从手册:

Types in classname, annotationtype, returntype, and argumenttype can contain
wildcards: '?' for a single character, '*' for any number of characters (but
not the package separator), '**' for any number of (any) characters, '%' for
any primitive type, '***' for any type, and '...' for any number of arguments.
