public void setInjectionDAO(InjectionDAO injectionDAO) {
	this.injectionDAO = injectionDAO;
}

<bean id="injectionService" class="mao.mao.injection.InjectionServiceImpl"> <constructor-arg name="injectionDAO" ref="injectionDao"/> </bean>code

<bean id="injectionDao" class="mao.mao.injection.InjectionDAOImpl">
