1.百度AI识别API  
[http://ai.baidu.com/docs\#/OCR-API/top][http_ai.baidu.com_docs_OCR-API_top]  
2.登录创建应用

创建应用，获取  
AppID  
API Key  
Secret Key

3.Java项目开发  
pom.xml 加入sdk配置

<dependency>
    			<groupId>com.baidu.aip</groupId>
    			<artifactId>java-sdk</artifactId>
    			<version>4.10.0</version>
    		</dependency>

jsp原生ssm框架请下载jar包

4.新建ApiOrcUtil.java 文字识别工具类  
将下文中的APP\_ID、API\_KEY、SECRET\_KEY 替换成你申请的应用

import com.baidu.aip.ocr.AipOcr;
    import com.bdxh.framework.commons.util.ConfigMgr;
    import org.json.JSONObject;
    
    import java.util.HashMap;
    
    public class ApiOrcUtil {
    
        //设置APPID/AK/SK
        private static String APP_ID = "APP_ID";
        private static String API_KEY ="API_KEY";
        private static String SECRET_KEY = "SECRET_KEY";
    
        public static String getPictureString(String photoPath){
    
            // 初始化一个AipOcr
            AipOcr client = new AipOcr(APP_ID, API_KEY, SECRET_KEY);
    
            // 可选：设置网络连接参数
            client.setConnectionTimeoutInMillis(2000);
            client.setSocketTimeoutInMillis(60000);
    
            // 传入可选参数调用接口
            HashMap<String, String> options = new HashMap<String, String>();
            // 是否检测朝向
            options.put("detect_direction", "false");
            // 是否检测风险
            options.put("detect_risk", "false");
    
            // 正反面front /back
            String idCardSide = "front";
    
            // 参数为本地图片二进制数组
            /*byte[] file = new byte[0];
            try {
                file = Util.readFileByBytes(photoPath);
            } catch (IOException e) {
                e.printStackTrace();
            }
            JSONObject res = client.idcard(file, idCardSide, options);
            System.out.println(res.toString(2));*/
    
    
            // 参数为本地图片路径
            try {
                JSONObject res = client.idcard(photoPath, idCardSide, options);
                System.out.println(res.toString(2));
                if (res != null) {
                    JSONObject idCard = new JSONObject();
                    JSONObject words_result = res.getJSONObject("words_result");
    
                    idCard.put("name", words_result.getJSONObject("姓名").get("words"));
                    idCard.put("nation", words_result.getJSONObject("民族").get("words"));
                    idCard.put("address", words_result.getJSONObject("住址").get("words"));
                    idCard.put("sex", words_result.getJSONObject("性别").get("words"));
                    idCard.put("birth", words_result.getJSONObject("出生").get("words"));
                    idCard.put("number", words_result.getJSONObject("公民身份号码").get("words"));
                    return idCard.toString(2);
                } else {
                    return "";
                }
            }catch (JSONException e){
                e.printStackTrace();
            }
            return null;
        }
    
        public static void main(String[] args) {
            System.out.println("正面" + getPictureString("F:\\zsl\\zsl\\sfz/bbb.jpg"));
        }
    }

5.打印结果
