言我在公司产品升级中引入struts+spring+hibernate3的框架时，那时还没有引入Acegi安全系统框架，直到在最近的开发中发现了这样一个问题：Web层可以很容易地得到登录用户的userId，但业务逻辑层的接口如何获得UserId来进行方法调用的安全控制？一开始的接口设计中，有不少方法的第一个参数都是一个String类型的userId变量，但总不能每个方法都带一个userId做为参数吧？那当然不能。那么如何将userId传给业务逻辑层的接口，或者传给业务逻辑接口的前置通知类(MethodBeforeAdvice)？在Advice类获得userId后,就可以根据userId控制方法的执行权限。既然不能使用业务方法中带userId参数的笨拙办法，那么有什么其他的方法可以传递userId呢？我最初考虑由前端传递一个Session，后来又考虑开发一个Listener，但我还没来得及去尝试这些方法的时候，偶尔翻了翻买来的《Spring in Action中文版》中介绍的acegi安全系统，觉得这个安全框架既然能够实现方法级的权限控制，就一定可以解决我现在遇到的问题：我要在业务接口的Advice类中获得登录用户的身份！《Spring in Action中文版》介绍的内容比较基础，没有直接给出一个现成的范例，于是到网上狂找一气，在google上用acegi关键字搜索了10页，找到几篇好文章，最有帮助的应该是网名为“一餐三碗”的先生的一个示例，不过在看他的例子是用acegi0.8.3做的，而我那时手头已经下载了acegi1.0，于是结合acegi1.0下载包和“一餐三碗”老兄的Demo,花了一整天的时间，终于调通了一个基于acegi1.0的例子，这个例子配置了MD5加密，后台的口令验证是根据登录表单的口令进行MD5加密后，与数据库用户表中此用户的加密口令进行比较。我想大家一定很着急先知道我们如何实现在业务方法或Advice类中获得用户身份，所以我先介绍这个例子的具体实现，然后再介绍一下Acegi。第一章 环境搭建1.1 环境配置1、下载acegi：http://nchc.dl.sourceforge.net/sourceforge/acegisecurity/acegi-security-1.0.0-src.ziphttp://prdownloads.sourceforge.net/acegisecurity/acegi-security-1.0.0.zip?download下载后需要将zip文件中的jar包解压出来，放到Web应用可以找到的lib目录下。2、配置MySQL库当然也可以使用其他数据库，这里以MySql库为例，MySql安装好以后需要建几个表，大家可以从这个地址下载“一餐三碗”先生（从名字看应该是男士）提供的例子，里面有数据库表的sql文件：

%m%n7、配置业务方法的前置通知(Advice)在业务方法的前置通知类编写获取Web层用户身份的代码，在业务方法的后置通知类编写操作日志的方法调用，在操作日志方法中可通过acegi提供的API来获取当前操作者的Authenticaton。实际上acegi提供了一个非常松散的集成机制，如果你仅需要使用acegi获得Web层的身份，只需要在Advice类中引入acegi的方法，即使我们以后不使用acegi，也使代码的修改非常有限。业务接口:TestAOPInterface。下面是为TestAOPInterface的Advice配置的xml文件aoptest.xml。
