Spring总结实例之消息 事件
??? 今天看了美河夜色狼族的一集Spring视频，是关于Bean的高级部分：消息和事件。以前看书或看视频，只是看了却没有动手编代码，看后就忘了。
??? 前几天看到网友总结的自学经验，觉得说得很好，引文：光看别人骑自行车很容易, 那么是不是看了几百遍别人怎么骑自行车你也就马上能骑着走了呢? 不摔跤是不可能学会的。
??? 还有就是要经常总结：刚才说到会摔跤, 那么这时候就要总结遇到的问题, 这样下次再遇到就不会再去回忆了. 好记性不如烂笔头. 注释, 如果今天不写, 那么以后只会越来越忙, 以后再也没时间写注释了. If you doesn't have time to do it today, then when do you have time to do it tomorrow?
??? 所以今天就写个Spring的消息和事件实例。
1、JavaBean：User.java
package?cn.xy.hw;
/**?*//**
?*?@author?hanwei?*
?*/public?class?User?...{????private?String?name;????private?int?age;
????public?int?getAge()?...{????????return?age;
????}????public?void?setAge(int?age)?...{????????this.age?=?age;????}????public?String?getName()?...{????????return?name;????}????public?void?setName(String?name)?...{????????this.name?=?name;????}}2、用于国际化的两个消息资源文件：xiyou_en_US.properties和xiyou_zh_CN.properties
userlogin?user?...{0}?login?at?...{1}和
userlogin?使用者?...{0}?于?...{1}登入自定义下雨的事件：RainEvent.java
package?cn.xy.hw;import?org.springframework.context.ApplicationEvent;/**?*//**?*?@author?hanwei?*?*/public?class?RainEvent?extends?ApplicationEvent?...{????public?RainEvent(Object?arg0)?...{????????super(arg0);????????System.out.println("乌云密布、闪电、打雷，紧接着，下起了瓢泼大雨。");????}}下雨事件监听器：RainListener.java
package?cn.xy.hw;import?org.springframework.context.ApplicationEvent;import?org.springframework.context.ApplicationListener;/**?*//**?*?@author?hanwei?*?*/public?class?RainListener?implements?ApplicationListener?...{????/**//*?(non-Javadoc)?????*?@see?org.springframework.context.ApplicationListener#onApplicationEvent(org.springframework.context.ApplicationEvent)?????*/????public?void?onApplicationEvent(ApplicationEvent?arg0)?...{????????????????if(arg0?instanceof?RainEvent)...{????????????System.out.println("唐僧大喊："+arg0.getSource()+"赶快收衣服喽！");????????}????}}配置文件：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"????xsi:schemaLocation="http://www.springframework.org/schema/beans?http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">????<bean?id="user"?class="cn.xy.hw.User"?abstract="false"????????lazy-init="default"?autowire="default"?dependency-check="default">????????<property?name="name">????????????<value>hanweivalue>????????property>????????<property?name="age">????????????<value>20value>????????property>????bean>????<bean?id="messageSource"????????class="org.springframework.context.support.ResourceBundleMessageSource"????????abstract="false"?lazy-init="default"?autowire="default"????????dependency-check="default">????????<property?name="basename"?value="xiyou">property>????bean>????<bean?id="listener"?class="cn.xy.hw.RainListener"?abstract="false"????????lazy-init="default"?autowire="default"?dependency-check="default">????bean>beans>测试类：MianTest.java
package?cn.xy.hw;import?java.util.Calendar;import?java.util.Locale;import?org.springframework.context.ApplicationContext;import?org.springframework.context.support.ClassPathXmlApplicationContext;/**?*//**?*?@author?hanwei?*?*/public?class?MianTest?...{????public?static?void?main(String[]?args)?...{????????????????ApplicationContext?context?=?new?ClassPathXmlApplicationContext("applicationContext.xml");????????User?user?=?(User)context.getBean("user");????????????????Object[]?obj=new?Object[]...{user.getName(),Calendar.getInstance().getTime()};????????System.out.println(context.getMessage("userlogin",obj????????????????,"找不到指定模块！",Locale.CHINA));????????System.out.println(context.getMessage("userlogin",obj????????????????,"找不到指定模块！",Locale.US));????????????????context.publishEvent(new?RainEvent("下雨了！"));????????????}}OK了，这是运行测试类的结果：
使用者?hanwei?于?07-8-26?下午6:14登入user?hanwei?login?at?8/26/07?6:14?PM乌云密布、闪电、打雷，紧接着，下起了瓢泼大雨。唐僧大喊：下雨了！赶快收衣服喽！log4j:WARN?No?appenders?could?be?found?for?logger?(org.springframework.context.support.ClassPathXmlApplicationContext).log4j:WARN?Please?initialize?the?log4j?system?properly.?
1 楼 lizhaosuper 2007-08-27 可以把讲spring的是视频给共享一下不 2 楼 hanwei59 2007-08-27 这有美河的ftp地址，自己下吧。
