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
{
	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 {
	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));
	}
}
