Spring Boot with GraphQL Query Example

Spring Boot with GraphQL Query Example

Update: Upgraded to Java 11 and Graph QL to 5+ version dependency

Book Store

• /rest/books is the REST resource which can fetch Books information
• DataFetchers are Interfaces for RuntimeWiring of GraphQL with JpaRepository

Sample GraphQL Scalar Queries

• Accessible under http://localhost:8091/rest/books
• Usage for allBooks

{
   allBooks {
     isn
     title
     authors
     publisher
   }
 }

• Usage for book

  {
   book(id: "123") {
     title
     authors
     publisher
   }

• Combination of both allBooks and book

{
   allBooks {
     title
     authors
   }
   book(id: "124") {
     title
     authors
     publisher
   }
 }

using spring boot as client

Can you pls help, how we can use graphql API in the spring boot app?

treating spring boot as client

Graphql+springboot

GraphiQL

How can I use GraphiQL to query?
I can query using Postman, but GraphiQL show and error:

{
  "errors": [
    {
      "message": "Invalid Syntax",
      "locations": [
        {
          "line": 1,
          "column": 1
        }
      ],
      "errorType": "InvalidSyntax"
    }
  ],
  "data": null,
  "extensions": null
}

And in the app console I can see the following error:
graphql.GraphQL : Executing request. operation name: null. Request: {"query":"{\n\n\n\tbook (id: \"111\"){\n\t\tisn\n\t\ttitle\n\t\tauthors\n\t}\n\n\n}","variables":null,"operationName":null}

It seems that GraphiQL add "query" at the top of the request.

InvalidSyntax error on executing this project

While trying to execute the project using below query

{
book(id: "123") {
title
authors
publisher
}
}

I am getting below error.

{
"data": null,
"errors": [
{
"message": "Invalid Syntax",
"locations": [
{
"line": 1,
"column": 1,
"sourceName": null
}
],
"errorType": "InvalidSyntax",
"path": null,
"extensions": null
}
],
"dataPresent": false,
"extensions": null
}

On server side I am getting below error

2021-05-12 18:11:10.346 WARN 16964 --- [o-auto-1-exec-5] graphql.GraphQL : Query failed to parse : '{"operationName":null,"variables":{},"query":"{\n book(id: "123") {\n title\n authors\n publisher\n }\n}\n"}'

Please help in understanding the root cause of this problem and how to fix the same.

how to pass List data type to the graphql

I watch the video on youtube and I have a question of pass special data type. for example, if there are two entities class inside the model, one is for Book like yours and another one is author. In the Book entity class, private List <author> authors. And in the author class, it contains: authorName, authorAge.... In this case, how should pass authors list into the graphql script?
