我试图让spring-data将我的枚举类型转换为cassandra中的int字段,但出现以下异常:

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


这是我正在使用的代码:

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

最佳答案

由于spring-data-cassandra不支持它,因此您可以在getter / setter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();
    }
