    直接上源码,这是一个收费的且不开源的库,测试效果也不太理想
    亲测效果:

    1. 对于相同字体。非倾斜的,比如http://dz.bjjtgl.gov.cn/service/checkCode.do,识别率还是挺高的;
    2. 对于斜体或者其他变异的,如下代码识别率就很低了,可能需要调整识别引擎的参数了,大家自己查找测试下。
    3. 这个测试版本的,会有弹出对话框 框框~~
    package com.example;
    
    import java.awt.image.BufferedImage;
    import java.io.File;
    import java.io.FileOutputStream;
    import java.io.IOException;
    import java.io.InputStream;
    import java.io.OutputStream;
    import java.util.Date;
    
    import javax.imageio.ImageIO;
    
    import org.apache.commons.httpclient.HttpClient;
    import org.apache.commons.httpclient.HttpStatus;
    import org.apache.commons.httpclient.methods.GetMethod;
    import org.apache.commons.io.IOUtils;
    import com.asprise.ocr.Ocr;
    
    public class ReadImg {
        public static void main(String[] args) throws IOException {
            HttpClient httpClient = new HttpClient();
            GetMethod getMethod = new GetMethod("http://dz.bjjtgl.gov.cn/service/checkCode.do");
    //      GetMethod getMethod = new GetMethod("https://dynamic.12306.cn/otsweb/passCodeAction.do?rand=sjrand");
            int statusCode = httpClient.executeMethod(getMethod);
            if (statusCode != HttpStatus.SC_OK) {
                System.err.println("Method failed: " + getMethod.getStatusLine());
                return ;
            }
            String picName = "F:\\img\\";
            File filepic=new File(picName);
            if(!filepic.exists())
                filepic.mkdir();
            File filepicF=new File(picName+new Date().getTime() + ".jpg");
            InputStream inputStream = getMethod.getResponseBodyAsStream();
            OutputStream outStream = new FileOutputStream(filepicF);
            IOUtils.copy(inputStream, outStream);
            outStream.close();
    
            Ocr.setUp(); // one time setup
            Ocr ocr = new Ocr(); // create a new OCR engine
            ocr.startEngine("eng", Ocr.SPEED_FASTEST); // English
            String s = ocr.recognize(new File[] {filepicF},Ocr.RECOGNIZE_TYPE_TEXT, Ocr.OUTPUT_FORMAT_PLAINTEXT);
            System.out.println("Result: " + s);
            System.out.println("num is:" + s.replace(",", "").replace("i", "1").replace(" ", "").replace("'", "").replace("o", "0").replace("O", "0").replace("g", "6").replace("B", "8").replace("s", "5").replace("z", "2"));
            // ocr more images here ...
            ocr.stopEngine();
        }
    }
    

    需要的java包

    注意:主要的jar包

    1. aocr.jar -- 去Asprise官网下载最新jar包
    2. commons-codec.jar
    3. commons-httpclient-3.1.jar
    4. commons-io.jar
    5. commons-logging-1.0.4.jar
