5.1. Using S2Container in component

When the component is dependent on S2Container into which it is registered, S2Container instance can be acquired by Property Injection. The component name of S2Container is "container".
The following service classes are created as an example. S2Container instance is be DI by automatic Property Injection.

module Example
  class Service
    def initialize
      @container = :container
    attr_reader :container

An execution script is created as follows.

require 's2container'
require 'example'

service = s2app.get(Example::Service)

This Example is located in example/example12
