如何在Jetty上部署一个简单的JAX-RS应用程序？

标签： java rest servlets jax-rs

我正在尝试将简单的Web应用程序部署到jetty。

扩展javax.ws.rs.core.Application类的类如下：

package com.restfully.shop.services;

import javax.ws.rs.core.Application;
import java.util.HashSet;
import java.util.Set;

/**
 * Created by Administrator on 7/14/14.
 */
public class ShoppingApplication extends Application{

    private Set<Object> singletons = new HashSet<Object>();
    private Set<Class<?>> empty = new HashSet<Class<?>>();

    //Constructor
    public ShoppingApplication()
    {
        singletons.add(new CustomerResourceService());
    }

    @Override
    public Set<Class<?>> getClasses()
    {
        return empty;
    }

    @Override
    public Set<Object> getSingletons()
    {
        return singletons;
    }
}

我使用的web.xml文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
          http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         version="2.5">

    <servlet>
        <servlet-name>Rest</servlet-name>
        <servlet-class>com.restfully.shop.services.ShoppingApplication</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>Rest</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>

</web-app>

虽然我已经使用了RESTful Java和JAX-RS第一版，但我在IntelliJ Idea控制台上收到以下错误：

有什么想法吗？ 谢谢。

更新1：我甚至尝试使用JAX-RS-Unaware容器运行此Jax-Rs应用程序（请参阅下面的web.xml）

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
          http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         version="2.5">

    <servlet>
        <servlet-name>Rest</servlet-name>
        <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>javax.ws.rs.Application</param-name>
            <param-value>com.restfully.shop.services.ShoppingApplication</param-value>
        </init-param>
    </servlet>

    <servlet-mapping>
        <servlet-name>Rest</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>

</web-app>

但是我收到以下错误：

java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer

当然，我的pom.xml包含所有必需的文件。
