我看到了很多关于它的话题，但没有一个是关于确切的场景，也没有一个是我的解决方案。

我有一个带有一些休息端点的简单网络应用程序。我用 Maven 的 Jersey 原型(prototype)配置了这个应用程序，到目前为止一切正常。今天我在项目中做了一个Maven更新项目，现在，当我从Eclipse启动Tomcat时，它没有找到org.glassfish.jersey.servlet.ServletContainer类。相信我，它工作得很好。

我试过删除 tomcat 的安装并重新配置它，但没有任何效果。我吓坏了!

这是 Tomcat 日志中的错误:

Jersey jar 像预期的那样位于 war 文件 lib 目录中:

jar file where org.glassfish.jersey.servlet.ServletContainer is

关于环境的一些事情:

我使用的是 Eclipse Luna、Maven 插件和安装，我使用的是 Tomcat 7。操作系统是 Linux Mint。

因此，据我所知，没有配置问题，因为正如我所说，它工作正常。 Jersey jar 在 war 文件中，而 Tomcat 根本看不到它。

有什么想法吗？

最好的问候

最佳答案

我在这里找到了解决方案:http://howtodoinjava.com/jersey/solved-java-lang-classnotfoundexception-org-glassfish-jersey-servlet-servletcontainer/

我只是不明白为什么即使使用 war 文件中的 Jersey jar 它也不起作用。

最好的问候!

关于Tomcat 不加载 Jersey org.glassfish.jersey.servlet.ServletContainer，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42014378/
