Spring Boot集成Jasypt异常DecryptionException

Posted 2021-10-20 程序新视界

在Spring Boot项目中对Jasypt进行集成，当生成密码之后，启动程序抛如下异常：

com.ulisesbocchio.jasyptspringboot.exception.DecryptionException: Unable to decrypt。

完整异常信息如下：

针对此问题，原有可能有三个：

• 第一，的确是密码错误，也就是生成的密码由于不完整等原因，导致无法解密。此时重新生成密码，再试一试；
• 第二，加密算法问题，比如不同版本的Jasypt的加密算法是有所区别的，默认采用的加密算法与你生成密码的加密算法是否一致。如果不一致，那肯定无法进行解密；
• 第三，JDK没有安装不限长度的JCE版本（Unlimited Strength Java Cryptography Extension）。这种情况需要检查一下本地$JAVA_HOME/jre/lib/security目录下是否包含local_policy.jar和US_export_policy.jar量个jar包。如果没有，则进行添加。

第三种情况，所需的jar包可通过Oracle官网进行下载，下载地址：http://blog.didispace.com/spring-boot-learning-2x/
