Jetty、Jersey 和 Maven - Spring 错误

Question

所以我最近开始使用maven来管理依赖关系，并开始尝试使用Jersey来构建REST API。我发现了一个很棒的教程 here. A similar Whosebug question was posted here，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，所以我已经为 Jetty 安装了 eclipse 插件（Eclipse Jetty 3.8.0 使用 Jetty- 9.2.5) 并且过去仅将其用于 servlet 时没有遇到任何问题。当我修改 pom.xml 文件时，我执行了 Maven - Clean & Maven - Install ，所有内容 都出现了 将在启动时显示的 class 路径中适当列出。

所以我不太确定为什么它看不到那个 SpringServlet。此外，为什么在上面提供的链接中，它们主要使用 Jetty 时却引用 GlassFish 模块？

Answer 1

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 class 的工件。

您可能缺少依赖项，或者您不应该为您的设置使用那个特定的 servlet。想走哪条路，由您决定。
