 创建应用，获得APP_ID、API_KEY和SECRET_KEY

参考文档进行测试

import java.util.*;

import org.json.JSONObject;
import com.baidu.aip.ocr.AipOcr;

public class OCRUtils {


    //设置APPID/AK/SK
    public static final String APP_ID = "APP_ID ";
    public static final String API_KEY = "API_KEY ";
    public static final String SECRET_KEY = "SECRET_KEY ";

    private static volatile AipOcr client = null;
    final static Object lock = new Object();

    public static AipOcr getClient(String appId,String apiKey,String secretKey){

        if (client == null){
            synchronized (lock){
                if (client == null){
                    client = new AipOcr(appId, apiKey, secretKey);
                }
            }
        }
        return client;
    }



    public static void main(String[] args) {
        // 初始化一个AipOcr
        AipOcr client = getClient(APP_ID, API_KEY, SECRET_KEY);

        // 可选：设置网络连接参数
        client.setConnectionTimeoutInMillis(2000);
        client.setSocketTimeoutInMillis(60000);


        // 调用接口
        String path = "C:\\Users\\admin\\Pictures\\a.png";
        JSONObject res = client.basicGeneral(path, new HashMap<String, String>());
        System.out.println(res.toString(2));

    }

}

测试结果
