如何将jsp文件热部署到tomcat? [英] How to hot-deploy jsp file to tomcat?

问题描述

我不想每次在JSP文件中进行一些编辑时都生成一个war文件.我希望事情能与PHP一起使用.如何热部署到tomcat服务器?热部署是Java标准吗?

I don't want to build a war file each time I make a little edit in a JSP file. I want things to work like with PHP. How can I hot-deploy to a tomcat server? Is hot-deploy a java standard?

可以在我的软件的发行版本中使用这种热部署吗?

Can this kind of hot-deploy be used in a released version of my software ?

推荐答案

由于链接的问题并未真正涉及细节...

As the linked question doesn't really go into details ...

在$CATALINA_BASE/conf/server.xm l中，您需要配置本地服务器以解压缩WAR.这是我的开发服务器中的示例:

In $CATALINA_BASE/conf/server.xml, you need to configure the local server to unpack WARs. Here's the example from my development server:

 <Host appBase="webapps" autoDeploy="true" deployOnStartup="true" 
       deployXML="true" name="localhost" unpackWARs="true">

默认情况下，Tomcat将检查对JSP文件的更改.实际上，您必须针对生产进行更改，如这里.

By default, Tomcat will check for changes to JSP files. In fact, you have to change that for production, as described here.

在进行了这些更改之后，您将在$CATALINA_BASE/work/Catalina/localhost中找到您的Web应用程序(再次假设是默认安装；如果要配置服务器名称，则不会是localhost).就地编辑文件，更改将在您下次加载页面时显示.

With these changes in place, you will find your web-app in $CATALINA_BASE/work/Catalina/localhost (assuming, again, a default install; if you're configuring server name, it won't be localhost). Edit the file in-place, and the changes will appear when you load the page next.

这种热部署可以在我的软件的发行版中使用

Is this kind of hot-deploy can be used in a release versioin of my software

如果您想避免难以追踪的错误，那就不要.

Not if you want to avoid hard-to-track-down bugs.
