Spring aspect-Oriented Programming example (XML configuration form vs@ annotation form)

First, the XML configuration form

1. Add a facet-oriented configuration in the spring configuration file
The method in the slice class is executed when any method of the Com.activemq.service.impl.ConsumerServiceImpl interface implementation class is called.

2. Write Slice class

Attention:
1) can not do the Web layer (for example: com.activemq.action.ConsumerController) Proxy insert operation, the Pro-test is invalid.
(Before the web layer is considered invalid, in fact, is not, invalid because the slice configuration is located in the file, If it is spring-mvc.xml (SPRINGMVC profile), it is valid if it is not valid in Applicationcontext.xml (Spring configuration file). ）
2) <aop:pointcut> If it is in the <aop:aspect> element, the named Pointcut can only be accessed by the elements defined in the current <aop:aspect>. to be able to be accessed by all the enhancements defined in the entire <aop:config> element, you must define a pointcut under <aop:config>.

ii. @Aspect Annotated form

1. Configuration

Enable @aspect in spring configuration file Applicationcontext.xml and declare the notification class

<!---<id= "Aspectbean"  class= "Icom.axx.action.AopAspect"/><!----<  />

2. Write notification class
