<id name="id" type="java.lang.Integer">

</generator>

@Id
@GeneratedValue(strategy=GenerationType.SEQUENCE,generator="sequence")
//seq_biz_claim_voucher_detail为oracle序列名称allocationSize设置自动增长数
@SequenceGenerator(name="sequence",sequenceName="seq_biz_claim_voucher_detail",allocationSize=1)
@Column(name="ID", unique=true, nullable=false, precision=6, scale=0)
public Integer getId() {
return this.id;
}
