Features

Graphql-java 11.0

Upgraded graphql-java to 11.0. See their release notes fur further details.

Type Definition Factory

Added the type definition factory to make it possible to dynamically add type definitions after the SDL has been parsed. This is used to automatically generate Relay connection type definitions. See https://www.graphql-java-kickstart.com/tools/type-definition-factory/ for more details.

Automatic generation of Relay Type Definitions

Relay Type Definitions can now be automatically generated using the @connection directive. See https://www.graphql-java-kickstart.com/tools/relay/ for more details and basic usage.

Directives

Support for directives has been included now. See https://www.graphql-java-kickstart.com/tools/directives/ for more details and basic usage.

Other features

#104 Coroutine support

Support Java 11

Upgraded commons-lang3 to version 3.8.1 to support Java 11.

Support for PropertyDataFetcher behavior

When using graphql-java alone and taking the approach of writing DataFetchers, the framework will allow you to return a Map object that contains the property names and values for the corresponding GraphQL type and the framework will then map this to the appropriate GraphQL type using the PropertyDataFetcher (as described in https://graphql-java.readthedocs.io/en/latest/schema.html under DataFetcher and TypeResolver).

This same behavior was not supported when using graphql-java-tools with the GraphQLResolver approach up until now.

Here is an example:

public class Book {

    private int id;
    private String name;
    private int authorId;

    // constructor and getters/setters ...
}

public class BookResolver implements GraphQLResolver<Book> {

    public Map author(Book book) {

        return Collections.unmodifiableMap(new HashMap<String, Object>() {
            {
                put("id", "1");
                put("name", "smith");
            }
        });
    }
}

The GraphQL schema file is:

type Query {
    books: [Book!]
}

type Book {
    id: Int!
    name: String!
    author: Author!
}

type Author {
    id: Int!
    name: String!
}

Option for disabling introspection query

Graphql-java provides a feature to disable the introspection query: https://graphql-java.readthedocs.io/en/latest/execution.html?highlight=introspection#limiting-field-visibility. They do warn that it puts your server in contravention of the GraphQL specification and expectations of most clients so use this with caution.

Updated Maven coordinates in Central

The artifacts are available in Maven Central starting with this version.

Changed organization

Starting with this release the project has moved out of the graphql-java organization into graphql-java-kickstart. This because they are in fact separate projects where maintainers of the one actually weren't involved in maintenance of the other. This resulted in it becoming quite unclear what is actually graphql-java and what was a library on top. This confusion was clearly visible in the Gitter channel as well. That's why we split the projects and the Gitter channels.

Maven

<dependency>
    <groupId>com.graphql-java-kickstart</groupId>
    <artifactId>graphql-java-tools</artifactId>
    <version>5.3.1</version>
</dependency>

Gradle

compile 'com.graphql-java-kickstart:graphql-java-tools:5.3.1'

Support for generic types

Support for generics has been improved. This makes it easier to implement pagination for example. Instead of having to create concrete classes one could now do:

import graphql.relay.Connection
import graphql.relay.SimpleListConnection

@Component
class QueryResolver implements GraphQLQueryResolver {

    private UserService userService;

    Connection<User> users(int first, String after, DataFetchingEnvironment env) {
        return new SimpleListConnection<User>(userService.filter(page, size)).get(env);
    }
}

Updated graphql-java dependency

Updated to the latest 10.0 version of graphql-java.
