Maven 运行 通过命令行指定 contextPath 的 Jetty 插件

Maven run Jetty Plugin by command line specifying contextPath

我在使用 IntelliJ IDEA CE,我是 运行 一个 war 通过 Maven Jetty 插件的应用程序。

我的 pom.xml 中没有插件(我也不想),所以我 运行 直接使用此命令作为 Web 服务器:

mvn org.eclipse.jetty:jetty-maven-plugin:9.4.26.v20200117:run-exploded

它工作正常,但它不应用在 xml 文件 src/main/webapp/META-INF/context.[=31= 中指定的 contextPath ]

我想从终端命令指定正确的上下文路径。 documentation 对此没有具体说明。 我所做的测试(没有任何成功的结果)如下:

mvn org.eclipse.jetty:jetty-maven-plugin:9.4.26.v20200117:run-exploded -Dproject.artifactId='/project'
mvn org.eclipse.jetty:jetty-maven-plugin:9.4.26.v20200117:run-exploded -DcontextPath='/project'
mvn org.eclipse.jetty:jetty-maven-plugin:9.4.26.v20200117:run-exploded -Dconfiguration.webApp.contextPath="/project"
mvn org.eclipse.jetty:jetty-maven-plugin:9.4.26.v20200117:run-exploded -Djetty.configuration.webApp.contextPath="/project"

我错过了什么?

这最终是一个通用的 Maven 技巧,而不是特定于 Jetty 的技巧。

换句话说,如何弄清楚您可以使用 maven 插件做什么。

$ mvn org.eclipse.jetty:jetty-maven-plugin:9.4.26.v20200117:help
...(snip)...

jetty:help
  Display help information on jetty-maven-plugin.
  Call mvn jetty:help -Ddetail=true -Dgoal=<goal-name> to display parameter
  details.

那么让我们看看目标的细节是什么 :run-exploded ...

  Jetty maven plugins

jetty:run-exploded
  This goal is used to assemble your webapp into an exploded war and
  automatically deploy it to Jetty.
  
  Once invoked, the plugin runs continuously, and can be configured to scan for
  changes in the pom.xml and to WEB-INF/web.xml, WEB-INF/classes or WEB-INF/lib
  and hot redeploy when a change is detected.
  
  You may also specify the location of a jetty.xml file whose contents will be
  applied before any plugin configuration. This can be used, for example, to
  deploy a static webapp that is not part of your maven build.

  Available parameters:

    contextHandlers
      List of other contexts to set up. Consider using instead the <jettyXml>
      element to specify external jetty xml config file. Optional.

    contextXml
      Location of a context xml configuration file whose contents will be
      applied to the webapp AFTER anything in <webApp>.Optional.

    dumpOnStart (Default: false)
      Use the dump() facility of jetty to print out the server configuration to
      logging
      User property: dumponStart

    excludedGoals
      List of goals that are NOT to be used

    httpConnector
      A ServerConnector to use.

    jettyXml
      Comma separated list of a jetty xml configuration files whose contents
      will be applied before any plugin configuration. Optional.

    loginServices
      List of security realms to set up. Consider using instead the <jettyXml>
      element to specify external jetty xml config file. Optional.

    nonBlocking (Default: false)
      Determines whether or not the server blocks when started. The default
      behavior (false) will cause the server to pause other processes while it
      continues to handle web requests. This is useful when starting the server
      with the intent to work with it interactively. This is the behaviour of
      the jetty:run, jetty:run-war, jetty:run-war-exploded goals.
      
      If true, the server will not block the execution of subsequent code. This
      is the behaviour of the jetty:start and default behaviour of the
      jetty:deploy goals.

    reload (Default: automatic)
      reload can be set to either 'automatic' or 'manual' if 'manual' then the
      context can be reloaded by a linefeed in the console if 'automatic' then
      traditional reloading on changed files is enabled.
      User property: jetty.reload

    requestLog
      A RequestLog implementation to use for the webapp at runtime. Consider
      using instead the <jettyXml> element to specify external jetty xml config
      file. Optional.

    scanIntervalSeconds (Default: 0)
      The interval in seconds to scan the webapp for changes and restart the
      context if necessary. Ignored if reload is enabled. Disabled by default.
      Required: Yes
      User property: jetty.scanIntervalSeconds

    server
      A wrapper for the Server object

    skip (Default: false)
      Skip this mojo execution.
      User property: jetty.skip

    stopKey
      Key to provide when stopping jetty on executing java -DSTOP.KEY=<stopKey>
      -DSTOP.PORT=<stopPort> -jar start.jar --stop

    stopPort
      Port to listen to stop jetty on executing -DSTOP.PORT=<stopPort>
      -DSTOP.KEY=<stopKey> -jar start.jar --stop

    supportedPackagings
      Per default this goal support only war packaging. If your project use an
      other type please configure it here.

    systemProperties
      System properties to set before execution. Note that these properties will
      NOT override System properties that have been set on the command line or
      by the JVM. They WILL override System properties that have been set via
      systemPropertiesFile. Optional.

    systemPropertiesFile
      File containing system properties to be set before execution Note that
      these properties will NOT override System properties that have been set on
      the command line, by the JVM, or directly in the POM via systemProperties.
      Optional.
      User property: jetty.systemPropertiesFile

    useProvidedScope (Default: false)
      Whether or not to include dependencies on the plugin's classpath with
      <scope>provided</scope> Use WITH CAUTION as you may wind up with duplicate
      jars/classes.

    war (Default: ${project.build.directory}/${project.build.finalName})
      The location of the war file.
      Required: Yes

    webApp
      An instance of org.eclipse.jetty.webapp.WebAppContext that represents the
      webapp. Use any of its setters to configure the webapp. This is the
      preferred and most flexible method of configuration, rather than using the
      (deprecated) individual parameters like 'tmpDirectory', 'contextPath' etc.

这告诉您 webApp 的配置是您设置 contextPath

的地方

不幸的是,这是一个复杂的对象,您不能在命令行中指定它。

因此请编辑您的 pom.xml 以包含它。

  <build>
    <pluginManagement>
      <plugins>
        <plugin>
          <groupId>org.eclipse.jetty</groupId>
          <artifactId>jetty-maven-plugin</artifactId>
          <configuration>
            <webApp>
              <contextPath>/foo</contextPath>
            </webApp>
          </configuration>
        </plugin>
  ...

  2. 命令行如下:

mvn jetty:run -Dcontext=/abc
