DigestUtils md5Hex的问题

Question

我使用org.apache.commons.codec.digest.DigestUtils.md5Hex() Apache-Commons-Codec来计算连接字符串的mD5,但是我得到相同字符串的不同mD5哈希码值.

我看到以下输出,我的期望是它对于给定的字符串是相同的,但看起来不是.问题是什么？

我使用以下代码生成MD5 Hashcode,我在centos平台上.

    if (StringUtils.isNotBlank(concatenatedString)) {

        concatenatedString = StringUtils.deleteWhitespace(concatenatedString);
        //System.out.println("The concatenated string is "+concatenatedString);

        md5Hash = DigestUtils.md5Hex(concatenatedString);
        //System.out.println("The mD5 hashcode is  "+md5Hash);

    }

输出:

Answer 1

你的输入不一样.spin_prod_之后的数字的倒计时数*(或数百)数字分别为2 4 1 3.(*我最喜欢的一个用词.)
