}

Application is the bootstrap of a Rhapsody app

Root is pointer of app for config, controller and handler registry

normal bean can have a name, only if there is a prime bean with same name and type, and this method will do nothing

if a normal bean doesn't a name

  1. there is only one loaded bean with the same type, this method do nothing

  2. there are more than one loaded bean with the same type, error and exit

  3. there is no loaded bean with the same type, this method with initialize a new bean

Start with the Root, Get Fields of Root

First, we load "PrimeBean", which mean field define in config, are basic of all bean 

PrimeBean include all component Fields in config, which can defined unique name

Then, we load BeanMethodOut, which mean result of "bean method", however, what's bean method? 

Bean method mean methods defined in config, return only bean(component), and all parameters can init with dependency injection

returned value of Bean method is same as PrimeBean

parameter value is same as normal field

And then, we load normal bean recursively
