Spring learning-Hibernate Integration

Spring learning-Hibernate Integration
What is Spring integrated with Hibernate? 1 ). IOC containers are available to manage SessionFactory2 of Hibernate ). you need to configure the data source to the IOC container so that Hibernate uses the Spring declarative transaction Hibernate configuration file (less than a part of the Hibernate configuration), so you do not need to configure the data source here. associated. hbm. when configuring the SessionFactory instance in the IOC container, xml only needs to configure the dialect and Table Generation Policy. hibernate master Configuration

<Session-factory> <property name = "hibernate. dialect "> org. hibernate. dialect. mySQL5InnoDBDialect </property> <property name = "hibernate. show_ SQL "> true </property> <property name =" hibernate. format_ SQL "> true </property> <property name =" hibernate. hbm2ddl. auto "> update </property> <! -- Configure the attributes related to the hibernate second-level cache. --> </session-factory> Spring IOC container configuration
