idea日志问题:application.yml 写debug打印日志报错问题
日志报错,提示:
***************************
APPLICATION FAILED TO START
***************************
Description:
Failed to bind properties under 'logging.level' to java.util.Map<java.lang.String, org.springframework.boot.logging.LogLevel>:
Reason: No converter found capable of converting from type [java.lang.String] to type [java.util.Map<java.lang.String, org.springframework.boot.logging.LogLevel>]
Action:
Update your application's configuration
原因:
yml文件中的格式不对,冒号后面要空一格再来写属性值
正确写法:
logging: (顶头)
level: (空两格)
cn.zzlr: debug ((空两格)键:(空一格)值)
注意: logging.level(回车键:代码会自动补全的)
logging:
level: debug(这是字符串,所以抛异常)
logging:
level:
cn.zzlr: debug
level是map键值对形式
(key:包名)cn.zzlr: debug(值:是级名)
