4.自动装配:

Person类

public class Person {


	private String name;
	
	private Address address;
	
	private Car car;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public Address getAddress() {
		return address;
	}

	public void setAddress(Address address) {
		this.address = address;
	}

	public Car getCar() {
		return car;
	}

	public void setCar(Car car) {
		this.car = car;
	}

	@Override
	public String toString() {
		return "Person [name=" + name + ", address=" + address + ", car=" + car + "]";
	}
	
	
	
}

<!-- 自动装配
	byName:根据bean的名字和当前bean的setter风格的属性名进行自动装备，若有匹配的，则装配，
			若没有则不装配
	byType:根据bean的类型和当前bean的属性的类型，IOC容器中，该类型bean只能有唯一！！
			如上有两个Address的bean时，就不能使用byType
 -->
<bean id="person" class="com.hcx.spring.beans.cautowire.Person"
	p:name="Tom"
	autowire="byName"
></bean>
	
</beans>

注意：在使用byName自动装配时，如上例出现address和address2两个bean，实际上spring会根据Person的address属性对应address的bean；如果属性名是address2，那么             就会对应address2的bean。
