1.applicationContext.xml

    <bean id="andy" class="com.imooc.spring.ioc.entity.Child">
      <constructor-arg name="name" value="安迪"/>
        <constructor-arg name="apple" ref="sourApple"/>
    </bean>

 public Child(String name, Apple apple)
    {
        System.out.println("构造方法参数apple：" + apple);
        this.name = name;
        this.apple = apple;
    }
