如何在pom.xml中的Maven Jetty Plugin中设置web.xml的路径？

Question

我创建了一个简单的Spring MVC项目。当我在Tomcat上运行它时，一切正常，但我想使用Maven Jetty插件来运行它。下面是项目结构图：

我的pom.xml文件如下所示：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        </plugins>
        <finalName>${project.artifactId}</finalName> <!-- added to remove Version from WAR file -->
    </build>
</project>

我的web.xml文件如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

    <!-- Add Spring MVC DispatcherServlet as front controller -->
    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>
                org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/spring-servlet.xml</param-value>

    </servlet>

    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

 </web-app>

HomeController.java文件：

@Controller
public class HomeController {

    /**
     * Simply selects the home view to render by returning its name.
     */
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String home(Locale locale, Model model) {
        System.out.println("Home Page Requested, locale = " + locale);
        Date date = new Date();
        DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);

        String formattedDate = dateFormat.format(date);

        model.addAttribute("serverTime", formattedDate);

        return "home";
    }

    @RequestMapping(value = "/user", method = RequestMethod.POST)
    public String user(@Validated User user, Model model) {
        System.out.println("User Page Requested");
        model.addAttribute("userName", user.getUserName());
        return "user";
    }
}

控制台的输出：

我认为我在pom.xml中配置Jetty时犯了一些错误，而Jetty没有看到上下文。一般服务器已经启动，没有错误。当我查看控制台的输出时，有：

web.xml file = null

pom.xml中Jetty配置的一些问题。谢谢。

如果您可以更改项目结构，从/WebContent/重命名为/src/main/webapp/，那么它将适用于所有Maven提供的webapp服务（jetty，tomcat，jboss，glassfish等），包括所有Intellij和Eclipse IDE webapp服务。
