DigestUtils md5Hex 问题

Question

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

我看到了以下输出，我的期望是它对于给定的字符串是相同的，但看起来不是。这里有什么问题？

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：

The concatenated string is JaclynSmith Women'sComfortDressPumpTori-Blackhttp://www.kmart.com/jaclyn-smith-women-s-comfort-dress-pump-tori-black/p-035VA51352201P//clothing-shoes-jewelry/b-1325032682?sbf=Brand&sbv=Jaclyn+SmithProductDescriptionWhetheryourlookisdressyorcasual,addaclassictouchwiththesewomen'sToripumpsbyJaclynSmith.Theseshoesfeatureshinypatent-lookuppersandwrapped,medium-heightheels.Comfortablecushionedinsolesprovideextrasupportwhiletexturedrubberoutsolesaddanon-slipfit,makingtheseround-toepumpsperfectforeverydayofficewearoraformalnightout.Slip-ondesignSyntheticleatherupperRoundtoeCushionedinsoleTexturedrubberoutsole3-in.wrappedheelCare:WipecleanImportedif(isI18NConvReq()){$("#desca").hide();}24.99http://c.shld.net/rpx/i/s/i/spin/image/spin_prod_1001427212?hei=315&wid=315&op_sharpen=1&resMode=sharp&op_usm=0.9nullKmarthttp://www.kmart.com/jaclyn-smith-women-s-comfort-dress-pump-tori-black/p-035VA51352201P//clothing-shoes-jewelry/b-1325032682?sbf=Brand&sbv=Jaclyn+Smithnullnull

Answer 1

你的输入不一样。 spin_prod_ 之后的倒数第二个*（或百位）数字分别是 2 4 1 3。 (* 我最喜欢的很少用到的词之一。)
