Hello Spring（5）ApplicationContext

Tester.java

package test;

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

public class Tester {
    
    public static void main( String[] args){
        
        /*Resource r = new ClassPathResource("beans.xml");
        BeanFactory factory = new XmlBeanFactory(r);*/
        
        @SuppressWarnings("resource")
        ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
        
        user.Dao dao = (Dao) context.getBean("userDao");
        dao.register( new user.Bean());
        
    }

}

换成这种写法需要增加两个 jar 包：

spring-beans-3.2.2.RELEASE.jar

spring-context-3.2.2.RELEASE.jar

这个方法常用。
