1. Introduction
|
|
---------------
|
|
- Project structure
|
|
- Spring configuration
|
|
- Services
|
|
- Test cases
|
|
|
|
2. Issues
|
|
---------
|
|
- Generics, simple queries, pagination (no metadata), is new?, arbitrary queries
|
|
- Approach: step by step refactoring -> introduce Spring Data JPA
|
|
|
|
5. AccountRepository
|
|
--------------------
|
|
- replace save(…)
|
|
- findByCustomer -> show log -> method created from method name
|
|
- explain proxy mechanism, method signature possibilities (@Param, return types)
|
|
|
|
4. Explain general proxy mechanism, SimpleJpaRepository
|
|
-------------------------------------------------
|
|
- show JpaRepository interface
|
|
- findAll(Pageable pageble)
|
|
|
|
3. CustomerRepository
|
|
---------------------
|
|
- add dependency to CustomerServiceImpl
|
|
- replace findById, findAll, save
|
|
- run test
|
|
- explain extended method signature possibilities (Pageable, Sort)
|
|
- replace findByLastname(Pageable pageable) in CustomerService
|
|
|
|
6. First summary
|
|
----------------
|
|
- implementation got obsolete
|
|
- switch to after package
|
|
|
|
7. Querydsl / Specifications
|
|
----------------------------
|
|
- Introduce Querydsl
|
|
- Show Maven setup
|
|
- Show predicates
|
|
- Integrate test case
|
|
|
|
7. Custom implementation
|
|
------------------------
|
|
- copy interface and implementation (hint to visibility)
|
|
- adapt AccountRepository
|
|
- copy test case
|
|
- explain implementation class lookup
|
|
|
|
8. JDBC implementation (optional)
|
|
-----------------------
|
|
- copy implementation -> configuration necessary
|
|
- copy XML
|
|
- run tests -> fail (shows that JDBc bean is used)
|
|
- fix SQL by adding FROM -> tests run again
|
|
|
|
9. Auditing (optional)
|
|
-----------------------
|
|
- show auditing test from Hades sample project
|
|
|
