使用 CollectionOfElements 映射休眠中的异常

Question

我试图让这个映射工作，但我收到这个奇怪的异常消息

无法确定类型：foo.ProcessUser，表：ProcessUser_onetimeCodes，列：[org.hibernate.mapping.Column(processUser)]

@Entity
public class ProcessUser {

  @Setter
  private List<OnetimeCodes> onetimeCodes;

  @CollectionOfElements
public List<OnetimeCodes> getOnetimeCodes() {
    return onetimeCodes;
  }
}


@Embeddable
@Data
public class OnetimeCodes {

    @Parent
    private ProcessUser processUser;

    @Column(nullable=false)
    @NotEmpty
    private String password;


    public OnetimeCodes(ProcessUser processUser, String password) {
        this.processUser = processUser;
        this.password = password;
    }
}

有人能发现这里出了什么问题吗？ 我在 create 上有 hibernate.hbm2ddl.auto

Answer 1

我发现了错误。

您不能在一个类中的属性上进行映射，而在另一个类中的 getter 上进行映射。他们应该匹配。

所以我换成

@Embeddable
@Data
public class OnetimeCodes {

    @Parent
    private ProcessUser processUser;

    @Column(nullable=false)
    @NotEmpty
    private String password;


    public OnetimeCodes(ProcessUser processUser, String password) {
        this.processUser = processUser;
        this.password = password;
    }
}

了

@Embeddable
public class OnetimeCodes {

    private ProcessUser processUser;

    private String password;

    public OnetimeCodes(ProcessUser processUser, String password) {
        this.processUser = processUser;
        this.password = password;
    }

    @Parent
    public ProcessUser getProcessUser() {
        return processUser;
    }

    public void setProcessUser(ProcessUser processUser) {
        this.processUser = processUser;
    }

    @Column(nullable=false)
    @NotEmpty
    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

如果你问我的话，我非常愚蠢。
