型号类别

@Entity 
public class User {

    @Id 
    @Column
    private int id;
    private String firstName;
    private String lastName;

    //Setter and Getter

解决方法:

我们也面临同样的问题.我们已经在id列的xml和@GeneratedValue中创建了.解决方法是删除@GeneratedValue批注并手动输入id的值,默认情况下,jpa也需要很长时间,因此请提供长值,例如1l.

要进行自动生成,请遵循另一条规则.

与JPA相关的自动生成ID的问题已通过以下方式解决：

修改Person.java模型类,使其对Id属性具有以下注释：

@Id
@TableGenerator(name="TABLE_GEN",table="T_GENERATOR",pkColumnName="GEN_KEY",pkColumnValue="TEST",valueColumnName="GEN_VALUE",initialValue=1,allocationSize=1)
@GeneratedValue(strategy=GenerationType.TABLE, generator="TABLE_GEN")
public Long Id;

这将在mysql模式中创建一个名为T_GNERATOR的表,该表将跟踪休眠状态下Id和JPA的下一个值,而Hibernate知道如何检索该值.假定Id的初始值为1,并且从注释的属性中可以明显看出,它在每次新插入时都增加1.
