Spring依赖注入

一、Set注入

<bean id="userDao" class="com.finnlee.daoImpl.UserDaoImpl" scope="prototype" ></bean>
//name="userDao"是属性  ref="userDao" 是引用上面bean对象
<bean id="userService" class="com.itheima.service.impl.UserServiceImpl">
<property name="userDao" ref="userDao"/>  //Set注入

<constructor-arg name="userDao" ref="userDao"></constructor-arg>  //构造方法注入

</bean>



xmlns:p="http://www.springframework.org/schema/p"

<bean id="userService" class="com.itheima.service.impl.UserServiceImpl" p:userDao-ref="userDao"/>
