jetty使用教程(嵌入eclipse开发)

在eclipse下面建一个java project

建立目录结构如下：

二级目录：

（备注jetty_test是工程的根目录，etc、lib、webRoot为其二级目录）

到jetty的官方网站（http://www.eclipse.org/jetty/）下载jetty的开发包；

我下载的jetty-hightide-8.0.0.v20110901.tar.gz；

把里面的lib目录的jar包和lib/jsp目录下面的jar包导入到工程里面

说明白，其实jetty.xml和webdefault.xml其实是在我下载的

jetty-hightide-8.0.0.v20110901.tar.gz里面的etc目录下面的jetty.xml和webdefault.xml

  <!--
 *  acceptRanges      If true, range requests and responses are
 *                    supported
 *
 *  dirAllowed        If true, directory listings are returned if no
 *                    welcome file  Forbidden.
 *
 *  welcomeServlets   If true, attempt to dispatch to welcome files
 *                    that are servlets, but only after no matching static
 *                    resources could be found. If false, then a welcome
 *                    file must exist on disk. If "exact", then exact
 *                    servlet matches are supported without an existing file.
 *                    Default is true.
 *
 *                    This must be false if you want directory listings,
 *                    but have index.jsp in your welcome file list.
 *
 *  redirectWelcome   If true, welcome files are redirected rather than
 *                    forwarded to.
 *
 *  gzip              If set to true, then static content will be served as
 *                    gzip content encoded if a matching resource is
 *                    found ending with ".gz"
 *
 *  resourceBase      Set to replace the context resource base
 *
 *  resourceCache     If set, this is a context attribute name, which the servlet
 *                    will use to look for a shared ResourceCache instance.
 *
 *  relativeResourceBase
 *                    Set with a pathname relative to the base of the
 *                    servlet context root. Useful for only serving static content out
 *                    of only specific subdirectories.
 *
 *  aliases           If True, aliases of resources are allowed (eg. symbolic
 *                    links and caps variations). May bypass security constraints.
 *
 *  maxCacheSize      The maximum total size of the cache or  for no cache.
 *  maxCachedFileSize The maximum size of a file to cache
 *  maxCachedFiles    The maximum number of files to cache
 *
 *  useFileMappedBuffer
 *                    If set to true, it will use mapped file buffer to serve static content
 *                    when using NIO connector. Setting this value to false means that
 *                    a direct buffer will be used instead of a mapped file buffer.
 *                    By default, this is set to true.
 *
 *  cacheControl      If set, all static content will have this value set as the cache-control
 *                    header.

而webdefault.xml基本可以不改，因为它是用来标识文件的语言格式，基本的一些配置；

jetty.xml我们可以做一定的修改；

例如说我们可以改下服务监听的端口号，如图：

web.xml：

（备注就是web请求的配置信息，例如说设置servlet的路由）

如下面配置：

<?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_3_0.xsd" version="3.0">
  <display-name></display-name>

  <servlet>

  </servlet>

  <servlet-mapping>
    <servlet-name>HelloWorldServlet</servlet-name>

  </servlet-mapping>

  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

好！我们现在就来建设一个如上面web.xml配置的servlet和index.jsp；

index.jsp页面

Index.jsp:

<%@ page language="java" contentType="text/html; charset=gb2312"
    pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<title>Insert title here</title>

<body>
hello jetty! 中国!
</body>
</html>

HelloWorldServlet.java文件：

package org.jetty.demo;

import java.io.IOException;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
//Servlet

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

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

        server.startServer();

    }
}

运行这个类相当于启动了整个工程：
