JsonSerialize与 JsonDeserialize使用

1、已注解方式使用

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

2、自定义实现类

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