具体来说,可以使用Base64.getEncoder().encodeToString()方法将字节数组转换为Base64编码的字符串。 返回或输出Base64编码后的字符串: 最后,我们将编码后的字符串返回或输出即可。 下面是实现这一过程的Java代码示例: java import java.util.Base64; public class HexToBase64 { public static String hexToBase64...

仔细看了下,base64和hex用在二进制和字符串之间转化,看个人情况而定,都可以使用,一个字节8位,base646位转化为一个长度,hex是4位转化为一个长度,所以使用base64在数据较大时候base64字符长度较短,在存储数据库占用空间较少,个人观点哈 2017-04-04 回复 慕移动9586113 2016-10-13 同问。 0 回复 JAVA...

Base64 将每 3 个字节用 4 个 ASCII 字符表示,转换比接近于3:4。 Hex 是直接对字节进行十六进制换算,每 1 个字节需要 2 个十六进制数字来表示,转换比为1:2。 .NET Framework 中,Base64 编/解码由Convert.ToBase64String和Convert.FromBase64String提供,Codec.Base64是对其简单的封装; ...
