Thanks..

Thanks for sharing the sample code here.. If you could correct the below method by adding the prefix TypeRuntimeWiring, it will help starters like me.

private RuntimeWiring buildWiring() {
return RuntimeWiring.newRuntimeWiring()
.type(TypeRuntimeWiring.newTypeWiring("Query")
.dataFetcher("bookById", graphQLDataFetchers.getBookByIdDataFetcher()))
.type(TypeRuntimeWiring.newTypeWiring("Book")
.dataFetcher("author", graphQLDataFetchers.getAuthorDataFetcher()))
.build();
}

Closing this issue as the tutorial has been rewritten with Spring for GraphQL, which automatically wires up datafetchers
