- a type variablePK

This class serves as the Base class for all other Managers - namely to hold common CRUD methods that they might all use. You should only need to extend this class when your require custom CRUD logic.
To register this class in your Spring context file, use the following XML.
<bean id="userManager" class="com.gisgraphy.service.impl.GenericManagerImpl"> <constructor-arg> <bean class="com.gisgraphy.dao.hibernate.GenericDaoHibernate"> <constructor-arg value="com.gisgraphy.model.User"/> <property name="sessionFactory" ref="sessionFactory"/> </bean> </constructor-arg> </bean>
If you're using iBATIS instead of Hibernate, use:
<bean id="userManager" class="com.gisgraphy.service.impl.GenericManagerImpl"> <constructor-arg> <bean class="com.gisgraphy.dao.ibatis.GenericDaoiBatis"> <constructor-arg value="com.gisgraphy.model.User"/> <property name="dataSource" ref="dataSource"/> <property name="sqlMapClient" ref="sqlMapClient"/> </bean> </constructor-arg> </bean>
