我在 PostgreSQL 中使用表继承,表业务扩展用户。
@Entity
@Table(schema = "service", name = "users")
public class Users {
@Id
private String id;
@Column(name = "nickname")
private String name;
private String password;
public Users() {
}
public Users(String id, String password, String name) {
this.id = id;
this.password = password;
this.name = name;
}
// getters and setters
}
表业务具有用户没有的列short_name 。当我使用这个时:
@Entity
@Table(schema = "service", name = "business")
public class Business extends Users {
@Column(name = "short_name")
private String shortName;
}
IntelliJ IDEA 告诉我没有列short_name并且只接受users表值。如何正确解决这个问题?它不会起作用,还是只是IDEA的问题?
