        rs.next();
        File file = new File("D:/1.png");
        if (!file.exists()) {
            file.createNewFile();           
          }
          outputImage = new FileOutputStream(file);                           
            Blob blob = rs.getBlob("b");   
            is = blob.getBinaryStream();           
            int size = 0;        
            while ((size = is.read(buffer)) != -1) {           
                outputImage.write(buffer, 0, size);            
            }
            System.out.println("file read success ");
    }
}

谢谢

Table 'java.pic' doesn't exist**(java.pic表格不存在)**
检查一下mysql中 java库中是否存在pic这张表
