详细错误如下:
com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type `java.time.LocalDateTime` from String "2020-08-11 11:00:00": Failed to deserialize java.time.LocalDateTime: (java.time.format.DateTimeParseException) Text '2020-08-11 11:00:00' could not be parsed at index 10
这是因为用了 JavaTimeModule()
作为 localDate
和 localDateTime
的解析工具,但是对于日期和时间格式我们没有指定,所以会使用默认的格式,也就是:DateTimeFormatter.ISO_LOCAL_DATE_TIME
,就是类似这样的:2011-12-03T10:15:30
。
假设我们自己用的格式是2020-08-11 11:00:00
,就需要手动配置格式:
JavaTimeModule javaTimeModule = new JavaTimeModule();
DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
javaTimeModule.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(dateTimeFormatter));
objectMapper.registerModule(javaTimeModule);
objectMapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
