Hibernate: Add a property in my class that is not mapped to a db-table
提问by Adnan
I have a table tbl_skythat has 2 properties nameand modeland I would use Hibernate annotation like;
我有一个表tbl_sky有2个属性name和model我会使用Hibernate注释等;
@Entity
@Table(name="tbl_sky")
public class Sky implements Serializable {
private String name;
private String model;
private String status;
@Id
public String getName() {
return name;
}
.
.
.
But I need to add one more property statusthat does not exist in the table but is needed in the class. How could I declare that property so that I have it in my class but not in my db-table?
但是我需要再添加一个status在表中不存在但在类中需要的属性。我如何声明该属性，以便我在班级中拥有它，但在我的数据库表中却没有？
All help is appreciated.

Use @Transientannotation for field you are not going to store in DB:
@Transient对不打算存储在数据库中的字段使用注释：
@Transient
public String getStatus() {
return status;
}
or:
或者：
@Transient
private String status;

If you annotate a field with @Transientit will not be persisted.
如果你用@Transient它注释一个字段，它不会被持久化。
回答by Sean Patrick Floyd
Mark it as @Transient, and it won't be part of the DB schema.
将其标记为@Transient，它不会成为数据库架构的一部分。
