  前几天分享了一篇《Spring Boot 2.x基础教程:加密配置中的敏感信息》 (blog.didispace/spring-boot-learning-2-1-5/),然后看到群里有小伙伴反应跟着这篇文章出现了这个异常com.ulisesbocchio.jasyptspringboot.exception.DecryptionException: Unable to decrypt。

  具体完整的错误信息如下:

  Caused by: com.ulisesbocchio.jasyptspringboot.exception.DecryptionException: Unable to decrypt: ENC(/AL9nJENCYCh9Pfzdf2xLPsqOZ6HwNgQ3AnMybFAMeOM5GphZlOK6PxzozwtCm+Q). Decryption of Properties failed, make sure encryption/decryption passwords match

  直接根据错误信息的描述来判断,就是解密失败了。

  下面整理一下可能产生解密失败的几种可能:

  第一种:推测解密失败的原因是加密和解密使用的密钥不一致,也就是jasypt.encryptor.password的配置和使用插件时候的参数传的不同。

  第二种:没有安装不限长度的JCE版本(Unlimited Strength Java Cryptography Extension)。因为DD以前在用Spring Cloud Config的时候已经装过了,所以在写之前这个游戏卖号案例的时候没有提到这点,应该一些还没有接触Spring Cloud的读者通常都是这个原因导致。其实这个在之前的《分布式配置中心(加密解密)》(blog.didispace/spring-cloud-starter-dalston-3-2/) 一文中提过,但因为不属于一个系列内容,这里所以再提一下。

  我们可以从Oracle的官方网站中下载你所用Java版本对应的JCE安装包,比如:JCE8下载地址(oracle/java/technologies/javase-jce8-downloads.html)。它是一个压缩包,解压后可以看到下面三个文件:

  README.txt

  local_policy.jar

  US_export_policy.jar

  我们需要将local_policy.jar和US_export_policy.jar两个文件复制到$JAVA_HOME/jre/lib/security目录下,覆盖原来的默认内容,这样加密解密的准备工作就完成了。
