通过。jar部署Jetty服务器。为什么我不能访问索引？

Question

public static void main(String[] args) {
    Server server = new Server(8080);

    ServletContextHandler servletContextHandler = new ServletContextHandler(NO_SESSIONS);
    servletContextHandler.setContextPath("/");

    DefaultServlet defaultServlet = new DefaultServlet();
    ServletHolder holderPwd = new ServletHolder("default", defaultServlet);

    final URL htmlDirectory = JerseyApplication.class.getResource("/html");

    holderPwd.setInitParameter("resourceBase", htmlDirectory.getFile());

    servletContextHandler.addServlet(holderPwd, "/*");
    server.setHandler(servletContextHandler);

    ServletHolder servletHolder = servletContextHandler.addServlet(ServletContainer.class, "/api/*");
    servletHolder.setInitOrder(0);
    servletHolder.setInitParameter(
            "jersey.config.server.provider.packages",
            "com.x.y.z.parser");

    try {
        LOGGER.info("Starting server");
        server.start();
        server.join();
    }
    catch (Exception ex) {
        LOGGER.error("Server failed to start - Aborting");
        ex.printStackTrace();
    }
    finally {
        LOGGER.info("Destroying server");
        server.destroy();
    }
}

当我运行jar tvf jarfile.jar grep html时，我可以看到html目录，它的内容就在其中：

0 Thu Nov 01 11:48:46 UTC 2018 html/
2258 Thu Nov 01 11:48:46 UTC 2018 html/formRequest.js
871 Thu Nov 01 11:48:46 UTC 2018 html/index.html

谢了！

使用从HtmlDirectory获得的URL作为整个ServletContexthHandler的基本资源。

详情见先前答复:https://stackoverflow.com/a/39019797/775715

final URL htmlDirectory = JerseyApplication.class.getResource("/html");

// TODO: Handle error if htmlDirectory == null

ServletContextHandler servletContextHandler = new ServletContextHandler(NO_SESSIONS);
servletContextHandler.setContextPath("/");
servletContextHandler.setBaseResource(Resource.newResource(htmlDirectory));

DefaultServlet defaultServlet = new DefaultServlet();
ServletHolder holderPwd = new ServletHolder("default", defaultServlet);
// holderPwd.setInitParameter("resourceBase", htmlDirectory.getFile()); <-- not needed here
servletContextHandler.addServlet(holderPwd, "/"); // NOTE: MUST be "/" not "/*"!

最后一件事，你好像在用泽西。（又名Jersey.config.server.provider.packages)确保禁用使Jersey本身服务静态内容的Jersey配置。让杰蒂负责。（至于如何做到这一点，这是另一个问题，这是Jersey版本特定的，在stackoverflow上已经有了答案）
