I’m mapping a field @lob to save image to a table, but jpa creates the table, but does not create the column. I created the column manually in MYSQL, but then the bytes do not persist either.
My Entity:
@Entity
@Table(name = "TB_IMAGEM")
public class Imagem {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Lob
@Column(name = "IMAGE_CONTENT")
private byte[] imagemByte;//não cria somente essa coluna, se crio manualmente, não persiste e nem Lê essa coluna
//getters e setters
}
My persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
<persistence-unit name="primary">

<properties>

<property name="hibernate.show_sql" value="true" />
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
</properties>
</persistence-unit>
In the console it creates the table, but not the blob column.

Which version of Hibernate are you using? And Mysql? If you’re using Maven, edit your question and ask your own
pom.xml, please.– Felipe Marinho
I am using MYSQL 5.5, Hibernate 4.1.1. Thank you.
– Samuel Oliveira Chaves
Maybe there is a problem with your dependencies. You have declared the following dependency
hibernate-jpa-2.1-api, but JPA 2.1 is only supported by Hibernate as of version 4.3.– Felipe Marinho
I will use the version of the newest Hibernate and tell you.
– Samuel Oliveira Chaves
I upgraded the dependency to jboss-javaee-7.0-with-Hibernate and it upgraded the whole Hibernate dependency to 4.3, but it still didn’t work.
– Samuel Oliveira Chaves
Do you have any idea what’s going on?
