IntelliJ和Vertx：如何运行org.vertx.java.deploy.impl.cli.Starter？ [英] IntelliJ and Vertx: How to run org.vertx.java.deploy.impl.cli.Starter ?
问题描述
我在Maven项目中有以下代码：
I have the following code inside Maven project:
package hello;
import org.vertx.java.core.Handler;
import org.vertx.java.core.http.HttpServerRequest;
import org.vertx.java.deploy.Verticle;
public class Server extends Verticle {
public void start() {
vertx.createHttpServer().requestHandler(new Handler<HttpServerRequest>() {
@Override
public void handle(HttpServerRequest req) {
System.out.println("Got request: " + req.uri);
System.out.println("Headers are: ");
for (String key : req.headers().keySet()) {
System.out.println(key + ":" + req.headers().get(key));
}
req.response.headers().put("Content-Type", "text/html; charset-UTF-8");
req.response.end("<html><body><h1>Hello from vert.x!</h1></body></html>");
}
}).listen(4000);
}
}
我在pom.xml中也有以下依赖项：
I also have the following dependency in pom.xml:
<dependency>
<groupId>io.vertx</groupId>
<artifactId>vertx-core</artifactId>
<version>3.4.1</version>
</dependency>
<dependency>
<groupId>org.vert-x</groupId>
<artifactId>vertx-platform</artifactId>
<version>1.2.3.final</version>
</dependency>
我尝试使用以下配置在IntelliJ中运行Java应用程序：
I try to run Java application in IntelliJ with the following configuration:
我收到很多错误：
错误：（7,8）java：hello.Server不是抽象的，并且不会覆盖
io.vertx.core.Verticle中的
抽象方法stop（io.vertx.core.Future）错误： （12,57）java：找不到符号
符号：变量uri位置：变量req类型
io.vertx.core.http.HttpServerRequest错误：（14,48）java：不能找
符号符号：方法keySet（）位置：接口
io.vertx.core.MultiMap错误：（17,20）java：找不到符号
符号：变量响应位置：
io.vertx.core.http.HttpServerRequest类型的变量req错误：（18,20）java：找不到
符号符号：v ariable响应位置：
的变量req io.vertx.core.http.HttpServerRequest错误：（9,9）java：找不到
符号符号：变量vertx location：class hello.Server
Error:(7, 8) java: hello.Server is not abstract and does not override abstract method stop(io.vertx.core.Future) in io.vertx.core.Verticle Error:(12, 57) java: cannot find symbol
symbol: variable uri location: variable req of type io.vertx.core.http.HttpServerRequest Error:(14, 48) java: cannot find symbol symbol: method keySet() location: interface io.vertx.core.MultiMap Error:(17, 20) java: cannot find symbol
symbol: variable response location: variable req of type io.vertx.core.http.HttpServerRequest Error:(18, 20) java: cannot find symbol symbol: variable response location: variable req of type io.vertx.core.http.HttpServerRequest Error:(9, 9) java: cannot find symbol symbol: variable vertx location: class hello.Server
然而，当我从这里下载vert.x jar文件时：
http://vertx.io/download/
However, when I download vert.x jar files from here: http://vertx.io/download/
并将它们放入项目结构中，然后相同代码编译成功。
and put them in the project structure, then the same code compiles successfully.
可能我需要在pom.xml中有另一个依赖项，但我不知道它应该是什么。
Probably I need another dependency in pom.xml, but I don't know what it should be.
推荐答案
你不应该有依赖：
<dependency>
<groupId>org.vert-x</groupId>
<artifactId>vertx-platform</artifactId>
<version>1.2.3.final</version>
</dependency>
因为它与Vert.x 1.2相关，而你的应用程序与3.x相关。在这种情况下，您的主要类应该是：
Since it related to Vert.x 1.2 and your application in on 3.x. In this case your main class should be:
io.vertx.core.Launcher
或者你可以从那里添加 main 方法并进行调试，例如：
Alternatively you could add a main method and debug from there, for example:
public class Server extends Verticle {
public static void main(String[] args) {
Vertx.vertx().deployVerticle(new Server());
}
}
现在您无需担心添加启动器配置文件，只需右键单击并运行/调试。
Now you don't need to worry about adding launcher profiles, just right click and run/debug.
