Spring 自学系列之IOC-5【简单属性的注入】

spring 支持简单属性的注入，格式为 <property name=… value=….>
例子如下所示：<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<bean name="userDAO" class="com.bjsxt.dao.impl.UserDAOImpl">
<property name="daoId" value="8"></property>
<property name="daoStatus" value="good"></property>
</bean>

<bean id="userService" class="com.bjsxt.service.UserService">
<!--
<property name="userDAO">
<ref bean="userDAO"/>
</property>
-->
<constructor-arg>
<ref bean="userDAO"/>
</constructor-arg>
</bean>

</beans>
