好久不来iteye,今天又来看看，哈哈,今天碰到在编码时，反射中会抛出
Illegal overloaded getter method with ambiguous type for propert这么个东东，从字面意思看，是反射在获取getter时迷惑了，然后回想起java在boolean值在生成getter时，分别有is和getter，也许我们的反射对象中就有is开头的方法迷惑了jdk，
泛型
在Java SE 1.5之前，没有泛型的情况的下，通过对类型Object的引用来实现参数的“任意化”，任意化的缺点就是要实行强制转换，这种强制转换可能会带来不安全的隐患
泛型的特点：消除强制转换 确保类型安全 向后兼容
简单泛型的定义：
泛型：就是在类中将其模糊化，在创建对象的时候再具体定义

安装lua_nginx_module 模块
lua_nginx_module 可以一步步的安装，也可以直接用淘宝的OpenResty
Centos和debian的安装就简单了。。
这里说下freebsd的安装：
fetch http://www.lua.org/ftp/lua-5.1.4.tar.gz
tar zxvf lua-5.1.4.tar.gz
cd lua-5.1.4

* use recursion

var tt = document.getElementById("tt");
var childNodes = tt.childNodes[0].childNodes;
var level = 0;
for (var i = 0; i < childNodes.length; i++) {
