SpringMVC --hello world

直接上代碼：
1.寫一個輸出hello world 的類

package cn.itcat.spring.sh.ioc.creatobject;public class HelloWorld {    public void sayHello() {                System.out.println("hello xiajun");         }}

2.把類放入Spring容器

<?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-2.5.xsd">     <bean id="helloWorld" class="cn.itcat.spring.sh.ioc.creatobject.HelloWorld"></bean></beans>

3.測試

package cn.itcast.spring.sh.test;import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import cn.itcat.spring.sh.ioc.creatobject.HelloWorld;public class CreatObjectTest {    @Test    public void testCreatObjest(){        /**         * 1.啟動spring容器         * 2.從spring容器中把對象去出來         * 3.對象調用方法         */        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");        HelloWorld helloworld = (HelloWorld)context.getBean("helloWorld");        helloworld.sayHello();    }}
