【轉】JBoss AS 7 快速上手

        JBoss AS7 最近發佈了 7.0.0.CR1 版本,CR意即Candidate Release(候選發佈版),是JBoss AS在Alpha → Beta以後相對比較完整的一個版本,包含了CDI,JAX-RS等諸多重要特性。此次的7.0.0.CR1版本代號White Rabbit(白兔子)。因爲採用了新的MSC內核和JBoss Modules架構,其運行和啓動速度真正作到了動若脫兔。讓咱們一塊兒來體驗下吧!java

首先是下載JBoss AS 7.0.0.CR1,訪問JBoss AS的下載頁面:web

http://www.jboss.org/jbossas/downloads

將最新版的JBoss AS7下載下來(本文撰寫時最新版本爲7.0.0.CR1,代號White Rabbit):shell

除了JBoss AS之外,咱們還能夠把quickstarts包一塊兒下載下來,這個包裏面含有一些樣例工程,能夠部署進JBoss AS 7,咱們稍後討論。apache

JBoss AS7的安裝包下載完成後,將其解壓。解壓縮完成後,咱們能夠看看AS7裏面都有什麼內容:服務器

/jboss-7.0.0.CR1$ ls
bin               docs              jboss-modules.jar standalone
bundles           domain            modules           welcome-content

能夠看到AS7的目錄結構和AS6及以前的版本有很大的不一樣了,這是因爲AS7的架構與以前的版本相比,經歷了從新架構和代碼重寫,有了本質上的飛躍。探討AS7的設計架構不是本文重點,咱們繼續來看如何運行及啓動它:進入bin目錄,能夠看到有一些命令可供咱們使用:架構

/jboss-7.0.0.CR1/bin$ ls
domain.bat          jboss-admin.bat     standalone.conf     wsconsume.sh
domain.conf         jboss-admin.sh      standalone.conf.bat wsprovide.bat
domain.conf.bat     scripts             standalone.sh       wsprovide.sh
domain.sh           standalone.bat      wsconsume.bat

        AS7提供的命令也和AS6有了很大的不一樣,熟悉的  run.sh 沒有了。取而代之的是 standalone.sh 和  domain.sh 。AS7再也不使用統一的  run.sh 加上啓動環境參數(default, all)的方式來管理服務,而是將啓動方式區分爲獨立運行(standalone)和域運行(domain)。AS7默認支持多域,在架構上面與原來的組播羣集有很大的不一樣,我會在隨後的文章中重點介紹。在這裏咱們能夠首先試玩下以獨立模式啓動AS7,使用standalone.sh(若是是在Windows下,運行standalone.bat)啓動AS7服務器:

從啓動日誌裏面能夠看出來,AS7使用了新的JBoss Module來加載模塊,這是AS7中全新的設計。此外,新的MSC內核的身影也能夠在日誌中看到。此外,默認啓動的模塊還包括XNIO高速IO,JCA子系統等。看一下最後一行,AS7的啓動時間,在個人Macbook Air 1.4Ghz Core Duo + 2GB內存的低配下達到了驚人的6秒。dom

        接下來咱們試着在AS7上面部署應用玩玩看,剛纔一塊兒下載的quickstart包有用了,裏面有一些可供部署了例子,咱們將壓縮包解開,使用裏面的numberguess例子,進入到numberguess目錄,執行mvn的部署命令:ide

/jboss-as-quickstarts-7.0.0.CR1/numberguess$ mvn jboss-as:deploy

確保機器裏面安裝了Maven 3,上面的命令應該能夠正確執行,執行完成後,這個例子會被部署到已經運行起來的AS7服務器上,並在AS7的日誌輸出以下:
22:20:28,184 INFO  [org.jboss.as.server.deployment] (MSC service thread 1-5) Starting deployment of "jboss-as-numberguess.war"
22:20:28,340 INFO  [org.jboss.weld] (MSC service thread 1-8) Processing CDI deployment: jboss-as-numberguess.war
22:20:28,390 INFO  [org.jboss.weld] (MSC service thread 1-7) Starting Services for CDI deployment: jboss-as-numberguess.war

22:20:28,437 INFO  [org.jboss.weld] (MSC service thread 1-3) Starting weld service

22:20:29,557 INFO  [org.jboss.as.server.controller] (pool-1-thread-1) Deployed "jboss-as-numberguess.war"


從日誌中咱們能夠看到,AS7檢測到待部署的項目須要Weld模塊,所以在此時AS7中的Weld模塊才被加載,這種加載方式被稱爲按需加載(on-demand),只有在須要的時候加載相應的模塊,從而大大加快了AS7自己的啓動速度。工具

咱們來玩玩看這個例子,訪問頁面:ui

http://127.0.0.1:8080/jboss-as-numberguess/home.jsf

是一個猜數字的遊戲:
