使用Jackson解析器进行解析

我刚刚开始使用Jackson图书馆，但我不知道如何解析我的数据。有人可以帮忙吗？

这是我的json响应...

{"flag":"1",
"data":[{"categoty_id":"150","category_name":"Baby &Kids"},{"categoty_id":"151","category_name":"Books & Comics"},{"categoty_id":"152","category_name":"Collectibles & Antiques"},{"categoty_id":"153","category_name":"Electronics"} ...and so on

为了解析数据，我正在使用以下

 try {
                            ArrayList<NameValuePair> parameters = new ArrayList<NameValuePair>();
                            parameters.add(new NameValuePair("store_id", "1"));

                            Log.e("Cat", "start querying...");
                            final String response = GetResponse.execPostScript("category.php?store_id=1");
                            Log.e("Cat",response);

                            JsonFactory jsonFactory = new JsonFactory();
                            JsonParser jsonParser = jsonFactory.createParser(response);
                            allCategory = new ObjectMapper().readValue(jsonParser, AllCategory.class);



                        } catch (Exception e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                            pD.dismiss();

                        }

我的ProJo课是生活跟随

        this.data = data;
    }

    @JsonProperty("flag")
    public void setFlag(String flag) {
        this.flag = flag;
    }

    /**

    @JsonProperty("data")
    public List<Category> getData() {
        return data;
    }

    /**

    public void setData(List<Category> data) {
        this.data = data;
    }

    @JsonAnyGetter
    public Map<String, Object> getAdditionalProperties() {
        return this.additionalProperties;
    }

    @JsonAnySetter
    public void setAdditionalProperty(String name, Object value) {
        this.additionalProperties.put(name, value);
    }

}

我正在跟踪运行时错误........

com.fasterxml.jackson.databind.JsonMappingException：无法从START_ARRAY令牌中反序列化com.elsner.bean.AllCategory的实例

但是我在解析数据时遇到错误。
