前些天發現了一個巨牛的人工智能學習網站，通俗易懂，風趣幽默，忍不住分享一下給大家。點擊跳轉到教程。

1、以注解方式使用：

@JsonDeserialize(using= DateJsonDeserializer.class)
@JsonSerialize(using= DateJsonSerializer.class)
private Date time;

2、自定義實現類：?

public class DateJsonDeserializer extends JsonDeserializer<Date>
{public static final SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");@Overridepublic Date deserialize(com.fasterxml.jackson.core.JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, com.fasterxml.jackson.core.JsonProcessingException {try{if(jsonParser!=null&&StringUtils.isNotEmpty(jsonParser.getText())){return format.parse(jsonParser.getText());}else {return null;}}catch(Exception e){System.out.println(e.getMessage());throw new RuntimeException(e);}}
}

public class DateJsonSerializer extends JsonSerializer<Date> {public static final SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");@Overridepublic void serialize(Date date, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException {jsonGenerator.writeString(format.format(date));}
