Tomcat Jersey Eclipse ClassNotFound org.glassfish.jersey.servlet.ServletContainer

我正在运行你好世界 http://www.mkyong.com/webservices/jax-rs/jersey-hello-world-example/例子。

不过我用的是2.7版本。

在 maven pom.xml 我有

我尝试从命令行和 Eclipse 上的服务器插件中运行 servlet。我犯了同样的错误：

奇怪的是我可以在 .jar 文件中看到该类。班级就在那里。

我什至尝试添加 jar 跳过 maven，但 Tomcat 不会看到该类。

Eclipse + tomcat - 部署时出现 ClassNotFound 异常 https://stackoverflow.com/questions/12712224/eclipse-tomcat-classnotfound-exception-on-deploy

如果您已安装 Maven Eclipse 插件和 Maven WTP 插件，则这是自动的。如果您没有安装这些，请继续安装它们，然后一旦 Eclipse 重新启动，右键单击该项目并执行 Maven > 更新项目...这将在内部更改项目配置，以便将 Maven 依赖项复制到部署目标上的 /WEB-INF/lib 文件夹。

如果您不想使用任何这些插件，则必须转到项目属性 > 部署程序集配置并手动添加依赖项，但同样，这是由这些插件自动完成的。
