ssm框架学习之spring入门（2）——spring的第一个测试项目

参考链接：https://blog.csdn.net/Evankaka/article/details/44784205

1.新建java测试类

2.创建配置文件applicationContext.xml

编辑applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">  
    <!-- 配置需要被Spring管理的Bean（创建，创建后放在了Spring IOC容器里面）-->
    <bean id="hello" class="ssm_springtest.testspring">
        <!-- 配置该Bean需要注入的属性（是通过属性set方法来注入的） -->
        <property name="info" value="Happy New Year!"/>
        <property name="name" value="april"/>
        
    </bean>
</beans>

新建testmain.java

package ssm_springtest;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class testmain {
	private String who = null;
	 
	public static void main(String[] args) {
		//获取Spring的ApplicationContext配置文件，注入IOC容器中
		//(Map: key:String, bean标签的id属性值 ==>value:Object, bean标签class属性所指类的实例)
		BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext.xml");
		testspring ts = (testspring)factory.getBean("hello");//map.get("hello")
		System.out.println(ts.getInfo());
		System.out.println(ts.getName());
		System.out.println(ts);
	}
}
