the class FileCopier method copy.

/**
 * 执行拷贝<br>
 * 拷贝规则为：
 * <pre>
 * 1、源为文件，目标为已存在目录，则拷贝到目录下，文件名不变
 * 2、源为文件，目标为不存在路径，则目标以文件对待（自动创建父级目录）比如：/dest/aaa，如果aaa不存在，则aaa被当作文件名
 * 3、源为文件，目标是一个已存在的文件，则当{@link #setOverride(boolean)}设为true时会被覆盖，默认不覆盖
 * 4、源为目录，目标为已存在目录，当{@link #setCopyContentIfDir(boolean)}为true时，只拷贝目录中的内容到目标目录中，否则整个源目录连同其目录拷贝到目标目录中
 * 5、源为目录，目标为不存在路径，则自动创建目标为新目录，然后按照规则4复制
 * 6、源为目录，目标为文件，抛出IO异常
 * 7、源路径和目标路径相同时，抛出IO异常
 * </pre>
