java-休眠搜索在索引中存储byte []

我的POJO中有以下配置：

@Field(index = Index.NO, store = Store.YES)
private byte[] file;

启动我的Apps容器时,出现以下异常：

如何在Hibernate Search(Lucene)索引中存储字节数组？

解决方法:

您将需要一个field bridge.

例如：

@Field(index = Index.NO, store = Store.YES)
@FieldBridge(impl = MyFieldBridge.class)
private byte[] file;


//The file bridge
public class MyFieldBridge implements StringBridge {

    @Override
    public String objectToString(final Object object) {

        byte[] file = (byte[]) object;

        return MagicFileUtil.getTextContent(file)
    }
}
