Spring WebApplicationInitializer 和 Jetty 8.x

Question

我正在尝试使用 Maven 在 Jetty 中部署应用程序:

我的插件配置如下:

<plugin>
  <groupId>org.mortbay.jetty</groupId>
  <artifactId>jetty-maven-plugin</artifactId>
  <version>8.0.4.v20111024</version>
</plugin>

我有一个 WebApplicationContextInitializer，我已将其简化为一个简单的形式:

AnnotationConfigWebApplicationContext dispatcherContext = new AnnotationConfigWebApplicationContext();

// Register and map the main dispatcher servlet
ServletRegistration.Dynamic dispatcher = container.addServlet("appServlet", new DispatcherServlet(dispatcherContext));
dispatcher.setLoadOnStartup(2);
dispatcher.addMapping("/site/*");

当我从 Spring Tool Suite 中运行 jetty:run 时，我无法访问我的 servlet。启动日志为:

如果然后导航到 http://localhost:8080/我得到默认的 Jetty 页面，没有列出任何上下文。

我已尝试将 webdefaults.xml 复制到我的项目中，如所述 here但这并没有解决问题。它只是删除了默认的 servlet 页面。

这可以在 Tomcat 中正确部署，因此我怀疑 maven-jetty-plugin 中存在问题。

有人有这方面的经验吗？

编辑:

所以我可以确认，如果我更改 Jetty 配置，以便将应用程序部署在 context/application 下，然后导航到 http://localhost:8080/application/site/我得到了 404。

但是，调度程序 servlet 已记录:

No mapping found for HTTP request with URI [/application/site/] in DispatcherServlet with name 'appServlet'

这表明我的 Controller 映射存在问题，是否正确？

启动日志显示此映射已注册:

Mapped "{[/],methods=[],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String org.test.application.controller.HomeController.catchAll()

我错过了什么？

新的 Jetty 插件似乎使用根“/”作为 Web 应用程序的根上下文，旧的插件如下所示:

contextPath Optional. The context path for your webapp. By default, this is set to the from the project's pom.xml. You can override it and set it to anything you like here.
