Date type invalid comparison is passed in Mybits: java.util.Date and java.lang.String

An error is reported when the Date type is passed in Mybits

Caused by: java.lang.IllegalArgumentException: invalid comparison: java.util.Date and java.lang.String
When we use the Date type as a parameter to pass in, Mybatis if verification for the Date type cannot verify whether it is an empty string ( '' ), can only verify whether it is empty (null), the newTime in the mapper below is of type Date.
