Service Interfaces to Ixxxservice form, and service realization is xxxservice, this is the protocol design

steps:

1.e:\users\workspaces\kmwalletapp\spring\aop\test\helloworldservice.java Inheritance (implements) XX Interface

2.e:\users\workspaces\kmwalletapp\spring\aop\test\ihelloworldservice.java Defining interface Methods

3.HelloWorldService Implementing interface Methods

E:\Users\WorkSpaces\KmwalletApp\spring\aop\test\HelloWorldAspect.java defining Facets

E:\Users\WorkSpaces\KmwalletApp\spring\aop\test\AopTest.java Test Run
