你可以通过浏览器访问http://localhost:8080.。然而在 JETTYHOME/webapps目录下并没有部署任何web应用,所以你将会看到一个Jetty提供的404错误页面,并不推荐在 JETTY_HOME下运行Jetty,而是建议运行一个Jetty基础应用。错误页面如下
> cd $JETTY_HOME/demo-base/ > java -jar $JETTY_HOME/start.jar
成功运行将有如下信息输出:

现在可以通过浏览器访问 http://localhost:8080, 此时可以看到一个Jetty的欢迎页面,页面上包含几个简单的例子,欢迎页面如下
警告
示例的web应用程序不一定是绝对安全的,所以不应该部署在生产环境上。
你可以通过以下命令查看示例应用的配置信息
> cd $JETTY_HOME/demo-base/ > java -jar $JETTY_HOME/start.jar --list-modules ... > java -jar %JETTY_HOME/start.jar --list-config ...
–list-modules:此命令将返回当前服务所有可用的模块,同时也会显示本地的模块,信息包括模块实现的顺序,依赖模块以及相应的jar信息

以上命令是Linux下的命令,简单解释:创建一个JETTY_BASE环境变量,并创建指定的文件夹,在此文件夹下运行start.jar时提示没有可以启动的东西,系统退出,此时输入java -jar JETTYHOME/start.jar−−add−to−startd=http,deploy命令为当前基目录添加标准文件及文件夹,然后java−jar JETTY_HOME/start.jar运行即可运行成功。在Windows下操作如下:
> cd $JETTY_BASE > java -jar $JETTY_HOME/start.jar jetty.http.port=8081 ...
另外,可以将要设置的端口属性添加到start.ini或者start.d/http.ini文件中。默认情况,在start.d/http.ini文件中定义的jetty.http.port属性可以被修改成另一个值。
提示
配置属性信息通过如下方式获得
- 首先去start.d/http.ini文件中找jetty.http.port=8080配置信息,若找到配置端口即为指定端口
- 根据模块modules/http.mod文件找到指定配置默认为etc/jetty-http.xml,在此配置文件中有jetty.http.port配置信息,若找到即为此端口配置
- 若上面两个都没有,则随机一个没有使用的端口
> java -jar $JETTY_HOME/start.jar --add-to-startd=https,http2 [...] > java -jar $JETTY_HOME/start.jar [...] 2015-06-04 13:52:01.933:INFO:oejs.ServerConnector:main: Started ServerConnector@6f1fba17{SSL,[ssl, alpn, h2, http/1.1]}{0.0.0.0:8443} [...]
–add-to-startd:此命令在ini文件中设置有效的配置信息,使HTTPS和HTTP2支持SSL连接
> cd $JETTY_BASE
> java -jar $JETTY_HOME/start.jar jetty.ssl.port=8444
除了在命令行增加参数的方法外,还可以在start.ini和start.d/*.ini文件中进行配置,所以如果用户使用–add-to-startd命令来使HTTPS生效,同样也可以在start.d/https.ini文件中进行修改。
> java -jar $JETTY_HOME/start.jar --help
提示
在Jetty9,只有Jetty基路径下的配置文件被编辑,属性才会被修改
Note
常见典型的模块配置信息通长很少被改动,*.mod文件通常位于 JETTYHOME/modules/文件夹下,但是额外增加的或者编辑过的通常放在 JETTY_BASE/module下,如果一个模块需要被修改,最好的做法是在修改前从 JETTYHOME/modules/拷贝∗.mod到 JETTY_BASE/modules/
XML files:
xml文件一般用与IoC以及spring使用,用在命令行或者模块定义中。xml文件里面的配置将被注入到描述服务的一个对象里。通常改变属性的方法是改变对应的ini文件。xml文件通常放在 JETTYHOME/etc/下,但是新增的或者被编辑的xml应该被放在 JETTY_BASE/etc/下,如果xml配置文件有修改的必要,最好的做法是在修改前将xml文件从 JETTYHOME/etc拷贝到 JETTY_BASE/etc/ 。Note
通常web应用的web.xml文件应该在WEB-INF/web.xml位置被发现,Jetty还支持多个web.xml,可以在 WEB-INF/web.xml文件加载前或者加载后加载(使用方法见test.xml)

Note
虚拟主机不能配置连接,用户应该通过虚拟主机的context来实现它们的相应。
Note
Jetty9同时支持连接协议(HTTP,HTTPS,AJP,SPDY)和自然连接(NIO或者BIO),Jetty9以后只有一个主要的连接器ServerConnector
Note
servlet规范定一个web应用。在Jetty规范中一个标准的web项目必须有一个标准的WEB-INF/web.xml文件,用来配置classpath,资源,session处理,登录,以及servlet,jsp,以及静态资源。标准的web应用需要很少的额外的配置文件。

还有一种做法是,不用增加配置文件,在war文件同目录,建一个同名的xml文件,内容如下:
DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://www.eclipse.org/jetty/configure_9_0.dtd">class="org.eclipse.jetty.webapp.WebAppContext"> default="."/>/webapps/test.war /test
配置例子可以参照$JETTY_HOME/webapps/test.xml
...... BASIC Test Realm
这个例子使用名为Test Realm.的验证,但是没有说明其是怎么实现的,在Jetty中有几种实现方式,其中一种是HashLoginService可以读取登录用户,并在配置文件中查找,为了配置HashLoginService用来匹配Test Realm,可以配置$JETTY_BASE/etc/test-realm.xml文件,并且该文件必须在start.ini或者start.d/server.ini中设置。
class="org.eclipse.jetty.server.Server"> class="org.eclipse.jetty.security.HashLoginService"> Test Realm default="etc/realm.properties"/> 0 class="org.eclipse.jetty.util.log.Log" name="rootLogger"> demo test-realm is deployed. DO NOT USE IN PRODUCTION!
通过创建和配置LoginService到web应用中,当部署应用时,会通过名字去寻找匹配的登录Service。
