"^SDPCDR.*\\d{8}.*\\.asn$"

Pretty generous on the date part, but the string is probably specific enough already to avoid false matches. 日期部分相当宽泛，但是字符串可能已经足够具体，可以避免错误匹配。 If you're looking for a substring rather than trying to match the entire string, instead use 如果您要查找子字符串而不是尝试匹配整个字符串，请使用 

"SDPCDR.*?\\d{8}.*?\\.asn"
