彈簧數據卡桑德拉無法枚舉轉換

Question

我想有彈簧的數據我的枚舉類型轉換爲和INT場卡桑德拉，但我發現以下異常：

Unexpected runtime exception java.lang.IllegalArgumentException: 
Value 2 of type class com.twc.atg.td.dbo.client.ClassCode does not correspond to any CQL3 type 

這裏是這段代碼我使用：

@Enumerated(EnumType.ORDINAL) 
@Column("class_code") 
public ClassCode classCode; 

Answer 1

因爲它不是由彈簧數據卡桑德拉支持，可以實現在getter/setter方法這個邏輯。

@Table 
public class Writer { 
    ... 
    public enum WriterType { 
     POET, DETECTIVE, JOUNALIST 
    } 

    ... 
    @Column(value = "writer_type") 
    private Integer writerType; 

    ... 
    public WriterType getWriterType() { 
     return WriterType.values()[writerType]; 
    } 

    public void setWriterType(WriterType writerType) { 
     this.writerType = writerType.ordinal(); 
    }
