一个Java的Restful服务框架，支持JPA、JAAS、分布式资源对象

1. 也不支持Accept-Launguage，这个功能可以在模板中通过多语言标签来实现。
2. 支持手工处理缓存这个可以实现。

1. 将rest从核心应用中分离了出来 (重构)
2. 增加了Struts2的插件，可以脱离JRest4Guice，在struts2中使用除了rest功能之外的所有功能（jpa、事务、权限、拦截器等）（新增)
3. 优化了事务的声明，允许声明在类上，不用在每个方法都去声明 (增强)
4. 增加了对自定义拦截器的支持（新增)
5. 优化了BaseEntityManager的注入方式，不再需要通过init方式来由用户构造 (增强)
6. 增强了对View部分处理，根据模板的扩展名自动选择渲染引擎，并增加了重定向的支持 (增强)
7. 支持Hibernate validator（新增)
8. 完善了demo，增加了非AJAX环境下的使用案例（新增)

@Transactional//事务支持，缺省为TransactionalType.REQUIRED，可以在方法中覆写

})

		return this.entityManager.pageByNamedQuery("list",
				new Pagination(pageIndex, pageSize));
