映射例外与CollectionOfElements

Question

我试图让这个映射工作休眠，但我得到这个奇怪的异常消息

Could not determine type for: foo.ProcessUser, at table: ProcessUser_onetimeCodes, for columns: [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; 
    } 
} 

任何人能发现什么是错在这里吗？ 我有hibernate.hbm2ddl.auto上create

Answer 1

我发现了错误。

您不能在其中一个类中的属性和另一个类中的getter上进行映射。他们应该匹配。

因此，我改变

@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; 
    } 
} 

到

@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; 
    } 
} 

和中提琴。 如果你问我，这很愚蠢。
