首先需要安装JDK，自行解决

下载jetty安装包http://dist.codehaus.org/jetty/

我下载的是8.1.15

tar -xzvf *.tar.gz

解压完之后，基本就可以用了

webapps下有一些demo的war包

启动jetty服务：java -jar start.jar  默认端口8080

访问http://localhost:8080就可以了

现在开始部署你自己的war包

加入你的war包已经有了，名字是abc.war

那么将该war包放到webapps下面

重新启动jetty

访问http://localhost:8080/abc即可访问

如果你的war包名字很复杂不想修改，但是访问路径时希望简单

你可以复制context目录下的test.xml为XXX.xml 然后修改该文件内容

<?xml version="1.0"  encoding="ISO-8859-1"?><!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd"><!-- ==================================================================Configure and deploy the test web application in $(jetty.home)/webapps/testNote.

所以现在重新启动jetty服务，访问http://localhost:8080/hello即可访问了

至此jetty的安装及简单使用就结束了！
