Spring通过setter方式注入失败的经历

实现的功能:
一个Person类,Student和Teacher是两个实现类,在老师类里面注入学类
代码如下

package com.test.one.charpterday1;
public interface Person {
public void Say();
}
package com.test.one.charpterday1;

public class Student implements Person {
	@Override
	public void Say() {
		// TODO Auto-generated method stub
		System.out.println("祝老师端午节安康");
	}

}
package com.test.one.charpterday1;

public class Teacher implements Person {
	private Student student;
	public void setStudent(Student student) {
		this.student=student;
	}
	@Override
	public void Say() {
		// TODO Auto-generated method stub
		this.student.Say();
		System.out.println("I am a goog teacher!!!");
	}

}
package com.test.one.charpterdaytest;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.test.one.charpterday1.Person;
import com.test.one.charpterday1.Student;
public class DayTest01 {

	public static void main(String[] args) {
//		// TODO Auto-generated method stub
ApplicationContext applicationContext=new ClassPathXmlApplicationContext("applicationcontext.xml");
Person teacher=(Person)applicationContext.getBean("teacher");
teacher.Say();
	}

}

正确的因为注入的Student实例要在Teacher的bean里面—如下所示–
