The DOM API enables you to add dates and timestamps as scalar values and preserve them until serialization to JSON, where they are printed as string following the ISO 8601 format. If a SQL value of type date or timestamp has been added, then the is_Date and is_Timestamp functions ...
在这个例子里我们可以看到Joda的LocalDate、LocalTime、LocalDateTime都不受@JsonFormat控制。 例子2: 配置spring.jackson.serialization.write_dates_as_timestamps 添加配置: spring.jackson.serialization.write_dates_as_timestamps=false 源代码在JsonFormat2Test,结果是: 类型序列化结果反序列化结果 java.util.Date...
