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：

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：

<properties>
 <vertx.version>3.5.3</vertx.version>
 <vertx-maven-plugin.version>1.0.17</vertx-maven-plugin.version>
</properties>
<dependencymanagement>
 <dependencies>
  <dependency>
   <groupid>io.vertx</groupid>
   <artifactid>vertx-stack-depchain</artifactid>
   <version>${vertx.version}</version>
   <type>pom</type>
   <scope>import</scope>
  </dependency>
 </dependencies>
</dependencymanagement>

还有下面的插件：

<plugin>
 <groupid>io.reactiverse</groupid>
 <artifactid>vertx-maven-plugin</artifactid>
 <version>${vertx-maven-plugin.version}</version>
 <executions>
  <execution>
   <id>vmp</id>
   <goals>
    <goal>initialize</goal>
    <goal>package</goal>
   </goals>
  </execution>
 </executions>
 <configuration>
  <redeploy>true</redeploy>
 </configuration>
</plugin>

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：

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。
