//optimisticLock 这属性只有hibernate有，fetch也是，怎么能同时使用啊？？

@javax.persistence.Entity
@org.hibernate.annotations.Entity(optimisticLock = OptimisticLockType.VERSION) 
@javax.persistence.Table(name = "TB_CUSTOMER", schema = "PBUSER")
@org.hibernate.annotations.Table(appliesTo = "cc", fetch = FetchMode.SELECT)
public class Customer {
    private int id;

    @GeneratedValue
    @Id
    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

}
