jackson 中JsonFormat date類型欄位的使用

標籤：one   格式   locale   mss   tuesday   design   standard   ...   simple   

為了便於date類型欄位的序列化和還原序列化，需要在資料結構的date類型的欄位上用JsonFormat註解進行註解
具體格式如下

  @JsonFormat(pattern = "yyyy-MM-dd‘T‘HH:mm:ss.SSSZ", locale = "zh", timezone = "GMT+8")

pattern 指定轉化的格式，SSSZ(S指的是微秒，Z指時區)
此處的pattern和java.text.SimpleDateFormat中的Time Patterns一致

Letter    Date or Time Component    Presentation    ExamplesG    Era designator    Text    ADy    Year    Year    1996; 96Y    Week year    Year    2009; 09M    Month in year    Month    July; Jul; 07w    Week in year    Number    27W    Week in month    Number    2D    Day in year    Number    189d    Day in month    Number    10F    Day of week in month    Number    2E    Day name in week    Text    Tuesday; Tueu    Day number of week (1 = Monday, ..., 7 = Sunday)    Number    1a    Am/pm marker    Text    PMH    Hour in day (0-23)    Number    0k    Hour in day (1-24)    Number    24K    Hour in am/pm (0-11)    Number    0h    Hour in am/pm (1-12)    Number    12m    Minute in hour    Number    30s    Second in minute    Number    55S    Millisecond    Number    978z    Time zone    General time zone    Pacific Standard Time; PST; GMT-08:00Z    Time zone    RFC 822 time zone    -0800X    Time zone    ISO 8601 time zone    -08; -0800; -08:00

具體的pattern和轉化後的date形式如下
