AOP 的利器：ASM 3.0 介绍(4)

ASM3.0编程框架ASM通过树这种数据结构来表示复杂的字节码结构，并利用Push模型来对树进行遍历，在遍历过程中对字节码进行修改。所谓的Push模型类似于简单的Visitor设计模式，因为需要处理字节码结构是固定的，所以不需要专门抽象出一种Vistable接口，而只需要提供Visitor接口。所谓Visitor模式和Iterator模式有点类似，它们都被用来遍历一些复杂的数据结构。Visitor相当于用户派出的代表，深入到算法内部，由算法安排访问行程。V

ExtJS笔记---Grid实现后台分页

好记性不如烂笔头，现在每次碰见问题和觉得应该记录下来的东西都会保持写博客的习惯，今后再次碰见这种问题，就不用把时间浪费了。这段时间用ExtJS用的多一点,前段时间碰见的分页问题，今天做个笔记吧。为了简单明了，此project使用的是servlet的方式，如果你使用的是struts2或者springMVC，则相应的改变成对于方式就可以了。首先在页面引入ext所不要的文件，这个自然不必多说了吧，另外为了整个项目清晰明了，EXTJS代码也最好和JSP页面（当然了

“鱼”情未了

啊~要迟到了，又要迟到了~~~偶滴30元RMB又要飞咯...不过今天的30元交的一点不让我郁闷，原因是，我的鱼儿又活过来了，哇哈哈哈！都说宠物狗与人心灵相通，这个我信。但是否所有的宠物与主人都有心灵感应这就不得而知了。事情就发生在这个不能再平凡的周一早晨。一如既往的，洗漱着装完毕，打开卧室的门，步入客厅。平时的我一定大步走向餐厅饭饭去了，今天就不知怎么特别想去关怀一下我的小金鲤鱼。这一看，就让偶心里一沉，鱼缸里怎么就剩一条了哩~~~那只最壮硕的小金鲤鱼哪去

关于按IE的后退按钮，防止IE访问缓存页面。

按照网上搜索出来的流行方式，不管是服务器代码，还是html的meta标签，通常情况是没问题的，但当使用了代理服务器的时候，按后退按钮后，还是直接显示了缓存的页面，没有重新去服务器执行action(struts).（其他浏览器都没有问题：firefox,safari,google）有高手解释下么？？测试环境，在公司内部测试，通过代理去访问apache服务器（如果直接访问apache，以下的方法是可以的）。最近考虑了另外一种方法：就是利用cookie来做文章，
