由以下原因引起：org.springframework.cache.Cache $ ValueRetrievalException：无法使用“ com.ulisesbocchio.jasyptspringboot”加载键“ test”的值

Question

我正在开发代码 Spring Boot Jasypt 示例。在运行代码时，我看到以下错误。我参考了开发代码：https://github.com/ulisesbocchio/jasypt-spring-boot/issues/11#issuecomment-333134117。

错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'welcomeController': Injection of autowired dependencies failed; nested exception is org.springframework.cache.Cache$ValueRetrievalException: Value for key 'test' could not be loaded using 'com.ulisesbocchio.jasyptspringboot.caching.CachingDelegateEncryptablePropertySource$$Lambda$212/1832284192@1cb37ee4'

Answer 1

我遇到了完全相同的问题，这可能与您使用的springboot版本有关。在撰写本文时，springboot jasypt仅支持Springboot的2.0.x版本。

用于Spring boot 1.4.X，1.5.X和2.0.X的Jasypt集成
