When using mybatis plus3.2.0 + springboot2.1.1, an error is reported
error attaching to get column from result set
1. Generally, this kind of problem occurs. The simplest error may be that the field type of the database is inconsistent with the type of the entity class
2. But I’m not. I use @ builder in the entity class, but I don’t use @ allargsconstructor and @ noargsconstructor, There is no parameterless constructor
