spring2.5基于注解和XML等配置应用

三种实例化Bean的方法1.使用类构造器<bean id="personService" class="cn.oseica.impl.PersonServiceBean"></bean>2．使用静态类工厂<bean id="personService2" class="cn.oseica.impl.PersonFactory" factory-method="createPerson"/>3．使用实例类工厂<bean id="personFactory" class="cn. oseica.impl.PersonFactory"/><bean id="personService3" factory-bean="personFactory" factory-method="createPerson"/>控制反转的实现-依赖注入xml注入注入其他bean外部bean<bean id="person"class="com.oseica.dao.PersonImpl"></bean><bean id="personService"class="com.oseica.service.PersonService"> <property name="person"ref="person"></property></bean>内部bean （最好不要被其他bean使用）<bean id="personService"class="com.oseica.service.PersonService"> <property name="person"><bean class="com.oseica.dao.PersonImpl"></bean></property></bean>注入属性<bean id="personService"class="com.oseica.service.PersonService"> <property name="id"value="23"></property></bean>构造器注入<bean id="person"class="com.oseica.dao.PersonImpl"></bean><bean id="personService"class="com.oseica.service.PersonService"> <constructor-arg index="0"type="com.oseica.dao.IPerson"ref="person"/>
