fastJson解析复杂的json字符串，经测试已经成功解析

Posted 2020-07-17 龙杉老师

要解析的json数据格式为：

HTTP/1.1 200 OK
Content-Type: text/jsv
Content-Length: length

{
	ResponseStatus: 
	{
		
	},
	Data: 
	{
		TourCopyWriterInfo: 
		{
			DefaultCopyWriter: String,
			SearchValue: String
		},
		ThemeList: 
		[
			{
				Key: String,
				Value: String,
				PoiId: String,
				IsJump: False
			}
		],
		DestinationList: 
		[
			{
				DestName: String,
				CategoryId: 0,
				SubDestList: 
				[
					{
						Key: String,
						Value: String,
						PoiId: String,
						IsJump: False
					}
				]
			}
		],
		TourProductList: 
		{
			
		}
	}
}

要解析的为Data对象中的ThemeList数组，自己写的ThemeList元素的javabean代码如下：

/**
 * Created by sqhan on 2016/5/30.
 */
public class TopTripType {
    String key;
    String value;
    String poiId;
    boolean isJump;

    public String getKey() {
        return key;
    }

    public void setKey(String key) {
        this.key = key;
    }

    public String getValue() {
        return value;
    }

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

    public String getPoiId() {
        return poiId;
    }

    public void setPoiId(String poiId) {
        this.poiId = poiId;
    }

    public boolean isJump() {
        return isJump;
    }

    public void setJump(boolean jump) {
        isJump = jump;
    }
}

解析的代码为：

//用fastjson来解析拉取到的数据，经测试已解析成功
    public List<TopTripType> parseResponseData(String responseStr) {
        List<TopTripType> result;
        try {
            JSONObject object = JSON.parseObject(responseStr);
            JSONObject data = (JSONObject) object.get("Data");
            JSONArray jsonArray = data.getJSONArray("ThemeList");
            result = JSON.parseArray(jsonArray.toJSONString(), TopTripType.class);

        } catch (Exception e) {
            result = new ArrayList<>();
            LogUtil.e(TAG, "parseResponseData()中解析json出现异常");
        }
        return result;

    }
