[英]Jetty Servlet context not found
I am running Jetty with 2 handlers, webapp and servlet, and 2 contexts, "/" and "/d/*". 我正在使用2个处理程序(webapp和servlet)以及2个上下文“ /”和“ / d / *”运行Jetty。
Webapp loads fine, while I get "404 Not found" when trying to go to servlet. Webapp加载正常,而尝试转到servlet时显示“ 404 Not found”。
Here is the code I use: 这是我使用的代码:
public static void main(String[] args){
// The simple Jetty config here will serve static content from the webapp directory
String webappDirLocation = "src/main/webapp/";
// The port that we should run on can be set into an environment variable
// Look for that variable and default to 8080 if it isn't there.
String webPort = System.getenv("PORT");
if (webPort == null || webPort.isEmpty()) {
webPort = "7777";
}
Server server = new Server(Integer.valueOf(webPort));
HandlerCollection handlerCollection = new HandlerCollection();
// Add the GUI part
WebAppContext webapp = new WebAppContext();
webapp.setContextPath("/");
webapp.setDescriptor(webappDirLocation + "/WEB-INF/web.xml");
webapp.setResourceBase(webappDirLocation);
handlerCollection.addHandler(webapp);
// Add the API part
ServletContextHandler apiContext = new ServletContextHandler(ServletContextHandler.SESSIONS);
apiContext.setContextPath("/d");
apiContext.addServlet(new ServletHolder(new DownloaderServlet()), "/*");
handlerCollection.addHandler(apiContext);
// Add both handlers to the server
server.setHandler(handlerCollection);
try {
server.start();
server.join();
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
Servlet code: Servlet代码:
@SuppressWarnings("serial")
@WebServlet
public class DownloaderServlet extends HttpServlet {
public DownloaderServlet(){}
@Override
protected void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
PrintWriter out = response.getWriter();
out.println("<html><body><h1>My Servlet</h1></body></html>");
}
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
}
Web.xml: Web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">
<welcome-file-list>
<welcome-file>index.html</welcome-file>
</welcome-file-list>
</web-app>
I think this is a bug in Jetty. 我认为这是Jetty中的错误。 Feedback is welcome.
欢迎反馈。 Either way adding servlet handler before webapp handler solved the problem:
无论哪种方式,在webapp处理程序解决之前都可以添加servlet处理程序:
HandlerCollection handlerCollection = new HandlerCollection();
// Add the API part
ServletContextHandler apiContext = new ServletContextHandler(ServletContextHandler.SESSIONS);
apiContext.setContextPath("/d");
apiContext.addServlet(new ServletHolder(new DownloaderServlet()), "/*");
handlerCollection.addHandler(apiContext);
// Add the GUI part
WebAppContext webapp = new WebAppContext();
webapp.setContextPath("/");
webapp.setDescriptor(webappDirLocation + "/WEB-INF/web.xml");
webapp.setResourceBase(webappDirLocation);
handlerCollection.addHandler(webapp);
// Add both handlers to the server
server.setHandler(handlerCollection);
This example was helpful in my efforts to debug this issue. 此示例对调试此问题很有帮助。
