注：本文来源于：《eclipse中jetty插件安装》

一.eclipse中jetty插件安装：

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。

二.jetty插件的使用：

安装成功后可能要重启eclipse:
然后开始配置：
Run》run configurations》
在Jetty Webapp》右键》new，Browser想要启动的项目，配置端口号(我配的是8080),Arguments需要指向一个jetty.xml文件(这个文件可以从jetty网站上下载到，下面我也会贴出来)

上面的jetty.xml文件如下：

<?xml version="1.0"?>

请注意更改端口号

之后Apply,run,即可快速启动该项目。
通过：http://localhost:8080/demo2/即可访问工程
上述模式，仅是运行模式，还不能debug。
debug与上面唯一的不同就是要由：
Run》debug configurations》进入配置，其它完全一样，启动后，即可设置断点进行配置。
