springboot项目启动时报错

java.lang.IllegalArgumentException: Failed to decrypt

指的是解密失败，原因是在数据库连接配置的地方，设置了加密

datasource:
  druid:
    #drudriver-class-name: com.p6spy.engine.spy.P6SpyDriver
    username: root
    password: root
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://192.168.2.63:6666/dy-hhd?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8&nullCatalogMeansCurrent=true
    filters: config
    connectionProperties: config.decrypt=true

解决方法

把 connectionProperties: config.decrypt=true 改为

connectionProperties: config.decrypt=false
