Qualifier之Bean的名称首字母大写还是小写？

源码

Thus “FooBah” becomes “fooBah” and “X” becomes “x”, but “URL” stays as “URL”.
如果一个类名是以两个大写字母开头的，则首字母不变，其它情况下默认首字母变成小写。

/**
 * Utility method to take a string and convert it to normal Java variable
 * name capitalization.  This normally means converting the first
 * character from upper case to lower case, but in the (unusual) special
 * case when there is more than one character and both the first and
 * second characters are upper case, we leave it alone.
 * <p>
 * Thus "FooBah" becomes "fooBah" and "X" becomes "x", but "URL" stays
 * as "URL".
 *
 * @param  name The string to be decapitalized.
 * @return  The decapitalized version of the string.
