jetty在项目中的应用

jetty是一个轻量级容器，你可以使用它作为生产应用服务器，不过我一般用它来做开发环境的启动容器。使用main函数就可以运行起来，使用非常方便。至于生产环境，可替代的方案较多，故而在开发环境使用jetty作为我的应用中间件。
一 maven插件jetty方式
在pom.xml中添加下面的插件，通过jetty:run -Djetty.port=8081可启动服务

<plugin>    <groupId>org.eclipse.jetty</groupId>    <artifactId>jetty-maven-plugin</artifactId>    <version>9.1.6.v20160112</version>    <configuration>                      <scanIntervalSeconds>10</scanIntervalSeconds>        <webApp>            <contextPath>/webIM</contextPath>        </webApp>    </configuration></plugin>

二 外置jetty的方式
这种方式比较自由
1 pom.xml
在pom.xml中引入jetty相关的jar。

<jetty.version>8.1.16.v20140903</jetty.version><!-- jetty begin -->        <dependency>            <groupId>org.eclipse.jetty</groupId>            <artifactId>jetty-webapp</artifactId>            <scope>test</scope>        </dependency>        <dependency>            <groupId>org.eclipse.jetty</groupId>            <artifactId>jetty-jsp</artifactId>            <scope>test</scope>        </dependency>        <!-- jetty end -->

2 src/test/resources
这个目录主要配置jetty相关的xml的配置

2.1 jetty.xml

3 src/test/java

3.1 JettyFactory.java
主要jetty开发环境的虚拟目录通过uploadContext.setContextPath和uploadContext.setResourceBase来实现，注意下方代码

import java.util.List;import org.apache.commons.lang3.StringUtils;import org.eclipse.jetty.server.Connector;import org.eclipse.jetty.server.Handler;import org.eclipse.jetty.server.Server;import org.eclipse.jetty.server.handler.ContextHandlerCollection;import org.eclipse.jetty.server.nio.SelectChannelConnector;import org.eclipse.jetty.webapp.WebAppClassLoader;import org.eclipse.jetty.webapp.WebAppContext;import com.google.common.collect.Lists;/** * 创建Jetty Server的工厂类. *  * @author calvin */public class JettyFactory {    private static final String DEFAULT_WEBAPP_PATH = "src/main/webapp";    private static final String WINDOWS_WEBDEFAULT_PATH = "src/test/resources/jetty/webdefault-windows.xml";    /**     * 创建用于开发运行调试的Jetty Server, 以src/main/webapp为Web应用目录.     */    public static Server createServerInSource(int port, String contextPath) {        Server server = new Server();        // 设置在JVM退出时关闭Jetty的钩子。        server.setStopAtShutdown(true);        SelectChannelConnector connector = new SelectChannelConnector();        connector.setPort(port);        // 解决Windows下重复启动Jetty居然不报告端口冲突的问题.        connector.setReuseAddress(false);        server.setConnectors(new Connector[] { connector });        // 上下文        ContextHandlerCollection contextHandlerCollection = new ContextHandlerCollection();        // 当前应用        WebAppContext webContext = new WebAppContext(DEFAULT_WEBAPP_PATH, contextPath);        // 修改webdefault.xml，解决Windows下Jetty Lock住静态文件的问题.        webContext.setDefaultsDescriptor(WINDOWS_WEBDEFAULT_PATH);        contextHandlerCollection.addHandler(webContext);        // 虚拟目录        WebAppContext uploadContext = new WebAppContext();        uploadContext.setContextPath("/abs/upload");        uploadContext.setResourceBase("E:/upload");        contextHandlerCollection.addHandler(uploadContext);        //        server.setHandler(contextHandlerCollection);        return server;    }    private static WebAppContext getWebAppContext(Server server){        ContextHandlerCollection contextHandlerCollection = (ContextHandlerCollection) server.getHandler();        Handler[] handlers = contextHandlerCollection.getHandlers();        WebAppContext context = null;        if (handlers!=null && handlers.length>0){            for (Handler handler:handlers){                if (((WebAppContext)handler).getContextPath().equals(QuickStartServer.CONTEXT)){                    context = (WebAppContext)handler;                }            }        }        return context;    }    /**     * 设置除jstl-*.jar外其他含tld文件的jar包的名称.     * jar名称不需要版本号，如sitemesh, shiro-web     */    public static void setTldJarNames(Server server, String... jarNames) {        WebAppContext context = getWebAppContext(server);        List<String> jarNameExprssions = Lists.newArrayList(".*/jstl-[^/]*\\.jar$", ".*/.*taglibs[^/]*\\.jar$");        for (String jarName : jarNames) {            jarNameExprssions.add(".*/" + jarName + "-[^/]*\\.jar$");        }        context.setAttribute("org.eclipse.jetty.server.webapp.ContainerIncludeJarPattern",                StringUtils.join(jarNameExprssions, '|'));    }    /**     * 快速重新启动application，重载target/classes与target/test-classes.     */    public static void reloadContext(Server server) throws Exception {        WebAppContext context = getWebAppContext(server);        System.out.println("[INFO] Application reloading");        context.stop();        WebAppClassLoader classLoader = new WebAppClassLoader(context);        classLoader.addClassPath("target/classes");        classLoader.addClassPath("target/test-classes");        context.setClassLoader(classLoader);        context.start();        System.out.println("[INFO] Application reloaded");    }}

3.2 Profiles.java

/** * Spring profile 常用方法与profile名称。 *  * @author calvin */public class Profiles {    public static final String ACTIVE_PROFILE = "spring.profiles.active";    public static final String DEFAULT_PROFILE = "spring.profiles.default";    public static final String PRODUCTION = "production";    public static final String DEVELOPMENT = "development";    public static final String UNIT_TEST = "test";    public static final String FUNCTIONAL_TEST = "functional";    /**     * 在Spring启动前，设置profile的环境变量。     */    public static void setProfileAsSystemProperty(String profile) {        System.setProperty(ACTIVE_PROFILE, profile);    }}

3.3 QuickStartServer.java
运行main函数即可启动服务。

import org.eclipse.jetty.server.Server;/** * 使用Jetty运行调试Web应用, 在Console输入回车快速重新加载应用. *  * @author calvin */public class QuickStartServer {    public static final int PORT = 8097;    public static final String CONTEXT = "/abs";    public static final String[] TLD_JAR_NAMES = new String[] {"spring-webmvc", "shiro-web"};    public static void main(String[] args) throws Exception {        // 设定Spring的profile        Profiles.setProfileAsSystemProperty(Profiles.DEVELOPMENT);        // 启动Jetty        Server server = JettyFactory.createServerInSource(PORT, CONTEXT);        JettyFactory.setTldJarNames(server, TLD_JAR_NAMES);        try {            server.start();            System.out.println("[INFO] 服务启动  http://localhost:" + PORT + CONTEXT);            System.out.println("[HINT] 按回车迅速重启");            // 等待用户输入回车重载应用.            while (true) {                char c = (char) System.in.read();                if (c == '\n') {                    JettyFactory.reloadContext(server);                }            }        } catch (Exception e) {            e.printStackTrace();            System.exit(-1);        }    }}

三 linux中的方式
jetty官方下载地址,我下载的是9.2.21.v20170120针对jdk1.7的版本

# 安装比较简单cd /applicationunzip jetty-distribution-9.2.21.v20170120.zipln -s jetty-distribution-9.2.21.v20170120 jetty# 配置jetty环境变量,注意要source /etc/profile，使之生效JETTY_HOME=/application/jettyexport JETTY_HOMEexport PATH=$PATH:$JETTY_HOME/bin# jetty的启动与关闭,jetty的端口默认为8080jetty.sh startjetty.sh stop

您可参考Jetty应用服务器的安装详解，见其他jetty描述,我这里只写我自己感受的东西。
Jetty实战之 安装 运行 部署，这篇文章针对jetty8.x版本做了说明，但是jetty9.x版本中配置文件有很大变化，对新版本已无太多参考价值。
tomcat中webapps中的war会被解压，但是我看jetty上却没有。原来jetty部署项目是不需要关掉服务，直接部署就可以。jetty可以通过start.ini中jetty.port属性来更改服务的端口。

如果jetty不解压war，那么jetty如何实现增量部署的呢。
