ruby on rails initialized 的顺序

最近做相关项目，遇到了这个难题。经查证，得答案如下：

1. config/preinitializer.rb
2. config/environment.rb
3. config/environments/#{RAILS_ENV}.rb
4. plugin initialization
5. gem initialization
6. config/initializer/*.rb
7. all after_initialize blocks, in the order they were defined in (so same order as above)
8. any junk left below the Rails::Initializer.run call/block in environment.rb

以上内容，仅供参考
