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(); } }
