问反序列化问题

EN

我试图从Nutritionix反序列化JSON响应。当我试图反序列化对象时，我一直得到一个HTTP 500 --请求处理失败；嵌套的异常是java.lang.ClassCastException: java.lang.String不能转换为java.util.Map错误。我非常困惑，也不知道为什么这会不断发生，因为is似乎得到了一个有效的JSON响应，但我不确定。

public class CallSearch {

    String value;

    public CallSearch(String search){
        value = search.replace(" ", "%20");
    }
    public FullResponse search() throws ClientProtocolException, IOException{

        CloseableHttpClient client = HttpClients.createDefault();
        HttpGet getProducts = new HttpGet("https://api.nutritionix.com/v1_1/search/"+ value +"?results=0%3A6&cal_min=0&cal_max=50000&fields=item_name%2Citem_id&appId=ac23ceb3&appKey=e2b579c55b4857157fc6045d6296b532");
        CloseableHttpResponse productResponse = client.execute(getProducts);
        String entityString = EntityUtils.toString(productResponse.getEntity());
        FullResponse test = new JSONDeserializer<FullResponse>().deserialize(entityString,FullResponse.class);

        return test;
    }
}

我创建的反序列化类如下所示

public class FullResponse {

    String total_hits;
    String max_score;
    List<Hits> hits;

    public FullResponse(){

    }

    public String getTotal_hits() {
        return total_hits;
    }

    public void setTotal_hits(String total_hits) {
        this.total_hits = total_hits;
    }

    public String getMax_score() {
        return max_score;
    }

    public void setMax_score(String max_score) {
        this.max_score = max_score;
    }

    public List<Hits> getHits() {
        return hits;
    }

    public void setHits(List<Hits> hits) {
        this.hits = hits;
    }

Hits类，它是完整响应中的列表

public class Hits {

       String _index;
       String _type;
       String _id;
       String _score;
       List<Fields> fields;

       public Hits(){

       }

        public String get_index() {
        return _index;
    }

    public void set_index(String _index) {
        this._index = _index;
    }

    public String get_type() {
        return _type;
    }

    public void set_type(String _type) {
        this._type = _type;
    }

    public String get_id() {
        return _id;
    }

    public void set_id(String _id) {
        this._id = _id;
    }

    public String get_score() {
        return _score;
    }

    public void set_score(String _score) {
        this._score = _score;
    }

    public List<Fields> getFields() {
        return fields;
    }

    public void setFields(List<Fields> fields) {
        this.fields = fields;
    }
}

最后是Field类：

public class Fields {

    String item_name;

    public Fields(){

    }

    public String getField(){
        return item_name;
    }
    public void setField(String name){
        item_name=name;
    }
}

对我可能出错的地方有任何帮助，我将不胜感激。谢谢

好的，我做了修改，下面是我得到的JSON响应

{ "total_hits":11025，"max_score":11.122117，“点击”：{"_index":"nixproductionv13"，“_type”：“项目”，"_id":"513fceb375b8dbbc210000e4"，"_score":11.122117，“字段”：{“item_name”：“整体牛奶-1 tbsp"}}，{ "_index":"nixproductionv13"，”_type“：”项目“，”_id“：”513fceb375b8b8dbb2100017b“，”_score“：”_score“：10.703835，“字段”：{“item_name”：“2%牛奶-1杯”}，{"_index":"nixproductionv13"，“_type”：“项目”，"_id":"513fceb375b8dbbc210000f3"，"_score":10.7038355，“字段”：{“item_name”：“1%牛奶-1杯”}，{"_index":"nixproductionv13"，“_type”：“项目”，“_id”：“513fceb375b8b8b8bbc210000fb”，"_score":10.689078，“字段”：{“item_name”：“浏览牛奶-1杯”}，{"_index":"nixproductionv13"，“_type”：“项目”，"_id":"513fceb375b8dbbc210000e3"，"_score":10.65872，“字段”：{“item_name”：“整体牛奶-1 fl oz"}}，{"_index":"nixproductionv13"，”_type“：”项目“，”_id“：”513fceb375b8b8b8dbbc2100017a“，"_score":10.392，“字段”：{“item_name”：“2%牛奶-1夸脱”}}

它现在导致嵌套的异常是java.lang.IllegalArgumentException:参数类型不匹配
