maven:

>     <dependency>
>       <groupId>com.baidu.aip</groupId>
>       <artifactId>java-sdk</artifactId>
>       <version>4.12.0</version>
>     </dependency>

AipOcr对象单例：

>     public class AipOcrSingleton {
>         public static volatile AipOcr aipOcr = null;
>         //设置APPID/AK/SK
>         public static final String APP_ID = "";
>         public static final String API_KEY = "";
>         public static final String SECRET_KEY = "";
>         public static final int CONNECTION_TIME_OUT = 2000;//建立连接的超时时间（单位：毫秒）
>         public static final int SOCKET_TIME_OUT = 6000;//通过打开的连接传输数据的超时时间（单位：毫秒）
>         private AipOcrSingleton(){}
>     
>         public static AipOcr getAipOcr(){
>             if(aipOcr == null){
>                 synchronized (AipOcrSingleton.class){
>                     if(aipOcr == null){
>                         aipOcr = new AipOcr(APP_ID, API_KEY, SECRET_KEY);
>                         // 可选：设置网络连接参数
>                         aipOcr.setConnectionTimeoutInMillis(CONNECTION_TIME_OUT);
>                         aipOcr.setSocketTimeoutInMillis(SOCKET_TIME_OUT);
>                         //setHttpProxy 设置http代理服务器
>                         //setSocketProxy 设置socket代理服务器 （http和socket类型代理服务器只能二选一）
>                     }
>                 }
>             }
>             return aipOcr;
>         }
>     }

测试：

>     @Test
>         public void testAipOcr(){ //通用文字识别
>             // 初始化一个AipOcr
>             AipOcr client = AipOcrSingleton.getAipOcr();
>             // 可选：设置代理服务器地址, http和socket二选一，或者均不设置
>     //        client.setHttpProxy("proxy_host", proxy_port);  // 设置http代理
>     //        client.setSocketProxy("proxy_host", proxy_port);  // 设置socket代理
>     
>             // 传入可选参数调用接口
>             HashMap<String, String> options = new HashMap<String, String>();
>             options.put("language_type", "CHN_ENG");
>             options.put("detect_direction", "true");
>             options.put("detect_language", "true");
>             options.put("probability", "true");
>     
>             // 调用接口
>            /* String path = "C:\\Users\\Administrator\\Desktop\\IMG_0403.JPG";
>             JSONObject res = client.basicGeneral(path, options);
>             System.out.println(res.toString(2));*/
>     
>            /* // 参数为二进制数组
>             byte[] file = readFile("test.jpg");
>             res = client.basicGeneral(file, options);
>             System.out.println(res.toString(2));
>     */
>             // 通用文字识别, 图片参数为远程url图片
>             String url = "https://timgsa.baidu.com/timg?image&quality=80&size=&sec=1571819553651&di=db2f26a724a259fb93c89964b2ea9cc7&imgtype=0&src=http%3A%2F%2Fwww.ansunspd.com%2Fuploads%2Fallimg%2F110617%2F1_110617115131_1.jpg";
