Create a GraphQL Client in Java with Spring Boot

If you're working on a Spring application and you need to call another REST API, you have tools such as RestTemplate or WebClient. But what if you need to call a GraphQL API? With Spring, a GraphQL Client is available. In this tutorial, you will learn how to include it in your project and use it by building a practical example.

Hello Dan,

To be honest, your YouTube channel is one of the best for Spring developers looking to learn about new developments in the framework. I really want to thank you for the content you provide, especially on Spring AI and GraphQL. I thoroughly enjoy watching your videos.

I was wondering if you have any plans to cover topics like RSocket, Spring Reactive, and monitoring in Spring 3.
Thanks

[ferbernardino]

The best explanation I've found. Thanks!

[debashishbhattacharjee]

Simple. To the point and precise. Highly appreciate your work.

Would be great to create a video with mutations where objects are created/updated/deleted and also maybe how to send/receive headers and do AuthN/Z

[kmekky]

Another great video. I love how active you've been lately. Keep it up. 👏

[SerhiiPylypenko-ow]

Very quick, informative, and straightforward explanation. Thanks a lot!

Why is it a Mono for something that is many things? ie. List<Country>

It would be more beneficial to demonstrate how microservices would talk to each other with GraphQL with different types of data structures.

Hi, Great video. Can we have one demonstrating on how we handle errors?

[shadowslayerhero]

Nice Vid!, would be great if you could also show how we could use the graphql client with authentication :D

[ajisegirisunday]

Great stuff... How do we retrieve the headers as part of the response body??

[raedgeorge]

thanks for this video. can you show us how to mutate using graphql client. i tried on my own, the mutate works but i can't figure out a way to
get the response as a Java Model Class. i was able to use Map to get key value pairs to extract the inserted element id and query the database
again to get the record from the database.
thanks in advance

[Muescha]

can you add the info how we can get the autocompletion in the `string document` graphql string

[sunilkumarkalagata]

This is more helpful, Could you please findbyId call with WebClient

[muralikrishna]

Can you please share video for implementing custom directives in graphql using spring boot

[jeres]

Can you show a video of using graphqlclient with variables?

[AngelicaV]

awesome! do you know how to make an unit test of this? I mean for the service class

[bogdanjovanovic]

Why GraphQL client is not mapping Java records/pojo classes automatically in GraphQL query string?

[dominicvinod]

hi can you share an example with resttemplate please if possible. I know its going to be deprecated but will help dev team with older version
