String recInspectApplicationJsonString = JSON.toJSONString(recInspectApplicationPO, SerializerFeature.WriteNullStringAsEmpty, SerializerFeature.WriteNullBooleanAsFalse);
   

 JSON.toJSONString(自定义对象, SerializerFeature.WriteNullStringAsEmpty, SerializerFeature.WriteNullBooleanAsFalse);

 

json机制内,默认将空值不转换为json内的对象;
