今天在javaeye论坛上看到有人有这个需求，顺手写了下。原理就是通过遍历Controllers目录，并用正则表达式取出Controller名和它所有的action。
@controllers=Hash.new
path="#{RAILS_ROOT}/app/controllers/"
Dir.new(path).entries.each do |f|
if !f.index('.rb').nil? and f.index('.rb')>0
controller=File.open(path+f.to_s)
s=controller.read
/class\s(.*)\s\</.match(s)
controller_name=$1.to_s
actions=[]
s.scan(/def\s(.*)\s/).each{ |action| actions<<(action[0]) }
@controllers[controller_name]=actions
controller.close
end
end
@controllers.each_pair do |name, actions|
actions.each do |action|
puts |name<<" "<<action
end
end
