想要将此JSON转换为要与杰克逊一起映射的POJO

Answer 1

要从字符串jsonSource反序列化给定的json，请使用类似

的内容

ObjectMapper mapper = new ObjectMapper();
Root root = mapper.readValue(jsonSource, Root.class);

我为你生成了POJO

import java.util.HashMap;

class Root {
    private HashMap<String, Value> statValues = new HashMap<>();

    public HashMap<String, Value> getStatValues() {
        return statValues;
    }

    public void setStatValues(HashMap<String, Value> statValues) {
        this.statValues = statValues;
    }
}

class Value {
    double value;

    public double getValue() {
        return value;
    }

    public void setValue(double value) {
        this.value = value;
    }
}

如果能够提供更好的名称，可以使用@JsonProperty

重新映射属性

要访问价值，请使用root.get("c__TL_gattooi").getValue()之类的内容来获取密钥列表 - root.keys()

JSON到对象映射
