GlassFish 4升级的构建，Gradle和嵌入式应用服务器

最近，大概在去年年底， GlassFish开源团队发布了GlassFish 4.0 beta 72作为升级版 。 阿伦·古普塔（Arun Gupta）在他的博客上发布了有关GlassFish 4 .0 beta 72的Maven坐标的文章。该版本意义重大，因为该团队将工件发布到了Maven存储库中。

2013年，我是新版Java EE 7用户指南的作者 ，因此研究最新的GlassFish非常重要，尤其是因为它是该规范的参考实现。我想实际研究和调查最新的Java Servlets 3.1，Web套接字和JAX-RS规范在服务器中的表现。

这是我昨晚编写的用于执行GlassFish Embedded应用程序的Gradle构建脚本：

apply plugin: 'java'
apply plugin: 'maven'
apply plugin: 'eclipse'
apply plugin: 'idea'group = 'com.javaeehandbook.book1'
archivesBaseName = 'ch06-servlets-basic'
version = '1.0'repositories {mavenCentral()maven {url 'https://maven.java.net/content/groups/promoted'}maven {url 'http://repository.jboss.org/nexus/content/groups/public'}
}dependencies {compile 'org.glassfish.main.extras:glassfish-embedded-all:4.0-b72'compile 'javax:javaee-api:7.0-b72'testCompile 'junit:junit:4.10'
}// Override Gradle defaults - a force an exploded JAR view
sourceSets {main {output.resourcesDir = 'build/classes/main'output.classesDir = 'build/classes/main'}test {output.resourcesDir = 'build/classes/test'output.classesDir = 'build/classes/test'}
}task(run, dependsOn: 'classes', type: JavaExec) {description = 'Runs the main application'main = 'je7hb.common.webcontainer.embedded.glassfish.EmbeddedRunner'classpath = sourceSets.main.runtimeClasspath
}

构建脚本的关键是依赖关系的顺序。我发现glassfish-embedded-all必须首先依赖列表，否则将找不到Hibernate Validator（bean验证器）jar中的ValidationException。异常消息为'javax.validation.ValidationException: Unable to load Bean Validation provider' 。

Gradle构建还引用了GlassFish Java存储库，这是第二个关键点。这是Java应用程序代码EmbeddedRunner：

package je7hb.common.webcontainer.embedded.glassfish;import org.glassfish.embeddable.*;
import java.io.*;
import java.util.*;
import java.util.concurrent.atomic.AtomicBoolean;public class EmbeddedRunner {private int port;private AtomicBoolean initialized = new AtomicBoolean();private GlassFish glassfish;public EmbeddedRunner(int port) {this.port = port;}public EmbeddedRunner init() throws Exception{if ( initialized.get() ) {throw new RuntimeException('runner was already initialized');}BootstrapProperties bootstrapProperties = new BootstrapProperties();GlassFishRuntime glassfishRuntime = GlassFishRuntime.bootstrap(bootstrapProperties);GlassFishProperties glassfishProperties = new GlassFishProperties();glassfishProperties.setPort('http-listener', port);String [] paths = System.getProperty('java.class.path').split(File.pathSeparator);for (int j=0; j<paths.length; ++j) {System.out.printf('classpath[%d] = %s\n', j, paths[j]);}glassfish = glassfishRuntime.newGlassFish(glassfishProperties);initialized.set(true);return this;}private void check() {if ( !initialized.get() ) {throw new RuntimeException('runner was not initialised');}}public EmbeddedRunner start() throws Exception{check();glassfish.start();return this;}public EmbeddedRunner stop() throws Exception{check();glassfish.stop();return this;}public static void main(String args[]) throws Exception {EmbeddedRunner runner = new EmbeddedRunner(8080).init().start();Thread.sleep(1000);runner.stop();}
}

该类将嵌入式GlassFish作为无容器构建的开始执行，这是James Ward和其他人创造的一个术语。此类启动GlassFish，等待一秒钟，然后再次将其关闭。通过在命令行gradle运行或通过IDE调用，该代码可与Gradle一起使用。我使用命令gradle想法来生成IDEA项目文件。

这是IntelliJ IDEA 12的示例输出：

如果操作正确，您应该会在IDE中看到上面的输出。为了避免类路径加载问题，在JDK 9之前，我们将不得不加倍注意。我的Java EE 7用户指南书预定于2013年夏季发布。
