提问by user3531270
I've been a .NET web developer for several years now, working with asp.net web forms and c#, wcf etc.But recently developed touch enabled customer facing application. Its device-agnostic application designed for any platform capable of running HTML5 applications (iOS, Android, Windows8), for Mobile devices (such as tablets), Assisted or unassisted kiosks, Laptop or desktop computers.
几年来，我一直是 .NET web 开发人员，使用 asp.net web 表单和 c#、wcf 等。但最近开发了面向客户的触摸应用程序。其与设备无关的应用程序专为能够运行 HTML5 应用程序（iOS、Android、Windows8）的任何平台、移动设备（如平板电脑）、辅助或非辅助信息亭、笔记本电脑或台式计算机而设计。

Jersey (jax-rs)is a very solid alternative to ASP.NET Web API in the Java World.
Jersey (jax-rs)是 Java 世界中 ASP.NET Web API 的非常可靠的替代品。
Jersey RESTful Web Services framework is open source, production quality, framework for developing RESTful Web Services in Java...
Jersey RESTful Web 服务框架是开源的、生产质量的、用于在 Java 中开发 RESTful Web 服务的框架...
It's an annotation based approach to the problem. I think it's a very well thought and productive environment. You can customize all sorts of stuff and that contains sane defaults.
这是一种基于注释的方法来解决问题。我认为这是一个经过深思熟虑和富有成效的环境。您可以自定义各种包含合理默认值的内容。

@RestController
public class GreetingController {
private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();
@RequestMapping("/greeting")
public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) {
return new Greeting(counter.incrementAndGet(),
String.format(template, name));
