Springboot Facets Control business logic

Business logic: Write a public intercept class that filters the parameters passed into the controller

In order to invoke the interface security, each interface that needs to be called has a parameter Accesstoken for security validation

Note: First into the filter filters, then into the AOP, finally into the controller, we do things in the AOP filter controller parameters

Add: Interception naming rules brief

1) means matching all methods

Execution (* * (..))

2) means matching all public methods in the Com.savage.server.UserService

Execution (Public* com. savage.service.userservice.* (..))

3) represents all methods that match the Com.savage.server package and its sub-packages

Execution (* com.savage.server). *.*(..))
