Thank you so much for this for months i couldn't exactly understand how to use controller advice and exception handler this tutorial was really helpful.
Hi Nelson! Great course. I would also like to ask what's the better way to have exceptionHandlers with several httpstatus codes covered (400, 406, 409 etc.) . Should "handleApiRequestException" be parametrized or what would you recommend?
9:45 You can also use the wrapper for Response Entity's BAD_REQUEST: return ResponseEntity.badRequest().body(apiException); // instead of return new ResponseEntity(apiException, badRequest);
I like the way spring handles Exceptions, I looked up ControllerAdvice and found a nice guide for it on springs official documentation. Here are few annotations for exception handlers that are quite useful too * @ResponseBody -> allows you to return whatever you want in response body * @ResponseStatus -> specifies response status In fact, I think that you should include this annotaions in one of your videos too, because they're very easy to use and helps u to get rid of some boilerplate
I appreciated this effort but many RUclips's have done this. Can you show handle positive/negative responses. How to catch and re-throw exception in rest api consuming application
Very nice video that explains exception handling suucinctly. For validation error in request payload I need to show the client the details of the validation error. Throwable is bit clumsy. Please suggest
it's very kind of you to show us the exception handling practice, but i have no idea how to define the business exception, eg: DataAlreadyExistException or NoPermissionException； if there are many many business operations, there will be lots of exception classes; do you have any method to deal with it？ looking forward to seeing your response; thanks
Thanks a lot. That was really good explanation. What would really useful is, to demonstrate how to actually handle the exception instead of forcefully throw the exception from controller. There is one more way if you can make a video on that handleExceptionInternal from org.springframework.web.servlet.mvc.method.annotation which also returns the ResponseEntity, really appreciate your efforts for making these videos.
But the controllerAdvice is for general exceptions (all your app) why does not use a specific package or even use RestControllerAdvixe for capturing the body and then customised it?
Hi, how can I get my exception to be traced all the way back to postman? I didn't manage to get the message "email already taken" in Postman, all I get is a 500 Internal Server Error
Thank you amigos, that was great! Just, don't we need to try catch the errors with exceptions? I thought that was mandatory to use try catch method... Thanks!
If it was a plain vanilla java project then an uncaught error would crash the program. In a java web server, an exception will be shown as an error to the client that issued the requested which resulted in an exception but it does not crash the server.
Well, your videos are easy to understand. Could you make videos about redis and mysql, like read from redis, and write into redis and mysql, how to keep data in redis and mysql synchronized.
Why we don't send the Throwable to clients, we can see the problem directli ? maybe with the complete message ex.printStackTrace() in a specific attribute descriptionError
How can we handle exceptions in micro services? If one micro service throws an exception how can we handle that in another microservice using this mechanism?
amigoscode, sorry to bother you. I've got a question. I'm a bit of a newbie when it comes to Java. Just finished Herbert Schildt's "Java A Beginner's Guide" and don't know where to go next. I wanna get into Android but I'm missing plenty of knowledge of Swing, Web Services, Data Structures, Database connections, etc. Is there a good series of books and/or courses you could recommend to me? I've been doing PHP and Javascript for a long time. But no up to date techniques. That's my background if it's of any help.
Hi Valdez, If you want to get into Android development I recommend you learning Kotlin and maybe good to know Java. No one uses Swing. Data structures you will learn them as you need them. But 90 percent of times you will use Lists and Maps. so I would not worry about it. For Android you need to know how to use the SDK, Animations, Rx Kotlin/Java, Realm... Also focus on one thing and don't try tol learn a millions things. If its Android you want to do then learn Kotlin/Java. Does this helps?
@@amigoscode a little. I really want to become a Full Stack web developer since the sites I mantain at work are quite old. Any pointers when it comes books or courses?
I need to create a custom exception with more attributes than the offered in super constructor (an error code for example). What's the best approach to do it.
where does he handle the exceptions? cause i get the error "unhandled exception". try catch isnt working because its not ending the methodand return my exception. and he is not adding it to the method signature to deal with it... any help?
Thanks Bro for The lesson , but can you tell me how to get that api in react , using Axios/fetch or anything else cuz when i try that on react it keeps showin me 500 internal server error and i got no message , only got that message from intellij console
You might as well wear a cape and start going around places. Your explanation is simply supreme man.
It's very easy to understand what is going on, your style of explaining is a A+!

what a beautiful and easy tutorial. Thank you Champ
I appreciated this effort but many RUclips's have done this. Can you show handle positive/negative responses. How to catch and re-throw exception in rest api consuming application
What would really useful is, to demonstrate how to handle exception during our project is running. It is very understandable for every developer.
Love you amigos, you have very comprehensive Spring Boot videos! How do you run the React front end and the Java back end on the same port?
I have a course on my website doing that
Very nice video that explains exception handling suucinctly.
For validation error in request payload I need to show the client the details of the validation error. Throwable is bit clumsy.
Please suggest
Nice video, next time can you please show us how to create a fronted for the springboot api using ReactJS?
It was helpful, as always got what I needed. Thank you for solid stuff.
hi, thanks for the video. On question: why are you using extends RuntimeException at 01:33 , instead of extends Exception. thanks
it's very kind of you to show us the exception handling practice, but i have no idea how to define the business exception, eg: DataAlreadyExistException or NoPermissionException； if there are many many business operations, there will be lots of exception classes; do you have any method to deal with it？ looking forward to seeing your response; thanks
You should not have a customer exception for everything. Try make it as generic as possible
Thank you so much this really covered a lot
This really helped me out thank you

Did you find how to do it ? Can you tell
Hey mister, could you please share how to do same but without spring boot ? Just spring mvc 5?
Well done! Thank you very much
Thank you, Nelson!
That is pretty well explained , thank you very much
Good teaching. Good creativity. Thank you a lot!
Do we always need 3 classes to throw a customer exception.?
Hi Nelson , i think we can put this exception handler inside the service service ?
Thanks, that was very helpfull
Simple and super useful !
But the controllerAdvice is for general exceptions (all your app)
why does not use a specific package or even use RestControllerAdvixe for capturing the body and then customised it?
What video recorder you use in mac? please
Asalam walequm, Kindly describe video how to handle many exceptions with code, Jazak Allah

Very helpful, thanks 👍
Whas it the best practice to manage your message in one
file , profile file? or something likely enum types?
Didn’t understand your question
Thank you amigos, that was great!
Just, don't we need to try catch the errors with exceptions?
I thought that was mandatory to use try catch method...
Thanks!
Thanks No it’s not

Hi, can you please make exception handling video for spring integration. In Spring integration, @ControllerAdvice doesn't work
what is the functional counterpart of this (not aspect oriented like this)?
Thanks bro!
Any idea how to tackle this when using Spring Reactive and WebFlux?
Tackle what?
why throw BAD REQUEST every time I dont get it
Why not get the status from the exception that you defined a getter for instead of defining the variable.
i followed the same example but i'm getting an internal server error and its says "could not find acceptable representation" any idea?
How can we handle exceptions in micro services? If one micro service throws an exception how can we handle that in another microservice using this mechanism?
Hi , nice explanation but why did you passed the Http Status 2 times in the controller advice
Man, if you found out that, please tell me. I have the same question now.
Can you please link the previous video that shows how you got here?
here: amigoscode.com/courses/spring-boot-fullstack
This does not work for me, I had to have the controller extend the customhandler class before it work. I'm using spring tool suite 4.6.
Thanks
Thank you
Awesome...! Thanks a lot

I am not getting what I declared in controller advice.. it is throwing internal server exception
i just get the message "Request failed with status code 400", but did everything like described. Does anyone has an idea whats the problem?

You don’t have too coz that’s internal server you will get that by default
