java - 服务器启动时出现 org.glassfish.jersey.servlet.ServletContainer ClassNotFoundException

Question

我正在尝试使用 Tomcat 和 Jersey 运行 REST 接口(interface)但没有成功，我在服务器启动时收到烦人的错误

Oct 13, 2014 2:53:45 PM org.apache.catalina.core.ApplicationContext log
INFO: Marking servlet Jersey Web Application as unavailable
Oct 13, 2014 2:53:45 PM org.apache.catalina.core.StandardContext loadOnStartup
SEVERE: Servlet  threw load() exception
java.lang.ClassNotFoundException: org.glassfish.jersey.servlet.ServletContainer
    at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1720)
    at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1571)
    at (...)

我正在使用:

1. OS X 10.8.5
2. IntelliJ IDEA 13.1.5
3. Tomcat 7.0.56
4. Java JDK 7 更新 67
5. maven 3.0.4
6. Jersey 2.13

我检查过类似的问题，但所有问题都通过更改 Jersey 版本解决了，但看起来我使用的是正确的。

知道我做错了什么吗？

好的，找到问题所在了。在我的例子中，我已将 lib 文件夹添加到 WEB-INF(项目结构-> Artifact ，然后在“可用元素”中选择所有这些文件夹，右键单击并选择“放入/WEB-INF/lib”)。
