Hi there. I have a GraphQL service implemented using spring boot (spring-boot-starter-graphql). I’m looking to use it as a subgraph with Apollo Federation v2. The documentation here, [https://www.apollographql.com/docs/federation/building-supergraphs/supported-subgraphs/](https://www.apollographql.com/docs/federation/building-supergraphs/supported-subgraphs/), indicates that critical support for the “@link” directive is missing. However, it appears that graphql-java-support does include it - [federation-jvm/graphql-java-support/src/main/resources/definitions\_fed2\_0.graphqls at main · apollographql/federation-jvm · GitHub](https://github.com/apollographql/federation-jvm/blob/master/graphql-java-support/src/main/resources/definitions_fed2_0.graphqls#L40). Is the documentation accurate? Am I missing something? Also, if @link is not yet available. Will this prevent me from going forward using spring-boot? Thanks, Mike ---

Hello 👋 `graphql-java-kickstart` is using `graphql-java-tools` to load the schema which currently does not support schema directives (see [Support schema directives · Issue #717 · graphql-java-kickstart/graphql-java-tools · GitHub](https://github.com/graphql-java-kickstart/graphql-java-tools/issues/717)). Without the presence of `@link` directive, router/gateway logic will fallback to V1 behavior. You can definitely use Spring Boot - you can continue using Kickstart (but will be using Fed v1) or you can use some other Spring Boot implementations (e.g. [Netflix DGS Framework](https://netflix.github.io/dgs/), Official [Spring GraphQL](https://docs.spring.io/spring-graphql/docs/current/reference/html/) project or ExpediaGroup [GraphQL Kotlin](https://opensource.expediagroup.com/graphql-kotlin/docs/) (if you don’t mind Kotlin and prefer code-first solution)). Thanks, Derek ---

Oh, I got it. I think I was confusing `graphql-java-kickstart` with `spring-boot-starter-graphql` (Official [Spring GraphQL](https://docs.spring.io/spring-graphql/docs/current/reference/html/) project). Since I’m using `spring-boot-starter-graphql`, not `graphql-java-kickstart`, I should be good for Fed v2. Thanks! P.S. I guess I should have been looking at the compatibility for Federation JVM, not GraphQL Java Kickstart. ---

Hey Michael, I’m trying to deal with the same approach. Do you mind sharing a git repo to point out your code with Spring boot + federation. I’m trying to use spring boot 2.7.x with spring-boot-starter-graphql, but the application is failing to start whenever i use a directive like @key ---

@dkuc thanks for the pointer, I tried to replicate the same with the below version and my application is failing to start. Any thoughts?

Without seeing the code base it is hard to say what is missing in your setup but most likely you didn’t [transform the schema](https://github.com/apollographql/federation-jvm-spring-example/blob/main/reviews-subgraph/src/main/java/com/example/reviews/GraphQLConfiguration.java). ---

Spring GraphQL requires explicit schema transformation to enable federation → see example code linked above. ---

Thanks @dkuc it worked after making some changes to the dependency conflicts. Do we have a provision to see query plan for the subgraphs (spring boot way)? ---

Unsure what you mean by “spring boot way” → Apollo Studio can be used with any GraphQL server. ---

Thank you that makes sense. Do we have any provisioning enabled to implement Apollo gateway layer using Java Spring or we need to go with JavaScript way. ---

We don’t have any Java support for the gateway. We support Javascript (called gateway) and Rust (called router to easily distinguish it from JS) implementations. ---

Hi @dkuc I hope you are doing good. I’m writing this to you as I’m struck with Apollo Client testing at React. We usually create a express server to run as bff mock for the UI to load mock data to develop UI on top of it locally. One of our UIs use Apollo client to invoke the backend ‘/graphql’ endpoint served on POST for both queries and mutation. While trying to mock the API behavior from the UI side, we are unable to serve the request based on the body passed to the graphql endpoint. I tried making use of MSW and it is not even intercepting the graphql endpoint calls invoked by the Apollo client locally. Also, when i try to mock via rest by matching the endpoint, I see that the request is served for the /graphql endpoint with the mock data, but we couldnt capture the body of the request. The idea here is to conditionally serve a response to the /graphql endpoint based on the request body i.e. Query or Mutation. Any suggestions on how to achieve this? Note: Our GraphQL back end is based on Spring Boot and it only exposes the endpoint as POST. Sample Express Code: ```auto /* eslint-disable import/no-extraneous-dependencies */ const express = require('express') const { graphql, rest } = require('msw') const { createMiddleware } = require('@mswjs/http-middleware') const { verify } = require('njwt') const fs = require('fs') const config = require('../config') // import { readFileSync } from 'fs' // import { bff, bffMock } from '../config' const secret = 'shhhhhhhh' const jwtRegEx = /^[bB]earer\s+([-\w-]+.[-\w]+.[-\w]+)$/ const graphApi = graphql.link('/graphql') const query = ` query GetTasksByAssignee($assignee: String!) { tasksByAssignee(assignee: $assignee) { name creationDate dueDate } } ` const getJwtFromAuthHeader = req => { const authorizationHeader = req.header('Authorization') const match = jwtRegEx.exec(authorizationHeader || '') return match && (match[1] || '') } const buildMswApp = ({ mockFilename, secure }) => { const app = express() // Register json server's middleware app.use( createMiddleware( rest.post('/graphql', (req, res, ctx) => { console.log(req) return res( ctx.json({ data: { tasksByAssignee: [ { id: 209757, name: 'CKARTH 1 login metadata', creationDate: '2011-05-23T04:22:55.000+00:00', dueDate: '2011-05-25T04:22:55.000+00:00' } ] } }) ) }), graphql.operation(async (req, res, ctx) => { const { query } = await req.json() console.log(query) return res( ctx.data({ tasksByAssignee: [ { id: 209757, name: 'CKARTH 1 login metadata', creationDate: '2011-05-23T04:22:55.000+00:00', dueDate: '2011-05-25T04:22:55.000+00:00' } ] }) ) }), graphApi.query('GetTasksByAssignee', (req, res, ctx) => { const { assignee } = req.variables console.log('aa gya') return res( ctx.data({ tasksByAssignee: [ { id: 209757, name: 'CKARTH 1 login metadata', creationDate: '2011-05-23T04:22:55.000+00:00', dueDate: '2011-05-25T04:22:55.000+00:00' } ] }) ) }), graphApi.mutation('completeTask', (req, res, ctx) => { const { assignee } = req.variables console.log('aa gya') return res( ctx.data({ tasksByAssignee: [ { id: 209757, name: 'CKARTH 1 login metadata', creationDate: '2011-05-23T04:22:55.000+00:00', dueDate: '2011-05-25T04:22:55.000+00:00' } ] }) ) }) ) ) // Configure response with correct API version app.use((req, res, next) => { const jwt = getJwtFromAuthHeader(req) if (secure) { verify(jwt, secret, err => { if (err) { res.status(401) res.send('Unauthorized') } else { console.log('heelo') res.header('Content-Type', config.bff.api.contentType) } next() }) } else { res.header('Content-Type', config.bff.api.contentType) next() } }) // Register any custom endpoints here before the jsonServer router is registered. // You can modify the 'mock.json' file and the changes will be reflected in the mock server. // app.use('/custom', customMiddleware()) // app.post('/graphql', (req, res) => { // console.log(req.query.query) // const mockData = JSON.parse(readFileSync(mockFilename, 'utf8')) // res.status(200) // res.send(mockData.tasks) // }) // Register router // app.use(bffMock.api.path, router) return app } module.exports = buildMswApp ``` In the above code, only the rest handler is intercepting the graphql endpoint, but cannot capture the body in the res variable. Whereas none of the graphql handlers intercept the graphql invocation and always result in 404. ---

The sample shown below only shows how to use “@key” annotation and not others.
