Spring学习01——HelloSpring

 

这是一个spring入门demo:

package com.su.test;

public class HelloWorld {

    public void say(){
        System.out.println("Spring4!");
    }
}
package com.su.service;

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

import com.su.test.HelloWorld;

public class Test {
    public static void main(String[] args) {
  //通过xml配置文件来获取对象,而非使用new ApplicationContext ac
=new ClassPathXmlApplicationContext("beans.xml"); HelloWorld helloWorld=(HelloWorld)ac.getBean("helloWorld"); helloWorld.say(); } }
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="helloWorld" class="com.su.test.HelloWorld"></bean>
  
</beans>
