 我不确定这是否是答案，但您需要先将响应信息设置为新类。 我用Gson库： 
 
    Gson gson = new Gson();
    HttpResponse response = httpGetRequest("URL_ENDPOINT");
    ResponseDTO responseDTO = gson.fromJson(prettyJsonResponse(response), 
    ResponseDTO.class);
 
 这是http get请求方法： 
 
    private HttpResponse httpGetRequest(String url) throws Exception {
    HttpClient client = new DefaultHttpClient();
    HttpGet request = new HttpGet(url);
    return client.execute(request);
}
 
 这是maven依赖： 
 
    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.5.2</version>
    </dependency>
 
 prettyJsonResponse方法： 
 
    private String prettyJsonResponse(HttpResponse response) throws IOException{
    StringBuffer result = new StringBuffer();
    String line = "";
    BufferedReader rd = new BufferedReader(
            new InputStreamReader(response.getEntity().getContent()));
    while ((line = rd.readLine()) != null) {
        result.append(line);
    }   
    return result.toString();
}

I am not sure if this is the answer, but you need set the response info to new class first. I use Gson library:
 
    Gson gson = new Gson();
    HttpResponse response = httpGetRequest("URL_ENDPOINT");
    ResponseDTO responseDTO = gson.fromJson(prettyJsonResponse(response), 
    ResponseDTO.class);
 
This is the http get request method:
 
    private HttpResponse httpGetRequest(String url) throws Exception {
    HttpClient client = new DefaultHttpClient();
    HttpGet request = new HttpGet(url);
    return client.execute(request);
}
 
This is the maven dependency:
 
    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.5.2</version>
    </dependency>
 
prettyJsonResponse method:
 
    private String prettyJsonResponse(HttpResponse response) throws IOException{
    StringBuffer result = new StringBuffer();
    String line = "";
    BufferedReader rd = new BufferedReader(
            new InputStreamReader(response.getEntity().getContent()));
    while ((line = rd.readLine()) != null) {
        result.append(line);
    }   
    return result.toString();
}
