JPA實體mappagin不同的值

我有一個表中的列：它具有以下值狀態：P，A，E，C ....JPA實體mappagin不同的值

，因爲我展示一個JSP頁面上此值會我喜歡這個值映射到：P->處理，A - > .... E-> errror，C->完成

，所以我此做了類用於映射值：

import java.util.HashMap; 

public class FactoryStatusValue { 

private static final HashMap<String, String> statusValues; 

static{ 
    statusValues = new HashMap<String, String>(){{ 
     put("C","Completed"); 
     put("E","Errore"); 
     put("T","Terminato"); 
     put("P","Processing"); 
     put("N","Da processare"); 
     put("A","Attivà manuale"); 
    }}; 
} 

public static String getValue(String key){ 
    return statusValues.get(key); 
} 
}

，並在我這樣做的實體中：

/** 
    * The persistent class for the SETT_TB_BATCHREQUEST database table. 
    * 
    */ 
@Entity 
@Table(name="SETT_TB_BATCHREQUEST")

    }

但該表總是顯示： E，P，A，C ...... 爲什麼？

爲completenss這是jsp頁面

你能證明你的jsp？ – sanbhat

是的，我編輯的問題 –

我想我沒有理解問題，哪個表仍然顯示E，A，P ...？ jsp表或OR數據庫表？ – sanbhat

我經常觀察到，Hibernate不調用您的實體getter在訪問值特定場。

例如，如果status是一個字段，並且有人試圖呼叫getStatus()，hibernate不會調用您的實體的getStatus()方法。

因此，這將是更好的聲明transient場（不映射成一列）稱爲longStatus（說）你的實體類和有這方面的getter像下面。

private transient longStatus; 

public String getLongStatus() { 
    return FactoryStatusValue.getValue(this.status); 
}

您可能需要修改你的JSP訪問的entity.longStatus代替entity.status.

好的，讓我試試非常感謝你 –

你是一個天才男人！請你能解釋一下爲什麼需要Transient關鍵字？ –

'transient'關鍵字使得hibernate在映射時忽略該字段。如果一個字段被聲明爲'transient'，那麼hibernate不會嘗試將它映射到表中的任何一列，實體指向。由於longStatus只是您的實體類中的一次性非持久性字段，因此使其「暫時」變得有意義 – sanbhat
