Jetty 入门：安装，部署第一个web application

1 Jetty 简介

 

　   Jetty 是一个开源的servlet容器，它为基于Java的web内容，例如JSP和servlet提供运行环境。Jetty是使用Java语言编写的，它的 API以一组JAR包的形式发布。开发人员可以将Jetty容器实例化成一个对象，可以迅速为一些独立运行（stand-alone）的Java应用提供 网络和web连接。

 

　　Jetty 可以作为嵌入式服务器使用，Jetty的运行速度较快，而且是轻量级的，可以在Java中可以从test case中控制其运行。从而可以使自动化测试不再依赖外部环境，顺利实现自动化测试。

 

      Jetty is an open-source, standards-based, full-featured web server and servlet container implemented entirely in Java. It is released under the Apache 2.0 licence and is therefore free for commercial use and distribution.

 

 

2 Jetty 下载安装，启动与关闭

 

下载: http://jetty.mortbay.org/jetty/  目前的稳定版是 Jetty6，建议项目中使用此版本

 

安装: 和zip版的tomcat几乎一样，解压到你自己的目录即可

 

根目录下与操作密切相关的主要为：

 

（1 start.jar 用于启动jetty，最简单的方法：

 

java -jar startup.jar

 

这种方式等同于下面的启动方式； 关闭时ctrl+c 即可 ！

 

 

Running jetty6 is as simple as going to your jetty installion directory and typing:

java -jar start.jar etc/jetty.xml

This will start jetty and deploy a demo webapp available at:

http://localhost:8080/test

 

Stopping

Apart from stopping jetty with a cntrl-c in the same terminal window as you started it, you can
start Jetty so that it listens on a local port for stop commands:

java -DSTOP.PORT=8079 -DSTOP.KEY=secret -jar start.jar

The server can then be stopped using a different terminal window on the same machine:

java -DSTOP.PORT=8079 -DSTOP.KEY=secret -jar start.jar --stop

If the STOP.KEY property is ommitted from the start command, then a random key is printed on standard out. If the STOP.PORT is set to 0, a random available port is assigned and printed on stdout.

 

（2  webapps : 这就是部署项目的目录

 

 

3 Jetty 项目部署

 

（1 直接将项目文件夹放至 webapps下即可；

（2 将项目打包为war,放至webapps下即可！

 

 

是不是很简单呢？？？ 类似于tomcat,jboss ???  第一个项目都是这么简单的!

 

 

到这里，相信我们都可以自己开发和部署了；但是关于Jetty的具体配置调整和性能调优等，还需要更进一步的学习和实践才行！

 

 

Good Luck ！

另外，你使用struts等一些外部的jar,是不是都带齐了 ？

2 楼 bluky999 2010-03-31  

是不是端口的问题？ 确保8080没有被使用？ 

arsenepark 写道

我直接把war放到webapps下，出现这样的错误，不知道楼主遇到过没有。
我用maven2建的工程，在eclipse中调试好用，降war放到tomcat下也好用，就是放到jetty下出错

详细错误如下：
