ma.glasnost.orika.MappingException:No converter registered for conversion from Date to LocalDateTime

背景

背景orika api转换成另一个类型的List对象，字段从Date转为LocalDateTime报错。
详细异常

ma.glasnost.orika.MappingException: No converter registered for conversion from Date to LocalDateTime, nor any ObjectFactory which can generate LocalDateTime from Date

解决方案

增加转换器。
