XML file configuration in spring implements AOP

The configuration file differs greatly from the way annotations are, with many more configuration items.

Pointcut syntax definition for facets

• Intercept all the methods under Test.spring.service.impl.PersonServiceBean
  expression= "Execution (* test.spring.service.impl.personservicebean.* (..))"
  
• All methods of intercepting all classes under the Test.spring.service.impl sub-package
  expression= "Execution (* Test.spring.service.impl). *.*(..))"
  
• Block all methods that return a string type under Test.spring.service.impl.PersonServiceBean
  expression= "Execution (java.lang.String test.spring.service.impl.personservicebean.* (..))"
  
• Block the first method in all methods under Test.spring.service.impl.PersonServiceBean that has a parameter type of string
  expression= "Execution (* test.spring.service.impl.personservicebean.* (java.lang.String,..))"
