Usage

From source file:org.ngrinder.infra.config.DatabaseConfig.java

/**
 * Create {@link LocalContainerEntityManagerFactoryBean} bean for Hibernate. Hibernate doesn't
 * support the search for the {@link Entity} classes in the other Jar files. This method
 * directly searches the {@link Entity} classes with {@link Reflections} not using Hibernate
 * entity class search feature to overcome the limitation
 * <p/>/*from w ww.ja v  a 2  s. c  o m*/
 * use annotation DependsOn to insure after databaseUpdater is
 *
 * @return {@link LocalContainerEntityManagerFactoryBean}
