我一直在开发由 jetty 提供的 Java .war Web 应用程序。我正在集成 Shiro 以进行用户身份验证/授权。一切都很顺利，直到需要将 MySql 服务器连接到 Jdbc 领域。第一次添加 jetty-web.xml 后，我的嵌入式码头服务器遇到了很多问题。有关 WebAppContext 与 WebAppContext 不是同一类的投诉。

我只是删除了码头和所有对它的引用来解决我的班级错过匹配问题。我的 webapp 现在加载，MySql 支持甚至可以工作，但我收到了大量警告。看起来他们来自码头的某个地方，我不确定如何追查这个问题。任何帮助弄清楚这是从哪里来的，我们将不胜感激。这是我收到的警告示例。下面的代码片段。

我今天在使用 maven jetty 插件时遇到了同样的问题，版本：8.1.10.v20130312，并且使用 maven pom.xml 将 apache-cxf 2.7.13 包含到我的类路径中。当删除库 cxf-rt-transports-http-jetty 时，它解决了这个问题。这个库使用一些码头类，我想它依赖于不同版本的码头，正如史蒂文在评论中所说，它与类加载器有关（一个用于 WEB-INF\lib 和一个用于服务器）。这是我为解决我的问题而删除的 Maven 依赖项：

<dependency>
   <groupId>org.apache.cxf</groupId>
   <artifactId>cxf-rt-transports-http-jetty</artifactId>
   <version>2.7.13</version>
</dependency>

所以这取决于你的类路径。它可能包含另一个码头版本。
