Spring for GraphQL

1. Setup project. start.spring.io

   • Gradle-Kotlin
   • Kotlin
   • Java 17
   • Spring Web
   • Spring GraphQL

2. Add GraphQL Schema CodeGen Netflix DGS Codegen

        plugins {
            id("com.netflix.dgs.codegen") version "6.0.2"
        }
   
        tasks.generateJava {
            language = "kotlin"
            schemaPaths = mutableListOf("${projectDir}/src/main/resources/graphql")
            packageName = "com.cuizhanming.template.kotlin.codegen"
        }
   

3. Add GraphQL Schema, under schemaPath configured as above step /src/main/resources/graphql

        type TaxCredit {
            id: ID!
            name: String!
            year: Int!
            amount: Float!
            type: String!
            issuedAt: String!
            createdAt: String!
            updatedAt: String!
        }
   
        type Query {
            availableCredits(year: String): [TaxCredit]
        }
