Tomcat 7 ClassNotFoundException：org.glassfish.jersey.servlet.ServletContainer

Question

我试图在OS X 10.10上运行apache 7.0.57的RESTful服务，使用Jersey 2.13和JDK 8。我已经部署了apache，它开始正常。我编写了一个简单的RESTfull服务，并将其部署到WEB-INF/类。网络。已配置xml。但是，当我尝试启动tomcat时，restful资源错误如下

SEVERE: Servlet /resttest threw load() exception

java 类

package org.sample.resources;

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

@Path("/xyz")
public class TestGet {

  @GET
  @Produces(MediaType.TEXT_PLAIN)
  public String sayHello() {
      return "Hello Jersey";
  }
}

我甚至已经将 jersey-container-servlet-core 的内容提取.jar到 WEB-INF/classes 目录中，但在重新启动时，我仍然收到相同的错误。

有什么建议吗？

在资源管理器中，手动将所有泽西罐文件复制到WEB-INF / lib;当我遇到同样的问题时，我这样做了，这对我有用。
