Vertx 虚拟线程孵化

https://github.com/vert-x3/vertx-virtual-threads-incubator/blob/main/examples/src/main/java/examples/HttpClientExample.java

public class HttpClientExample { public static void main(String[] args) { Vertx vertx = Vertx.vertx(); HttpServer server = vertx.createHttpServer(); server.requestHandler(request -> { request.response().end("Hello World"); }); Future<HttpServer> fut = server.listen(8080, "localhost"); Async async = new Async(vertx); async.run(v -> { // Run on a Vert.x a virtual thread // Make sure server is started await(fut); // Make a simple HTTP request HttpClient client = vertx.createHttpClient(); HttpClientRequest req = await(client.request(HttpMethod.GET, 8080, "localhost", "/")); HttpClientResponse resp = await(req.send()); int status = resp.statusCode(); Buffer body = await(resp.body()); System.out.println("Got response '" + body + "'"); }); } } 

这里的 async 和 await 多此一举，只是把异步的 future 转成同步。感觉 Spring Webflux 和 Vertx 这类响应式的 Web 框架已经没必要了，使用基于虚拟线程的 Spring MVC 足矣，当然只是感觉没有实测过。

我也找了很久都没有关于 Servlet 和 JDBC 利用虚拟线程的文章
