本文对比了传统MVC控制器与RESTful Web服务控制器在HTTP响应体创建方式上的区别。RESTful服务通过直接返回对象的方式简化了流程，该对象的数据将作为JSON格式直接写入HTTP响应中。

The above example does not specify GET vs. PUT, POST, and so forth, because @RequestMapping maps all HTTP operations by default. Use @RequestMapping(method=GET) to narrow this mapping.

2.返回结果的不同

A key difference between a traditional MVC controller and the RESTful web service controller above is the way that the HTTP response body is created. Rather than relying on a view technology to perform server-side rendering of the greeting data to HTML, this RESTful web service controller simply populates and returns a Greeting object. The object data will be written directly to the HTTP response as JSON.
