问题 consider the following json { "sub1":{ "name":"Name-sub1", "sub11":{ "name":"Name-sub11", "sub111":{ "name":"Name-sub111", ... }, .. }, ... }, ... } I now want to fetch the inner name Element (Name-sub111) in java (it's a io.vertx.core.json.JsonObject) object.getJsonObject("sub1").getJsonObject("sub11").getJsonObject("sub111").getString("name") But I'm not sure if sub1 or sub11 or sub111 even exist - so I always need to check for null if(object.getJsonObject("sub1") != null && object

问题 For the last week I read documentation about vertx. What i don't get it's how vertx handlers are work? For example public class Client extends AbstractVerticle{ @Override public void start() throws Exception { final HttpClient httpClient = this.vertx.createHttpClient(); this.vertx.setPeriodic(1000, handler->{ httpClient.getNow(8080, "localhost", "/", responseHandler -> { System.out.println("response"); }); }); } } And server is: public class JdbcVertx extends AbstractVerticle{ @Override

问题 In Vert.x Web client manual there's an example of decoding an incoming JSON response into a POJO: client .get(8080, "myserver.mycompany.com", "/some-uri") .as(BodyCodec.json(User.class)) .send(ar -> { // Process the response }) Is there a way to decode an incoming JSON array into a collection of objects? 回答1: I don't believe you can use a BodyCodec to convert the content straight to a collection of objects. However you use Vert.x core Json class with the body as Buffer client .get(8080,

问题 How to enable auto redeploy in vertx application code when running in intellij idea? Intellij Settings for hot deployment of vertx application. 回答1: create a Run configuration (Application), set the Main class to io.vertx.core.Launcher. In the Program arguments write: run your-verticle-fully-qualified-name --redeploy=**/*.class --launcher-class=io.vertx.core.Launcher. To trigger the redeployment, you need to make the project or the module explicitly (Build menu → Make project). 来源： https:/

问题 I'm currently working on a project which requires TCP communication between an external system and an application which I will write (in Java). As we all know, this can easily be achieved using regular NIO. However, as part of this new project I'm working on, I have to use Vert.x to provide the TCP communication. Please refer to the image below: On the right, I have my application which runs as a TCP server waiting for a connection from the external system, on the left. I've read that to

问题 I'm trying to make VertX Mertrics work when running via the exec:java Maven plugin. All works as expected when I package the application into a fatjar and run it with java -jar fat.jar -conf config.json -Dvertx.metrics.options.enabled=true When I run it with mvn clean package exec:java -DskipTests I see: 2016-03-22 18:39:58.833 WARN i.v.c.i.VertxImpl:348 - Metrics has been set to enabled but no VertxMetricsFactory found on classpath I tried several approaches: adding io.vertx:vertx-dropwizard

问题 Is there any way (like in a symfony application) to list down all the available/register routes on a vertx server? I am facing an issue that my registered route is returning a 404 on running restassure tests. 回答1: Yes, but you have to write a bit of code to achieve that. // Example router setup Router router = Router.router(vertx); router.route(HttpMethod.GET, "/").handler(routingContext -> { routingContext.response().end("Root"); }); router.route(HttpMethod.GET, "/users").handler

问题 I am using vertx-web and trying to upload file. Here is my code: router.route().handler(BodyHandler.create().setUploadsDirectory("some/path/uploads")); router.post("/api/upload").handler(routingContext -> { for(FileUpload f : routingContext.fileUploads()){ System.out.println(f.fileName()); // logo.png } routingContext.response().end() }); Above code, uploads file to the given path, but the uploaded file extension is missing. File upload name: logo.png File saved name: 45edd7b4-5287-4fba-927e

问题 I am building a fat jar for a Vertx-Web application. I would like to serve some static files. I packaged the jar file, with webroot folder. See below screenshot for my jar structure: I was able to load the webroot/static/test.html file by doing: routingContext.response().sendFile("webroot/static/test.html"); However, I am not able to get the static handler to work. Below is my full code: package com.jdescript; import java.io.BufferedReader; import java.io.IOException; import java.io
