JAXB 对待泛型还是有些问题的， 建议你使用extension 而不是泛型来定义你的更

Hello Willem:

   谢谢你的回复！我明白你说的意思，但是如何用extension来做我有些不明白？
   对我来讲，CXF的JSon对象序列化机制实在是有些死板。我很想替换掉他的序列化机制，改用我自己的Interceptor来手工序列化对象。这样我可以不用写固定的annotation或者用复杂的data binding tools来做，请问你再这方面有什么建议么？
   我看到cxf-user forum里的Sergey 谈到WADL的support，我相信如果基于CXF-RS-*的开发，在以后也会转到用WADL来定义和构建。如果我想以后迁移到标准的开发方式来，现在是否依然需要保持CXF的原有序列化组件呢？
   我同样发了个详细的帖子在cxf-user forum里面，包括详细的代码和实现。Link：
http://www.nabble.com/Exception-about-%22***-nor-any-of-its-super-class-is-known-to-this-context%22-td25004234.html
   
   Thanks!

OH, 我试着看了下他的序列化实现。这个JAXRSOutInterceptor里面做的事情很多，我想简单用对象序列化的方法需要更多的代码实现，所以我放弃了。

原来的代码我试着用继承的方式来搞，虽然这样会产生很多的代码类在case by case情况下。但也想不到有更好的方法了：（

JAXB 的功能还是很强大的， 只要你定义好数据模型 ，case by case的工作很少的。

[Sam.Wang]

Hi Willem:

真的很感谢你的回复！我目前有些这方面的research对于CXF-RS的应用，你能提供些实际经验给我么？谢谢！

项目的一些介绍：主要是based在CXF-RS服务实现上的。前台view layer使用静态富客户端（Extjs）来实现的，通过Ajax进行RS的访问，中间层采用JSON作为数据载体，整体用RESTful风格来实现和进行调用。业务层面上很简单，主要是实现一个配置管理的系统。没有过多的业务流程和操作，大部分的cases是进行CRUD的操作。

Thanks！
Sam

[Sam.Wang]

Hello Willem:

首先谢谢你的帮助，对于JAXB序列化确实有些困难和小问题。不过Sergey提供了一个小方案，来完美的支持泛型的序列化。我相信也有很多人如果用泛型的话会遇到类似的问题，请不妨参考这个帖子的讨论和解决方案。

http://www.nabble.com/Exception-about-%22***-nor-any-of-its-super-class-is-known-to-this-context%22-td25004234.html

Thanks
Sam.

JAXB 对待泛型还是有些问题的， 建议你使用extension 而不是泛型来定义你的更
新接口。
