Question

我有https://stackoverflow.com/a/28735121/5030226的代码。它服务于目录但是当我打开一个html文件。它会引发内部服务器错误。 请帮忙..

     Server server = new Server(8080);
     ServletContextHandler context = new 
     ServletContextHandler(ServletContextHandler.SESSIONS);

    context.setContextPath("/");

    DefaultServlet defaultServlet = new DefaultServlet();
    ServletHolder holderPwd = new ServletHolder("default", defaultServlet);
    holderPwd.setInitParameter("resourceBase", "./src/webapp/");

    context.addServlet(holderPwd, "/*"); 

    server.setHandler(context);

    server.start();
