本文介绍如何在JRuby环境中利用Maven管理依赖并集成Spring框架。通过具体步骤展示如何安装Java库，配置Spring上下文及加载Beans。此外还提供了搜索和安装开源包的方法。

之前开发了 java_side ，主要是便于 jruby 中使用基于 maven 管理的 java 三方包和基于 spring 管理的运行时服务，不过现在 jruby 1.6 以后 maven 这件事可以不必那么麻烦了，根据这篇blog ，我把自己试验的例子贴出来供参考：

下载

$ jruby -S gem install mvn:org.springframework:spring
Successfully installed mvn:commons-logging:commons-logging-1.1.1-java
Successfully installed mvn:org.springframework:spring-2.5.6-java
2 gems installed
Installing RDoc documentation for mvn:commons-logging:commons-logging-1.1.1-java...
Installing RDoc documentation for mvn:org.springframework:spring-2.5.6-java...

使用

$ jruby -S irb
jruby-1.6.2 :001 > require 'java'
 => true 
jruby-1.6.2 :002 > require 'rubygems'
 => true 
jruby-1.6.2 :003 > require 'mvn:org.springframework:spring'
 => true 
jruby-1.6.2 :004 > $CLASSPATH << '/home/john/mypro/java/conf'
 => ["file:/home/john/.rvm/gems/jruby-1.6.2/gems/mvn:org.springframework:spring-2.5.6-java/lib/maven/org.springframework/spring.jar", "file:/home/john/.rvm/gems/jruby-1.6.2/gems/mvn:commons-logging:commons-logging-1.1.1-java/lib/maven/commons-logging/commons-logging.jar", "file:/home/john/mypro/java/conf/"] 
jruby-1.6.2 :005 > context = org.springframework.context.support.ClassPathXmlApplicationContext.new 'springbeans_development.xml'

jruby-1.6.2 :006 > context.get_bean 'sample'

附：springbeans_development.xml

<?xml version="1.0" encoding="GB2312"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans default-autowire="byName">
  <bean id="sample" class="java.util.ArrayList">
    <constructor-arg>
      <list>
        <value>sample01</value>
        <value>sample02</value>
        <value>sample03</value>
      </list>
    </constructor-arg>
  </bean>
</beans>

搜索开源包

$ jruby -S gem list mvn:org.mortbay.jetty:jetty -r

*** REMOTE GEMS ***

mvn:org.mortbay.jetty:jetty (7.0.0.pre.5 java, 7.0.0.pre.4 java, ......)

$ jruby -S gem search mvn:org.mortbay.jetty:jetty -r

*** REMOTE GEMS ***

mvn:org.mortbay.jetty:jetty (7.0.0.pre.5 java, 7.0.0.pre.4 java,......)
