Tester.java

1 package test; 2  3 import org.springframework.context.ApplicationContext; 4 import org.springframework.context.support.ClassPathXmlApplicationContext; 5 import user.Dao; 6  7 public class Tester { 8      9     public static void main( String[] args){10         11         /*Resource r = new ClassPathResource("beans.xml");12         BeanFactory factory = new XmlBeanFactory(r);*/13         14         @SuppressWarnings("resource")15         ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");16         17         user.Dao dao = (Dao) context.getBean("userDao");18         dao.register( new user.Bean());19         20     }21 22 }

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。
