EclipseLink ValidationException - 非實體[class long]作爲關係屬性[field providerId]中的目標實體

Question

嘗試將應用程序部署到Glassfish時收到以下錯誤。顯然，我的關係有些不正確。嘗試部署時從GlassFish服務器

錯誤：

在我的「治療」類文件

 ValidationException Exception Description: [class edu...clinic.Treatment] 
uses a non-entity [class long] as target entity in the relationship attribute 
[field providerId] 

多到一的關係：在

@Entiity 
... 
@ManyToOne 
    @JoinColumn(name = "provider_fk", referencedColumnName = "npi") 
    private long providerId; 

一多關係我'提供商的檔案文件：

@Entity 
    ... 
@Id 
    @Column(name = "NPI") 
    private long npi; 
... 
    @OneToMany(mappedBy = "providerId", targetEntity=Treatment.class) 
     @OrderBy 
     private List<Treatment> treatments; 

我相信我的註釋是正確的，但有些不對。我很感激任何有關如何糾正這一問題的建議。

Answer 1

嘗試以下， 治療實體變化

private long providerId; 

到

private Provider provider; 

在提供實體變化

@OneToMany(mappedBy = "providerId", targetEntity=Treatment.class) 

到

@OneToMany(mappedBy = "provider", targetEntity=Treatment.class)
