jetty 使用servlet

renshanshan

　　在嵌入式Jetty中，有时候我们想运行一些的Servlet，此时就需要创建创建Context，然后让自己的Servlet运行在这些ServletContext中。

package hb.jetty;
import java.io.IOException;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

class MyServlet extends HttpServlet{
@Override  
protected void doGet(HttpServletRequest req, HttpServletResponse resp)  
throws ServletException, IOException {  
System.out.println("doGet MyServlet");  
}  
@Override  
protected void doPost(HttpServletRequest req, HttpServletResponse resp)  
throws ServletException, IOException {  
System.out.println("doPost MyServlet");  
super.doPost(req, resp);  
}  
@Override
public void init(ServletConfig servletConfig) throws ServletException {
System.out.println("MyServlet");
}
}

package hb.jetty;
import java.io.IOException;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

class MyServlet2 extends HttpServlet{
@Override  
protected void doGet(HttpServletRequest req, HttpServletResponse resp)  
throws ServletException, IOException {  
System.out.println("doGet MyServlet2");  
}  
@Override  
protected void doPost(HttpServletRequest req, HttpServletResponse resp)  
throws ServletException, IOException {  
System.out.println("doPost MyServlet2");  
super.doPost(req, resp);  
}  
@Override
public void init(ServletConfig servletConfig) throws ServletException {
System.out.println("MyServlet2");
}
}

package hb.jetty;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.servlet.ServletHolder;
public class ServletContextServer {
public static void main(String[] args) throws Exception {
// TODO Auto-generated method stub
Server server = new Server(8080);  
ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);  
//相当于工程目录，如果是myweb，则http://localhost:port/myweb/
context.setContextPath("/");
server.setHandler(context);  
// http://localhost:8080/servlet1  
context.addServlet(new ServletHolder(new MyServlet()), "/servlet1");  
// http://localhost:8080/servlet1/2   
context.addServlet(new ServletHolder(new MyServlet2()), "/servlet1/2");  
server.start();  
server.join();  
}
}
