问题
Currently we are using
<dependency>
<groupId>com.graphql-java-kickstart</groupId>
<artifactId>graphql-spring-boot-starter</artifactId>
<version>${graphql-spring-starter.version}</version>
</dependency>
With this, we are exposing our graphql API using /graphql endpoint. I want to have multiple endpoints like this, /graphql1 and /graphql2 so that I can define different response formats based on the endpoints. what is the best way to do it? Any inputs is highly appreciated.
回答1:
It just boils down to create a GraphQLHttpServlet
and configure its context path. Under the cover , it uses auto-configuration GraphQLWebAutoConfiguration
to define a GraphQLHttpServlet
as a bean, and configure the context path to be /graphql
.
That means you can reference how GraphQLWebAutoConfiguration
does and create another GraphQLHttpServlet
instance that registered to other context path.
The main point is that to register a Servlet
in spring boot , you can simply create a ServletRegistrationBean
that wraps the HttpServlet
which you want to create .See docs for more details.
A simple example is :
@Bean
public ServletRegistrationBean<AbstractGraphQLHttpServlet> fooGraphQLServlet() {
//Create and configure the GraphQL Schema.
GraphQLSchema schema = xxxxxxx;
GraphQLHttpServlet graphQLHttpServlet = GraphQLHttpServlet.with(schema);
ServletRegistrationBean<AbstractGraphQLHttpServlet> registration = new ServletRegistrationBean<>(
graphQLHttpServlet, "/graphql2/*");
registration.setName("Another GraphQL Endpoint");
return registration;
}
