Spring Data Repositories A Deep Dive Oliver Gierke

Hands on
Sample code https://github.com/olivergierke/ repositories-deepdive
Step 0 Initial project setup
Summary Use kickstart projects to ease setup
Step 1 Basic JPA infrastructure setup
"Persistence technology of choice is JPA. e application uses JavaConfig
and sample data contained in data.sql.
Summary Easy setup through JavaConfig XML-less JPA configuration
Step 2 Quickstart
"e implementation of the persistence layer will be based on
the Spring Data repositories abstraction. Customers can be saved, looked up by their id, email address.
Summary Interface-based programming model No implementation required Queries derived from
method names
Step 3 Extended CRUD methods
" Customers can be deleted and obtained all at once.
Summary Switched to CrudRepository Exposed CRUD methods Broad API exposed
Step 4 Pagination
"Customers can be accessed page by page.
Summary Switched to PagingAndSortingRepository Exposed CRUD methods and paging ones
Broad API exposed
Step 5 Re-declaring existing CRUD methods
"CustomerRepository.findAll() should rather return a List. e transaction timeout for
save(…) should be customized to 10 seconds.
Summary Re-declare methods to customize Return types Annotation config (Tx,
Locking)
Step 6 Introducing a read-only repository base interface
"Products shall be accessible in read-only mode only.
Summary Craft custom base interface Annotation config (Tx, Locking)
Step 7 Using manually defined queries
"As a user, I want to look up products by
their custom attributes.
Summary @Query annotation JPA named queries Spring Data named queries
Step 8 Flexible predicate execution
"As a user, I want to search for customers by
firstname, lastname, email address and any combination of them
Summary Querydsl - type safe queries for Java QuerydslPredicateExecutor
Side track: Repository proxies
Proxy mechanism Using Spring's JDK proxy support Bootstrap through Factory
Spring FactroyBean / CDI XML namespace / @EnableRepositories
Proxy mechanism Query interface CRUD implementation class QueryDslPredicateExecutor Custom implementation
extension
Step 9 Custom implementations for repositories
"As an admin user, I'd like to delete all products
beyond a given price.
Summary Provide custom implementation Base class support (Querydsl)
