最近，大概在去年年底， GlassFish開源團隊發布了GlassFish 4.0 beta 72作為升級版 。 阿倫·古普塔（Arun Gupta）在他的博客上發布了有關GlassFish 4 .0 beta 72的Maven坐標的文章。 該版本意義重大，因為該團隊將工件發布到了Maven存儲庫中。

2013年，我是新版Java EE 7用戶指南的作者 ，因此研究最新的GlassFish非常重要，尤其是因為它是該規范的參考實現。 我想實際研究和調查最新的Java Servlets 3.1，Web套接字和JAX-RS規范在服務器中的表現。

這是我昨晚編寫的用于執行GlassFish Embedded應用程序的Gradle構建腳本：

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 }

構建腳本的關鍵是依賴關系的順序。 我發現glassfish-embedded-all必須首先依賴列表，否則將找不到Hibernate Validator（bean驗證器）jar中的ValidationException。 異常消息為'javax.validation.ValidationException: Unable to load Bean Validation provider' 。

Gradle構建還引用了GlassFish Java存儲庫，這是第二個關鍵點。 這是Java應用程序代碼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();} }

該類將嵌入式GlassFish作為無容器構建的開始執行，這是James Ward和其他人創造的一個術語。 此類啟動GlassFish，等待一秒鐘，然后再次將其關閉。 通過在命令行gradle運行或通過IDE調用，該代碼可與Gradle一起使用。 我使用命令gradle想法來生成IDEA項目文件。

這是IntelliJ IDEA 12的示例輸出：

如果操作正確，您應該會在IDE中看到上面的輸出。 為了避免類路徑加載問題，在JDK 9之前，我們將不得不加倍注意。 我的Java EE 7用戶指南書預定于2013年夏季發布。
