBy
    private String updateUser;
}

配置：

@EnableJpaAuditing(auditorAwareRef = "auditorProvider")
@Component
public class AuditConfig implements AuditorAware<String> {

    /**
     * The Constant SYSTEM_ACCOUNT.
     */
    public static final String SYSTEM_ACCOUNT = "system";

    /**
     * Gets the current auditor.
     *
     * @return the current auditor
     */
    @Override
    public Optional<String> getCurrentAuditor() {
        String currentUser = getUserFromSecurityContext();
        return Optional.ofNullable(currentUser);
    }
}

问题是，即使我使用以下代码强制值：

someEntity.setCreateUser("some other user");

该值被jpa自动覆盖。除了在表/实体中创建另一个字段之外，还有其他解决方案吗？
