POJO Aspects in Spring 2.0: A Simple Example

While the material in this post is quite simple, it will actually offer a glimpse of some rather significant new features in Spring 2.0. I hope that with a little imagination, you will be able to apply what you see here to far less trivial use cases of your own.

I am going to show 2 examples actually. The first will use a rather simple logger:


package example; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; public class SimpleLogger { private static Log log = LogFactory.getLog(SimpleLogger.class); public void logOneString(String s) { log.info("string=" + s); } public void logTwoStrings(String s1, String s2) { log.info("string1=" + s1 + ",string2=" + s2); } }

Inaugural Sydney Spring User Group Meeting

Over 200 people registered to attend the inaugural Sydney Spring User Group meeting, which was held on 22 February 2006. As shown by the photos (below), there was standing room only, and several attendees flew in from interstate for the evening.

With one-third of those attending indicating they do not presently use Spring, Rod Johnson's “Introduction to Spring” presentation was well-received and motivated many questions. The planned “Spring 2.0 and Beyond” talk – which undoubtedly will be of keen interest to those who are currently using Spring – was rescheduled until the next meeting.
