jasypt导致SpringBoot启动阻塞

环境

• jasypt-spring-boot-starter：2.1.0
• spring-boot：2.2.2.RELEASE

问题

• 项目启动中阻塞在下面的日志处

结论

• 通过对ConcurrentHashMap中transfer源码查看，主要出现在fh >= 0这一行，直接原因是使用了computeIfAbsent，并且传入的mappingFunction中对同一个key多次的computeIfAbsent

解决

• 升级jasypt-spring-boot-starter版本到3.0.0
• 原本的jasypt-spring-boot-starter2.1.0版本没有ivGeneratorClassname属性，但3.0.0默认使用了org.jasypt.iv.RandomIVGenerator，导致不兼容，需要单独配置ivGeneratorClassname: org.jasypt.iv.NoIvGenerator
