Spring Boot WebFlux | Global Exception Handling | Functional Endpoints | JavaTechie

This tutorial will explain you how to handle exception in Spring Reactive functional endpoint
As we all know, Error handling is one of the ways we make sure we handle our failures consistently. The benefit of handling exceptions globally is that we can customize all error output from our API into a single format that all consumers can understand and This will guarantee us easier and faster maintenance isn't it .

Ahhhhhhhhh, finally! Exception handling hs been Hard for me while learning functional programming. Thanks!!

[@tohirasadov689]

Finally! Best example. Best of all the best

[@AGAGARCIA]

Great Job. Thanks for share your knowledge.

[@arunpallayil9485]

Nicely done! Great explanation as usual! Thank you!

[@vishalkaushal4311]

You are seriously great. Hats off.

[@life.at_7000rpm]

In case the custom handler does not take effect, add @Order(-2) on your handler class to give it a higher priority than the DefaultErrorWebExceptionHandler.

[@kubickrock572]

Thank you man ! Great video.

[@leanaf]

Great tuto!! thanks man!

Superb brother as usual 👏 👌

Request you to please make some content explaining Spring Api Gateway vs Kubernets Ingress. Which one should we use? Or can we use both together ?

[@amazingboy8860]

You are awesome sir

[@malleswarrao3887]

Super

[@ajisegirisunday2885]

Thanks you are the best... Please can you do a video using hibernate with spring webflux 🙏

[@Javatechie]

Hibernate?

[@ajisegirisunday2885]

@@Javatechie yes please. reactive hibernate

[@kumarguru3044]

Can you also explain about both WebClient and rest template which is used to call from one rest service to another rest service

[@ayushmittal7059]

Thanks a lot , it was really helpful also can you help in writing the unit test cases of these 2 classes that exception handler and global error attributes as for my project only 3% coverage is there for these 2 classes

[@Saravanan-lj9so]

Great.In the real time every one use storedprocedure call for database. Can we call sp from reactive program?

[@Javatechie]

I guess yes we can but let me check

[@malleswarrao3887]

Can you please tell me how can I validate the model data in reactive programming

[@faithfulolaleru7255]

this saved me a lot of trial and error, thanks. But quick question, instead of having one fixed status of bad request in global error attributes, how can I make it dynamic so when I throw a new exception, I can pass along the status I want with it, be it 404 not found or 401 unauthorized

[@Javatechie]

You can use @ResponseStatus annotations

[@faithfulolaleru7255]

@@Javatechie thanks for the reply, I've read on the annotation and still a little bit confused. After putting the @ResponseStatus on the different exception classes, in the getErrorAttributes(), we are hardcoding the fields to be returned, how can I make those fields change their values i.e I added a statusCode field that I want to display with my error response, how can I update it in getErrorAttributes() based off what exception is being hit?

[@Javatechie]

No buddy how it's hardcoded . To make it dynamic better to create multiple exception class use one for 400 and different for 500 like that

[@faithfulolaleru7255]

@@Javatechie I have multiple exception classes with different responseStatuses, but check 17:35, it'll always return bad request regardless of which exception class it hits. So in getErrorAttributes() (check from 24:45) , I added an httpStatus field to my map, that I now get in the exceptionHandler to set the status. So my question now is, how to I change the httpStatus field in getErrorAttributes() to change depending on which exception is hit in the application

[@SatyaPrakash-gj5vp]

Could you please make a a video on ReactiveSecurityContextHolder

[@Javatechie]

Okay i will do that

[@harshverm776]

Hi, It is looking bit tough then our traditional rest endpoints. Could you please suggest some topic to learn this Functional Programming ?

[@Javatechie]

I would suggest you to be a master in java 8 before start reactive functional programming

[@harshverm776]

@@Javatechie Okay, but I am already having knowledge of Java 8.

[@Javatechie]

Then you can easily grab a reactive functional style of coding. Keep practicing

[@harshverm776]

@@Javatechie Okay, Thank you.

Video quality not good.

Hello buddy apologies for this please increase the resolution. Since this is the old video resolution Ava up to 720 HD. All recent videos are available in 4k

this shows how slow working with java is
