如果你的应用程序没有使用 Spring Boot，你需要负责设置相关的 Spring for GraphQL 组件。假设你的应用程序已经配置了 Spring MVC 控制器，那么最低限度的设置将需要几个 bean。

import java.util.List;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.graphql.ExecutionGraphQlService;
import org.springframework.graphql.data.method.annotation.support.AnnotatedControllerConfigurer;
import org.springframework.graphql.execution.ConnectionTypeDefinitionConfigurer;
import org.springframework.graphql.execution.DefaultBatchLoaderRegistry;
import org.springframework.graphql.execution.DefaultExecutionGraphQlService;
import org.springframework.graphql.execution.GraphQlSource;
import org.springframework.graphql.server.WebGraphQlHandler;
import org.springframework.graphql.server.webmvc.GraphQlHttpHandler;
import org.springframework.graphql.server.webmvc.GraphQlRequestPredicates;
import org.springframework.graphql.server.webmvc.GraphiQlHandler;
import org.springframework.web.servlet.function.RequestPredicate;
import org.springframework.web.servlet.function.RouterFunction;
import org.springframework.web.servlet.function.RouterFunctions;
import org.springframework.web.servlet.function.ServerResponse;

@Configuration(proxyBeanMethods = false)
public class GraphQlConfiguration {

	@Bean 1
	public AnnotatedControllerConfigurer controllerConfigurer() {
		return new AnnotatedControllerConfigurer();
	}

	@Bean 2
	public ExecutionGraphQlService executionGraphQlService(AnnotatedControllerConfigurer controllerConfigurer) {
		GraphQlSource graphQlSource = GraphQlSource.schemaResourceBuilder() 3
				.schemaResources(new ClassPathResource("graphql/schema.graphqls"))
				.configureTypeDefinitions(new ConnectionTypeDefinitionConfigurer())
				.configureRuntimeWiring(controllerConfigurer)
				.exceptionResolvers(List.of(controllerConfigurer.getExceptionResolver()))
				.build();
		DefaultBatchLoaderRegistry batchLoaderRegistry = new DefaultBatchLoaderRegistry();
		DefaultExecutionGraphQlService service = new DefaultExecutionGraphQlService(graphQlSource);
		service.addDataLoaderRegistrar(batchLoaderRegistry);
		return service;
	}

	@Bean 4
	public RouterFunction<ServerResponse> graphQlRouterFunction(ExecutionGraphQlService graphQlService) {
		WebGraphQlHandler webGraphQlHandler = WebGraphQlHandler.builder(graphQlService).build();
		GraphQlHttpHandler graphQlHttpHandler = new GraphQlHttpHandler(webGraphQlHandler);
		RequestPredicate graphQlPredicate = GraphQlRequestPredicates.graphQlHttp("/graphql");
		GraphiQlHandler graphiQlHandler = new GraphiQlHandler("/graphql", "");
		return RouterFunctions.route() 5
				.route(graphQlPredicate, graphQlHttpHandler::handleRequest)
				.GET("/graphiql", graphiQlHandler::handleRequest)
				.build();
	}
}

• AnnotatedControllerConfigurer bean 负责检测 GraphQL @Controller 处理器。

• ExecutionGraphQlService 以与传输协议无关的方式处理 GraphQL 请求。

• GraphQlSource 构建器是主要的配置点。探索其 API 以获取更多选项。

• RouterFunction 将 GraphQL 路由作为函数式端点公开。

• 然后，您可以在不同的路由上公开各种传输协议（WebSocket、SSE、HTTP）。

Spring for GraphQL 提供了许多其他选项以及与 Spring 项目的集成。要了解更多信息，您可以探索 Spring Boot 自动配置。
