我嵌入了 jetty,提供单个 servlet 和一些静态内容。我从下载了码头http://download.eclipse.org/jetty/7.4.5.v20110725/dist/ http://download.eclipse.org/jetty/7.4.5.v20110725/dist/,并将 JETTY_HOME/lib/* 和 JETTY_HOME/lib/jsp/* 中的所有 jar 添加到 eclipe 中的用户库;这些用户库已添加到我的项目中。如果我将 JSP 文件放入静态内容文件夹 (./webapps/static/) 并在以下位置查看它http://localhost:8080/static/test.jsp http://localhost:8080/static/test.jsp,java 表达式不会被求值,我会看到文件的完整内容。
我缺少什么?
我的主要java类:
import org.eclipse.jetty.server.Handler;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.handler.ContextHandler;
import org.eclipse.jetty.server.handler.HandlerList;
import org.eclipse.jetty.server.handler.ResourceHandler;
import org.eclipse.jetty.server.nio.SelectChannelConnector;
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.servlet.ServletHolder;
public class Test {
public static void main(String[] args) throws Exception {
Server server = new Server();
SelectChannelConnector connector = new SelectChannelConnector();
connector.setPort(8080);
server.addConnector(connector);
// Create a resource handler for static content.
ResourceHandler staticResourceHandler = new ResourceHandler();
staticResourceHandler.setResourceBase("./webapps/static/");
staticResourceHandler.setDirectoriesListed(true);
//staticResourceHandler.setWelcomeFiles(new String[]{ "index.html", });
//staticResourceHandler.setCacheControl("no-store,no-cache,must-revalidate");
// Create context handler for static resource handler.
ContextHandler staticContextHandler = new ContextHandler();
staticContextHandler.setContextPath("/static");
staticContextHandler.setHandler(staticResourceHandler);
// Create servlet context handler for main servlet.
ServletContextHandler servletContextHandler = new ServletContextHandler(ServletContextHandler.SESSIONS);
servletContextHandler.setContextPath("/");
servletContextHandler.addServlet(new ServletHolder(new HelloServlet()),"/");
// Create a handler list to store our static and servlet context handlers.
HandlerList handlers = new HandlerList();
handlers.setHandlers(new Handler[] { staticContextHandler, servletContextHandler });
// Add the handlers to the server and start jetty.
server.setHandler(handlers);
server.start();
server.join();
}
}
我想要提供的 JSP 文件:
<html>
<body>
Time: <%= new java.util.Date() %>
</body>
</html>

更新:@JJ 的建议帮助解决了如何使用 jetty 正确提供 JSP 文件。我现在唯一的问题是如何阻止 jetty 列出 ./webapps/jsp/ 的目录内容。我目前最基本的修复是将index.html或index.jsp放入./webapps/jsp/中,但我更希望能够配置jetty以返回禁止的错误。
