A Brief History of Spring

§ SpringSource created by the founders of the Spring Framework • Originally Interface 21, renamed SpringSource in 2008 • Employed most Spring developers and provided training, consulting,

and commercial support. • Acquisitions included G2One and Cloud Foundry

§ Acquired by VMWARE 2009 § In April 2013 VMware, and its parent company EMC Corporation,

formally created a joint venture with GE called . • All of VMware's application-oriented products, including Spring were

transferred to Pivotal.

Some things stay the same… “I believe that Spring is unique, for several reasons: !

It addresses important areas that many other popular frameworks don‘t

Spring is both comprehensive and modular. Spring is designed from the ground up to help you write code

that's easy to test. Spring is an increasingly important integration technology” !! - Rod Johnson, TheServerSide.com, 2005

Introducing Spring Framework 4.0

§ Ready for new application architectures • embedded web servers and non-traditional datastores

• lightweight messaging and WebSocket-style architectures

• custom asynchronous processing with convenient APIs

§ A new baseline • Java SE 6+ (minimum API level: JDK 6 update 18, ~ early 2010)

• Java EE 6+ (Servlet 3.0 focused, Servlet 2.5 compatible at runtime)

• all deprecated packages removed

• many deprecated methods removed as well

Spring Framework 4 and Java 8

§ First-class support for Java 8 language and API features • lambda expressions

• method references

• JSR-310 Date and Time

• repeatable annotations

• parameter name discovery

§ Full runtime compatibility with JDK 8 • for Spring apps built against JDK 6/7 but running against JDK 8

• when moving existing apps to a JDK 8 based deployment platform

Lambda Conventions in Spring APIs

§ JdbcTemplate • PreparedStatementSetter: void setValues(PreparedStatement ps) throws SQLException

• RowMapper: Object mapRow(ResultSet rs, int rowNum) throws SQLException

§ JmsTemplate • MessageCreator: Message createMessage(Session session) throws JMSException

§ TransactionTemplate + TransactionCallback, etc

Messaging, WebSocket, Async Processing

§ General org.springframework.messaging module • core message and channel abstractions

• endpoints using generic messaging patterns

§ WebSocket endpoint model along the lines of Spring MVC • JSR-356 and native server support, with SockJS fallback option

• STOMP for higher-level messaging on top of raw WebSocket

• https://spring.io/guides/gs/messaging-stomp-websocket/

§ AsyncRestTemplate • based on ListenableFuture return values

What is a Big Data application?§ Not just writing a few MR or Hive/Pig jobs. § Developing a comprehensive solution can be challenging § Key parts of the lifecycle involve • Ingestion • Stream Processing • Batch Workflow Orchestration • Export

§ Also requires • Enterprise Integration • Horizontally scalable deployments

§ How do you write one of these apps? • Status quo is to combine different projects together – not ideal
