OSGi.基于Spring,Hibernate的Web应用快速开发指南

1 准备开发工具

a) SpringSource Tool Suite 2.9.2.REALEASE：解压即可
http://download.springsource.com/release/STS/2.9.2/dist/e3.7/springsource-tool-suite-2.9.2.RELEASE-e3.7.2-win32-x86_64.zip

b) Virgo Tomcat Server 3.5.0.RELEASE：解压即可
http://eclipse.stu.edu.tw//virgo/release/VTS/3.5.0.RELEASE/virgo-tomcat-server-3.5.0.RELEASE.zip

c) Virgo插件：通过Update site安装
http://download.eclipse.org/virgo/milestone/tooling

2 运行SpringSource Tool Suite
a)  进入SpringSource安装目录/sts-2.9.2.RELEASE，点击STS.exe

3 创建Virgo Runtime

a) Window->Preferences->Server->Runtime Environment->add

b) 输入vi过滤，选中EclicpseRT下的Virgo Runtime，勾选Create a new local server，点击Next

c) 点击browse，选中Virgo Tomcat Server安装目录确定

4 管理Bundle依赖

a) 打开Server视图
Window->Show View->Server

b) 打开Server编辑器
在Server view中双击已创建好的Virgo Server

c) 进入Repository标签页
在Server编辑器下方点击Repository

d) 下载hibernate相关bundle
在Repository标签页左上侧输入框输入antlr->点击search，勾选输入框下方搜索结果中的bundles:com.springsource.antlr，点击Repository标签页中间下方的download按钮，依次下载如下bundle
com.springsource.antlr-2.7.6.jar
com.springsource.com.mysql.jdbc-5.1.6.jar
com.springsource.javassist-3.3.0.ga.jar
com.springsource.net.sf.cglib-2.1.3.jar
com.springsource.org.apache.commons.collections-3.2.1.jar
com.springsource.org.apache.commons.dbcp-1.2.2.osgi.jar
com.springsource.org.apache.commons.pool-1.4.0.jar
com.springsource.org.dom4j-1.6.1.jar
com.springsource.org.hibernate.annotations.common-3.3.0.ga.jar
com.springsource.org.hibernate.annotations-3.4.0.GA.jar
com.springsource.org.hibernate-3.3.1.GA.jar
com.springsource.org.jgroups-2.5.1.jar

e) 查看下载完毕的bundle
下载的bundle存放在Virgo服务器安装目录/Repository/usr目录下，如果不可见，尝试点击右侧Refresh按钮或右下方Update the bundle and library index链接，Virgo服务器安装目录/Repository/ext目录下存放的是服务器自带的bundle

i) 定义服务引用
WEB-INF/applicationContext.xml

1 <? xml version = " 1.0 " encoding = " UTF-8 " ?>
2 < beans xmlns = " http://www.springframework.org/schema/beans "
3 xmlns:xsi = " http://www.w3.org/2001/XMLSchema-instance " xmlns:osgi = " http://www.springframework.org/schema/osgi "
4 xmlns:context = " http://www.springframework.org/schema/context "
5 xsi:schemaLocation = " http://www.springframework.org/schema/beans
6 http: // www.springframework.org/schema/beans/spring-beans.xsd
7 http: // www.springframework.org/schema/osgi
8 http: // www.springframework.org/schema/osgi/spring-osgi.xsd
9 http: // www.springframework.org/schema/context
