This release completes the key Spring 3.0 feature set. Beginning with the original themes REST and EL the feature list have been expanded significantly:
- Fully Java 5 based
- Spring expression language (SpEL)
- Extended support for annotation-based components
- Powerful stereotype model
- Standardized dependency injection annotations
- Declarative model validation based on constraint annotations
- Enhanced binding and formatting facilities
- Comprehensive REST support
- Object/XML Mapping (OXM)
- Portlet 2.0 support
- Next-generation scheduling capabilities
- Early support for Java EE 6
More words on the JEE6 support. Spring 3.0 already supports the use of JSF 2.0 and JPA 2.0 in a Spring environment, in addition to JSR-303 and JSR-330 support. Further Java EE 6 related specifications such as Servlet 3.0 will be fully supported as they become available in concrete products; this is scheduled for the Spring 3.1/3.2 timeframe.
