为什么我不能关闭maven插件中的tomcat 7 ?

时间：2022-09-03 22:57:05

I'm using tomcat7-maven-plugin 2.2 to run a webapp from command line (I'm on Windows 8.1, Java 1.7.0_51 and Maven 3.2.1).

我使用tomcat7-maven-plugin 2.2从命令行运行一个webapp(我在Windows 8.1、Java 1.7.0_51和Maven 3.2.1)。

This is the configuration (pretty straightforward, I guess):

这是配置(很简单，我猜):

<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.2</version>

    <configuration>
        <address>localhost</address>
        <port>8080</port>
        <path>/</path>
        <uriEncoding>UTF-8</uriEncoding>
    </configuration>
</plugin>

I run Maven with mvn tomcat7:run and it starts correctly, the server starts up, the webapp loads, and I can interact with it.
The command prompt in which I run Maven is busy showing Tomcat output (this looks fine to me):

我使用mvn tomcat7运行Maven:运行并正确启动，服务器启动，webapp加载，我可以与它交互。我运行Maven的命令提示符正忙着显示Tomcat的输出(这对我来说很好):

Then, I want to shutdown the server: I run mvn tomcat7:shutdown from a separate command prompt, but all I get is this:

然后，我要关闭服务器:我运行mvn tomcat7:从一个单独的命令提示符中关闭，但是我得到的只是这个:

"cmd" non è riconosciuto come comando interno o esterno,

That last line reads:

,最后一行写着:

"cmd" is not a recognized internal or external command, an executable or a batch file.

“cmd”不是一个公认的内部或外部命令、可执行文件或批处理文件。

I can stop Tomcat from the first command prompt hitting Ctrl+C, but since I need to pass all this others, I'd like to offer them a script to start the webapp and a script to stop it.

我可以阻止Tomcat在第一个命令提示符下按Ctrl+C，但是因为我需要传递所有这些，我想给他们一个脚本启动webapp和一个脚本来阻止它。

What's wrong? Is it a plugin error? Is it a configuration error on my side?

怎么了?它是一个插件错误吗?是我这边的配置错误吗?

EDIT

If I add <fork>true</fork> to the POM, the server crashes with this error:

如果我添加 true 到POM，服务器就会崩溃:

As far as I know you need to use Ctrl + c after starting Tomcat server with mvn tomcat7:run to shut it down as it's attached to the current Maven run.

据我所知，在使用mvn tomcat7启动Tomcat服务器后，您需要使用Ctrl + c:run关闭它，因为它连接到当前的Maven运行。

The shutdown goal is used to be called after e.g. performing some tests (integration tests) to finish all the job in a clean way.

关闭目标是在执行一些测试(集成测试)之后被调用的，以干净的方式完成所有的工作。

have a look at the fork option http://tomcat.apache.org/maven-plugin-2.2/tomcat7-maven-plugin/run-mojo.html#fork

看看这个fork选项，http://tomcat.apache.org/maven-plugin-2 /tomcat7-maven-plugin/run-mojo.html#fork ?

So with this option you are able to start embeded tomcat run some tests then shutdown.

因此，通过这个选项，您可以开始嵌入tomcat运行一些测试然后关闭。

An alternative is if the Tomcat maven plugin had a way to enable the shutdown port (default 8005) then you can just send the default shutdown string (default "shutdown") to shut it down.

另一种选择是，如果Tomcat maven插件有一种方法来启用关闭端口(默认的8005)，那么您可以只发送默认的关机字符串(默认的“关闭”)来关闭它。

Using a JMX client, the shutdown port is set to -1 when I run the plugin run goal.

使用JMX客户机，当我运行插件运行目标时，关闭端口设置为-1。
