Spring的事务机制

---恢复内容开始---

内定的=>(只需要在xml 中添加一个bean)

在xml 中添加

<bean id="listener" class="com.test.事件机制.listener">

</bean>

测试

public void listenerTest(){
AbstractApplicationContext aContext=new ClassPathXmlApplicationContext("bean.xml");
aContext.refresh();
}

public class listener implements ApplicationListener{

@Override
public void onApplicationEvent(ApplicationEvent arg0) {
// TODO Auto-generated method stub
if (arg0 instanceof ContextClosedEvent) {
System.out.println(arg0.getClass().getSimpleName()+"事实发生");
}

}

 

自定义事件==》

event:

public class myselfEvent extends ApplicationEvent{
String name;
public myselfEvent(Object source) {
super(source);

}
public myselfEvent(Object o,String name){
super(o);
this.name=name;
}
}

发布:

public class animal implements ApplicationContextAware{
private ApplicationContext ac;
private String sleepsString;

public String getSleepsString() {

ac.publishEvent(new myselfEvent(this, this.sleepsString));
return sleepsString;
}

public void setSleepsString(String sleepsString) {
this.sleepsString = sleepsString;
}

@Override
public void setApplicationContext(ApplicationContext arg0)
throws BeansException {
// TODO Auto-generated method stub
this.ac=arg0;
}

}

 

监听:

public class listener implements ApplicationListener{

@Override
public void onApplicationEvent(ApplicationEvent arg0) {
// TODO Auto-generated method stub

if (arg0 instanceof myselfEvent) {
System.out.println(arg0.getClass().getSimpleName()+"事实发生");
}else{
System.out.println(arg0.getClass().getName()+"other");
}

}

}

测试:

 

public void myselfListenerTest(){
AbstractApplicationContext context=new ClassPathXmlApplicationContext("bean.xml");
animal a=(animal) context.getBean("myselfListener");
System.out.println(a.getSleepsString());
}
