      众所周知spring框架是一个非常优秀的轻量级框架工具，我们借助它可以简单的将软件各个部分割裂开以实现较低的耦合度。
那么我们在有些时候强外界发布这些软件时面临着一个选择－－是否将spring的相关包一起发布，如果全部一齐发布则可能使原本非常小巧的程式变得非常庞大；
如果不发布则可能使客户端面临程式工作环境配置的复杂程度加大，在这里主要是spring框架的下载、配置和使用。
      基于以上情况我们选择一个折衷的办法：将spring工作必须的基本类文件和相关配置文件与我们的程式一起发布出去。在这里的问题就主要是包的选择（类相互的依赖关系）和框架类的一些配置文件的选择使用。
      由于我的经历有限，在此我就将我写的一个第三方eclipse插件管理器所面临的一些问题以及获得的经验和大家分享一下。在这里我将用一个简单的spring例子作为替代说明即可。

#System environment
Ubuntu  7.10  Linux
Eclipse Platform Version:  3.3.0  + MyEclipse  6.0

      其中spring框架的加载和配置是通过MyEclipse的插件(MyEclipse-->Project Capabilities-->Add Spring ...-->Spring 2.0 Core ...)实现的。
      以下是一个简单的spring使用的程式代码：

<? xml version="1.0" encoding="UTF-8" ?>
< beans
     xmlns ="http://www.springframework.org/schema/beans"
    xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation ="http://www.springframework.org/schema/beans
 http://www.springframework.org/schema/beans/spring-beans-2.0.xsd" >
    
    
     < bean  id ="HelloWorld"  class ="springapp.hello.HelloWorld" >
         < property  name ="message" >
             < value > world </ value >
         </ property >
     </ bean >


</ beans >

 

package  springapp.hello;

 public   interface  Hello  ... {
     public  String sayHello();
}

 

package  springapp.hello;

 public   class  HelloWorld  implements  Hello ... {
     private  String message;
    
     public  HelloWorld() ... {
        message = null ;
    }
    
     public  String sayHello() ... {
         return   " Hello  " + message + " ! " ;
    }

     public  String getMessage()  ... {
         return  message;
    }

     public   void  setMessage(String message)  ... {
         this .message  =  message;
    }

}

 

package  springapp.main;

 import  org.springframework.context.ApplicationContext;
 import  org.springframework.context.support.FileSystemXmlApplicationContext;

 import  springapp.hello.Hello;

 public   class  Main  ... {

     /** */ /**
     *  @param  args
      */
     public   static   void  main(String[] args)  ... {
        ApplicationContext ctx  =   new  FileSystemXmlApplicationContext(
                 " /src/applicationContext.xml " );
        Hello h  =  (Hello)ctx.getBean( " HelloWorld " );
        System.out.println(h.sayHello());
    }

}


最后运行Main类就会显示一些信息：

2008 - 02 - 14   14 : 50 : 55 , 954  INFO
  [ org.springframework.context.support.FileSystemXmlApplicationContext ]

Hello world!

由于有个log配置文件的问题可能有些程式运行会有警告信息，这个不要紧，不再讨论范畴。
我的解决方案是：

#   For  JBoss: Avoid to setup Log4J outside  $ JBOSS_HOME / server / default / deploy / log4j . xml!
 #   For  all other servers: Comment out the Log4J listener in web . xml to activate Log4J .
log4j . rootLogger = INFO ,  stdout ,  logfile

log4j . appender . stdout = org . apache . log4j . ConsoleAppender
log4j . appender . stdout . layout = org . apache . log4j . PatternLayout
log4j . appender . stdout . layout . ConversionPattern = %d %p [%c] - %m%n

log4j . appender . logfile = org . apache . log4j . RollingFileAppender

 #  The log file's location
log4j . appender . logfile . File = springframe_log . log
log4j . appender . logfile . MaxFileSize = 512KB

 #  Keep three  backup   files .
log4j . appender . logfile . MaxBackupIndex = 3

#  Pattern to output: data  priority  [category] -message
log4j . appender . logfile . layout = org . apache . log4j . PatternLayout
log4j . appender . logfile . layout . ConversionPattern = %d %p [%c] - %m%n

      文件命名为log4j.properties然后打包jar并且导入即可。
      但是如果将这个工程导出，一般是不携带spring框架类文件的，这时在外部运行Main类就可能出现问题，一般提示是spring相关的类文件无法找到。我当时就是通过这样一些错误信息一步步补全我的spring基础类文件的，应该有相关的工具但是我没有找到。
      在这里我就将我的结果给大家：
