Question

我的域名类：

'//:my_proto' does not have mandatory provider 'py'.

这是我的测试方法：

@Entity
@Table(name="ZZ_USER_INFO", schema="PDS_OWNER")
public class User implements Serializable{

    private static final long serialVersionUID = 1317056412866001134L;  
    public User(){

    }   
    @EmbeddedId
    private UserPk userPk;  

    @Column(name="AGE", nullable=false)
    private int userAge;

    public UserPk getUserPk() {
        return userPk;
    }

    public void setUserPk(UserPk userPk) {
        this.userPk = userPk;
    }

    public int getUserAge() {
        return userAge;
    }

    public void setUserAge(int userAge) {
        this.userAge = userAge;
    }

}

public class UserPk implements Serializable{

    private static final long serialVersionUID = 237150872186063319L;

        public UserPk(){

        }   

        @SequenceGenerator(name="ZZ_USER_INFO_SEQ", sequenceName="ZZ_USER_INFO_SEQ")
        @GeneratedValue(strategy = GenerationType.AUTO, generator="ZZ_USER_INFO_SEQ")
        @Column(name="USER_ID", nullable=false)
        private long userId;

        @Column(name="USER_NAME", nullable=false)
        private String userName;

        public long getUserId() {
            return userId;
        }

        public void setUserId(long userId) {
            this.userId = userId;
        }

        public String getUserName() {
            return userName;
        }

        public void setUserName(String userName) {
            this.userName = userName;
        }   

    }

当我在@EmbeddedId中使用@SequenceGenerator时，它在Oracle中不起作用。在表中，我看到USER_ID列中的默认值为零。

当我使用@Id时，相同的代码工作正常。

有人可以帮我解决如何在JPA @EmbeddedId（复合键）中使用Oracle sequecne生成器

感谢您的帮助。

Oracle表序列生成器不使用JPA Composite主键
