HSEARCH000151：バイト型のオブジェクトから入力ストリームを取得できません

Question

Hibernate Search @TikaBridgeを使用してpdfファイルを索引付けしようとしています。文書によるとTikaBridgeとの注釈付きフィールドは任意のfolowingタイプでなければなりません：

String - where the string value is interpreted as a file path 
URI - where the URI is interpreted as a resource URI 
byte[] 
java.sql.Blob 

私はPDFエンティティウィッヒを持っているように、バイト配列型のコンテンツ分野を持っている：このエンティティが関連付けられて

を使用しています誰かが私を助けることができますか？

Answer 1

私はとのjava.sql.Blobタイプを使用して、これを解決：私はSerialBlobクラス使用BLOBに変換バイト配列について

@Lob 
@Column(name = "content") 
@Field 
@TikaBridge 
private Blob content; 

：このフィールドを検索するには

byte[] content = IOUtils.toByteArray(file.toURI()); 
pdf = new PdfFile(fileName, new SerialBlob(content)); 

を.ignoreFieldBridge()それは使用する必要があります

org.apache.lucene.search.Query luceneQuery = qb.keyword() 
       .onFields("title", "description", "authors.name", "excerpt.content") 
       .ignoreFieldBridge() 
       .matching(keyword) 
       .createQuery();
