Excellent

[@Justadudeyes]

Wonderful video!!!!

[@samirmujawar9703]

good work bro. awesome !!!

[@林可可-l9w]

for the Mono scenairo, even you omit an exception, according to the diagram, onNext() still should be invoked, why no statement printed?

[@andreicapi3535]

Thank you this cleared up alot

[@jiangfengji7931]

看了一下午的国内视频晕晕的，直接这样来个demo多好

[@李卓轩李]

it's nice , thank you

[@deepakmishra169]

Very nice 👍👏👏👏

[@saymumsany]

Please provide a practical demo like how this web flux will use in web application or API service.

[@surajJr24]

It is good to convert the mono to string using block?

[@Javatechie]

If you will use a block then it will not be considered async right?

[@TheGodfather101]

block() is like when you call get() or join() on an async/await in js. only when you dont have any preceeding tasks to do and can afford doing blocked retrieval.

[@yogeshjangra3603]

Nice Explanation, Suggestion : Intro music is too irritating due to high volume..

[@Javatechie]

Not sure it might be an editing mistake

[@samuelsodagudi]

Thank you. 👌👌👌👌👌

[@kavikavitha2158]

[@HelloWorld-id5ho]

which springboot assistant plugin u r using?

[@nareshkumar-fm1wf]

Hi which intellij idea u r using

[@Javatechie]

Community edition

[@nareshkumar-fm1wf]

How will add spring assistant

[@Javatechie]

Now search plugin for spring initializer

[@mntube8]

Difference here is that in case of Mono.error there is no onNext call while in the case of Flux.error, the onNext call is happening before the onError call.

[@chandrasahoo8623]

Why There is no onnext method call in case of exception in mono but we had onnext method call in case of exception in flux

[@dineshreddyambu]

is it possible to convert Mono object to java object without blocking ?

[@Javatechie]

No not possible

[@dineshreddyambu]

I have one uses case . I am calling multiple webclient call synchronous and return to graphql response . While return to graphql I am converting to mono object to Java object through completable future but we are getting time outs . I don’t want design change here . Could you please suggest for the next step

[@Javatechie]

Can you try one solution from the mono object call toFuture().get()

[@dineshreddyambu]

@@Javatechie I have tried that also but without future is any another way?

[@siddhilalabobo3597]

Hi Java Techie, great video, one question, can we return .json file with Springboot, suppose user input to API and API will return .json or .text file .Thanks in advance

[@Javatechie]

Yes we can do but you need to return byte[]

[@siddhilalabobo3597]

@@Javatechie Thanks a lot

[@coolfreaks68]

Yes Madam. You have to covert your file content into a Byte array, and write that to the HTTP response output stream. Also you have to mention the response content type and the filename. You may write you code in the following way : @RequestMapping(value = "/download", method = RequestMethod.GET) public void downloadPDFResource(HttpServletRequest request, HttpServletResponse response) { //Setting response content type response.setContentType("application/vnd.ms-excel"); //Setting Filename - the filename may also be derived dynamically response.setHeader("Content-Disposition", "attachment; filename=\"Sales_Group_Inbound_Data.xls\""); .HSSFWorkbook wb = new HSSFWorkbook(); /* Here you may initialize your work book object using hssf library*/ ByteArrayOutputStream outByteStream = new ByteArrayOutputStream(); // At this line the excel file gets written to ByteArrayOutputStream wb.write(outByteStream); byte[] outArray = outByteStream.toByteArray(); OutputStream outStream = response.getOutputStream(); // At this line the Byte Array gets written to HttpServletResponse output stream outStream.write(outArray); outStream.flush(); }

[@coolfreaks68]

Response content type of an endpoint will have nothing to do with Spring Boot. Spring boot is about the initializing and running the application.

[@ModifiedGaddiyan]

Test is not working on my machine what to do to run Monoflux

[@Javatechie]

What is the error

[@jagadeeshbelagallu5243]

How to contact Java Techie trainer i have some realtime doughts is there and i am facing difficult in implimeting code in office

[@Srini8174]

Thank you

[@raghuvardhansaripalli9636]

Hi , can you pls create a video on Exception handling with spring weblux. i am searching in youtube, i am not getting any good videos. PLEASE PLEASE do this whenever you have time.. In netty server, 5XXError has been removed and its not working. thank you , God bless you and Stay Safe..

[@Javatechie]

Okay I will do that

[@raghuvardhansaripalli9636]

@@Javatechie Thank you Basant for your quick reply. your fans including me will be thankful if you can create video something like this whenever you have time: 1. creating a repository, service, controller classes with Mono & Flux class using mongoDbreactive DB. 2. then handle different types of expections like 404, 500 Exceptions, NOT_FOUND etc. from controller class by using @AdviceController or any other approach. 3. you are the best person to take a call to handle global exceptions FOR WEBFLUX. thank you in advance, GOD BLESS YOU...

[@raj006]

In real applications subscribe() method is prohibited from using as it blocks the flow which is again asynchronous execution

[@rameshbabuarigela9902]

What is the difference between spring boot and spring webflux ? Can anyone please explain?

[@elonmusk4687]

What is the name of this ide?

[@johnnesjeandesouzasilva3845]
