Question

我已经通过context.xml设置了一个Jetty上下文来使用虚拟主机。所以我的目录结构如下所示：

webapps
--mycontext.xml
--mycontext.war

现在，当我上传新战争时，不再发生热部署。它只发生在我修改mycontext.xml时。当我没有mycontext.xml工作时，情况并非如此。

以下是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>

有关如何通过更新war文件重新获得热部署的任何想法？

Answer 1

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，如上所述here。如您所见，配置启用了热部署

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

以下是适用于我的配置

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>

请注意我如何提供战争文件名称和位置

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

jetty.home的/ etc /码头-deploy.xml

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

              <Set name="scanInterval">1</Set>
              <Set name="extractWars">true</Set>
            </New>
          </Arg>
        </Call>

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

使用这种配置，当我在webapps中放置修改后的mycontext.war时，愉快地使用jetty 重新部署战争。

Jetty 9.0.6中没有热部署
