更新 jetty servlet 9.2.2 到 9.3.8

Question

我正在尝试将 jetty 服务器和 servlet 从版本 9.2.2 更新到版本 9.3.8 更新我的 pom.xml 文件后，出现一些错误，例如找不到 ServletContextHandler 和 ServletHolder！

这是我的 pom.xml

<dependency>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-server</artifactId>
            <version>9.3.8.v20160314</version>
    </dependency>

    <dependency>
        <groupId>org.eclipse.jetty</groupId>
        <artifactId>jetty-servlets</artifactId>
        <version>9.3.8.v20160314</version>
    </dependency>

这是我的 JettyServer class

public static void start() throws Exception
{
    Server server = new Server(Configuration.getInstance().getPortServer());

    ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
    context.setContextPath("/");

    ServletHolder h = new ServletHolder(new HttpServletDispatcher());
    h.setInitParameter("javax.ws.rs.Application", "de.jettyserver.Services");
    context.addServlet(h, "/*");

    server.setHandler(context);

    server.start();
    server.join();

    LOGGER.debug("JettyServer started");
}

和错误

你的依赖有错别字。

<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-servlet</artifactId> <!-- not plural! -->
    <version>9.3.8.v20160314</version>
</dependency>
