SpringOne2GX – Day 1 Keynote

Brain dump of the SpringOne2GX day 1 keynote featuring Rod Johnson, Graeme Rocher, and others.

Major tenets of SpringSource
- simplification
- community
- innovation
simplification
- amount of code in Spring apps has decreased over time as the amount of code in Spring itself has increased
- framework does more so you do less
- nice chart showing number of lines of code in Spring sample apps over time
community
- large–Gartner estimates at about 3 million developers
- traits of community: passionate, highly skilled, think for themselves
- get involved!
  - ask/answer questions on mailing list and forums
  - submit features and bugs to JIRA
  - participate in events (UGs, meetups, etc.)
  - start a UG or meetup in your area if there isn’t one
  - contribute code
    - doesn’t necessarily have to be core code–extensions, tests, plugins, etc.
innovation
- everything can be improved
- always new challenges to overcome

Spring 3.0

simplify configuration
MVC improvements
REST support built in
support for JSR-330 (DI via annotations)
Spring Integration — demo
- concept: “have Spring all the way down in your stack”

Groovy/Grails

all about productivity
integration all done for you
more prescriptive
- while Spring is about choice, that means more configuration
- Grails takes away some choice, but the trade-off is increased productivity
Groovy/Grails state of the nation
- huge growth in recent months–150% increase in traffic to web sites
- Groovy 1.7 and Grails 1.2 released coming soon
- big performance improvements in Grails 1.2
- plugin ecosystem very healthy
  - 25 million lines of user contributed code in 300+ plugins
  - cool stuff going on with alternative persistence mechanisms (e.g. CouchDB), RIAs, etc.
  - iPhone ads: “there’s an app for that” — Grails: “there’s a plugin for that”
- Challenges
  - IDE support–gets much better with newest SpringSource Tool Suite (STS)
  - hosting/cloud — need better support, easier deployment

Lifecycle and Tools

Build -> Run -> Deploy
tc Server developer edition — free download
- really nice dashboard with performance and health insight
Spring Insight Dashboard demo
- real-time performance graph
- huge amount of detail you can drill into by clicking on a request
- links back to STS–takes you right to the relevant spot in the code
- app health screen tracks performance by component over time
  - uses 99th percentile so you’re focused on what most users are experiencing
SpringSource Tool Suite
- Eclipse based
- single download for everything, including tc server

Keys to Future

developers
simplification
innovation
community
SpringSource + VMWare
- VMWare committed to community and open source
- VMWare serious about middleware
