【教程】模拟登陆百度之Java代码版

【背景】

之前已经写了教程，分析模拟登陆百度的逻辑：

【教程】手把手教你如何利用工具(IE9的F12)去分析模拟登陆网站(百度首页)的内部逻辑过程

然后又去用不同的语言：

Python的：

【教程】模拟登陆网站之 Python版（内含两种版本的完整的可运行的代码）

C#的：

【教程】模拟登陆网站之 C#版（内含两种版本的完整的可运行的代码）

去实现对应逻辑。

此处，继续尝试，用Java代码，实现这套，模拟登陆百度，的逻辑。

【折腾过程】

1.之前已经整理了一些Java代码：

http://code.google.com/p/crifanlib/source/browse/trunk/java/crifanLib.java

现在是：

继续去丰富此套库。

然后把模拟登陆百度的逻辑模拟出来。

2.期间，想要实现Java的函数的默认参数，结果却发现不支持：

【已解决】Java中函数的默认参数

3.然后就是一点点去写代码，去调试了。

4.期间，出错了：

【基本解决】java中没法new：Cannot instantiate the type HttpParams

5.再去搞懂参数配置：

【整理】关于Java中的httpClient中可以传入的参数

6.再继续写代码，期间遇到各种问题，基本都解决了：

【已解决】Java代码中new List时出错：Cannot instantiate the type List<NameValuePair>

【已解决】实现Java中控制台中输入字符串

【无需解决】Java代码new BasicNameValuePair时出错：The constructor BasicNameValuePair(String, boolean) is undefined

【已解决】Java中实现{String, boolean}类型的字典Dict变量

【已解决】Eclipse中用java代码去new Date结果出错：The constructor Date(String) is deprecated

【暂未解决】Eclipse中调试Java代码期间如何修改值

【已解决】Java中的new Date所得的年份异常：传入2043年结果却是3943年

7.最终，完成了，主体代码为：
