SSH框架入门学习之二(spring)

Spring也是一个开源框架，我在学习Spring的时候，觉得最重要的几点是：IOC（控制反转）、AOP（面向切面）和容器概念。

具体的教程还请大家去看网上的视频，这里贴一个小Demo以供学习。（前提是大家把该导入的jar包都导入了）

1、Student类和Teacher类

public class Student {
	private String name;
	
	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
	
	public void sayHello() {
		System.out.println("Hi," + name);
	}
}

import java.util.List;


public class Teacher {
	private List stuList;
	private String name;
	
	public List getStuList() {
		return stuList;
	}
	public void setStuList(List stuList) {
		this.stuList = stuList;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	
	public void myStu() {
		System.out.println(name + " :");
		for(int i = 0; i < stuList.size(); i++)
			System.out.println(stuList.get(i).getName());
	}
}

2、配置文件：applicationContext.xml的配置

3、主类：main（直接运行即可）

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


public class main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
		
		Student stu = (Student) ac.getBean("student_1");
		stu.sayHello();
		
		Teacher tec = (Teacher) ac.getBean("teacher");
		tec.myStu();
	}
}
