<?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.wishwzp.test.HelloWorld"></bean> </beans>
HelloWorld.java
package com.wishwzp.test; public class HelloWorld { public void say(){ System.out.println("Spring4你好!"); } }
Test.java
package com.wishwzp.service; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.wishwzp.test.HelloWorld; public class Test { public static void main(String[] args) { ApplicationContext ac=new ClassPathXmlApplicationContext("beans.xml"); HelloWorld helloWorld=(HelloWorld)ac.getBean("helloWorld"); helloWorld.say(); } }
运行结果显示:
