HSEARCH000151：無法從類型爲byte的對象獲取輸入流

Question

我嘗試通過Hibernate Search @TikaBridge索引pdf文件。根據文檔與TikaBridge註釋字段應該是任何如下因素類型：

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 

我有一個PDF實體至極具有字節數組類型的內容字段爲：

package models; 

import java.io.Serializable; 
import java.util.Objects; 
import javax.persistence.Column; 
import javax.persistence.Entity; 
import javax.persistence.Table; 
import javax.persistence.GeneratedValue; 
import javax.persistence.GenerationType; 
import javax.persistence.Id; 
import javax.persistence.Lob; 
import org.hibernate.search.annotations.Field; 

import org.hibernate.search.annotations.Indexed; 
import org.hibernate.search.annotations.TikaBridge; 

/** 
* 
* @author sergio 
*/ 
@Indexed 
@Entity 
@Table(name = "PDFS") 
public class PdfFile implements Serializable { 

    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    private Long id; 

    @Column(name = "file_name") 
    private String fileName; 

    @Lob 
    @Column(name = "content") 
    @Field 
    @TikaBridge 
    private byte[] content; 

    public PdfFile() { 
    } 

    public PdfFile(String fileName, byte[] content) { 
     this.fileName = fileName; 
     this.content = content; 
    } 

    public Long getId() { 
     return id; 
    } 

    public void setId(Long id) { 
     this.id = id; 
    } 

    public String getFileName() { 
     return fileName; 
    } 

    public void setFileName(String fileName) { 
     this.fileName = fileName; 
    } 

    public byte[] getContent() { 
     return content; 
    } 

    public void setContent(byte[] content) { 
     this.content = content; 
    } 

    @Override 
    public int hashCode() { 
     int hash = 3; 
     hash = 59 * hash + Objects.hashCode(this.id); 
     hash = 59 * hash + Objects.hashCode(this.fileName); 
     return hash; 
    } 

    @Override 
    public boolean equals(Object obj) { 
     if (this == obj) { 
      return true; 
     } 
     if (obj == null) { 
      return false; 
     } 
     if (getClass() != obj.getClass()) { 
      return false; 
     } 
     final PdfFile other = (PdfFile) obj; 
     if (!Objects.equals(this.fileName, other.fileName)) { 
      return false; 
     } 
     if (!Objects.equals(this.id, other.id)) { 
      return false; 
     } 
     return true; 
    } 

    @Override 
    public String toString() { 
     return "PdfFile{" + "id=" + id + ", fileName=" + fileName + '}'; 
    } 
} 

該實體相關聯的與圖書實體如下：

@IndexedEmbedded 
    @OneToOne(cascade = CascadeType.ALL, fetch=FetchType.EAGER, targetEntity = PdfFile.class) 
    @JoinColumn(name="excerpt_id") 
    private PdfFile excerpt; 

當wildfly 10我收到以下錯誤部署EAR：

我使用Hibernate Search的ORM 5.5.5.Final

<dependency> 
      <groupId>org.hibernate</groupId> 
      <artifactId>hibernate-search-orm</artifactId> 
      <version>${hibernate.search.version}</version>

        <artifactId>lucene-backward-codecs</artifactId> 
       </exclusion> 
      </exclusions> 
     </dependency> 

和Hibernate的實體管理器5.0.11.Final

<dependency> 
      <groupId>org.hibernate</groupId> 
      <artifactId>hibernate-entitymanager</artifactId> 
      <version>${hibernate.entity.manager}</version>

有人可以幫助我嗎？

我解決了這個使用的java.sql.Blob類型：

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

對於轉換字節數組BLOB我用的SerialBlob類：

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

要搜索該字段.ignoreFieldBridge()它必須被使用

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