This repository contains a simple implementation of a GraphQL server using Java. It demonstrates how to set up a basic GraphQL API to handle queries, mutations, and schema definitions.

Services

This demo consists of the following service:

• Products Service: Handles product information

Queries

    query {
        getProduct(id: null) {
            price
            name
            id
        }
    }
  

Mutations

• createProduct

    mutation {
        createProduct(productDTO: { id: null, name: null, price: null })
    }
  

• deleteProduct

        deleteProduct(id: null)
    }

Accessing the Services

The service's endpoints can be accessed through http://localhost:8080/graphql.

Testing

You can test the service using tools like Postman or by sending raw requests via curl or any HTTP client library.
