对Ralasafe的三�a�两语

三刀��の逆风 — Mon, 04 Mar 2013 15:53:00 GMT

    很早以前�Q�我��想�q�实现数据��的系�l�安全组�Ӟ��可惜个�h能力有限�Q�一直未能实现�?br />    一�D�|��_��曾搜寻过国外的一些知名安全管理，��g��没找到合乎心意的�Q�就�q�大名鼎鼎的Spring出的SpringSecurity居然也没有这斚w��的实现。所谓的 RDBMS NoSQL实现�Q�是如此的不堪一试�?br />    �Ӟ��在iteye.com论坛看到�q?metadmin�Q�后来才知这��是Ralasafe的前�w�，最�l�在�?#8220;强大�?#8221;癑ֺ�下，扑ֈ�了Ralasafe(www.Ralasafe.cn)�Q�刚好是1.2�W�一版发布的时候�?
    自然�Q�下载搭建，�q�程是�O长的�?
    1.是当时居然没有默认的UTF-8的支�?汪兄既然是全球性的推广�Q��ؓ何不写多个filter�?
    2.没有MSSQL的结构，虽然改一个数据结构不是难事，毕竟很多新手又会犯很多错了�?
    3.后台控制界面什么的都有�Q�只是要嵌入已有架构中，��g��不是一件简单的事（嘿，估计是本人水�q�_��Q��?br />    之后加入了Q��，�׃��目都是很紧张的�Q�看�q�一部分代码后，一直没有再深入了�?br />
    今天在群上看到汪在跟用户谈论Ralasafe的问题，可见�C�֌�一直还没有形成互动�Q�看到实在可惜�?br />    所以就牢骚了以下一�D�话�Q?br /> --------------------------
    对于Ralasafe�Q�我惌��几句�Q�刚好汪也在�?br />    Ralasafe是一个很不错的安全组�?因�ؓ屏掉原有的组�Ӟ��那怕是功能不好的）�Q�启用Ralasafe�Q�需要的是架构能力�?br />    我刚接触到Ralasafe�Ӟ��很是�ƣ喜�Q�难得在国内有志之士可以做出�q�样好的�l��g�Q��ƈ可以开源。但布��v��试�?(期间问过一个�ؕ码问题）�Q�发现要溶入我原来的架构�Q��ƈ不理惟�?br />    而这些入侉|��的修改�Q�似乎是一直到底的�Q�很明显一点，是Ralasafe的DAO是自成体�p�R�?br />    启用一个组�Ӟ��q�多的修改（感觉接口也不��很明显�Q�，会导致不可预想的BUG�?br />    ��目大都是希望快速上�U�的�Q�而我个�h的情况，刚好公司采用FLEX做前端，修改量就更加�?
    之前我改SpringSecurity的，只去到操作��Q�数据权限还没有处理。但它的接口是很明显的，用户DAO接口�Q�提供的权限数据接口。基本我从hibernate转到nutz�Q�这��h��改DAO�Q�也��是一天半天的功夫�?br />     于是�Q�Ralasafe被我放下�?其实我也很想用�v来，但实际没有时间让我深入研�I��ƈ修改�?br />     所以我也没对Ralasafe作出什么�A献�?然后�Q�我个�h认�ؓRalasafe�Q�可提高几方面：
     1.对多数据库的支持�Q?.2不是不支持，而是没有其它数据库的布��v文�g�Q�新手就困难了）�?
     2.提炼用户登陆接口�Q�其实视图也��是个好的选择�Q�，但接口更明显�?
     3.提炼权限数据提供接口�Q�让其它的框架可以方便热拔插。（主要是DAO部分�Q��?br />     4.提炼后台�l�护的服务类和DAO操作接口�Q�这��L��户可以方便自己提供操作界面�?
--------------------------
     而��^心而论�Q�能��这么好的项目开源出来，的确要很大的勇气。我惛_��国外��是一件很了不��L��事，而国人的习惯�Q�导致很多好的东西推�q�不��h��?br />     最后希望Ralasafe可以走得更远�?
