Dear Spring Community,

Spring 2.5.1 is the first bug fix and enhancement release in the Spring 2.5 series. It closes a couple of gaps found in Spring 2.5 final and introduces various new features in the context of Java 6 and Java EE 5 support:
  • Java-5-specific Model interface for use with MVC handler methods
  • @ModelAttribute's default attribute names are consistently derived from the *declared* parameter/return type
  • Support for last-modified handling in @RequestMapping handler methods (through the WebRequest interface)
  • SpringBeanAutowiringSupport class for self-autowiring classes within a web app (e.g. JAX-WS endpoints)
  • EJB3-compliant SpringBeanAutowiringInterceptor for processing Spring's @Autowired in EJB3 SBs/MDBs
  • Remoting support for the HTTP server that is included in Sun’s JDK 1.6 (covering HTTP invoker, Hessian and Burlap)
  • "jms:listener-container" tag supports a concurrency range (e.g. "3-5"), for specifying a minimum number of consumers
  • Tiles2 support works on JDK 1.4 as well
  • Any many further enhancements in the details…
