Spring Data Repositories - A Deep Dive

I should change this project name.

• I started it from the repositories-deepdive from Oliver Gierke
• But it has not a lot in common now

This project is my sandbox to play with the following stack of techno:

• Java & groovy
• Spring
  • java spring configuration (no spring boot, not yet ;-) )
  • spring data repository
• hibernate via JPA
• activiti bpm
• spock
• gradle

quick howto

• only dependency: java 7 or 8 (maybe 6, not tested)
• clone the repo in direcotry <repo_home>
• #cd <repo_home>
• ./gradlew clean executeBookOrderProcess --daemon
• You should see some trace similar to this, but may vary as:
  • list of books in order is randomly picked
  • approval, if necessary, is random

Content of the project

• a few entity reprensting book, customer and bookorder
• a few repositories to have CRUD and a few more search on them
• a BookOrder Process in BPMN V2.0
• a few utils to test it:
  • loadSampleData
  • execute a bookOrderProcess
• some spock specifications, but not enough

Basic Idea

• Production code is in java
  • entity, service, repositories
  • I will try a full groovy version soon
• Utils and Tests are in groovy
  • Both cohabite nicelly with gradle and intellij IDEA
