In the use of MP When doing database operations , The following error occurred ,

com.alibaba.excel.exception.ExcelAnalysisException: nested exception is org.apache.ibatis.reflection.ReflectionException: Could not set property 'id' of 'class com.ym.edu.entity.Subject' with value '1540878683122229249' Cause: java.lang.IllegalArgumentException: argument type mismatch

After inspection , It is found that it is a primary key policy problem ,ID_WORKER The primary key policy obtains long type , The database is of string type

    @ApiModelProperty(value = " Course category ID")
