Created service layer with generic service and extended to more specific services. Autowired all beans. Added Jackson Mapper for REST api to serve JSON. Added new view for home page. Updated Entity classes to resolve infinite json recursion issues. Updated all POM files and spring configuration files to load beans from the adjacent layer. Separated all concerns.
Uncommented the end of the unit tests.
Added some service tests testing findByCriteria, saveOrUpdate, and findAllEntities in the post service. Tested NOT_EQUALS, EQUALS, and CONTAINS.
