我已经通过 context.xml 设置了一个 Jetty 上下文以使用虚拟主机。所以我的目录结构是这样的：

webapps
--mycontext.xml
--mycontext.war

现在，当我上传新战争时，不再发生热部署。它仅在我修改 mycontext.xml 时发生。当我在没有 mycontext.xml 的情况下工作时，情况并非如此。

这是 mycontext.xml 的内容

<?xml version="1.0"  encoding="ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_0.dtd">

<Configure class="org.eclipse.jetty.webapp.WebAppContext">

 <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
 <!-- Required minimal context configuration :                        -->
 <!--  + contextPath                                                  -->
 <!--  + war OR resourceBase                                          -->
 <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
 <Set name="contextPath">/</Set>
 <Set name="war"><Property name="jetty.webapps" default="."/>/mycontext.war</Set>

 <Set name="virtualHosts">
   <Array type="String">
     <Item>example.com</Item>
      <Item>www.example.com</Item>
      <Item>localhost</Item>
     <Item>127.0.0.1</Item>
   </Array>
 </Set>
</Configure>

任何想法我如何通过更新战争文件重新获得热部署？

您需要将 mycontext.xml 放在服务器的 contexts 目录中。此外，您可能需要在 etc/jetty-deploy.xml 中为 webapps 目录中的 war 文件启用热部署，如此处所述。如您所见，配置启用了热部署

......
 <Set name="monitoredDirName"><Property name="jetty.home" default="." />/webapps</Set>
.....

以下是对我有用的配置

jetty.home/contextx/mycontext.xml

<?xml version="1.0"  encoding="ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_0.dtd">

<Configure class="org.eclipse.jetty.webapp.WebAppContext">

 <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
 <!-- Required minimal context configuration :                        -->
 <!--  + contextPath                                                  -->
 <!--  + war OR resourceBase                                          -->
 <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
 <Set name="contextPath">/mycontext</Set>
 <Set name="war"><SystemProperty name="jetty.home"/>/webapps/mycontext.war</Set>

 <Set name="virtualHosts">
   <Array type="String">
     <Item>example.com</Item>
      <Item>www.example.com</Item>
      <Item>localhost</Item>
     <Item>127.0.0.1</Item>
   </Array>
 </Set>
</Configure>

请注意我是如何提供战争文件名和位置的

 <Set name="war"><SystemProperty name="jetty.home"/>/webapps/mycontext.war</Set>

jetty.home/etc/jetty-deploy.xml

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">

          </Arg>
        </Call>

        </New>
      </Arg>
    </Call>
</Configure>

有了这个配置，当我把修改后的 mycontext.war 放到 webapps 中时，jetty 很高兴地重新部署了 war。
