Essential Hybris Services

The services listed below are intensively used in SAP hybris development. It is not a full list of hybris services, but these are used almost in every project. In order to prioritize the services, I used the following bash command launched in the hybris home directory: I also extracted beans under @Resource and @Autowired annotations and combined the results with what I got from the bash script. The quick reference below helps with understanding the important concepts on how services work and where they are used. For all services, the corresponding beans have the same name (start with a lowercase as per beans naming convention)
