thank you so much😊
So so so helpful, sir!! Thank you very much 🙇♂
Excellent explanation
Thank you brother 😊
Thank you so very much. This was exactly what I needed.
Thanks very much for this great lecture
Thanks Basant !! Awesome explanation on the implementation with example
Its really a great tutorial...... and you present very well.
Great explanation !! All concepts clear!! Keep it up Java Techie sir!! Thank you...
Great explanation and we are able to understand easily. Thanks a lot!!
Very helpful video. Thanks for your films :)
Me salvaste el día bro, muchísimas gracias :3
Nice video exactly what i looking for ,it will be good if you add also one more condition "sorting with multiple column" but thats fine
Very good explanation. Thank you for the video. This is helpful in my work.
Wah! What a content..... TQ Basant...
You explained so nicely
As always, best content
smart work and great java techie
Thank you boy
You're perfect
Awesome as usual 😊
Thank you so much friend!
excellent explain thanks man.
Thank you so much 👍
Thank you sooo much sir🙏
Полезный ролик, спасибо.
Excellent video Basant
Thank you so very much!
Very clear explanation 👍
Thank you, Basant. Can you please make a tutorial on Isolation and propagation in Spring Transaction
Yes. I'm also waiting for this topic.
thanks,vary helpful
Good explanation on the implementation of offset pagination in Spring. However, please use query parameters in the controller end instead of path variables. Query params are meant for filtering, sorting, and pagination.
Agree with you 😊
Awesome content brother.
thanks very much!!
Good one Bro. It would be great if you have added below as part of the video
1. how offset is calculated internally by spring
2. Desc by field
I explain this how offset calculated
You are a super man bro
Simply awesome. Our ye dislike kon karta hai .
awesome video!
How counted totalElements in json? It's second internal query 'select count(*) over()' ?
thank you very much
Java Techie is great !!!
Thanks brother.
Good Content 👌
nice explanation
Boss u r great
Good video for learner and professional also..
Thanks sir...
Can u make the video related to data transaction concepts of propagation and isolation and other stuffs.
Awesome
Thank you.
Thanks awesome
Thanks...
That's i asking for some time before in comment...
Yes Sahil and was noted this
Best video !!!!!!!!!!!!!!!!!!!!!
Respect ++!
good video, can you please explain about APIResponse how it works on multiple types (T)
Thanks!
Thank you
With findAll, we can use pagination bcos it has overloaded method but what if there is custom method? How to use pagination?
Make video on filtering using jpa specification.
Thanks
Tutorial on isolation n propogation please
Thanks for this @Javatechie, and I would like to know how you have implemented this in the UI screen level. Is it possible for you to share those with me?
Hi Bro,
In controller class at line "new APIResponse(allProducts.size(),allProducts) " I am getting below compilation error
CANNOT INFER TYPE ARGUMENTS FOR APIRESPONSE . Please help me how to resolve this
Just want to call out couple of things. Sorting field, page size and offset are usually accepted as query params and not the path params. Path params are used for resource ids.
Yes agree 👍
@@Javatechie is it okay to used request param for the offset and page size instead of Pathvariable in controller?
@@Javatechie how did you make it appear the page,sort etc on the end part of your api response in postman?
This response is part of pageable
@@Javatechie what do I do to make it appear in postman? Basically, I got the exact response even the limit but that endpart of pageable won't show in postman..😭
how can we implement pagination and filter with dynamic JPA/native query
thanks boss
As I'm understanding the last example, PaginationAndSort first sorts all records, then paginates the result. This is what I would want and expect.
Sir, Plz make one video of, how to handle springboot backend exceptions propagated on Angular front end side, and you want to display different errors in angular page to end user.
Plzzz make vedio with the same concept with the help of using criteria api means creating our own user repository and providing implement for that with the help of criteria builder , without extending jpa r crud repository
❤️❤️
Does anyone know if Pagination works similarly with Spring JDBC or Spring Data?
nice
Nice explanation. But I have a question here. If in pagination, suppose the first page shows records from id 1-10 in asc order. So as per this logic will that not alter the results shown in the first page if the sorting is applied to descending?
Yes it will vary
whoa this is really easy to understand! I have one more question though, what if i want to sort and filter a field with value...
let's say we have a field called inventory and i want to filter the data that has < 5 inventory ?
It's simple right call findAll and sort by field which you want. That's what I have explained please check once
Hi @basant, one query. Based on offset and page size we will get records. Ex 0 , 10 = 10. But as u showed in the front end how can we show the total records size like 20-30 of 200( this 200 total size). So that if we r at last page we should disable the next page button.
You need to set pageSize and total record count to disable next button once it fetches all
Pagination will only work with predefined queries ?
Or does it work with our custom named queries as well ?
Yes it will work with custom query as well
Instead of passing page size and offset, can we just see the hard coded 5 no. of elements in one page and click enter and then see other pages one by one till end?
That you need to customize in code . On click next increase offset count to +5
Can you also make a vedio in UI side as well and.consume this same application and show us how this works please
Okay I will do that
@@Javatechie still waiting..???
If you have null values in db table column. Here how you will sort data in query?
That's bad practice right? Why should you keep null value in db
Hi Brother,
I have tried to implement same, but not able to get PageRequest in my project. Please let me know how to add dependency in my projejct?
Thanks & Regards,
Kiran Mandarapu
This is latest feature of spring data jpa PageRequest should be available .not sure if they introduced any new class.just check spring data official page
Which font you are using in the INTELLIJ bro it's awesome
I am using normal intellij font which is default one .
i also use postconstruct
but after run the application data is not created my sql table
can u plzz explain
how to resolve this problem
or we manually insert data
Please configure Lombok in your ide
I have 137 data in database and when i entered api/3/50 it should show me 37 data but it shows me empty content[]. what will i do?
it will show you the data from 151 records if it is available
If sorting is not used in pagination will it alter the result if hit multiple times suppose say in page0 A,B came and again query hit with page1 B,C came so here B came again. Is it the possibility?
No it won't
@@Javatechie but if data keeps getting added then?
Which happens first , pagination or sorting ?
Pagination, just debug the flow you will get it
How to implement UI for this server side pagination and sorting like you showed in this video? Is UI code is also shared?
No UI code not shared . Did you find any difficulty while implementing
@@Javatechie Actually i am in learning phase so i am not aware of implementing rest client with Angular or React..
Can you share the same if possible? i need this in angular. Thanks in Advance
Saud cool before you learn this pagination Full stack development , i would strongly suggest you to checkout my spring boot angular crud video because you will understand how to do this frontend and backend Integration
Link for your reference czcams.com/video/QV7ke4a7Lvc/video.html
@@Javatechie Thanks Basand ji.. I appreciate your efforts.
can we using jQuery datatables on frontend?
Yes we can use that
Is it possible pagination start from 0? I saw some properties but didn't work that
Yes that's what I explained
@@Javatechie sorry bro i meant 1, default 0 is it possible to change 1?spring.data.web.pageable.one-indexed-parameters=true. This was I tried. It works but we need to recive as Pageble in parameter. But in my case I can’t give that need to build pageble using pagerequest that time it’s not working
Not getting you man .
How to consume all the data from paginated API via rest template
RestTemplate.getForObject() will work . Did you faced any issues
Yeah I am facing issue I have paginated api which gives 500 response at a single post request this post request I need to pass query param page no and page size and header with content type,jwt token , accepted language please help how can I consume all the response data
Thanks sir for this great explaination.
But I am receiving "[ ]", when I retur the Page object as response.
When I pass the List of contents inside the Page as response I get the data, but when I return the object of Page i get "[ ]".
What could be the reason, please help.
Use below poc
public Page getProductsWithPageResponse(int offset, int limit) {
return repository.findAll(PageRequest.of(offset, limit));
}
@@Javatechie I am doing the same thing,
->This is my Service method,
public ResponseEntity getUserBooks(int offset, int pageSize,Long user_id) {
try {
User user = userRepo.getReferenceById(user_id);
Pageable pageable = PageRequest.of(offset, pageSize, Sort.by(Util.SORT_BY_TIME));
Page books = bookRepo.findByUser(user,pageable).map(Util::bookToDto);
return new ResponseEntity(new APIResponse((int)books.getTotalElements(),books), HttpStatus.OK);
} catch (Exception e) {
System.out.println("exception"+e.getMessage());
return new ResponseEntity(new APIResponse(0,Page.empty()), HttpStatus.INTERNAL_SERVER_ERROR);
}
}
-> This is my repository method
Page findByUser(User user, Pageable pageable);
Are you fetching a single object
@@Javatechie No sir,
When I logged the Page object, i can see the content list with all the object of type BookDto, along with other details of the Page object. I am trying to get Page type object which i then map to Page type object.
I tried to use Gson to convert the Page object to json string and pass that string, although this thing worked, i could see the content list in my json. But some of the attributes were missing from the json like, 'last','totalPages' etc. But you are getting all the attributes there, @15:47. And I think using Gson isn't the best practice.
I searched through stackoverflow and found the same problem, but each time i paste the link here yt, removes my comment, so can't add that link.
.withSort doesnot found
how to solve it?
Not sure what spring boot version you are using just check jpa official documentation they might change the method name
可惜没有中文字幕
11:55 is the core point
Thanks
