1.定义类型转换器

/** * POJO属性有值是List，无值是false * * @author dujiayong * @create 2017-11-02 9:37 */public class ImagesFormater extends JsonDeserializer {    @Override    public Object deserialize(JsonParser jp, DeserializationContext context) throws IOException, JsonProcessingException {        Object object = null;        TreeNode treeNode = jp.getCodec().readTree(jp);        ObjectMapper mapper = new ObjectMapper();        String json = mapper.writeValueAsString(treeNode);        if(treeNode instanceof ArrayNode){            object = mapper.readValue(json,List.class);        }        return object;    }}

2.在特定属性上运用类型转换器

/** * 特色能力图片 */@JsonDeserialize(using = ImagesFormater.class)private List<ShopInfoImages> AbilityImages;
