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：
|
1 |
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：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
<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>${vertx.version}</version> <type>pom</type> <scope> import </scope> </dependency> </dependencies> </dependencymanagement> |
还有下面的插件：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
<plugin> <groupid>io.reactiverse</groupid> <artifactid>vertx-maven-plugin</artifactid> <version>${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：
|
1 2 3 4 5 6 7 |
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：
|
1 |
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：
|
1 |
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）：
|
1 |
taskkill /f /pid 2384 |
当相同端口的 jvm 关闭后，你就可以再次运行了。
