Vaadin 7/8和嵌入式Jetty

我想使用嵌入式jetty(eclipse luna内置版本)部署vaadin(版本7.2.5)Web应用程序。

目前,我的代码如下:

public class Launcher {
    private static int httpPort = 8080;

    public static void main(String[] args) throws Exception
    {
        Server server = new Server();
        SocketConnector connector = new SocketConnector();
        connector.setMaxIdleTime(1000 * 60 * 10);
        connector.setSoLingerTime(-1);
        connector.setPort(httpPort);
        connector.setReuseAddress(false);
        QueuedThreadPool pool = new QueuedThreadPool();
        pool.setMinThreads(10);
        pool.setMaxThreads(100);
        server.setConnectors(new Connector[] { connector });
        server.setThreadPool(pool);
        WebAppContext context = new WebAppContext();
        context.setServer(server);
        context.setContextPath("/");
        context.setWar("ReportWriter.war");
        context.setClassLoader(Thread.currentThread().getContextClassLoader());
        server.setHandler(context);
        try
        {
            server.start();
        } catch (Exception e) {
               e.printStackTrace();
        }
    }
}

我是从vaadin forum thread复制的。服务器似乎启动,WAR实际上被解压缩。

将我的浏览器指向http://localhost:8080/,而不是启动我的vaadin(版本7.2.5)应用,我看到的只是:

localhost:8080

以防它可能很重要:我在eclipse中的WAR项目的目录树:

看起来你在某种程度上错过了将/ *映射到Vaadin Web应用程序所需的servlet配置。似乎有适当的web.xml应该处理,但检查内容是否指向正确的Servlet / UI类和URI。

除了在web.xml中进行映射之外,您可以在UI类中使用@WebServlet带注释的servlet(使用JSR 315时):

@WebServlet(value = "/*", asyncSupported = true)
@VaadinServletConfiguration(productionMode = false, ui = MyDemoUI.class)
public static class Servlet extends VaadinServlet {
}

此外,上面的WAR结构看起来很可疑(尽管浏览器屏幕截图中的目录列表看起来不错)。确保类位于/WEB-INF/classes/下,以便对servlet容器可见。还有/ WEB-INF下的web.xml。
