Jetty配置

## 前言 ##

现在越来越多的公司用Jetty而不用Tomcat了，原因是

> 1.Jetty更加轻量级  
> 2.Jetty更加灵活，可扩展性更高  
> 总结：Jetty更满足公有云的分布式环境的需求，而Tomcat更符合企业级环境。

## Jetty安装 ##

1.去Jetty官网下载Jetty服务器  
略过  
2.安装eclipse插件  
打开eclipse，依次点击菜单Help->Eclipse Marketplace，在Find后面的框中输入jetty，选择第一项进行install即可。

## 启动Jetty ##

Jetty启动有两种方式：一种代码，一种Run As

### 代码运行 ###

（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/][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

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：

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">

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

## JFinal使用Jetty ##

public class AppRun { 
    
        /** * 建议使用 JFinal 手册推荐的方式启动项目 * 运行此 main 方法可以启动项目，此main方法可以放置在任意的Class类定义中，不一定要放于此 */
        public static void main(String[] args) {
            JFinal.start("src/main/webapp", 8080, "/", 5);
        }
    }
