本文探讨了如何修复Jackson在处理前端传来的2021-04-16T02:07:21.729Z格式日期时的InvalidFormatException。问题在于后端期望yyyy-MM-dd格式，需在Date字段上添加@JsonFormat注解。通过添加格式化注解，解决了数据转换问题。

com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type java.util.Date from String “2021-04-16T02:07:21.729Z”: not a valid representation (error: Failed to parse Date value ‘2021-04-16T02:07:21.729Z’: Unparseable date: “2021-04-16T02:07:21.729Z”)

前台时间类型 2021-04-16T02:07:21.729Z
后端 date 需要加注解 @JsonFormat(pattern=“yyyy-MM-dd”)

com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type `java.util.Date` from String "2021-04-16T02:07:21.729Z": not a valid representation (error: Failed to parse Date value '2021-04-16T02:07:21.729Z': Unparseable date: "2021-04-16T02:07:21.729Z")
