GraphQL support in Spring

This project demonstrates 3 different Spring implementations of GraphQL protocol: Netflix DGS, Java Kickstart and Spring for GraphQL. Every implementation is in its own module and they all share the same GraphQL schema and fetch data using common class. Security configuration is also the same. Every module is covered with integration tests.

It also has two Apollo React clients that uses different WebSocket implementations.

Modules

• graphql-core library with common code and resources
• graphql-dgs Netflix DGS module
• graphql-kickstart Java Kickstart module - DEPRECATED
• graphql-spring Spring for GraphQL module

Security

• Every module uses form login: admin/admin.
• In order to disable security start components with no-security spring profile.
• WebSocket authentication can be done in two ways:
  • using session cookies when client is embedded in a page
  • using authToken in connection payload that simulates Bearer token authentication. This is demonstrated in Apollo React clients. Note that DGS implementation doesn't support it.

Misc

• Every component starts on 8080 port by default.
• Every component exposes Apollo React client on http://localhost:8080/apollo/index.html. Note that DGS and Spring implementations shares the same Apollo client in graphql-core module. That client uses new WebSocket protocol. Kickstart has its own Apollo client that uses deprecated protocol.
