方式1,使用Integer

Integer.parseInt(str, 16)

如:

int baiduId = Integer.parseInt(tBaiduQid, 16);

方式2, 使用Long

Long.parseLong(tBaiduQid, 16)

如:

long baiduId = Long.parseLong(tBaiduQid, 16);

如果16进制数过大, 转10进制会报错, 则需要使用BigInteger来解决.

方式3, 使用BigInteger

import java.math.BigInteger;
BigInteger bigInteger = new BigInteger(tBaiduQid, 16);
