Log JPA schema creation with Hibernate

#javaee wednesday, april 15, 2015

The JPA provider can create the database schema from the Entity beans. This behaviour is configured in the persistence.xml file. You can display the SQL scripts which were used to generate the database schema with Hibernate.

Therefore you configure the hibernate.show_sql property to true and the property to create in your persistence.xml file:

    <property name="hibernate.show_sql" value="true" />
    <property name="" value="create" />

Also set the log level for the org.hibernate.tool.hbm2ddl logger to DEBUG.

The create SQL statements will appear in the log:

org.hibernate.tool.hbm2ddl.SchemaExport execute
Hibernate: create table customers (id bigint not null, ...
org.hibernate.tool.hbm2ddl.SchemaExport execute
