Simple and So useful. I will rate it the best GraphQL video. Thanks a ton.

Thank you so much for all the hard work you put into the video. Truly appreciate it. Thank you again. Looking forward for GraphQl with spring security.

Thank you so much for this video. I was able to create my 1st ever graphql api.

Thanks for this video Dan. I had 2 requests: Could you show how to correctly do BatchMapping and how to correctly build your own GraphQl Protocol handler other than the built in Http, WebSocket and RSocket handlers.

Hi Dan, again thanks for that session, it was easy to follow and I could see the requests being sent and received with the web client on my local host. As a GraphQL noob Iand as an old Spring grunt still wonder why would I expose the controllers to a GraphQL client. Why not using REST for the client calls ? What GraphQL adds that would be helpful to the client ? Why a client would want to send GraphQL requests instead of REST ones ? And in fact, can a client, that is known to send REST requests, also send GraphQL requests at all ? Thanks for the awesome effort of yours ! I shall continue in the series and hopefully start playing with AI on your sessions. Cheers, Stephane, France

Hello @DanVega, thanks for the tutorial. A question, how can we change the output field name from id to say coffe_id without changing the member variable name in java code. What is the solution if I want to customize the output field name and do not want it to be equal to java member varaible name.

Hi Dan - can you show a single example to do crud operation using MySQL db

What if your input parameter of the mutation is a list of input objects?

f.e.

public coffees){ // do something here}

How to pass a full request body to GraphQL?

Hi Dan, Im trying to create a graphQL Crud API with springboot and my problem is that i dont know how to pass an object as an argument of a mutation. I tryed to use an input object but i need de id of the object that is related with this one.
type Endpoint {
id: ID!
name: String!
doc: String!
typeOP: String!
nameOp: String!
aplication: Aplication!
}
Is a ManyToOne relationship
How can i create a Mutation (createEndpoint) passing only a endpoint that is supposed to be a Object getted from the frontEnd?¿
