我一整天都在用头撞这个，但好像没把它弄好。。。我相信你们中的一些人会看到这一点，马上知道答案。
在mysql数据库中，我有一个表 RFQ_HEADER 有主键的 rfq_no . 我还有一张table line_item 它的复合主键由 rfq_fk 以及 item_no 细节
rfqheader类

@Entity
@Table(name = "rfq_header")
public class RfqHeader implements Serializable  {
private static final long serialVersionUID = 1L;

@Id @Column(name = "rfq_no")                    private String rfqNo;
