    public class HomeServlet extends HttpServlet {
    	private static final long serialVersionUID = 1L;
    	protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
    		System.out.println("request scheme: " + req.getScheme());
    		resp.getWriter().print("hello tomcat");
    	}
    }

http示例

package com.pp.server.tomcat;
    
    import org.apache.catalina.core.StandardContext;
    import org.apache.catalina.startup.Tomcat;
    import org.apache.catalina.startup.Tomcat.FixContextListener;
    
    public class EmbedTomcatHttp {
    	static final int port = 9080;
    	static final String docBase = "e:/tmp/tomcat";
    	public static void main(String[] args) throws Exception {
    		Tomcat tomcat = new Tomcat();
            tomcat.setPort(port);
            tomcat.setBaseDir(docBase);
            tomcat.getHost().setAutoDeploy(false);
            
            String contextPath = "/book";
            StandardContext context = new StandardContext();
            context.setPath(contextPath);
            context.addLifecycleListener(new FixContextListener());
            tomcat.getHost().addChild(context);
            
            tomcat.addServlet(contextPath, "homeServlet", new HomeServlet());
            context.addServletMappingDecoded("/home", "homeServlet");
            tomcat.start(); 
            tomcat.getServer().await();
    	}
    }
