未知序号值[46]对于枚举类错误与休眠

我正在开发一个Java Web应用程序使用Hibernate和Spring。我定义Enum如下：未知序号值[46]对于枚举类错误与休眠

public enum FeatureType implements ParentEnumInterface{ 

    VAL0(0, "VAL0"), VAL1(1, "VAL1"), VAL2(2, "VAL2"), VAL3(3, "VAL3"), VAL4(4, "VAL4"), VAL5(5, "VAL5"), 
    ... 
    VAL43(43, "VAL43"), VAL44(44, "VAL44"), VAL45(45, "VAL45"), VAL46(46, "VAL46"); 

    private String translate; 
    private FeatureType(int ordinal, String translate) 
    { 
     this.translate = translate; 
     setEnumOrdinal(this, ordinal); 
    } 

    public String getName() 
    { 
     return name(); 
    } 

    private static void setEnumOrdinal(Enum object, int ordinal){ 
     Field field; 
     try{ 
      field = object.getClass().getSuperclass().getDeclaredField("ordinal"); 
      field.setAccessible(true); 
      field.set(object, ordinal); 

     }catch(Exception ex){ 
      throw new RuntimeException("cannot update enum ordinal", ex); 
     } 
    } 
    public String getTranslate() 
    { 
     return translate; 
    } 


}

因为我有非常featureType并有可能我删除其中的一些在开发的时候，我定义ordinal所有featureType。

我用FeatureType枚举在我的实体如下：

public class MetaData implements Serializable{ 
    @Id 
    @GeneratedValue 
    private Long Id; 

    private FeatureType featureType; 

    // Getters And Setters 
}

我的应用程序完美的作品，只要FeatureType成员都小于46。然而，当我添加了47件，如下发生错误：

HTTP Status 500 - Request processing failed; nested exception is java.lang.IllegalArgumentException: Unknown ordinal value [46] for enum class [ir.javan.calk.enums.FeatureType]

这只是一个客串，也许是modifiing序不是一个好主意。 – Ralph

我按照[这里]使用这种方式（http://stackoverflow.com/questions/19449334） –

首先让我说点什么：我相信它是的（让我表达它友好）一个不太好的主意来操纵枚举序列！

我想这个问题是，你必须在枚举序差距。你用这个ordnials来映射他们的休眠状态。所以Hibernate使用OrdinalEnumValueMapper。通过此映射器所使用的代码是：

private Enum fromOrdinal(int ordinal) { 
    final Enum[] enumsByOrdinal = enumsByOrdinal(); 
    if (ordinal < 0 || ordinal >= enumsByOrdinal.length) { 
     throw new IllegalArgumentException(
       String.format("Unknown ordinal value [%s] for enum class [%s]", ordinal,enumClass.getName())); 
    } 
    return enumsByOrdinal[ordinal]; 
} 

private Enum[] enumsByOrdinal() { 
     if (enumsByOrdinal == null) { 
      enumsByOrdinal = enumClass.getEnumConstants(); 
      ... 
     } 
     return enumsByOrdinal; 
}

你注意到，此代码由T[] getEnumConstants()（的Class的方法）获得的枚举值的列表中的阵列，然后在序的位置访问该阵列。但是你改变了原来的东西，所以它会访问王的价值。 - 如果你幸运的话，它会尝试访问一个不在数组中的索引，并且发生异常，它有一个糟糕的一天，它会发现在该索引处有一个值，但它可能是错误的（因为的差距）。

解决方法：取出序maniulation和使用@Enumarated(value=EnumType.STRING)代替
