Simple Hibernate XML Configuration

David Winterfeldt

2008


A simple example using Hibernate with an XML configuration to find, save, and update a record.

1. Spring Configuration

The jdbc:embedded-database element is used to initialize the test HSQLDB database and the LocalSessionFactoryBean is using to configure Hibernate. The mappingLocations property is used to set a list of Hibernate XML mapping files. The Person DAO is configured using Hibernate's session factory.
