java - Jetty Maven 在不同端口上插入多个 Web 应用程序

Question

如何使用最新版本的 jetty maven 插件在不同端口上运行多个 Web 应用程序？

org.eclipse.jetty:jetty-maven-plugin(撰写本文时的版本9.2.2.v20140723)。

例如，

foo.war -> localhost:8080/
bar.war -> localhost:8081/
baz.war -> localhost:8082/

The official documententation在 httpConnector

下说明这一点

name: 
   The name of the connector, which is useful for configuring contexts to 
   respond only on particular connectors.

太好了，所以我配置了一个名称，但是如何将其绑定(bind)到contextHandler？这是我到目前为止所拥有的

<plugin>
  <groupId>org.eclipse.jetty</groupId>
  <artifactId>jetty-maven-plugin</artifactId>
  <version>9.2.2.v20140723</version>
  <configuration>
    <connectors>
      <connector implementation="org.eclipse.jetty.server.nio.SelectChannelConnector">
        <port>8080</port>
        <name>instance_8080</name>
      </connector>
      <connector implementation="org.eclipse.jetty.server.nio.SelectChannelConnector">
        <port>8081</port>
        <name>instance_8081</name>
      </connector>
    </connectors>
    <contextHandlers>           
      <contextHandler implementation="org.eclipse.jetty.maven.plugin.JettyWebAppContext">
        <war>a.war</war>
        <contextPath>/</contextPath>
    </contextHandler>
    <contextHandler implementation="org.eclipse.jetty.maven.plugin.JettyWebAppContext">
      <war>b.war</war>
      <contextPath>/</contextPath>
    </contextHandler>
  </contextHandlers> 
</plugin>

这个not yet migrated wiki建议可以使用 WebAppContext 上的 connectorNames 属性来完成此操作，但这已不再可用。

查看文档:

http://www.eclipse.org/jetty/documentation/current/serving-webapp-from-particular-port.html

It is also possible to use an extension to the virtual host mechanism with named to connectors to make some web applications only accessible by specific connectors. If a connector has a name "MyConnector" set using the setName method, then this can be referenced with the special virtual host name "@MyConnector".

然后您可以暗示上下文，因为它将包含虚拟主机:

http://www.eclipse.org/jetty/documentation/current/configuring-virtual-hosts.html#different-virtual-hosts-different-contexts

使用@ConnectorName:

@ConnectorName A connector name, which is not strictly a virtual host, but instead will only match requests that are received on connectors that have a matching name set with Connector.setName(String).

上面链接中的配置基于单独的 jetty xml 配置文件。我还没有测试过这个，但你可以将它插入到你的 contextHandler (它有一个 setter)中:

<virtualHosts>
    <virtualHost>@instance_8080</virtualHost>
</virtualHosts>

这应该与相应的连接器绑定(bind)。

您也可以在 Java 中以编程方式执行此操作。
