概述
jetty是什么？
jetty是轻量级的web服务器和servlet引擎。
它的最大特点是：可以很方便的作为嵌入式服务器。
它是eclipse的一个开源项目。不用怀疑，就是你常用的那个eclipse。
它是使用Java开发的，所以天然对Java支持良好。
什么是嵌入式服务器？
以jetty来说明，就是只要引入jetty的jar包，可以通过直接调用其API的方式来启动web服务。
用过Tomcat、Resin等服务器的朋友想必不会陌生那一套安装、配置、部署的流程吧，还是挺繁琐的。使用jetty，就不需要这些过程了。
jetty非常适用于项目的开发、测试，因为非常快捷。如果想用于生产环境，则需要谨慎考虑，它不一定能像成熟的Tomcat、Resin等服务器一样支持企业级Java EE的需要。
jetty的嵌入式启动
我觉得嵌入式启动方式的一个好处在于：可以直接运行项目，无需每次部署都得再配置服务器。
jetty的嵌入式启动使用有两种方式：
API方式
maven插件方式
API方式
添加maven依赖
<dependency>
<groupId>org.eclipse.jetty</groupId> <artifactId>jetty-webapp</artifactId> <version>9.3.2.v20150730</version> <scope>test</scope> </dependency> <dependency> <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-annotations</artifactId> <version>9.3.2.v20150730</version> <scope>test</scope> </dependency> <dependency> <groupId>org.eclipse.jetty</groupId> <artifactId>apache-jsp</artifactId> <version>9.3.2.v20150730</version> <scope>test</scope> </dependency> <dependency> <groupId>org.eclipse.jetty</groupId> <artifactId>apache-jstl</artifactId> <version>9.3.2.v20150730</version> <scope>test</scope> </dependency>官方的启动代码
public class SplitFileServer { public static void main( String[] args ) throws Exception { // 创建Server对象，并绑定端口 Server server = new Server(); ServerConnector connector = new ServerConnector(server); connector.setPort(8090); server.setConnectors(new Connector[] { connector }); // 创建上下文句柄，绑定上下文路径。这样启动后的url就会是:http://host:port/context ResourceHandler rh0 = new ResourceHandler(); ContextHandler context0 = new ContextHandler(); context0.setContextPath("/"); // 绑定测试资源目录（在本例的配置目录dir0的路径是src/test/resources/dir0） File dir0 = MavenTestingUtils.getTestResourceDir("dir0"); context0.setBaseResource(Resource.newResource(dir0)); context0.setHandler(rh0); // 和上面的例子一样 ResourceHandler rh1 = new ResourceHandler(); ContextHandler context1 = new ContextHandler(); context1.setContextPath("/"); File dir1 = MavenTestingUtils.getTestResourceDir("dir1"); context1.setBaseResource(Resource.newResource(dir1)); context1.setHandler(rh1); // 绑定两个资源句柄 ContextHandlerCollection contexts = new ContextHandlerCollection(); contexts.setHandlers(new Handler[] { context0, context1 }); server.setHandler(contexts); // 启动 server.start(); // 打印dump时的信息 System.out.println(server.dump()); // join当前线程 server.join(); } }直接运行Main方法，就可以启动web服务。
注：以上代码在eclipse中运行没有问题，如果想在Intellij中运行还需要为它指定配置文件。
如果想了解在Eclipse和Intellij都能运行的通用方法可以参考我的github代码示例。
我的实现也是参考springside的方式。
代码行数有点多，不在这里贴代码了。
Maven插件方式
如果你熟悉maven，那么实在太简单了
注： Maven版本必须在3.3及以上版本。
(1) 添加maven插件
<plugin>
<groupId>org.eclipse.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <version>9.3.12.v20160915</version> </plugin>(2) 执行maven命令：
mvn jetty:run讲真，就是这么简单。jetty默认会为你创建一个web服务，地址为127.0.0.1:8080。
当然，你也可以在插件中配置你的webapp环境
<plugin>
<groupId>org.eclipse.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <version>9.3.12.v20160915</version> <configuration> <webAppSourceDirectory>${project.basedir}/src/staticfiles</webAppSourceDirectory> <!-- 配置webapp --> <webApp> <contextPath>/</contextPath> <descriptor>${project.basedir}/src/over/here/web.xml</descriptor> <jettyEnvXml>${project.basedir}/src/over/here/jetty-env.xml</jettyEnvXml> </webApp> <!-- 配置classes --> <classesDirectory>${project.basedir}/somewhere/else</classesDirectory> <scanClassesPattern> <excludes> <exclude>**/Foo.class</exclude> </excludes> </scanClassesPattern> <scanTargets> <scanTarget>src/mydir</scanTarget> <scanTarget>src/myfile.txt</scanTarget> </scanTargets> <!-- 扫描target目录下的资源文件 --> <scanTargetPatterns> <scanTargetPattern> <directory>src/other-resources</directory> <includes> <include>**/*.xml</include> <include>**/*.properties</include> </includes> <excludes> <exclude>**/myspecial.xml</exclude> <exclude>**/myspecial.properties</exclude> </excludes> </scanTargetPattern> </scanTargetPatterns> </configuration> </plugin>官方给的jetty-env.xml范例
<?xml version="1.0"?> <!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd"> <Configure class="org.eclipse.jetty.webapp.WebAppContext"> <!-- Add an EnvEntry only valid for this webapp --> <New id="gargle" class="org.eclipse.jetty.plus.jndi.EnvEntry"> <Arg>gargle</Arg> <Arg type="java.lang.Double">100</Arg> <Arg type="boolean">true</Arg> </New> <!-- Add an override for a global EnvEntry --> <New id="wiggle" class="org.eclipse.jetty.plus.jndi.EnvEntry"> <Arg>wiggle</Arg> <Arg type="java.lang.Double">55.0</Arg> <Arg type="boolean">true</Arg> </New> <!-- an XADataSource --> <New id="mydatasource99" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg>jdbc/mydatasource99</Arg> <Arg> <New class="com.atomikos.jdbc.SimpleDataSourceBean"> <Set name="xaDataSourceClassName">org.apache.derby.jdbc.EmbeddedXADataSource</Set> <Set name="xaDataSourceProperties">databaseName=testdb99;createDatabase=create</Set> <Set name="UniqueResourceName">mydatasource99</Set> </New> </Arg> </New> </Configure>参考
