在Java/Spring中将GraphQL响应映射到类

@GraphQLName("Person")
public class Person {
    @GraphQLField
    private String name;

    @GraphQLField
    private int age;

    // Getters and setters
}

@GraphQLName("Query")
public class Query {
    @GraphQLField
    public Person getPersonById(int id) {
        // Logic to fetch the person from database or any other source
        // Return the person object
    }
}

GraphQLSchema schema = GraphQLSchema.newSchema()
    .query(GraphQLObjectType.newObject()
        .name("Query")
        .field(field -> field
            .name("person")
            .type(GraphQLObjectType.newObject()
                .name("Person")
                .field(field -> field
                    .name("name")
                    .type(Scalars.GraphQLString))
                .field(field -> field
                    .name("age")
                    .type(Scalars.GraphQLInt)))
            .dataFetcher(environment -> {
                int id = environment.getArgument("id");
                // Fetch the person by id
                return new Person("John Doe", 30);
            })))
    .build();

GraphQL graphQL = GraphQL.newGraphQL(schema).build();

ExecutionResult result = graphQL.execute("{ person(id: 1) { name, age } }");
Person person = result.getData().get("person", Person.class);
