I try to index pdf file throught Hibernate Search @TikaBridge. According to the documentation the annotated field with TikaBridge should be any the following types:
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
I have a PDF entity which has a content field of byte array type as:
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;
/**

@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 + '}';
}
}
This entity is associated with Book Entity as follows:
@IndexedEmbedded
@OneToOne(cascade = CascadeType.ALL, fetch=FetchType.EAGER, targetEntity = PdfFile.class)
@JoinColumn(name="excerpt_id")
private PdfFile excerpt;
When deploy EAR on wildfly 10 I get the following error:

I am using Hibernate Search ORM 5.5.5.Final
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-search-orm</artifactId>
<version>${hibernate.search.version}</version>
<exclusions>
<exclusion> <!-- declare the exclusion here -->
<groupId>org.apache.lucene</groupId>

And Hibernate Entity Manager 5.0.11.Final
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>${hibernate.entity.manager}</version>
</dependency>
Can somebody help me?
I solved this using a java.sql.Blob type as:
@Lob
@Column(name = "content")
@Field
@TikaBridge
private Blob content;
For convert byte array to Blob I used a SerialBlob class:
byte[] content = IOUtils.toByteArray(file.toURI());
pdf = new PdfFile(fileName, new SerialBlob(content));
To search this field .ignoreFieldBridge() it has to be used
org.apache.lucene.search.Query luceneQuery = qb.keyword()
.onFields("title", "description", "authors.name", "excerpt.content")
.ignoreFieldBridge()
.matching(keyword)
.createQuery();
