通用的工具类 BaseCommonUtil
通用的工具类，方法很多，另外啊 Apache Commons 也有很多。
BaseCommonUtil 主要包含：1.获取绝对根路径
2.获取项目绝对根路径
3.将路径中包含的空格转换成 "%20"
4.URL路径转码(去除空格及中文编码处理)
5.根据属性名称，向该属性中添加值（自动获取字段的属性类型，并做相应的转换）-这个其实可以用开源的beanUtil
6.判断文件是否存在
7.创建文件上传路径
8.计算转换的总时间
9.替换 \ 为 /
10.判断字符串数组中是否包含某字符串元素
11.字符转换编码实现
12.通过文件路径获取文件的扩展名
13.创建bat文件
14. 执行BAT文件
15.删除空目录
16.递归删除目录下的所有文件及子目录下所有文件
17.获取某个文件夹下的所有文件
18.查询某个文件夹下的所有文件包括子目录
19.字符串处理说明：方法不一定是最优化的，凑合着看，或者拿过去改造都可以的。
