- created custom Exception Handler which creates better response
messages

* Code formatting

* formated pom.xml
replaced for loops with streams
fixed bug while getting all beans

* removed unnecessary code
changed repository type

* - added test for Spring Data REST APIs
- changed bad request return code
- formated code

* - added source code for ehcache article
- added ehcache dependency to pom.xml
