Hibernate, force table name in low box

Question

I am using Hibernate 5.2.1.Final as an implementation to handle Mysql database. The problem is that the tables are being generated with the first letter in high box, would like to force to be all in low box via persistence file. Currently my file is this:

<persistence-unit name="testeUP" transaction-type="RESOURCE_LOCAL">
    <properties>
        <property name="javax.persistence.jdbc.url" value="jdbc:mysql://192.168.56.100:3306/locadora"/>
        <property name="javax.persistence.jdbc.user" value="root"/>
        <property name="javax.persistence.jdbc.password" value="1QAZxsw2"/>
        <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>

        <property name="hibernate.hbm2ddl.auto" value="update"/>
        <property name="hibernate.show_sql" value="true"/>
        <property name="hibernate.format_sql" value="true"/>
        <property name="hibernate.diaLect" value="org.hibernate.diaLect.MySQLDiaLect"/>
    </properties>
</persistence-unit>

Is it possible to force this behavior? If so, how?

Answer 1

In your entities, use the annotation @Table. Here’s an example:

@Entity
@Table(name = "tabela_caixa_baixa")
public class MinhaTabela implements Serializable {
    // ...
}

When the annotation @Table is absent, it is understood that the table name will be the default (default). The default is to leave the persistence Provider (in his case, Hibernate) give the name he thinks best.

Since what you want is a different behavior from the default (don’t let Hibernate give the name the way he wants), then you specify the desired behavior by using the annotation.
