Why can't SpringMVC configure a custom type converter with the package name "converter" - mv

Question

When I use the package name converter, an error occurs
My configuration:
My configuration:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'conversionService' defined in class path resource [spring-mvc.xml]: Cannot create inner bean 'converter.MyDateConverter#67d88886' of type [converter.MyDateConverter] while setting bean property 'converters' with key [0]; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [converter.MyDateConverter] for bean with name 'converter.MyDateConverter#67d88886' defined in class path resource [spring-mvc.xml]; nested exception is java.lang.ClassNotFoundException: converter.MyDateConverter
