将jRuby部署到Tomcat的子文件夹中 [英] jRuby deployment into a subfolder in Tomcat

问题描述

在使用webbrick作为网络服务器开发jRuby应用程序时，我的所有代码都是用 http：// localhost：3000 编写的

While developing a jRuby application using webbrick as the webserver, all my code is written with http://localhost:3000 as the root.

部署到Tomcat时，我创建了一个WAR文件，并在webapps /文件夹下创建了一个子文件夹：localhost：8080 / project_name /

When deploying to Tomcat, I create a WAR file and it creates a subfolder under the webapps/ folder: localhost:8080/project_name/

这会导致我的代码出现很多问题。我可以在我的ruby route.rb文件中做些什么来解决这个问题？

This causes a load of problems with my code. Is there anything I can do in my ruby routes.rb file to deal with this?

我应该在Tomcat中使用某种虚拟主机吗？

Should I resort to using some sort of virtual host in Tomcat?

推荐答案

JRuby-Rack中有代码可以解决这个问题。根据Tomcat和/或Rails的版本，它可能无法正确检测到额外的上下文路径。

There is code in JRuby-Rack to deal with this. Depending on the version of Tomcat and/or Rails, it may not be detecting the extra context path correctly.

本应生效的环境变量称为 ENV ['RAILS_RELATIVE_URL_ROOT'] 。您可能会在启动时打印出该表达式的值，并查看在Tomcat中运行时它是否被设置。

The environment variable that is supposed to take effect is called ENV['RAILS_RELATIVE_URL_ROOT']. You might print out the value of that expression during boot time and see whether it's getting set when you run in Tomcat.

有问题的代码在这里：

您使用的Tomcat，Rails和JRuby-Rack版本将有助于进一步诊断问题。

The versions of Tomcat, Rails and JRuby-Rack you're using would help diagnose the problem further.
