我正在尝试使用提供一些动态数据的自定义servlet和提供一些图像的默认servlet创建一个嵌入式码头服务器。我有自定义的servlet,但是我不知道如何添加默认的servlet来提供图像文件。
这就是我所拥有的…
private void setUpServer(ServerOptions options){ s = new Server(options.getPort()); this.options = options; context = new ServletContextHandler(ServletContextHandler.SESSIONS); context.setContextPath("/"); s.setHandler(context); context.addServlet(new ServletHolder(new DataServlet()), "/data/*"); context.addServlet(new ServletHolder(new DefaultServlet()), "/pictures/*"); }
我无法弄清楚如何将DefaultServlet配置为用作文件服务器,并且仍然使自定义DataServelet仍然有效。
有人有什么想法吗?
你需要什么:
ServletHolder.setInitParameter(name,value)
AltDefaultServlet.java
package jetty.demo; import org.eclipse.jetty.server.Server; import org.eclipse.jetty.server.ServerConnector; import org.eclipse.jetty.servlet.DefaultServlet; import org.eclipse.jetty.servlet.ServletContextHandler; import org.eclipse.jetty.servlet.ServletHolder; public class AltDefaultServlet { public static void main(String[] args) { System.setProperty("org.eclipse.jetty.LEVEL","INFO"); Server server = new Server(); ServerConnector connector = new ServerConnector(server); connector.setPort(8080); server.addConnector(connector); // The filesystem paths we will map String homePath = System.getProperty("user.home"); String pwdPath = System.getProperty("user.dir"); // Setup the basic application "context" for this application at "/" // This is also known as the handler tree (in jetty speak) ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS); context.setBaseResource(Resource.newResource(pwdPath)); context.setContextPath("/"); server.setHandler(context); // add a simple Servlet at "/dynamic/*" ServletHolder holderDynamic = new ServletHolder("dynamic", DynamicServlet.class); context.addServlet(holderDynamic, "/dynamic/*"); // add special pathspec of "/home/" content mapped to the homePath ServletHolder holderHome = new ServletHolder("static-home", DefaultServlet.class); holderHome.setInitParameter("resourceBase",homePath); holderHome.setInitParameter("dirAllowed","true"); holderHome.setInitParameter("pathInfoOnly","true"); context.addServlet(holderHome,"/home/*"); // Lastly, the default servlet for root content (always needed, to satisfy servlet spec) // It is important that this is last. ServletHolder holderPwd = new ServletHolder("default", DefaultServlet.class); holderPwd.setInitParameter("dirAllowed","true"); context.addServlet(holderPwd,"/"); try { server.start(); server.dump(System.err); server.join(); } catch (Throwable t) { t.printStackTrace(System.err); } } }
