是否可以将EJB项目公开为RESTful WS？(Is it possible to expose an EJB project as a RESTful WS?)

是否可以将EJB项目公开为RESTful WS？(Is it possible to expose an EJB project as a RESTful WS?)

我使用jersey实现了RESTful Web服务并将其部署在Tomcat上，我使用DAO类来操作数据库操作，实体包装数据库记录。 并在单独的包中进行处理。 我想使用EJB分发这个系统。 首先，做这个改变会很容易。 或者我需要从头开始重写。 其次，我仍然需要拥有REST WS，那么是否可以将EJB公开为REST WS以及如何？ REST WS是在同一个EJB项目中还是在另一个项目中？

I have implemented a RESTful web service using jersey and deployed it on Tomcat, I have used DAO classes to manipulate database operations, entities to wrap database records. and did the processing in separate package. I want to make this system distributed using EJB. First of all would it be easy to do this change. or i need to rewrite things from scratch. Second, I still need to have the REST WS, so would it be possible to expose the EJB as a REST WS and how? would the REST WS be in the same EJB project or in a different one?

您绝对可以将其作为EJB和REST WS来实现。 将Tomcat安装升级到TomEE Plus ，然后将@Stateless或@Singleton添加到现有REST服务。

由于Java EE版本的Tomcat（TomEE）包含用于JAX-RS支持的CXF，因此您不再需要Jersey。

此示例没有详细记录，但显示了一个结合了EJB和JAX-RS的功能应用程序。

You can definitely do it as an EJB and REST WS. Upgrade your Tomcat install to TomEE Plus, then just add @Stateless or @Singleton to the existing REST service.

You won't need Jersey in there anymore as the Java EE version of Tomcat (TomEE) includes CXF for JAX-RS support.

This example is not well documented, but shows a functional application that combines both EJB and JAX-RS.
