如何使用Jetty提供JSP文件? [英] How to serve JSP files using Jetty?
问题描述
我正在嵌入码头，服务一个servlet和一些静态内容.我已经从 http://download.eclipse.org/jetty/下载了7.4.5.v20110725/dist/，并将JETTY_HOME/lib/*和JETTY_HOME/lib/jsp/*中的所有jar添加到eclipe中的用户库中；这些用户库已添加到我的项目中.如果我将JSP文件放在我的静态内容文件夹(./webapps/static/)中，并在 http中查看它://localhost:8080/static/test.jsp ，则不评估Java表达式，并显示文件的全部内容.
I'm embedding jetty, serving a single servlet and some static content. I've downloaded jetty from http://download.eclipse.org/jetty/7.4.5.v20110725/dist/, and added all jars from JETTY_HOME/lib/* and JETTY_HOME/lib/jsp/* to user librarys in eclipe; these user librarys have been added to my project. If I put a JSP file in my my static content folder (./webapps/static/) and view it at http://localhost:8080/static/test.jsp, the java expression are not evaluated and I get shown the full contents of the file.
我想念什么?
我的主要Java课:
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();
}
}
我要提供的JSP文件:
My JSP file I want to serve:
<html>
<body>
Time: <%= new java.util.Date() %>
</body>
</html>

更新:@JJ的建议有助于确定如何正确使用码头服务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.目前，我最基本的解决方法是将index.html或index.jsp放在./webapps/jsp/中，但我希望能够配置jetty返回一个禁止的错误.
Update: The suggestion from @JJ helped work out how to correctly serve JSP file with jetty. My only issue now is how to stop jetty from listing the directory contents of ./webapps/jsp/. The most basic fix I have for the moment is to put index.html or index.jsp in ./webapps/jsp/, but I would prefer be able to configure jetty to return a forbidden error.

webAppContext.setResourceBase("./webapps/jsp/");
// ??? THIS DOES NOT STOP DIR LISTING OF ./webapps/jsp/ ???
webAppContext.setInitParameter("dirAllowed", "false");
// 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, jsp and servlet context handlers.

// Add the handlers to the server and start jetty.
server.setHandler(handlers);

推荐答案
我认为您缺少一些关键内容，这些内容告诉Jetty将提供的文件解析为JSP内容而不是简单的静态文件.在无法调试代码的情况下，我无法确切看到丢失的内容，但是我建议您检查一下有关嵌入Jetty的参考:
I think you are missing some key piece which tells Jetty to parse the served files as JSP content instead of simply a static file. I can't see exactly what you're missing without being able to debug your code however I recommend you check this reference about embedding Jetty:
http://docs.codehaus.org/display/JETTY/Embedding+Jetty
我特别认为这段代码可能与您的问题有关:
In particular I think this piece of code may be relevant to your issue:
// assumes that this directory contains .html and .jsp files
// This is just a directory within your source tree, and can be exported as part of your normal .jar
final String WEBAPPDIR = "com/xxx/yyy/webapp";
final Server server = new Server(httpServerPort);
final String CONTEXTPATH = "/admin";
// for localhost:port/admin/index.html and whatever else is in the webapp directory
final URL warUrl = this.class.getClassLoader().getResource(WEBAPPDIR);
final String warUrlString = warUrl.toExternalForm();
server.setHandler(new WebAppContext(warUrlString, CONTEXTPATH));
