1.Jetty嵌入到Spring项目

try {              Server server = new Server(8080);                WebAppContext context = new WebAppContext();              context.setContextPath("/test");              context.setDescriptor(filePath + "/conf/web.xml"); // 指定web.xml配置文件              context.setResourceBase(filePath + "/conf/");// 指定webapp目录              context.setParentLoaderPriority(true);                server.setHandler(context);              server.start();              server.join();            } catch (Exception e) {              // TODO Auto-generated catch block              e.printStackTrace();          }

　　

 

2.Jetty添加Filter的方式有两种

 1.类似Tomcat，在web.xml中指定过滤器，但需要确定配置文件WEB-INF/web.xml 存在于webapp根目录

     
         
              
       
        filterName
               
       
        com.x.y.z.FilterClass
           
          
              
       
        /test
               
       
        filterName
           
      
     

　　

2.直接用addFilter API

主要用到 ServletContextHandler、FilterMapping、FilterHolder几个类

import java.io.IOException;import java.util.EnumSet;import java.util.Enumeration;import javax.servlet.DispatcherType;import javax.servlet.Filter;import javax.servlet.FilterChain;import javax.servlet.FilterConfig;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.eclipse.jetty.server.Server;import org.eclipse.jetty.servlet.FilterHolder;import org.eclipse.jetty.servlet.ServletContextHandler;import org.eclipse.jetty.servlet.ServletHandler;import org.eclipse.jetty.servlet.ServletHolder;public class TestEmbeddedFilter {    public static void main(String[] args) {        Server server = new Server(8082);        ServletContextHandler context = new ServletContextHandler(                ServletContextHandler.SESSIONS);        context.setContextPath("/");        ServletHandler handler = new ServletHandler();        ServletHolder sh = new ServletHolder(new MyServlet());        context.addServlet(sh, "/*");        FilterHolder fh = handler.addFilterWithMapping(MyFilter.class, "/*", EnumSet.of(DispatcherType.REQUEST));        fh.setInitParameter("initParamKey", "InitParamValue");        context.addFilter(fh, "/*", EnumSet.of(DispatcherType.REQUEST));        context.setHandler(handler);        server.setHandler(context);        try {            server.start();            // server.join();        } catch (Exception e) {            e.printStackTrace();        }    }    @SuppressWarnings("serial")    public static class MyServlet extends HttpServlet {        @Override        protected void doGet(HttpServletRequest request,                HttpServletResponse response) throws ServletException,                IOException {            response.setContentType("text/html");            response.setStatus(HttpServletResponse.SC_OK);            response.getWriter().println("
Hello MyServlet
");        }    }    public static class MyFilter implements Filter {        public void destroy() {            System.out.println("Stopping filter");        }        public void doFilter(ServletRequest request, ServletResponse response,                FilterChain chain) throws IOException, ServletException {            System.out.println("doFilter called with: " + request);            chain.doFilter(request, response);        }        public void init(FilterConfig filterConfig) throws ServletException {            Enumeration
     
       enums = filterConfig.getInitParameterNames();            while (enums.hasMoreElements()) {                String param = (String) enums.nextElement();                System.out.println(param + ":" + filterConfig.getInitParameter(param));            }        }    }}
