很久没有更新这个blog了，因为最近在整理hibernate笔记，还有点小得意，哈哈，这是用思维导图记的笔记，后缀名应该是xmind
写这篇东西其实是因为工作的关系。学习过一些xp的思想，学习过scrum, 但是研究的都不深刻。写的基本都是自己的想法和理解，所以一定有片面或者偏激的地方。但俺就是不爱抄别人的观点。写了老半天，发给老板居然连个comment都没有，没那么差吧？下面隐去了公司的名字。 I mapped agile manifesto with the 12 principles based on my unders
不确定“再见理想”是“再见了，理想”还是“再次燃起理想”，稀里糊涂地对这句话有感觉。作为程序员，总会有自己的技术价值观和技术理想。工作七年多，开始痒了。 程序员的生活总是喜忧参半，出入体面的写字楼，在小小的cubicle里虐杀脑细胞；偶尔有条件小资一下，常被工作、生活压力逼得点灯熬油；有时候想，这么辛苦，不论做什么行业都会做
struts-default.xml, struts-plugin.xml, struts.xml按照顺序加载，因为多个plugin的加载顺序不一定，所以plugin之间不能有依赖关系 因为struts的action是多实例的，所以跟spring集成的时候要求prototype scope. hibernate transient 和 detached的区别在于

Struts 2 solves this problem by creating a new instance of an action for each request that maps to it. namespace: <package name="chapterThreeSecure" namespace="/chapterThree/secur
众多软件大师中，最仰慕的就是Martin Fowler. 就在一个月之前, 在敏捷中国大会上有幸见到偶像，还攀谈几句，呵呵，开心。喜欢Fowler是因为他深邃的思想，洞察本质的机敏。如果我有他的思想，该能迷倒多少女程序员啊。Martin Fowler在大会上主要谈以人为本, adaptive plan 以及continuous integration/release. 按照我对agile的理解，我

今天跟老婆学郭德纲的一个小段“刘关张兄弟三人桃园结义,一个头磕完那就跟亲兄弟一样！然后保着唐僧就上了梁山了~《红楼梦》里有这个故事”。讲完老婆问，这个笑话里怎么没提聊斋志异？我说这说的是四大名著啊，老婆问，四大名著里没有聊斋志异么？我靠，活见鬼了，聊斋来啦…这就是俺婆娘，当年林大信息专业成绩第一啊。 想起来还有一次，电视里说“这不是关公战秦琼么？”正好那段时间老婆每天跑步的时候听三国演义。她听电
