上面可以看看到测试通过，下面我们用标准模式运行项目：

$ mvn exec:java

运行结果如下：

Jersey app started with WADL available at http://localhost:8080/myapp/applicatio
n.wadl
Hit enter to stop it...

项目已经运行，项目的 WADL 描述存在于http://localhost:8080/myapp/application.wadl URI中,将该URI在控制台 以curl命令执行或者浏览器中运行，就能看到该 WADL 描述以 XML 格式展示。 WADL

更多 WADL的内容，请查考

Chapter 16, WADL Support 浏览器

接下来试下与部署在 /myresource 下面的资源的交互。将资源的URL输入浏览器，或者在控制台用curl命令执行(译者注：如果没有安装curl,请参考curl安装)：

$ curl http://localhost:8080/myapp/myresource
Got it!

curl

用-i命令获取所有回应的头文件信息：

$ curl -i http://localhost:8080/myapp/myresource

HTTP/1.1 200 OK
Content-Type: text/plain
Date: Sat, 30 Aug 2014 02:23:25 GMT
Content-Length: 7

Got it!

注意到Content-Type: text/plain是在 MyResource 类中用@Produces 注解的。

如果想看到更多返回信息，可以变换不同的 curl 命令参数。举例：

$ curl -v http://localhost:8080/myapp/myresource

* Adding handle: send: 0
* Adding handle: recv: 0
* Curl_addHandleToPipeline: length: 1
