package ch5.destroy;import java.io.File;import org.springframework.beans.factory.BeanFactory;import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;import org.springframework.beans.factory.support.BeanDefinitionRegistry;import org.springframework.beans.factory.xml.XmlBeanFactory;import org.springframework.core.io.FileSystemResource;public class TestSpring{ public static void main(String args[]) throws Exception{ //获取bean factory ConfigurableListableBeanFactory factory=(ConfigurableListableBeanFactory)getBeanFactory(); //使用子beanFactory SimpleBean bean1=(SimpleBean)factory.getBean("SimpleBean"); System.out.println("before destroy"); factory.destroySingletons(); System.out.println("after destory"); } public static BeanFactory getBeanFactory(){ //获取bean factory String realpath=""; //加载配置项 realpath=System.getProperty("user.dir")+File.separator+"src"+File.separator+"ch5/destroy"+File.separator+"applicationContext.xml"; ConfigurableListableBeanFactory factory=new XmlBeanFactory(new FileSystemResource(realpath)); return factory; }} |
结果：
this is info from afterpropertiesSet from SimpleBean
before destroy
this is info from destroy method
this is info from customer destroy method
after destory
