jetty嵌入式配置总结

Jetty配置到项目

1. 拷贝lib/jsp和lib下的所有jar包到项目中。
2. 在工程中创建文件夹jetty/etc、jetty/contexts
3. 拷贝jetty包中的jetty.xml和webdefault.xml到etc中，拷贝contexts中的test.xml到contexts中（貌似这个步骤可以不要，以后再试试）
4. 在项目中创建jsp目录
5. 新建一个servlet,名称为MyServlet.java
6. 新建一个类JettyDemo.java.
7. 以上两个类内容如下，访问http://localhost:9999/ss.do测试servlet是否好用。访问http://localhost:9999/index.jsp测试jsp是否好用。

 

JettyDemo.java

package org.jetty.demo;

import org.eclipse.jetty.server.Connector;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.bio.SocketConnector;
import org.eclipse.jetty.server.handler.ContextHandlerCollection;
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.webapp.WebAppContext;

public class JettyDemo {

    public static void main(String[] args) {
        Server server = new Server();
        try {
            Connector conn = new SocketConnector();
            conn.setPort(9999);
            server.setConnectors(new Connector[]{conn});

            ContextHandlerCollection handler = new ContextHandlerCollection();
            ServletContextHandler servlethandler = new ServletContextHandler();
            servlethandler.addServlet(MyServlet.class, "*.do");
            handler.addHandler(servlethandler);

            WebAppContext webapp = new WebAppContext();
            webapp.setContextPath("/");
            webapp.setResourceBase("./jsp");
            webapp.setDefaultsDescriptor("./jetty/etc/webdefault.xml");
            handler.addHandler(webapp);

            server.setHandler(handler);

//          XmlConfiguration conf = new XmlConfiguration("./src/jetty/etc/jetty.xml");
//          conf.configure(server);

            server.start();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

 

 

MyServlet.java

package org.jetty.demo;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class MyServlet extends HttpServlet{

    /**
     *
     */
    private static final long serialVersionUID = -6197211740957851460L;

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        System.out.println("doGet");
        resp.getWriter().write("hello");
        resp.getWriter().close();
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        System.out.println("doPost");
        super.doPost(req, resp);
    }

}

 

以上完毕。
