Getting Started With Spring Integration

A new article has been published on InfoQ: Getting Started With Spring Integration. Enterprise Architect, Josh Long, describes the foundational concepts behind Enterprise Application Integration (EAI) and discusses the role played by ESBs and technologies like Spring Integration. The article provides a quick primer on using Spring Integration and gives a simple example that takes inbound emails to a known address and converts them into a blog entry.

Spring Framework 3.0 milestone released

The SpringSource Team announced that the Spring Framework 3.0 M1 is finally available for download!

This release features several major changes, including a start of the major 3.0 themes such as EL and REST support:

• revised project layout and build system with module-based sources
• updated entire codebase for Java 5 code style (generics, varargs)
• updated to JUnit 4.5 and JRuby 1.1
• introduced Spring EL parser (org.springframework.expression package)
• introduced support for #{…} expressions in bean definitions
• introduced expression-enabled @Value annotation for embedded expressions
• introduced @PathVariable annotation for URI template handling in MVC handlers
• introduced default value support for @RequestParam in MVC handlers
• introduced @RequestHeader annotation for HTTP header access in MVC handlers
• introduced AbstractAtomFeedView and AbstractRssFeedView base classes
• introduced <spring:url> and <spring:param> JSP tags

as well as various minor enhancements.

Note that Spring Framework 3.0 requires Java 5 or above and J2EE 1.4 or above. This framework is being build on Java 6 and Java EE 5 as the primary platform levels – but rest assured, the framwork will retain compatibility with Java 5 enabled J2EE 1.4 servers such as WebLogic 9 and WebSphere 6.1
