Я создаю простой проект Spring MVC. Когда я запускаю его на Tomcat, все работает правильно, но я хотел бы использовать Maven Jetty Plugin для его запуска. Ниже картина структуры проекта:
Мой файл pom.xml выглядит так:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Файл HomeController.java:
@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";
}
}

Я думаю, что я сделал какую-то ошибку в конфигурации Jetty в pom.xml, и Jetty не видит контекст. Обычно сервер запущен, ошибок нет. Когда я смотрю на вывод консоли, есть:
web.xml file = null
Некоторая проблема с настройкой Jetty в pom.xml. Спасибо.
