Ebeanがプリミティブでない@Transientメンバ変数を認識しないのはなぜですか？

Question

itemsをEbeanの永続性から除外したいと思います。ここで

は私のBeanです：

package entity; 

import java.util.Date; 

import javax.persistence.Entity; 
import javax.persistence.Id; 
import javax.persistence.Table; 
import javax.persistence.Transient; 

import com.avaje.ebean.validation.Length; 
import com.avaje.ebean.validation.NotNull; 

@Entity() 
@Table(name="profile") 
public class Profile { 

    private Item[] items; 

    @Transient 
    public Item[] getItems() { 
     return items; 
    } 

    public void setItems(Item[] items) { 
     this.items = items; 
    } 

    @Id 
    private int id; 

    @Length(max=50) 
    @NotNull 
    private String externalReference; 

    ... 

しかし、私は次のスタックトレースを取得する：それはあるように

誰かがどのように正しく@Transientとしてメンバ変数itemsを宣言することを教えてもらえます永続性から除外されていますか？この問題を解決するために

Answer 1

、あなたは以下に示すように、フィールドitems（ないgetItems()上）に@Transient注釈を適用する必要があります。

@Entity() 
@Table(name="profile") 
public class Profile { 

    @Id 
    private int id; 

    @Transient 
    private Item[] items; 

    public Item[] getItems() { 
    return items; 
    } 

    ... 
} 

PS：あなたが@Transientフィールドを持っている場合は、必ずことを確認getterメソッドまたはフィールドのいずれかにJPAアノテーションを一貫して配置し、両方の場所でJPAアノテーションを配布しないようにしています。現在のコードでは、他のJPA注釈（@Idなど）は@Transient以外のフィールドにマークされています。

しかし、私はJPA仕様やHibernateで何も見つけられませんでした。

Answer 2

これは4.0.1より前のバージョンのEBeanのバグです。

1. 変更リストにプロパティまたは配列ではなく、設定します。仕事は周りにあります。

2. 可能であればフィールドを「一時的」にもマークします。つまり、フィールドでJavaシリアル化を使用する必要がない場合です。

この関連bug reportで述べたように。
