时间格式转换、Cannot deserialize value of type `java.util.Date` from String "2020-01-01"

 

 

 

 

error: Failed to parse Date value ‘2020-01-01’: Unparseable date: “2020-01-01”); nested exception is com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type java.util.Date from String “2020-01-01”

1.服务器用@RequestBody接收数据，前端传的格式是yyyy-MM-dd。
2.异常描述：反序列化失败，yyyy-MM-dd不是有效的格式。

解决方案

方案1：添加@JsonFormat注释，pattern格式要与前端一致

 

@JsonFormat和@DateTimeFormat
