在Eclipse中运行简单的jersey程序时，tomcat 8.0无法启动

Question

我对这个问题感到沮丧。 尝试了Internet上所有可能的解决方案，但仍然没有运气。

当我运行此代码时，tomcat每次都无法启动并失败。 请帮忙

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<!-- This web.xml file is not required when using Servlet 3.0 container, 
     see implementation details http://jersey.java.net/nonav/documentation/latest/jax-rs.html#d4e194 -->

<web-app version="2.5" 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">
    <servlet>
        <servlet-name>Jersey Web Application</servlet-name>
        <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>com.sun.jersey.config.property.packages</param-name>
            <param-value>com.restapp.jerseyapp</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Jersey Web Application</servlet-name>
        <url-pattern>/jersey/*</url-pattern>
    </servlet-mapping>
</web-app>

码：

package com.restapp.jerseyapp;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

/** Example resource class hosted at the URI path "/myresource"
 */
@Path("/hi")
public class MyResource {

    /** Method processing HTTP GET requests, producing "text/plain" MIME media
     * type.
     * @return String that will be send back as a response of type "text/plain".
     */
    @GET 
    @Produces("text/plain")
    public String getIt() {
        return "Hi there!";
    }
}

控制台输出

INFO: Starting Servlet Engine: Apache Tomcat/8.0.47

我也有同样的问题。 我通过从本地Maven存储库中删除球衣罐，然后重新安装了相同的罐来解决此问题。

C:\Users\{user}\.m2\repository\com\sun\jersey

完成上述步骤后，请执行maven install。
