运行项目

========================

项目有了，进入项目的跟目录（即 \simple-service ）现在先测试运行下：

  1. $ mvn clean test

项目将会被编译，并且进行单元测试

上面可以看看到测试通过，下面我们用标准模式运行项目：

  1. $ mvn exec:java

运行结果如下：

  20. Jersey app started with WADL available at http://localhost:8080/myapp/applicatio
  21. n.wadl
  22. 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)：

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

curl

用-i命令获取所有回应的头文件信息：

  1. $ curl -i http://localhost:8080/myapp/myresource
  3. HTTP/1.1 200 OK
  4. Content-Type: text/plain
  5. Date: Sat, 30 Aug 2014 02:23:25 GMT
  6. Content-Length: 7
  8. 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：

  1. $ curl -v http://localhost:8080/myapp/myresource
  3. * Adding handle: conn: 0x5bc180
  4. * Adding handle: send: 0
  5. * Adding handle: recv: 0
  6. * Curl_addHandleToPipeline: length: 1
  7. * - Conn 0 (0x5bc180) send_pipe: 1, recv_pipe: 0
  8. * About to connect() to localhost port 8080 (#0)
  9. *   Trying 127.0.0.1...
  10. * Connected to localhost (127.0.0.1) port 8080 (#0)
  11. > GET /myapp/myresource HTTP/1.1

  16. < HTTP/1.1 200 OK
