Using existing schema for requests

[wiedehoeft]

The Graphql-java tools provide the possibility to execute queries on server-side: https://www.graphql-java.com/documentation/v16/execution/

But it is unclear how to use this with graphql-java-kickstart. The existing schema file is parsed and the only need for implementations are the resolver with a DataFetchingEnvironment.

Exists part that can be reused for the upper example to use the existing, parsed schema definition for new custom queries?

We have tried it this way

    File schemaFile1 = new File(getClass().getClassLoader().getResource("mainAccount-schema.graphqls").getFile());
    final TypeDefinitionRegistry typeDefinitionRegistry = new SchemaParser().parse(schemaFile1);

    final GraphQLSchema schema = new SchemaGenerator().makeExecutableSchema(typeDefinitionRegistry, RuntimeWiring.newRuntimeWiring().build());
    GraphQL graphQL = GraphQL.newGraphQL(schema)
      .build();

    ExecutionInput executionInput = ExecutionInput.newExecutionInput().query("[...]")
      .build();

    ExecutionResult executionResult = graphQL.execute(executionInput);
    Object data = executionResult.getData();
    List<GraphQLError> errors = executionResult.getErrors();

But the result is always empty {data={getMainAccount=null}}, after execution with a SpringBootIntegrationTest. This does not surprise, because the classes which implement methods with dataFetchingEnvironment are not called.

Thank you,
the missing link was the injection :)
Maybe it would be helpful to add this hint in the documentation, that the configured objects are injectable.
