我一直在使用以下指南来开发 hello world REST Web 服务。
该指南可在以下位置找到：http
://wiki.eclipse.org/Creating_a_JAX-RS_Web_Service 我正在尝试打开路径：“ http://localhost:8080/BeezerServer/jaxrs/addresses ”


但它一直说“请求的资源（/BeezerServer/jaxrs/addresses）不可用。”

我的 web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-    app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee     http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
  <display-name>BeezerServer</display-name>
  <servlet>
    <description>JAX-RS Tools Generated - Do not modify</description>
    <servlet-name>JAX-RS Servlet</servlet-name>
    <servlet-class>org.apache.wink.server.internal.servlet.RestServlet</servlet-class>
    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>com.test.AddressBookApplication</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>JAX-RS Servlet</servlet-name>
    <url-pattern>/jaxrs/*</url-pattern>
  </servlet-mapping>
</web-app>

该项目如下所示（以防它可能对某人有所帮助）： 在此处输入图像描述
