1.直接改成字符串
2.加注解
//向前端返回时将Long转成字符串 public class LongJsonSerializer extends JsonSerializer<Long> { @Override public void serialize(Long value, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException, JsonProcessingException { String text = (value == null ? null : String.valueOf(value)); if (text != null) { jsonGenerator.writeString(text); } } ———————————————— 版权声明:本文为CSDN博主「ht_kasi」的原创文章,遵循 CC 4.0 BY-SA 版权协议,转载请附上原文出处链接及本声明。 原文链接:https://blog.csdn.net/ht_kasi/article/details/81230234
//将接收的前端字符串类型转换成Long类型 public class LongJsonDeserializer extends JsonDeserializer<Long> { private static final Logger logger = LoggerFactory.getLogger(LongJsonDeserializer.class); @Override public Long deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException { String value = jsonParser.getText(); try { return value == null ? null : Long.parseLong(value); } catch (NumberFormatException e) { logger.error("数据转换异常", e); return null; } } } ———————————————— 版权声明:本文为CSDN博主「ht_kasi」的原创文章,遵循 CC 4.0 BY-SA 版权协议,转载请附上原文出处链接及本声明。 原文链接:https://blog.csdn.net/ht_kasi/article/details/81230234
字段上加注解
@JsonDeserialize(using = LongJsonDeserializer.class) @JsonSerialize(using = LongJsonSerializer.class) private Long id;
