spring-hibernate-20120924 2 | ========================= 3 | 4 | Course Outline 5 | -------------- 6 | 7 | Day 1 8 | 9 | - class design: 10 | Contact, Address 11 | ContactRepository (init, findAll, find, create, update, delete), AddressRepository (...) 12 | Setup (servlet context listener) 13 | 14 | - servlets / jsps: 15 | view all contact names, add a contact 16 | contact: edit name, address, delete contact 17 | 18 | - JDBC / JNDI / DataSource 19 | initialize tables in repositories, use raw sql 20 | 21 | Day 2 22 | 23 | - finish servlets 24 | 25 | - intro hibernate/jpa 26 | META-INF/persistence.xml, persistence-unit-ref in web.xml 27 | javax.persistence.{ Persistence, EntityManager } 28 | @Entity, @Column, @OneToOne 29 | Rewrite ContactRepository and AddressRepository (findAll, find, create, update, delete) and refactor 30 | 31 | Day 3 32 | 33 | - intro spring 34 | container-managed objects, dependency injection 35 | Spring MVC: controllers, @RequestMapping 36 | Spring JPA: JpaRepository, bytecode generation 37 | 38 | - refactor controller methods 39 | model, view, injecting request parameters, redirects 40 | 41 | - new class design: 42 | Contact, Person, Company, Office, Address 43 | how to represent polymorphism in jpa? 44 | @OneToMany, @ManyToOne, @ManyToMany 45 | 46 | - controllers: 47 | person: edit name, address, delete person 48 | company: edit name, view all offices, add an office, delete company 49 | 50 | Day 4 51 | 52 | - office front-end 53 | introduce UrlEntity helper 54 | 55 | - horrible bugs! 56 | why doesn't delete work? ... orphan removal 57 | lazy loaded associations, open session in view filter 58 | 59 | - discussion: Spring high level 60 | - discussion: Transactions and AOP 61 | - discussion: Entity versioning, optimistic locking 62 | 63 | - data constraints 64 | nullable, length 65 | Validation (ex: @NotBlank, all employees of a manager must work for the same company) 66 | 67 | Day 5 68 | 69 | - REST services 70 | more Spring MVC annotations 71 | Jackson 72 | 73 | 74 | JDBC Pain Points / ORM Requirements 75 | ----------------------------------- 76 | 77 | Code maintenance/evolution issues: 78 | - entity and sql can get out of sync as code evolves 79 | => objects must determine DB schema! 80 | - one must know sql 81 | => should be able to just get objects from somewhere / persist objects 82 | - no explicit relationship between entities (one-to-one???) 83 | => system must know relationships and constraints 84 | 85 | Flexibility/reuse issues: 86 | - code is tied to a specific SQL implementation (dialect) 87 | 88 | General ugliness/boilerplate: 89 | - very repetitive code, lots of try-finally 90 | => forget JDBC 91 | - checked SQLExceptions everywhere 92 | => forget JDBC 93 | - marshalling and unmarshalling is very clumsy 94 | 95 | Performance/correctness issues: 96 | - no joins 97 | - no transactions 98 | - no good way to "create table if not exists" 99 | 100 | Reference Material 101 |
