Java 为什么我的简单springmvc web应用程序会关闭Jetty？

查看我的一个简单的springmvc应用程序的日志文件，homecontroller索引操作输出“hello world”，该站点似乎因为某种原因关闭了

我只是将.war文件推送到jetty_home/webapps文件夹，然后启动jetty服务

这是一个IntelliJ.war文件，它是使用maven项目构建的

这是我的第一次部署，所以请不要以为我知道我在做什么：

更新

实际上，当我运行wget localhost:8080/springmvc/I时，我会得到以下消息：

Resolving localhost... 127.0.0.1

由于某些原因，这在jetty上不起作用，在tomcat上效果很好？

如果这是一个maven项目，请将yetty插件添加到pom文件中

<plugins>
  <plugin>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>maven-jetty-plugin</artifactId>
        <version>6.1.10</version>
  </plugin>
</plugins>

据

Jetty不直接实现JSP。相反，它使用servlet来提供servle规范所需的功能。[…]2.5servlet规范的配套规范是2.1JSP规范

因此，您需要一个带有JSP的jar

如果您在maven插件中使用Jetty 6，我想Peter Szanto回答的依赖关系将解决这个问题。另一方面，如果将其作为应用程序的一部分使用，则需要添加适当的jsp jar

例如，对于使用Jetty 6.1的Maven项目，可以在pom.xml中包括：

在web上搜索jetty和jsp支持；这是一个已知的配置/库问题，事实上在一两天前回答了一个SO问题；这是一个已知的配置/库问题，实际上在一两天前回答了一个SO问题。
