编辑：我让应用程序使用 TorqueBox 工作，所以我猜这个问题与特立尼达有关。但是，我认为我对运行 Sinatra 应用程序的首选方式的猜测仍然有效。

我正在使用 JRuby、Bundler 和模块化风格。这是我的应用程序代码：

# myapp.rb
class MyApp < Sinatra::Base
  configure :development do
    register Sinatra::Reloader
  end

  set :server, 'trinidad'
  set :environment, :development
  set :logging, true
  #...
end

# config.ru
require 'bundler/setup'

Bundler.require(:default)

$: << File.dirname(__FILE__)

require 'myapp'

run MyApp

# Gemfile
source 'http://rubygems.org'

gem 'rack'
gem 'sinatra', :require => 'sinatra/base'
gem 'sinatra-contrib', :require => 'sinatra/reloader'
gem 'coffee-script'
gem 'neography'
gem 'gon-sinatra'
gem 'sass'
gem 'trinidad'

启动我的应用程序的正确方法是什么（即什么样的命令）？我正在使用 Trinidad，因为我读到它是 JRuby 应用程序的好解决方案（我无法让 TorqueBox 工作）。目前我正在通过“trinidad config.ru”运行我的应用程序，但它会引发以下错误消息：

我正在使用 Trinidad and Rack 的 1.4.1 版本、JRuby 的 1.7.0.preview1 和 Sinatra 的 1.3.3 版本。

如果我运行“bundle exec trinidad config.ru”，我会收到以下错误：

默认情况下不加载 ruby​​gems（至少使用 jruby --1.8），因此您可以在config.rurequire 'rubygems'之上添加，因为 JRuby（实际上是 JRuby-Rack）在单独的“运行时”中加载您的应用程序（一种新的ruby 进程，但在同一个 JVM 进程中）默认情况下。或者，您也可以使用rackup -s trinidad

至于调用机架配置和应用程序的 CLI 命令，kares 是对的。如果您不使用 Torquebox，则可以使用带有“-s trinidad”的“rackup”。

至于从机架配置中调用应用程序的 Ruby 命令，这就是我所做的。不确定这是否适用于您的情况，如果这是您正在寻找的，但无论 HTTP 处理程序如何，它都会有所帮助：

你有 MyApp，它混合在 Sinatra::Base 中。如果您将该类缩减为仅配置您的环境，并为每个页面加载运行“before do”和“after do”......但实际上并未处理和获取/发布调用；然后您可以创建专门的类来处理整个应用程序中的某些路径。这使用 Rack::Builder 的 map() 方法...

require 'myapp'
require 'mylanding'
require 'myauthentication'
require 'myautocomplete'
require 'mysearch'

#de run MyApp

map "/" do
    run MyLanding    #de Catch-all, which would have "get '/*' do" in it too.
end

map "/authentication/" do
    run MyAuthentication
end

map "/autocomplete/" do
    run MyAutocomplete
end

map "/search/" do
    run MySearch
end

然后在每个 My* 类中，执行以下操作：

class MyLanding < MyApp
  get "/*" do
    ..handle landing.. or see what's in the splat.
  end
end

class MyAuthentication < MyApp
  get "/sign/in" do
    ..present sign-in..
  end
  post "/sign/in" do
    ..handle sign-in..
  end
end

ETC...

您的子类具有对每个页面加载的整体 MyApp 处理，但添加路由，例如 /authentication/sign/in 由 MyAuthentication 的 /sign/in 处理。这是一种很酷的方式，可以让所有的子应用程序都使用相同的基础：MyApp。
