grails：在开发中为嵌入式tomcat添加上下文 [英] grails: add context to embedded tomcat in development

问题描述

在制作过程中，我已经设置了一个外部文件夹来通过编辑server.xml来上传和显示
的图片：

In production I have setup an external folder to upload and display images from by editing server.xml:

<Service name="Catalina">

   <Connector port="80" protocol="HTTP/1.1"
             connectionTimeout="20000"
             URIEncoding="UTF-8"
             redirectPort="443" />

   <Engine name="Catalina" defaultHost="localhost">

     <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
        resourceName="UserDatabase"/>

     <Host name="localhost"  appBase="webapps"
       unpackWARs="true" autoDeploy="true"
       xmlValidation="false" xmlNamespaceAware="false">

       <Context docBase="/opt/winmail_storage/imgs" path="/imgs"/>

     </Host>
   </Engine>
 </Service>

我试图通过编辑_Events.groovy在开发中做同样的事情：

I am trying to do the same thing in development by editing _Events.groovy :

eventConfigureTomcat = {tomcat ->
       def ctx = tomcat.addContext("/imgs" , "/tmp/images")
}

我也试过

I also tried

eventConfigureTomcat = {tomcat ->
       def ctx = tomcat.addContext("/appName/imgs" , "/tmp/images")
}

这不起作用，imgs目录无法通过以下方式访问：
http：/ / host / appName / imgs 任何想法如何正确地做到这一点？

this is not working, the imgs directory is not accessible via : http://host/appName/imgs any idea how I can do this correctly?

推荐答案

最后得到它感谢grails邮件列表：

finally got it thanks to the grails mailing list:

eventConfigureTomcat = {tomcat ->

def context = tomcat.addWebapp('/acrm/imgs' , '/tmp/images')
def loader = new WebappLoader(tomcat.class.classLoader)
loader.addRepository(new File('/home/mohadib/workspace/acrm/lib').toURI().toURL().toString())
loader.container = context
context.loader = loader
}
