大家有没遇到这样的问题啊，我用uuid的主键生成策略，修改数据的时候变成了新增，不知道怎么解决，哪位大神帮解决下。代码如下：
//JPA 基类的标识
@MappedSuperclass
public abstract class PkidEntity {
@Id
@GenericGenerator(name="hibernate-uuid",strategy="uuid")
@GeneratedValue(generator="hibernate-uuid")
@Column(name="pkid", nullable=false)
protected String pkid;
public String getPkid() {
return pkid;
}
public void setPkid(String pkid) {
this.pkid = pkid;
}
}
但是我用序列的生成方式则没有这样的问题
@MappedSuperclass
public abstract class IdEntity {
protected Long id;
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "PKGen")
@SequenceGenerator(name = "PKGen", sequenceName = "HIBERNATE_SEQUENCE", allocationSize = 1)
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
}
