spring boot 启动错误：Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘idUtil’: Unsatisfied dependency expressed through field ‘snowflake’; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘cn.hutool.core.lang.Snowflake’ available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: \{@org.springframework.beans.factory.annotation.Autowired(required=true)\}

具体错误如下：

Description:
    
    Field snowflake in com.mall.pro.common.util.IdUtil required a bean of type 'cn.hutool.core.lang.Snowflake' that could not be found.
    
    The injection point has the following annotations:
    	- @org.springframework.beans.factory.annotation.Autowired(required=true)
    
    
    Action:
    
    Consider defining a bean of type 'cn.hutool.core.lang.Snowflake' in your configuration.

有了犯错经验，敏锐的嗅觉告诉我是缺少了配置文件，找了大半天，才找到学习项目得配置文件ApiBeanConfig，和报错信息 **‘cn.hutool.core.lang.Snowflake’** 没点关联，配置文件取名不直观，以至于找了半天没找到

总结：配置文件名称还是要有点讲究，尽量和配置项目关键字有点联系，这样才好识别，报错的时候好找问题！
