2019-11-16 16:53:29.651 ERROR 24132 — [nio-8080-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: Could not set property ‘id’ of ‘class com.item.DO.ClassRoomDo’ with value ‘1195625928345116673’ Cause: java.lang.IllegalArgumentException: argument type mismatch] with root cause

error analysis ：

The error prompt is not set id attribute id Self growth is no problem Then it may be inserted into the database do class mybatis-plus There is no self incrementing id

terms of settlement ：

stay do Class id Add... To the field @TableId Annotation settings type = IdType.AUTO To specify the id Self growth , Problem solving .
