The project willl log the requests coming to BookingController resource.
We have provide three public api
1.) Default Home Page which is residing under "/hotel/" path. 2.) GET Request (residing under "/hotel/book" path) : which will retrive the customer information based upon the input supplied. We are expecting id of customer record. which can be used to fetch the information from db (if required). But we have generated the required customer information at controller itself (by generating UUID string and sending it back) 3.) Post Request (residing under "/hotel/book" path) : Post request will post the customer information like name, city, purpose, idproof etc to the server module.
We have created one LoggingHandler aspect which will intercepts all the above three requests. The LoggingHandler aspect have mainly four methods 1.) logBefore : logBefore method will be executed once it satisfied its pointcut expression. logBefore has pointcut expression @Before("controller() && allMethod() && args(..,request)"), which implies it will be executed for 1.) Controller module 2.) All Method of module 3.) Method taking HttpServletRequest as last parameters So, Joining above three points, In controller module there are only two methods which are taking HttpServletRequest as last parameters, so GET and Post methods of "/book" resouce of BookingController will be intercepted by logBefore and will log all the information.
2.) logAfter : It has pointcut expression"@AfterReturning(pointcut = "controller() && allMethod()", returning = "result")", Which means it will be executed for all resources of BookingController name ("/","/book" (GET,Post)) 3.) logAfterThrowing : logAfterThrowing will be executed if any method of BookingController modules throws any exception. 4.) logAround : logAround will be executed for all methods of BookingController controller module. We have used it to calculate the execution time of particular method.
Our server application is deployed in local machine so "localhost" is our machine name and at port 9095. Please change your ip and port to access the resources of BookingController.
The URL to access the resource should look like.
http://:/log/hotel/
Here are the execution results:
