Common: Use fastjson for processing, such as serialization problems if the field is null. Then @JSONField of fastjson can solve these problems very well.
//fastjson2 设置参数为null时参与序列化
@JSONField(serializeFeatures = JSONWriter.Feature.WriteMapNullValue)
private String userPhone;//fastjson 设置参数为null时参与序列化
@JSONField(serialzeFeatures = SerializerFeature.WriteMapNullValue)
private String userPhone;
