本文介绍了Mapstruct LocalDateTime到即时的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我是Mapstruct的新手。我有一个包含 LocalDateTime 类型字段的模型对象。 DTO包含 Instant 类型字段。我想将 LocalDateTime 类型字段映射到 Instant 类型字段。我有 TimeZone 传入请求的实例。I am new in Mapstruct. I have a model object which includes LocalDateTime type field. DTO includes Instant type field. I want to map LocalDateTime type field to Instant type field. I have TimeZone instance of incoming requests.像这样手动设置字段；Manually field setting like that;set( LocalDateTime.ofInstant(x.getStartDate(), timeZone.toZoneId()) )如何使用Mapstruct映射这些字段？How can I map these fields using with Mapstruct?推荐答案您有2种选择来实现第一个选项：使用新的 @Context timeZone 属性的1.2.0.Final版本中的/ code>批注，并定义您自己的执行映射的方法。Use the new @Context annotation from 1.2.0.Final for the timeZone property and define your own method that would perform the mapping. Something like:public interface MyMapper { @Mapping(target = "start", source = "startDate") Target map(Source source, @Context TimeZone timeZone); default LocalDateTime fromInstant(Instant instant, @Context TimeZone timeZone) { return instant == null ? null : LocalDateTime.ofInstant(instant, timeZone.toZoneId()); }}然后，MapStruct将使用提供的方法在即时和 LocalDateTime 。MapStruct will then use the provided method to perform mapping between Instant and LocalDateTime.第二个选项：public interface MyMapper { @Mapping(target = "start", expression = "java(LocalDateTime.ofInstant(source.getStartDate(), timezone.toZoneId()))") Target map(Source source, TimeZone timeZone);}我个人的选择是使用第一个My personal option would be to use the first one 这篇关于Mapstruct LocalDateTime到即时的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
