https://graphql.org/[GraphQL] support for Spring applications with https://github.com/graphql-java/graphql-java[GraphQL Java].
== Getting started
This project is tested against Spring Boot 2.4+.
You can start by creating a project on https://start.spring.io and select the `spring-boot-starter-web` or `spring-boot-starter-webflux` starter,
depending on the type of web application you'd like to build. Once the project is generated, you can manually add the
`org.springframework.experimental:graphql-spring-boot-starter` dependency.
`build.gradle` snippet:
[source,groovy,indent=0,subs="verbatim,quotes"]
----
dependencies {
implementation 'org.springframework.experimental:graphql-spring-boot-starter:1.0.0-SNAPSHOT'
// Spring Web MVC starter
implementation 'org.springframework.boot:spring-boot-starter-web'
// OR Spring WebFlux starter
implementation 'org.springframework.boot:spring-boot-starter-webflux'
}
repositories {
mavenCentral()
// don't forget to add spring milestone or snapshot repositories
maven { url 'https://repo.spring.io/milestone' }
maven { url 'https://repo.spring.io/snapshot' }
}
----
`pom.xml` snippet:
[source,xml,indent=0,subs="verbatim,quotes"]
----
<dependencies>
<dependency>
<groupId>org.springframework.experimental</groupId>
<artifactId>graphql-spring-boot-starter</artifactId>
<version>1.0.0-SNAPSHOT</version>
</dependency>
<!-- Spring Web MVC starter -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- OR Spring WebFlux starter -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
<!-- ... -->
</dependencies>
<!-- Don't forget to add spring milestone or snapshot repositories -->
<repositories>
<repository>
<id>spring-milestones</id>
<name>Spring Milestones</name>
<url>https://repo.spring.io/milestone</url>
</repository>
<repository>
<id>spring-snapshots</id>
<name>Spring Snapshots</name>
<url>https://repo.spring.io/snapshot</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
</repositories>
----
You can now add a GraphQL schema in `src/main/resources/graphql/schema.graphqls` such as:
[source,javascript,indent=0,subs="verbatim,quotes"]
----
type Query {
people: [Person]!
}
type Person {
id: ID!
name: String!
}
----
Then you should configure the data fetching process using a `RuntimeWiringCustomizer` and custom components like
Spring Data repositories, `WebClient` instances for Web APIs, a `@Service` bean, etc.
[source,java,indent=0,subs="verbatim,quotes"]
----
@Component
public class PersonDataWiring implements RuntimeWiringCustomizer {
private final PersonService personService;
public PersonDataWiring(PersonService personService) {
this.personService = personService;
}
@Override
public void customize(RuntimeWiring.Builder builder) {
builder.type("Query", typeWiring -> typeWiring
.dataFetcher("people", env -> this.personService.findAll()));
}
}
----
You can now start your application!
A GraphiQL web interface is available at `http://localhost:8080/graphql` and you can use GraphQL clients
to POST queries at the same location.
== Features
=== Core configuration
The Spring GraphQL project offers a few configuration properties to customize your application:
[source,properties,indent=0,subs="verbatim,quotes"]
----
# web path to the graphql endpoint
spring.graphql.path=/graphql
# locations of the graphql '*.graphqls' schema files
spring.graphql.schema.locations=classpath:graphql/
# schema printer endpoint configuration
# endpoint path is concatenated with the main path, so "/graphql/schema" by default
spring.graphql.schema.printer.enabled=false
spring.graphql.schema.printer.path=/schema
# GraphiQL UI configuration
spring.graphql.graphiql.enabled=true
spring.graphql.graphiql.path=/graphiql
# whether micrometer metrics should be collected for graphql queries
management.metrics.graphql.autotime.enabled=true
----
You can contribute `RuntimeWiringCustomizer` beans to the context in order to configure the runtime wiring of your GraphQL application.
=== WebSocket support
This project also supports WebSocket as a transport for GraphQL requests - you can use it to build [`Subscription` queries](http://spec.graphql.org/draft/#sec-Subscription).
This use case is powered by Reactor `Flux`, check out the `samples/webflux-websocket` sample application for more.
To enable this support, you need to configure the `spring.graphql.websocket.path` property in your application
and have the required dependencies on classpath. In the case of a Servlet application, adding the `spring-boot-starter-websocket` should be enough.
WebSocket support comes with dedicated properties:
[source,properties,indent=0,subs="verbatim,quotes"]
----
# Path of the GraphQL WebSocket subscription endpoint.
spring.graphql.websocket.path=/graphql/websocket
# Time within which the initial {@code CONNECTION_INIT} type message must be received.
spring.graphql.websocket.connection-init-timeout=60s
----
=== Extension points
You can contribute [`WebInterceptor` beans](https://github.com/spring-projects-experimental/spring-graphql/blob/master/spring-graphql/src/main/java/org/springframework/graphql/WebInterceptor.java)
to the application context, so as to customize the `ExecutionInput` or the `ExecutionResult` of the query.
A custom `WebInterceptor` can, for example, change the HTTP request/response headers.
=== Testing support
When the `spring-boot-starter-test` dependency is on the classpath, Spring GraphQL provides a testing infrastructure for your application.
Spring Boot allows you to test your web application with [with a mock environment](https://docs.spring.io/spring-boot/docs/current/reference/html/features.html#features.testing.spring-boot-applications.with-mock-environment)
or [with a running server](https://docs.spring.io/spring-boot/docs/current/reference/html/features.html#features.testing.spring-boot-applications.with-running-server).
In both cases, adding the `@AutoConfigureGraphQlTester` annotation on your test class will contribute a `GraphQlTester` bean you can inject and use in your tests:
[source,java,indent=0,subs="verbatim,quotes"]
----
@SpringBootTest
@AutoConfigureMockMvc
@AutoConfigureGraphQlTester
public class MockMvcGraphQlTests {
@Autowired
private GraphQlTester graphQlTester;
@Test
void jsonPath() {
String query = "{" +
" project(slug:\"spring-framework\") {" +
" releases {" +
" version" +
" }" +
" }" +
"}";
this.graphQlTester.query(query)
.execute()
.path("project.releases[*].version")
.entityList(String.class)
.hasSizeGreaterThan(1);
}
}
----
=== Metrics
If the `spring-boot-starter-actuator` dependency is on the classpath, metrics will be collected for GraphQL requests.
You can see those metrics by exposing the metrics endpoint with `application.properties`:
[source,properties,indent=0,subs="verbatim,quotes"]
----
management.endpoints.web.exposure.include=health,metrics,info
----
==== GraphQL Request (timer)
A Request metric timer is available at `/actuator/metrics/graphql.request`.
[cols="1,2,2"]
|===
|Tag | Description| Sample values
|outcome
|Request outcome
|"SUCCESS", "ERROR"
|===
==== GraphQL Data Fetcher (timer)
A Data Fetcher metric timer is available at `/actuator/metrics/graphql.datafetcher`.
[cols="1,2,2"]
|===
|Tag | Description| Sample values
|path
|data fetcher path
|"Query.project"
|outcome
|data fetching outcome
|"SUCCESS", "ERROR"
|===
==== GraphQL Error (counter)
A counter metric counter is available at `/actuator/metrics/graphql.error`.
[cols="1,2,2"]
|===
|Tag | Description| Sample values
|errorType
|error type
|"DataFetchingException"
|errorPath
|error JSON Path
|"$.project"
|===
== Sample applications
