具有JPA +循环引用的继承的抽象类

Question

I have an abstract class AbstractEntity that contains two fields:

• lastEditTime (LocalDateTime)
• lastEditUser (UserEntity)

Below is the code:

@MappedSuperclass
public abstract class AbstractEntity {

    protected LocalDateTime lastEditTime;

    protected UserEntity lastEditUser;

    protected AbstractEntity () { }

    protected AbstractEntity (UserEntity creatorUser) {
        lastEditTime = LocalDateTime.now();
        lastEditUser = creatorUser;
    }

    public LocalDateTime getLastEditTime() {
        return lastEditTime;
    }

    public void setLastEditTime(LocalDateTime lastEditTime) {
        this.lastEditTime = lastEditTime;
    }

    public UserEntity getLastEditUser() {
        return lastEditUser;
    }

    public void setLastEditUser(UserEntity lastEditUser) {
        this.lastEditUser = lastEditUser;
    }
}

Then I have the UserEntity class that has many different fields:

@Entity
@Table(name = "Users")
public class UserEntity extends AbstractEntity {

    @Id
    private String name;

    private String password;

    ...

}

Eclipse shows the following error message:

In implied association override "lastEditUser", join column "lastEditUser_name" cannot be resolved on table "users"

What does it mean? How can I resolve it?

thanks!

Answer 1

I disconnected eclipse Datasource. Then I clean the project (the error messages were gone), then I deleted the tables in the database, and finally I run a test case to recreate the tables.

The new table has the two inherited columns.
