Java @瞬态在JPA中工作不正常

我在使用JPA和

@Transient

注释时遇到问题。我正在使用SpringBoot和MySQL数据库。我不知道如何消除这个映射错误。尽管有

@Transient

注释，JPA似乎正在尝试为

多部分文件创建数据库条目。我也尝试过向getter和setter添加
@Transient
注释，但错误是相同的。请帮帮我

我得到的错误是：

不是从
导入org.springframework.data.annotation.Transient
我注意到在你的模型课上有两个错误。
1.导入Import javax.persistence.Transient；
2.从setter方法中删除瞬态anotation

@Transient
public String getPassword() {
    return password;
}

public void setPassword(String password) {
    this.password = password;
}

尝试使用byte[]作为userImage属性使用正确的
@Transient
注释，即来自
javax.persistence的注释，而不是spring数据注释。
@Transient
public String getPassword() {
    return password;
}

public void setPassword(String password) {
    this.password = password;
}
