3. 100% independent

4. 2005 Java EE Developer Spring Developer

5. 2012 Java EE Developer Spring Developer

6. Java EE vs Spring

7. Java EE with or without Spring !

8. You‘ll get your projects delivered with both stacks

9. I will discuss the topic on an architectural decision-maker level

10. Myths and Legends

11. Spring is an XML Hell

12. 0lines of XML for a Spring based Web Application

13. Spring is complex

14. You don‘t need the force to use Spring!

15. Spring has too many dependencies and makes WAR Files huge

16. Is this your runtime environment?

17. Spring is proprietary and not portable

18. Who has ported a usual JEE enterprise application as a

    drop-in?

19. A holistic examination is important

20. Ops Road-Map Code

21. Operational Aspects

22. Infrastructure

23. Infrastructure App Server Servlet Container Operations Team

24. Update Volume App Server Servlet Container Server Runtime Libraries like

    CDI, Servlet, JPA, JSF, ... Eventually JVM A lot of planning and testing is required Integration in Monitoring ...

25. Project Libs

26. Project Libs Hibernate ... Spring Development Team

27. Update Volume Hibernate ... Spring Dedicated, only single Libraries Ad

    Hoc Reduced test effort

28. Roundtrips Hibernate ... Spring App Server Servlet Container 2-4 Months

    2-3 Years

29. DEV OPS

30. DEV OPS vs ?

31. With Spring I achieve an increased flexibility by loosely coupling

    the infrastructure to the runtime

32. Coding

33. ? Are Dependency Injection and Testing game changers

34. Free your mind: we are in 2012 and not in

    2005 anymore

35. Dependency Injection and Testing are commodity

36. More important is the overall ecosystem

37. Spring builds upon Java EE Scheduling MVC REST JMX Testing

    Caching Profiles DI AOP TX JMS AOP JDBC ORM OXM Expression JSR-250 JSR-330 JTA JDBC 4.1 JPA 2.0 JSF 2.0 JSR-303 JMX 1.0

38. WebServices AMQP Roo Security OAuth Data JPA MongoDB Neo4j GemFire

    HBase Redis JDBC Splunk Querydsl HDFS MapReduce Hive Pig Cascading SI/Batch Social Twitter LinkedIn Facebook WebFlow Scheduling MVC REST JMX Testing Caching Profiles DI AOP TX JMS AOP JDBC ORM OXM Expression Batch Integration Mobile

39. Spring Data by example Data JPA MongoDB Neo4j GemFire HBase

    Redis JDBC Splunk Querydsl HDFS MapReduce Hive Pig Cascading SI/Batch

40. JPA 2 Query ... public class PersonDAO ... { private

    EntityManager em; public List<Person> findByFirstname(String firstname) { Query q = em.createQuery(“from Person p where p.firstname = :name “) .setParameter(“name“, firstname) return q.getResultList(); } }

41. JPA 2 Query ... public class PersonDAO ... { private

    EntityManager em; public List<Person> findByFirstname(String firstname) { Query q = em.createQuery(“from Person p where p.firstname = :name “) .setParameter(“name“, firstname) return q.getResultList(); } } You end up writing many simple queries

42. Spring Data @Repository public interface PersonRepository extends JpaRepository<Person, Long> {

    List<Kunde> findByFirstname(String firstname); }

43. Spring Data with QueryDSL @Repository public interface PersonRepository extends JpaRepository<Person,

    Long>, QueryDslPredicateExecutor<Person> { List<Kunde> findByFirstname(String firstname); } QPerson P = QPerson.person; BooleanExpression hasBirthday = p.birthday.eq(...); BooleanExpression livesInLinz = p.adress.city.eq("Linz"); Person result = personRepository.findAll(hasBirthday.and(livesInLinz));

44. Spring Data also adresses NoSQL, Big Data and Data Grids

    Data JPA MongoDB Neo4j GemFire HBase Redis JDBC Splunk Querydsl HDFS MapReduce Hive Pig Cascading SI/Batch

45. Where are the Java EE Answers to NoSQL, Mobile, Social,

    ...?

46. Keep in mind App Server Servlet Container Server Runtime Libraries

    like CDI, Servlet, JPA, JSF, ... Eventuell JVM A lot of planning and testing is required ! Ususal Roundtrip is 2-3 years !

47. Spring offers a consistent programming model and many helpful abstractions

    and utilities besides the basics

48. Road-Maps

49. Java EE 6 12 / 2009 Mid 2011 12 /

    2010 01 / 2012 02 / 2012 12 / 2009 Final Spec Release (GlassFish, no support) 12 / 2010 JBoss 6 (Web Profile, no support) Mid 2011 WebSphere 8 01 / 2012 WebLogic 12c 02 / 2012 JBoss 7.1

50. !The Java EE venors took 1,5 years for the first

    fully professionally supported container

51. Java EE 7: 3,5 years later 12 / 2009 Final

    Spec Release JEE 6 Q2 / 2013 Final Spec Release JEE 7

52. News around Java EE 7 Cloud Plattform will be delayed

    to Java EE 8 Social API is on a halt JCache won‘t make it in Java EE 7

53. What is left?

54. JAX-WS 2.0 CDI 1.1 JMS 2.0 after 11 years JPA

    2.1 Servlet 3.1 JSF 2.2 .... Java EE 7

55. 12 / 2009 Spring 3.0 12 / 2011 Spring 3.1

    12 / 2012 Spring 3.2 Spring since 2009 12 / 2009 12 / 2011 End 2012 Full professional support Available on all containers right away

56. Some math Java EE API Release 12 / 2009 0

    months Server Mid 2011 18 months Available in organisations Mid 2013 18 + 24 months API is available in production API is available in production 42 months 3,5 years

57. The same math Spring 3.0 API Release 12 / 2009

    0 months Available in organisations 3 / 2010 3 months API is available in production API is available in production 3 months

58. Spring offers an innovative and reliable Road-Map with immediate availability

    and support
