Description copied from interface: QueryDataFetchersDelegate

This method loads the data for Query.hello.
For optimization, this method returns a CompletableFuture. This allows to use graphql-java java-dataloader to highly optimize the number of requests to the server.
The principle is this one: The data loader collects all the data to load, avoid to load several times the same data, and allows parallel execution of the queries, if multiple queries are to be run.
You can implements this method like this:

Specified by:

hello in interface QueryDataFetchersDelegate

Parameters:

dataFetchingEnvironment - The GraphQL DataFetchingEnvironment. It gives you access to the full GraphQL context for this DataFetcher

name - The input parameter sent in the query by the GraphQL consumer
