Sample Apps: Spring data MongoDB and JSF Integration tutorial (PART 4)

Spring Data Repository:
Spring Data repository abstraction reduces the boilerplate code to write the data access layer of the application. Automatic implementation of Repository interfaces provides simple operation on mongoDB. It helps our product save and delete function make

MongoTemplate:
MongoTemplate offers convenience operations to create, update, delete and query for MongoDB documents and provides a mapping between your domain objects and MongoDB documents. In our application, since the spring data repository cannot fulfill the requirement of searching function, we use MongoTemplate to archive the searching capability.

Customizing Spring Data Repository
Since the searching of product cannot be easily implement with Spring data repository abstraction, we would like to implements the multi-criteira product search with MongoDBTemplate. To enrich Spring data repository with MongoTemplate, we can do the following to customize the repository:

ProductRepository.java

ProductRepositoryCustom.java

ProductRepositoryImpl.java

Data Model:
Product.java

Pricing.java

Detail.java

JSF Part:
common.xhtml

Search.xhml

ProductSearchCriteria.java

ProductSearchBean.java

Service Layer:
ProductService.java
