Sample GraphQL server implemented with graphql-java and Spring Boot

graphql-java-spring-boot-example

Sample app for my tutorial Building a GraphQL Server with Spring Boot.

Updated by @Ansonator to recent versions of Spring Boot and GraphQL Java.

The tutorial branch contains the original demo app.

You'll need Java 11 or 17.

Clone this repo and execute mvnw spring-boot:run. Or inside an IDE, execute the class com.example.DemoGraphQL.DemoGraphQlApplication.

To access the database, you can go to http://localhost:8080/h2-console/login.jsp and enter the following information:

• JDBC URL: jdbc:h2:mem:testdb
• User Name: sa
• Password:

Or go to http://localhost:8080/graphiql to start executing queries. For example:

{
  findAllBooks {
    id
    isbn
    title
    pageCount
    author {
      firstName
      lastName
    }
  }
}

Or:

mutation {
  newBook(
    title: "Java: The Complete Reference, Tenth Edition", 
    isbn: "1259589331", 
    author: 1) {
      id title
  }
}
