[FIXED] How to know which Rest controller method called using HttpServletRequest or HttpServletResponse object?

Issue

I am using HandlerInterceptor (import org.springframework.web.servlet.HandlerInterceptor;) to get the Request and Response Attributes and Header information using preHandle, postHandle methods.

Now I want to know the name of the method called of Controller. Is there any way if we can get that info using HttpServletRequest or HttpServletResponse object ?

Solution

We need to use Object handler to get the details of method invocation. See the below code:

@Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
            ModelAndView modelAndView) throws Exception {

and

public static String getMethodName(Object handler) {
        String methodName = null;
        if(handler instanceof HandlerMethod) {
            HandlerMethod method = (HandlerMethod) handler;
            methodName = method.getMethod().getName();
        }
        return methodName;
    }
