JSON parse error: Cannot deserialize value of type `java.time.LocalDateTime` from String

今天用API接口测试SpringBoot项目遇到这样的错误：

JSON parse error: Cannot deserialize value of type `java.time.LocalDateTime` from String "2019-09-25 05:43:00": Failed to deserialize java.time.LocalDateTime: (java.time.format.DateTimeParseException) Text '2019-09-25 05:43:00' could not be parsed at index 10; nested exception is com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type `java.time.LocalDateTime` from String "2019-09-25 05:43:00": Failed to deserialize java.time.LocalDateTime: (java.time.format.DateTimeParseException) Text '2019-09-25 05:43:00' could not be parsed at index 10

后来查了一下原因，记录一下

原因是实体类中参数类型为LocalDateTime, 但是Postman测试的json格式的数据是String字符串。

只需要在接收参数实体类的日期字段上添加JsonFormat注解即可

补充个内容：
@JsonFormat(pattern = “yyyy-MM-dd HH:mm:ss” timezone = “GMT+8”）
转化时区差

字符串类型直接转换成Date

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String str = sdf.format(new Date());
