Schema

  • DataFetcher:

    • query: Provides the data for a filed.
    • mutation: query + changes something, as POST(or PUT)

    Every field definition has a DataFetcher. when not configured, PropertyDataFetcher is used. It fetches data from Map & Java Beans.

  • TypeResolver: helps graphql-java to decide which type a concrete value belongs to. It is needed for Interface and Union.
