假设我有两个简单的表要在我的Spring Boot
应用程序中实现。
这是ER图:
这是我的PasswordReset课:
@Data
@Entity
public class PasswordReset {
@Id @GeneratedValue Long passwordResetID;
String eMail;
String token;
String createdAt;
PasswordReset()
{
}
public PasswordReset(String eMail,String token,String createdAt)
{
this.eMail=eMail;
this.token=token;
this.createdAt=createdAt;
}
}
这是我的User课(部分):
@Data
@Entity
public class User {
@Id @GeneratedValue Long UserID;
String eMail;
String createdAt;
String updatedAt;
User()
{
}
public User(String eMail,String createdAt,String updatedAt)
{
this.eMail=eMail;
this.createdAt=createdAt;
this.updatedAt=updatedAt;
}
}
现在我的问题是如何在我的Spring Boot项目中创建外键,如我的 ER 图?
这是我的pom.xml:
