BUG：

Defines a single (usually named) bean. A bean definition may contain nested（巢狀）tags for  constructor arguments, property values, lookup methods, and replaced methods. Mixing  constructor injection and setter injection on the same bean is explicitly supported.

beans.xml：

	<bean id="person" class="com.spring.beans.autowire.Person">
		<property name="address" ref="address"></property>
		<property name="car" ref="car"></property>
		<property name="name" value="mmb"></property>
	</bean>
 

	public Person() {
		super();
