问人脸搜索在servlet组件中如何调用接口呢？本地类用main函数测试正常但是在组件中调用就报错？

如题，请问诸位大佬，我建立了一个Faces类，在类内的main函数测试都正常，但是在javaee的服务器组件中调用就会出现问题，会报如下错：

对于Faces类本菜鸡是这么写的： public class Faces {

public static IaiClient getConnection () {

Credential cred = new Credential("******", //SecretId

"*******"); //SecretKey

HttpProfile httpProfile = new HttpProfile();

httpProfile.setEndpoint("iai.tencentcloudapi.com");

ClientProfile clientProfile = new ClientProfile();

clientProfile.setHttpProfile(httpProfile);

IaiClient client = new IaiClient(cred, "", clientProfile);

return client;

}

public static SearchFacesResponse searchFaces(String image) {

SearchFacesResponse resp = null;

System.out.println("start");

try{

IaiClient client = getConnection();

String params = "{\"GroupIds\":[\"students\",\"teachers\"],\"Image\":\"" + image + "\"}";

SearchFacesRequest req = SearchFacesRequest.fromJsonString(params, SearchFacesRequest.class);

resp = client.SearchFaces(req);

System.out.println(SearchFacesResponse.toJsonString(resp));

} catch (TencentCloudSDKException e) {

System.out.println(e.toString());

}

return resp;

}

public static void main(String[] args) {

byte[] data = null;

try {

InputStream in = new FileInputStream("D:\\program\\testWEB\\photo\\test\\0.jpg");

data = new byte[in.available()];

in.read(data);

in.close();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

BASE64Encoder encoder = new BASE64Encoder();

String image = encoder.encode(data);

Faces.searchFaces(image);

}

}

在运行main函数的时候都是正常的、返回正确的结果，但是在服务器组件中的doGet函数里，用Faces.searchFaces(image)调用就会出错……不清楚为什么，怎么解决……哭了……

求求诸位帮忙！
