Get Request/Response Body&Header in Spring AOP - spring

Question

I want to get request/response body and header within my aspect before and after if it's available or how to get those .
I mean i think with before annotation should be work for request,
with after annotation should be work for response. Can be ?
What I've tried so far :
I tried logbook library it's very complicated for me i could'nt figured it out how to work with that.So i gave up.
The actuator can do trick but I am doing extra work like how many times the endpoints called etc.So therefore i can't use actuator.
Also i tried to get request headers like below at least but i think this headers coming same all the time.I couldn't get httpservletresponse like how httpservetrequest does.
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes())
.getRequest();
then
request.getHeader("date") but what about requestbody ?
how to get requestbody ? responsebody ? repsonseheader ?
My aspect file :
#Aspect
#Component
public class AppAspect implements ResponseInfo{
#Before("execution(#(#org.springframework.web.bind.annotation.RequestMapping *) * *(..))")
public void loggingStartPointRequests(JoinPoint joinPoint) {
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes())
.getRequest();
}
#After("execution(#(#org.springframework.web.bind.annotation.RequestMapping *) * *(..))")
public void loggingEndPointRequests(JoinPoint joinPoint) throws IOException {
}
}
My Controller Class:
#RestController
public class MainController {
#GetMapping("/people") //
public ResponseEntity<Poeple> getAllPeople(#RequestParam(name = "page", required = false) Integer page,
#RequestParam(name = "size", required = false) Integer size,
#RequestParam(name = "sortBy", required = false) Boolean sortByNameOrEpCount) {
doSomething();
}
}

Answer 1

I had the same problem and if you have your #Aspect annotated with #Component (or any #Autowired candidate) you can simply get the HttpServletRequest like this:
#Aspect
#Component
public class SomeAspect {
#Autowired
HttpServletRequest request;
#Before("...")
public void beforeAdvice(JoinPoint jp){
/* You will have the current request on the request property */
System.out.println(request.getRequestURL());
}
}
I know this is an old question but I hope it'll be helpful.

I think what you need is to implement the interface HandlerInterceptor, it would help you being able to inspect the request and the response. For example:
public class ApiMonitor implements HandlerInterceptor {
#Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) {
// when the client access to your endpoint
}
#Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) {
// when you finished your process
}
#Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) {
// after you already returned an answer to the client
}
}
If you want to operate with the object that you're returning just before you send it to the client, then you need AOP, yes. That's an example of how I do it to modify an object on certain endpoints just before it's parsed to json.
#Component
#Aspect
public class MyCustomAOPInterceptor {
/**
* These poincuts check the execution of a method in any (*)
* class of my.package.controller and that start with
* get/list/find plus any other word (*) . For example
* my.package.controller.UserController.getUserById()
*/
#Pointcut("execution(* my.package.controller.*.get*(..))")
public void petitionsStartWithGet() { }
#Pointcut("execution(* my.package.controller.*.list*(..))")
public void petitionsStartWithList() { }
#Pointcut("execution(* my.package.controller.*.find*(..))")
public void petitionsStartWithFind() { }
#AfterReturning(pointcut = "petitionsStartWithGet() || petitionsStartWithList() || petitionsStartWithFind()", returning = "result")
public void translateEntities(JoinPoint joinPoint, Object result) {
// do your stuff; result is the object that you need
}
}
