二.配置简单的嵌入式jetty

修改类文件,类加载器就能重新加载修改过的类,测试就方便了,在开发web应用的时候,这样做似乎不是件容易事.tomcat maven组件会把应用打成war包,再上传到tomcat,重新部署再测试,虽然看起来一切都是自动化过程,当jar包又多又大时,你会感觉到这组件很忙,或许因为如此,有些人选择了jetty maven组件,jetty不用打成war包,直接从输出目录重新加载类,看起来要优雅点.当我们用gradle,jetty组件稳定但不支持servlet3,gretty不稳定...以后gradle会好的,相信总有一天!
maven和gradle的项目标准目录结构是相似的,如下:
src/main/java Application/Library sources
src/main/resources Application/Library resources
src/main/filters Resource filter files
src/main/config Configuration files
src/main/scripts Application/Library scripts
src/main/webapp Web application sources
src/test/java Test sources
src/test/resources Test resources
src/test/filters Test resource filter files
src/it Integration Tests (primarily for plugins)
src/assembly Assembly descriptors
src/site Site
LICENSE.txt Project's license
NOTICE.txt Notices and attributions required by libraries that the project depends on
README.txt Project's readme
而两者编译输出目录有差别,但基本不存在不便.
和前篇文件一样,选用了<<gradle的war插件>>简单开发的web应用来测试.没有找到tomcat方便的API设置额外的类路径.下文主要以jetty来实现这个嵌入式jetty

1.再新建一个gradle项目,build.gradle如下:

apply plugin: 'java'
sourceCompatibility = 1.7
version = '1.0'
repositories {
    mavenCentral()
}
dependencies {
    compile("org.eclipse.jetty:jetty-util-ajax:9.2.1.v20140609")
    compile("org.eclipse.jetty:jetty-deploy:9.2.1.v20140609")
    compile("org.eclipse.jetty:jetty-jmx:9.2.1.v20140609")
    compile("org.eclipse.jetty.websocket:javax-websocket-server-impl:9.2.1.v20140609")
    compile("org.eclipse.jetty.spdy:spdy-http-server:9.2.1.v20140609")
    compile("org.eclipse.jetty:jetty-proxy:9.2.1.v20140609")
    compile("org.eclipse.jetty:jetty-jsp:9.2.1.v20140609")
}
task jarWithoutResources(type: Jar,dependsOn:compileJava) {
    manifest{
        attributes 'Main-Class':'Start'
    }
    from("$buildDir/classes/main")
    archiveName("start.jar")
}

2.新建一个含有main方法的可执行类(此类的编写主要参考jetty官方文档:http://www.eclipse.org/jetty/documentation/current/using-annotations-embedded.html).
Start.java:

import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.webapp.WebAppContext;
public class Start {
    public static void main(String[] args) throws Exception {
        //Get parameters
        String resourceBase=PropertyUtil.getProperty("resourceBase");
        if (resourceBase==null) throw new Exception("resourceBase can not be null");
        String portTmp=PropertyUtil.getProperty("port");
        int port=portTmp==null?8080:Integer.valueOf(portTmp);
        String contextPath=PropertyUtil.getProperty("contextPath");
        contextPath=contextPath==null?"/":contextPath;
        String extraClasspath=PropertyUtil.getProperty("extraClasspath");
        extraClasspath=extraClasspath==null?"":extraClasspath;

        Server server = new Server(port);
        //Enable parsing of jndi-related parts of web.xml and jetty-env.xml
        org.eclipse.jetty.webapp.Configuration.ClassList classList = org.eclipse.jetty.webapp.Configuration.ClassList.setServerDefault(server);
        classList.addAfter("org.eclipse.jetty.webapp.FragmentConfiguration", "org.eclipse.jetty.plus.webapp.EnvConfiguration", "org.eclipse.jetty.plus.webapp.PlusConfiguration");
        classList.addBefore("org.eclipse.jetty.webapp.JettyWebXmlConfiguration", "org.eclipse.jetty.annotations.AnnotationConfiguration");
        //Create a WebAppContext
        WebAppContext webapp = new WebAppContext();
        webapp.setContextPath(contextPath);
        webapp.setResourceBase(resourceBase);
        webapp.setExtraClasspath(extraClasspath);
        server.setHandler(webapp);
        server.start();
        server.join();
    }
}

和上篇文章的war包配置的嵌入式jetty例子很相似,将setWar改成了setResourceBase和setExtraClasspath,另外上面利用PropertyUtil从.properties文件获取属性配置.
server.properties文件如下:

#默认为'8080'
port=8080
#默认为'/'
contextPath=/test
#必须指定
resourceBase=E:/idea/test/src/main/webapp
#默认为''
extraClasspath=E:/idea/test/build/classes/main/;E:/idea/test/build/resources/main/;E:/gradlerepo/caches/modules-2/files-2.1/org.springframework/spring-webmvc/3.2.8.RELEASE/b23357096216fee7fa658c3e0a28a4574d4d3a90/spring-webmvc-3.2.8.RELEASE.jar;

port,contextPath,resourceBase的设置都是容易理解的.额外的类路径extraClasspath指的意思:当启动jetty的时候,类加载器也从这些位置加载类文件.jar文件或目录要以分号或逗号分隔,并且是目录时,要以'/'结尾.上面例子的意思当启动这个嵌入式jetty,应先加载E:/idea/test/build/classes/main/,E:/idea/test/build/resources/main/两个目录下的文件和项目依赖的一些jar包.
至于这些依赖jar包路径可通过以下任务获得
task('jarPath')<<{
    println configurations.runtime.asPath
}
3.运行一下main方法,就可以通过浏览器来访问这个web应用了.
如果开发每个应用都要打开这个工程,再运行调试,这样当然不方便.我希望通过一个命令能直接运行就可以启动这个jetty.那么继续进行下面第4步.
4.从第3步的运行,可以拷贝出这个运行命令,但这个命令相当长,我测试终端里dos命令最大输入长度是8190,而这个命令很可能超过限制,那么可以写一个start.bat文件来执行就可以了.下面是我拷贝再修改后的start.bat文件
D:\jdk7\bin\java -Didea.launcher.port=7535 -Didea.launcher.bin.path=D:\idea\bin -Dfile.encoding=UTF-8 -classpath

5.把server.properties和start.bat拷贝到test应用的根目录下.双击start.bat就可以启动jetty了.关闭这个窗口就可以关闭jetty.当然也可以打开IDEA的terminal来运行,ctrl+c就可以退出命令关闭jetty.有了这个server.property,就可以随时嵌入到一个web项目来启动jetty


另外:http://www.jetbrains.com/idea/documentation/migration_faq.html
问题提到Q: What happened to incremental compilation? How do I compile my project?答案的解析里有说得编译的时机.在IDEA里你按ctrl+s,并不会即时编译,可以按ctrl+shift+f9编译当前文件.而ctrl+f9可以编译整个项目.

小结:这基本可以前面所说的需求,修改类,自动reload功能没实现,感觉还是不太实用.做成gradle插件,就更好了!但不想花太多心思.
