GeneratedValue

```
@Target(value={METHOD,FIELD})
 @Retention(value=RUNTIME)
public @interface GeneratedValue
```
Provides for the specification of generation strategies for the values of primary keys.
The GeneratedValue annotation may be applied to a primary key property or field of an entity or mapped superclass in conjunction with the Id annotation. The use of the GeneratedValue annotation is only required to be supported for simple primary keys. Use of the GeneratedValue annotation is not supported for derived primary keys.
```
     Example 1:

     @Id
     @GeneratedValue(strategy=SEQUENCE, generator="CUST_SEQ")
     @Column(name="CUST_ID")
     public Long getId() { return id; }

     Example 2:

     @Id
     @GeneratedValue(strategy=TABLE, generator="CUST_GEN")
     @Column(name="CUST_ID")
     Long id;
 
```
