How to scan packages for Hibernate entities instead of using hbm.xml?

Question

I currently scan packages for DAOs and services using Spring 3.1 & Hibernate 4 via <context:component-scan> Is there a way to do the same for classes marked @Entity instead of using the configLocation property and a hbm.xml file?

<hibernate-configuration>     <session-factory>         <mapping class="com.example.model.User" />             <!-- etc. -->     </session-factory> </hibernate-configuration> 

Answer 1

<bean id="sessionFactory"   class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"   p:dataSource-ref="dataSource"   p:configLocation="WEB-INF/classes/hibernate.cfg.xml"   p:packagesToScan="com.example.model" /> 

Will scan everything in model package. I use my cfg.xml to contains settings like show_sql, and hb2ddl.auto.

You can do some like this in application context.xml file to scan all annotation classes -

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">     <property name="dataSource" ref="dataSource" />     <property name="lobHandler" ref="lobHandler"/> <property name="packagesToScan">     <list>         <value>com.idc.scd.domain</value>         <value>com.idc.scd.domain.dropdown</value>         <value>com.idc.scd.domain.external</value>         <value>com.idc.scd.domain.pk</value>     </list> </property>     <property name="hibernateProperties">       <props>             <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>             <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>         <prop key="hibernate.format_sql">${hibernate.format_sql}</prop>         <prop key="hibernate.use_sql_comments">${hibernate.use_sql_comments}</prop>         <prop key="hbm2ddl.auto">validate</prop>         <prop key="hibernate.cache.use_query_cache">true</prop>         <prop key="hibernate.connection.release_mode">after_statement</prop>         <prop key="hibernate.cache.provider_class">net.sf.ehcache.hibernate.EhCacheProvider</prop>         <prop key="hibernate.cache.use_second_level_cache">${hibernate.cache.use_second_level_cache}</prop>         <prop key="hibernate.cache.use_structured_entries">${hibernate.cache.use_structured_entries}</prop>         <prop key="hibernate.jdbc.fetch_size">${hibernate.jdbc.fetch_size}</prop>         </props>     </property> </bean>
