Jetty、Jersey 和 Maven - Spring 错误

Question

所以我最近开始使用 maven 来管理依赖项，并开始尝试使用 Jersey 来构建 REST API。我遇到了一个很棒的教程here。 here 发布了一个类似的 StackOverFlow 问题，第一个接受的响应具有相同的 maven 脚本。

我要部署到的服务器是 Jetty，所以我安装了 Jetty 的 eclipse 插件（Eclipse Jetty 3.8.0，它使用 Jetty-9.2.5 ) 并且过去仅将其用于 servlet 没有问题。当我修改 pom.xml 文件时，我会执行 Maven - Clean 和 Maven - Install，并且所有 似乎 都将在类中适当列出启动时显示的路径。

所以我不太清楚为什么它看不到那个 SpringServlet。此外，为什么在上面提供的链接中，他们主要使用 Jetty 时会引用 GlassFish 模块？

您只是缺少正确的工件。

您的项目中根本不存在对 servlet com.sun.jersey.spi.spring.container.servlet.SpringServlet 的引用。

快速搜索com.sun.jersey.spi.spring.container.servlet.SpringServlet on search.maven.org 会显示包含该类的工件。

您可能缺少依赖项，或者您不应该使用该特定 servlet 进行设置。由你决定你想去哪条路。
