I'm trying to implement Error handling into my Rest API and testing with Postman, when I give an incorrect path postman returns a 404 but its a 404 HTML. I am using the #ControllerAdvice for the global exception handler.
the #ControllerAdvice class is RestResponseEntityExceptionHandler.java
#ControllerAdvice
public class RestResponseEntityExceptionHandler
extends ResponseEntityExceptionHandler {
#ExceptionHandler(value = { IllegalArgumentException.class, IllegalStateException.class })
protected ResponseEntity<Object> handleConflict(
RuntimeException ex, WebRequest request) {
String bodyOfResponse = "This should be application specific";
return handleExceptionInternal(ex, bodyOfResponse,
new HttpHeaders(), HttpStatus.CONFLICT, request);
}
}
I was told that by default spring boot should return something like this
{
"timestamp": 1436442596410,
"status": 404,
"error": "Not Found",
"message": "No message available",
"path": "/item"
}
the nonexistent path I give it is
http://localhost:8080/Assignment2C/breweriessdfsdf
the response I get is

404 means that spring mvc has failed to find the appropriate end point (controller + method) to run your request.
#ControllerAdvice is relevant only if the method has actually been called and there was an exception. But in your case the flow doesn't even reach controller that's why controller advice doesn't work.
You can customize the error page by creating a controller the implements ErrorController.
This information does not strictly answer the question, but I realize that that's what you really need to resolve the issue so I'll just post a link to the relevant tutorial.

I am doing a simple example using ESPAsyncWebServer on ESP32. In this context I wrote a html file (there are a slider and a button) and tested it on a browser until the content look well. Then I integrate it in the C++ source code for ESP32. It works and look as expected until I don't add a callback to read the value of the slider.
This is the complete source code:
#include <Arduino.h>
#include <WiFi.h>
#include <AsyncTCP.h>
#include <ESPAsyncWebServer.h>
// Replace with your network credentials
const char ssid[] = "Vodafone-A40881218";
const char pswd[] = "rJbFMktHCcqN67Ye";
const int output = 2;
String sliderValue = "0";
// setting PWM properties
const int freq = 5000;
const int ledChannel = 0;
const int resolution = 8;
const char* PARAM_INPUT = "value";
// Create AsyncWebServer object on port 80
AsyncWebServer server(80);
#if 0

I found the problem. The author of ESPAsyncWebServer decided to use the % character as the delimiter for placeholders for the template processor. Unfortunately, the % is quite common in CSS and JavaScript so, writing CSS and JavaScript in HTML file(s) or Strings does not work as expected because the wrong interpretation of % as delimiters of chuncks of text that are not placeholders but CSS or JavaScript code. At the moment there is not a workaround, just do not use % in CSS and JavaScript.
I had the same problem and I fixed it by changing the delimiter character (%) to a ($).
To do this you have to modify the definition of "TEMPLATE_PLACEHOLDER" which is in the file "ESPAsyncWebServer\src\WebResponseImpl.h"
#ifndef TEMPLATE_PLACEHOLDER
#define TEMPLATE_PLACEHOLDER '$' <<<<
#endif

Please check if your controller class is within source package (Package in which class with #SpringBootApplication exist ). If not, Add #ComponentScan annotation along with #SpringBootApplication to make sure your controller class is being scanned for endpoints. It's often an issue to me to!
I am doing angular quick start tutorial.
So I am just Hero tutorial that specifies in angular2 quickstart on its website.
That runs fine for me. it binds static array data and perform CRUD.
But now I want to learn how to call web API method for getting data from database.
So I am calling webapi method in getHeroes() method of service and calling that method from init method-ngOnInit() of component but it gives error like this.
please correct if I am wrong.
Got this error, while calling Web api controller from my service in angular2

you may try below,
Angular version < RC5
include HTTP_PROVIDERS in the providers array of Component metadata.
Angular version >= RC5
import HttpModule in the Module containing your component.
Hope this helps!!
With Entrust, I implemented how user will be redirected to his own dashboard after login by adding this method in Authcontroller.php
protected function authenticated()
{
if(\Auth::user()->hasRole(['super_admin',]) ) {
return redirect('/dashboard');
} else if(\Auth::user()->hasRole(['staff_admin']) ) {
return redirect('/staff/dashboard');
} else if(\Auth::user()->hasRole(['subadmin_admin']) ) {
return redirect('/subadmin/dashboard');
}
}
What challenge I am facing right now is, for eg. if staff had logged in and redirected to his dashboard as
domain.com/staff/dashboard
but if he manually deletes the staff from url and tries to access Super-Admin Dashboard then Entrust throws 403 Error, but I want to redirect him to his dashboard, with message that " You are not authorized".
I tried to implement same code in RedirectIfAuthenticated middleware, but it gave error as hasRole called on Null.
Your DashboardController add constructor.
Example Code
class UserController extends Controller
{
public function __construct()
{
$this->middleware(['role:super_admin']);
}
public function index()
{
return view('dashboard');
}
}
Then, error folder add 403.blade.php like so:
