Java 阻塞的vertx线程
我必须学会使用以下工具开发微服务：Java 阻塞的vertx线程,java,mongodb,docker,maven-3,vert.x,Java,Mongodb,Docker,Maven 3,Vert.x,我必须学会使用以下工具开发微服务： 爪哇8 Vertx 3.9 Maven 3.6 Docker上的MongoDB 19.03.1 作为一个IDE，我使用Intellij 我正在研究的代码是： import io.vertx.core.AbstractVerticle; import io.vertx.core.Future; import io.vertx.core.Promise; import io.vertx.core.Vertx; import io.vertx.core.http
