Spring--(7)自動裝配

spring的自動裝配在工程中用得比較少，它沒有常規配置清晰明瞭。
//Address類

public class Address {
	private String city;
	private String street;
}

//Car類

public class Car {
	private String brand;
	private double price;
}

//Person類

public class Person {
	private String name;
	private Address address;
	private Car car;
}

配置文件

<bean id="address" class="com.test.autowired.Address" p:city="Beijing" p:street="Huilongguan">
	</bean>
	<bean id="car" class="com.test.autowired.Car">
		<property name="brand" value="Audi"></property>
		<property name="price">
			<value>300000</value>
		</property>
	</bean>
	
	<!-- 根據 名字 進行自動裝配 -->
	<!--bean id="address" 要與Person中的setAddress(Address address)參數一致-->
	<bean id="person" class="com.test.autowired.Person" p:name="zhangsan" autowire="byName"></bean>
