Is Spring the new legacy as quite a few people tell you on their blogs? I disagree on many levels. Throughout this session I will holistically detail on many levels without any polemics why I do recommend using the Spring Framework and it's ecosystem. Aspects that will be covered include: operational impacts, ecosystem, coding and road maps.

1. ?
Why do I recommend
the
Spring Framework
to my customers

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. 0 lines 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 Code Road-Map

21. Operational
Aspects

22. Infrastructure

23. Infrastructure
App Server
Servlet
Container
Operations Team

24. Update Volume
Libraries like
Server
App Server Runtime CDI, Servlet,
JPA, JSF, ... A lot of
planning
and testing
Servlet is required
Container Eventually
Integration
in Monitoring
JVM
...

25. Project Libs

26. Project Libs
Spring
Hibernate
...
Development Team

27. Update Volume
Spring Ad Hoc
Dedicated,
only single
Hibernate Reduced
Libraries
test effort
...

28. Roundtrips
Spring
App Server
Hibernate 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
DI AOP TX JMS AOP JDBC ORM OXM Expression
Scheduling MVC REST JMX Testing Caching Profiles
JTA JSR-250 JSR-330 JDBC 4.1
JSF 2.0 JPA 2.0 JSR-303 JMX 1.0

38. Data
Batch
JPA MongoDB Neo4j GemFire Social
HBase
Integration Twitter
Redis JDBC Splunk Querydsl
LinkedIn
Facebook
HDFS MapReduce Hive
Mobile
Pig Cascading SI/Batch
Security
WebFlow WebServices AMQP Roo
OAuth
DI AOP TX JMS AOP JDBC ORM OXM Expression
Scheduling MVC REST JMX Testing Caching Profiles

39. Data
JPA MongoDB Neo4j GemFire
HBase
Redis JDBC Splunk Querydsl
Spring Data
HDFS MapReduce Hive
by example
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
Server
App Server Runtime
Libraries like A lot of
planning
CDI, Servlet, and testing
Servlet JPA, JSF, ... is required
Container Eventuell
JVM
! 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 12 / 2010 Mid 2011 01 / 2012 02 / 2012

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

JAX-WS 2.0
Java EE 7
JMS 2.0 CDI 1.1

containers right
12 / 2012 Spring 3.2 away

56. Some math
Java EE
API Release 12 / 2009 0 months
Server Mid 2011 18 months
Available in
Mid 2013 18 + 24 months
organisations
42 months
API is available in production
3,5 years

57. The same math
Spring 3.0
API Release 12 / 2009 0 months
Available in
3 / 2010 3 months
organisations
API is available in production 3 months

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