java巩固练习Spring 的bean注入方式有几种demo例子

package com.akun; import com.akun.pojo.Score; import com.akun.pojo.Student; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Demo { public static void main(String[] args) { ApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring.xml"); // 1 Score scoreBean1 = applicationContext.getBean("scoreBean1", Score.class); System.out.println(scoreBean1.toString()); // 2 Student StudentBean1 = applicationContext.getBean("StudentBean1", Student.class); System.out.println(StudentBean1.toString()); // 3 Student StudentBean2 = applicationContext.getBean("StudentBean2", Student.class); System.out.println(StudentBean2.toString()); // 4 Score scoreBean2 = applicationContext.getBean("scoreBean2", Score.class); System.out.println(scoreBean2.toString()); // 5 Score scoreBean3 = applicationContext.getBean("scoreBean3", Score.class); System.out.println(scoreBean3.toString()); // 6 Score scoreBean4 = applicationContext.getBean("scoreBean4", Score.class); System.out.println(scoreBean4.toString()); } }
