Google Guice�Q�一个号�U�比Spring�?00倍的IOC容器。某不才�Q�也愿意跟随大家一起学习Guice的思想�Q�如果能够在此过�E�中有所收获��p��C��我们的目的。如果能够深�ȝ��?em>IOC背后的思想�q�能熟练掌握�q�用�Q�甚臛_��Z��个更��的IOC容器那就更美好了。如果大家想学基��教程的，可以参�?strong>前面的文�?/a>�?/font>

        └─googlecode
            └─guice

其实我们可以从guice的测试用例去学习guice的用法，�q�里��׃��谈了�?/font>

首先我们�~�译guice的源码�?/font>

ant dist

我们看看生成的文件�?/font>

C:\USERS\XYLZ\BOOKS\GUICE\GUICE-2.0-SRC\BUILD
�?nbsp; classes.bar
�?nbsp; guice-2.0-src.jar
�?nbsp; guice-2.0-src.zip
�?nbsp; guice-2.0.zip
�?nbsp; guice-with-deps.jar
�?nbsp;
├─classes
�?nbsp; └─com
├─dist
�?nbsp; �?nbsp; aopalliance.jar
�?nbsp; �?nbsp; COPYING
�?nbsp; �?nbsp; guice-2.0.jar
�?nbsp; �?nbsp; guice-assistedinject-2.0-src.jar
�?nbsp; �?nbsp; guice-assistedinject-2.0.jar
�?nbsp; �?nbsp; guice-jmx-2.0-src.jar
�?nbsp; �?nbsp; guice-jmx-2.0.jar
�?nbsp; �?nbsp; guice-jndi-2.0-src.jar
�?nbsp; �?nbsp; guice-jndi-2.0.jar
�?nbsp; �?nbsp; guice-multibindings-2.0-src.jar
�?nbsp; �?nbsp; guice-multibindings-2.0.jar
�?nbsp; �?nbsp; guice-servlet-2.0-src.jar
�?nbsp; �?nbsp; guice-servlet-2.0.jar
�?nbsp; �?nbsp; guice-spring-2.0-src.jar
�?nbsp; �?nbsp; guice-spring-2.0.jar
�?nbsp; �?nbsp; guice-struts2-plugin-2.0-src.jar
�?nbsp; �?nbsp; guice-struts2-plugin-2.0.jar
�?nbsp; �?nbsp; guice-throwingproviders-2.0-src.jar
�?nbsp; �?nbsp; guice-throwingproviders-2.0.jar
�?nbsp; �?nbsp;
�?nbsp; └─javadoc
├─javadoc
├─javadoc-core
└─META-INF
MANIFEST.MF

在这里我们可以看到除了生成guice的jar包和源码外，�q�包括各个插件的jar包和源码以及javadoc文档�?/p>

�q�里需要特别说明的是guice内部使用了cglib-2.2.1-snapshot.jar和asm-3.1.jar�Q�由于这两个包非常常见，��Z��不与其他jar包依赖的�q�两个库冲突�Q�guice使用�?em>jarjar来将�q�两个库包含在guice内部的com.google.inject.internal.cglib包和com.google.inject.internal.asm包中。这个过�E�是在common.xml中的如下�D�完成的�?/p>

<taskdef name="jarjar" classname="com.tonicsystems.jarjar.JarJarTask"

classpath="${common.basedir}/lib/build/jarjar-1.0rc8.jar"/>

<jarjar jarfile="${build.dir}/${ant.project.name}-with-deps.jar">

<fileset dir="${build.dir}/classes"/>

<zipfileset src="${common.basedir}/lib/build/cglib-2.2.1-snapshot.jar"/>

<zipfileset src="${common.basedir}/lib/build/asm-3.1.jar"/>

<rule pattern="net.sf.cglib.**" result="com.google.inject.internal.cglib.@1"/>

<rule pattern="org.objectweb.asm.**" result="com.google.inject.internal.asm.@1"/>

<keep pattern="com.google.inject.**"/>

jarjar>

Guice的源码目录结构大体如�?各个包和�cȝ��介绍在后面中会具体谈�?�Q�下一节中我们开始Guice的IOC体系�?/p>
