Jetty 9.0.6中没有热部署 [英] No hot deployment in Jetty 9.0.6
问题描述
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:
I have set up a Jetty context by a context.xml for using virtual hosts. So my directory structure looks like this:
webapps
--mycontext.xml
--mycontext.war
现在,当我上传新的战争时,不再发生热部署.仅当我修改mycontext.xml时才会发生.当我没有mycontext.xml时,情况并非如此.
Now when i upload a new war, no hot deployment occurs any more. It only happens when i modify mycontext.xml. That was not the case when i worked without a mycontext.xml.
这是mycontext.xml的内容
Here is the content of 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">/</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>
有什么想法可以通过更新war文件来重新获得热部署?
Any ideas how i regain hot deployment by updating the war file?
推荐答案
您需要将mycontext.xml放在服务器的contexts目录中.您还可能需要在etc/jetty-deploy.xml中为webapps目录中的war文件启用热部署,如
You need to put your mycontext.xml in the contexts directory of your server. Also you probably need to enable hot deployment in etc/jetty-deploy.xml for the war files in webapps directory as mentioned here. As you can see the configuration enables the hot deployment
......
<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
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的名称和位置
Please note how I have supplied the war file name and location
<Set name="war"><SystemProperty name="jetty.home"/>/webapps/mycontext.war</Set>
jetty.home/etc/jetty-deploy.xml
jetty.home/etc/jetty-deploy.xml
<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">

使用此配置,当我将修改后的mycontext.war放到webapps中时,很高兴地跳船 重新部署战争.
With this configuration, when I put a modified mycontext.war in webapps, jetty happily redeploys the war.
