Support Java-Based Application Configuration [SPR-7420]

[spring-projects-issues]

Chris Beams opened SPR-7420 and commented

Spring 3.0 introduced Java-Based bean definitions with @Configuration and @Bean.

This new feature for Spring 3.1 will introduce Java-based mechanisms for enabling the higher-level application configuration functionality currently found only in Spring's XML namespaces. These include but are not limited to:

• Enabling annotation-driven transaction management (<tx:annotation-driven/>)
• Enabling annotation-driven scheduling (<task:annotation-driven/>)
• Enabling AspectJ auto-proxying (<aop:aspectj-autoproxy)
• Enabling domain object DI with @Configurable (<aop:spring-configured/>)
• Enabling property-placeholder replacement (<context:property-placeholder/>)
• Enabling AspectJ load-time weaving (<context:load-time-weaver/>)
• Enabling MBean Export (<context:mbean-export/>)
• Enabling component scanning (<context:component-scan/>)
• Performing JNDI lookups (<jee:jndi-lookup/>)
• Looking up local and remote stateless session beans (<jee:local-slsb/>; <jee:remote-slsb/>)

This work is complete, coming largely in the form of Spring's new @Enable* annotations, such as @EnableTransactionManagement, @EnableScheduling, etc. Also includes the new @ComponentScan annotation, as well as the new LocalSessionFactoryBuilder in the orm.hibernate4 package which allows for convenient programmatic configuration of a Hibernate SessionFactory within @Bean methods without needing to deal with Spring's FactoryBean contract.

See Javadoc for each of these classes for complete details and code examples; reference documentation is pending at time of this resolution but will be complete for 3.1 GA.
