使用Vert.x Maven插件快速创建项目的方法

使用Vert.x Maven插件快速创建项目的方法

本文介绍了使用Vert.x Maven插件快速创建项目的方法，分享给大家，具体如下：

文档地址： https://reactiverse.io/vertx-maven-plugin

已有项目添加该插件

在项目 pom.xml 目录，执行下面的命令即可添加：

mvn io.reactiverse:vertx-maven-plugin:1.0.17:setup

执行该命令后，在 pom.xml 中会增加下面的配置：

3.5.3

1.0.17

io.vertx

vertx-stack-depchain

${vertx.version}

pom

import

</dependencyManagement>

还有下面的插件：

io.reactiverse

vertx-maven-plugin

${vertx-maven-plugin.version}

vmp

initialize

package

true

自动引入的 vert.x 版本为 3.5.3，你可以通过在 mvn 命令增加 -DvertxVersion=3.4.0 这个参数来指定需要的版本。

从头创建空项目

首先你 必须创建一个目录 ，vert.x 插件不会自动给你创建目录，只会创建目录内的 src 和 pom.xml 等文件。

创建一个目录，进入该目录内，在该目录内执行下面的命令：

mvn io.reactiverse:vertx-maven-plugin:1.0.17:setup ^

-DprojectGroupId=org.acme ^

-DprojectArtifactId=acme-project ^

-DprojectVersion=1.0-SNAPSHOT ^

-Dverticle=org.acme.Foo ^

-Dverticle=io.vertx.sample.MyFirstVerticle ^

-Ddependencies=web

如果你使用的 linux 系统，将上面的 ^ 改为 \ 。

这里和上面相比增加了项目 GAV 的配置。

通过 -Dverticle=io.vertx.sample.MyFirstVerticle ，可以生成一个默认的 Verticle 类。

通过 -Ddependencies=web 可以指定你想加入的 vert.x 的依赖，这里写的名字都是缩写，具体对应关系看下面的介绍。

使用上面命令后，就创建了一个基础 vert.x 项目，在开始学习 vert.x 的时候，通过这种方式可以更快的创建基础项目。

-Ddependencies 对照表

源码： dependencies.json

下面 JSON 中的 labels 就是缩写名，groupId 和 artifactId 是对应的依赖。

打包项目

集成了 vert.x 插件后，打包变的极其容易，只需要下面的命令：

mvn clean package

通过这种方式就会打出一个 fat jar 包，可以直接通过 java -jar xxxx.jar 运行的包。

其他命令

除了上面这些，还有 vertx:run, vertx:debug, vertx:start, vertx:stop 命令，这些命令可以在不打 jar 包的情况下运行或者关闭项目。

常见问题

通过插件方式运行时，你经常会遇到下面的问题：

[INFO] 严重: java.net.BindException: Address already in use: bind

这种情况是因为使用类似 IDEA Maven 插件中的命令直接双击运行时，你无法关闭这个应用。如果你使用的纯命令行，直接 Ctrl+C 就能关闭。

使用 vertx:run 在命令行运行时可以直接关闭。

使用 vertx:start 运行时，需要通过 vertx:stop 关闭。

万一遇上无法关闭的情况，在 windows 中，可以用下面方式解决。

在命令行中，输入下面的命令：

jps -m

这个命令会列出所有运行的 jvm：

15248 Jps -m

2384 Launcher run io.vertx.sample.MyFirstVerticle redeploy-termination-period=1000 -Dvertx.id=5fd656fa-55a9-46b4-8d23-caa95f2e5032-redeploy

8208

11844 Launcher run io.vertx.sample.MyFirstVerticle redeploy-termination-period=1000 -Dvertx.id=bec46d01-d441-4949-a2d9-f8ffbe85f965-redeploy

14200 Launcher run io.vertx.sample.MyFirstVerticle --redeploy=F:\Git\my-first-vertx-app\target\classes/**/* --redeploy-scan-period=1000 redeploy-termi

nation-period=1000 --launcher-class=io.vertx.core.Launcher

7580 Launcher clean compile vertx:run

根据后面的信息找到你想关闭的 jvm。输入下面的命令(假设关闭 2384）：

taskkill /f /pid 2384

当相同端口的 jvm 关闭后，你就可以再次运行了。
