编辑：在添加最新的attributeconverter代码之前，此应用程序可以正常启动和运行。我怀疑是因为自动布线的缘故。因为如果我从属性转换器中删除autowiredbean，应用程序就可以正常启动。
编辑：密码创建者代码，secretkey
我尝试在将值持久化到数据库时使用加密。我实现了一个属性转换器类和另一个用于初始化密码以及为密钥注入配置值的类。
当我用attributeconverter装饰实体类进行加密时，框架不会完成启动。
它在==>触发spring数据存储库的延迟初始化之后停止。它不会抛出任何异常来停止。就坐在那里。如果我从密码创建者中删除自动连线注解，它将启动。

我注意到如果我不使用

[@]Autowired
    CipherCreator cipherCreator;

应用程序启动。
有什么想法都可以
