spring数据cassandra无法转换enum

Question

我试图让spring数据将我的枚举类型转换为cassandra中的int字段，但我得到了以下异常：

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   

这是我正在使用的一段代码：

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

Answer 1

由于spring-data cassandra不支持它，因此可以在getters/ssetters中实现此逻辑。

@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();
    }
