jetty 使用小记

<p>看到开源项目发布的时候都带一个 jsp 容器(jetty)。拿来做 demo、开发、调试的服务器还是很不错的。今天就小试下，主要把它运行起来。</p> <p>第一步下载：<a href="/misc/goto?guid=4959221551227468901">http://dist.codehaus.org/jetty/jetty-6.1.14/jetty-6.1.14.zip</a> 是目前最新的稳定版。解压到如E:\jetty-6.1.14，其中比较重要的目录是：etc、contexts、webapps。个人认为可以类比tomcat的conf、conf\Catalina\localhost、webapps目录。contexts是热部署用的。</p> <p>试运行下，可以把一个简单的web项目到到webapps目录下，或是*.war，如：web-demo（或web-demo.war）放到webapps目录下。</p> <p>E:\jetty-6.1.14>java -jar start.jar <br /> 2009-01-13 15:34:38.937::INFO: Logging to STDERR via org.mortbay.log.StdErrLog <br /> 2009-01-13 15:34:39.265::INFO: jetty-6.1.14 <br /> 2009-01-13 15:34:39.421::INFO: Deploy E:\jetty-6.1.14\contexts\javadoc.xml -> <a href="/misc/goto?guid=4959221551500282462">org.mortbay.jetty.handler.ContextHandler@15cda3f{/javadoc,file:/E:/jetty-6.1.14/javadoc/</a>} <br /> ... <br /> 2009-01-13 15:35:01.828::INFO: Opened E:\jetty-6.1.14\logs\2009_01_13.request.log <br /> 2009-01-13 15:35:01.953::INFO: Started <a href="/misc/goto?guid=4959221551584211660">SelectChannelConnector@127.0.0.1:8080</a> </p> <p>E:\jetty-6.1.14>java -jar start.jar<br /> 2009-01-13 15:34:38.937::INFO: Logging to STDERR via org.mortbay.log.StdErrLog<br /> 2009-01-13 15:34:39.265::INFO: jetty-6.1.14<br /> 2009-01-13 15:34:39.421::INFO: Deploy E:\jetty-6.1.14\contexts\javadoc.xml -> <a href="/misc/goto?guid=4959221551500282462">org.mortbay.jetty.handler.ContextHandler@15cda3f{/javadoc,file:/E:/jetty-6.1.14/javadoc/</a>}<br /> ...<br /> 2009-01-13 15:35:01.828::INFO: Opened E:\jetty-6.1.14\logs\2009_01_13.request.log<br /> 2009-01-13 15:35:01.953::INFO: Started <a href="/misc/goto?guid=4959221551584211660">SelectChannelConnector@127.0.0.1:8080</a><br /> 打开：<a href="/misc/goto?guid=4959221551686150260">http://localhost:8080/web-demo</a> ，恩有结果了。</p> <p>如果不把web-demo放到webapps目录下也可，在contexts目录下建立一个文件告诉jetty就行了。可以在contexts目录下复制test.xml为web-demo.xml，然后修改如下：</p> <pre class="brush:xml; toolbar: true; auto-links: false;"><?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd"> <Configure class="org.mortbay.jetty.webapp.WebAppContext"> <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --> <!-- Required minimal context configuration : --> <!-- + contextPath --> <!-- + war OR resourceBase --> <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --> <Set name="contextPath">/web-demo</Set> <Set name="war">e:/workspace/web-demo/WebContent</Set> <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --> <!-- Optional context configuration --> <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --> <Set name="extractWAR">false</Set> <Set name="copyWebDir">false</Set> <Set name="defaultsDescriptor"><SystemProperty name="jetty.home" default="."/>/etc/webdefault.xml</Set> <!-- <Set name="overrideDescriptor"><SystemProperty name="jetty.home" default="."/>/contexts/test.d/override-web.xml</Set> --> </Configure> <?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd"> <Configure class="org.mortbay.jetty.webapp.WebAppContext"> <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --> <!-- Required minimal context configuration : --> <!-- + contextPath --> <!-- + war OR resourceBase --> <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --> <Set name="contextPath">/web-demo</Set> <Set name="war">e:/workspace/web-demo/WebContent</Set> <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --> <!-- Optional context configuration --> <!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --> <Set name="extractWAR">false</Set> <Set name="copyWebDir">false</Set> <Set name="defaultsDescriptor"><SystemProperty name="jetty.home" default="."/>/etc/webdefault.xml</Set> <!-- <Set name="overrideDescriptor"><SystemProperty name="jetty.home" default="."/>/contexts/test.d/override-web.xml</Set> --> </Configure></pre> <br /> <p>war可以设置成绝对路径。然后再重启jetty试试看。好了， 对jetty的初步认识到这里。</p> <p>下面再来看下，怎么把它放到项目中。现我有一示例项目 e:/workspace/web-demo（称为project_home），里面的Web根目录是WebContent。在project_home建一个jetty目录，子目录如：contexts、etc、lib。把${jetty_home}/etc目录下的jetty.xml、webdefault.xml文件复制到${project_home}/jetty/etc目录中，把${jetty_home}/lib/jsp-2.1目录复制到${project_home}/jetty/lib目录下（如果不复制jsp-2.1或jsp-2.0也可以正常启动，只是不能解析jsp，打开主页时提示 JSP not support），同样把jetty-6.1.14.jar、jetty-util-6.1.14.jar、servlet-api-2.5-6.1.14.jar复制到${project_home}/jetty/lib目录下，${jetty_home}/start.jar复制到${project_home}/jetty目录下。</p> <p>接下来在${project_home}/jetty/contexts目录下加一个文件。可以是上面给出的web-demo.xml。不过war 可以改为</p> <pre class="brush:xml; toolbar: true; auto-links: false;"><Set name="war"><SystemProperty name="jetty.home" default="."/>/../WebContent</Set> <Set name="war"><SystemProperty name="jetty.home" default="."/>/../WebContent</Set></pre> <p>注释${project_home}/jetty/etc/jetty.xml文件中的：</p> <pre class="brush:xml;
