在ruby on rails中访问不同文件中具有相同名称的模块/类

# file1.rb
module Namespace1
  class MyClass
    def self.say_hello
      puts "Hello from Namespace1::MyClass"
    end
  end
end

# file2.rb
module Namespace2
  class MyClass
    def self.say_hello
      puts "Hello from Namespace2::MyClass"
    end
  end
end

# main.rb
require_relative 'file1'
require_relative 'file2'

Namespace1::MyClass.say_hello
Namespace2::MyClass.say_hello

# lib/module1/my_class.rb
module Module1
  class MyClass
    def self.say_hello
      puts "Hello from Module1::MyClass"
    end
  end
end

# lib/module2/my_class.rb

      puts "Hello from Module2::MyClass"
    end
  end
end

# main.rb
