一旦我们获取了图片对象,我们可以将其转换为byte数组。下面是一个示例代码,演示了如何将BufferedImage对象转换为byte数组: AI检测代码解析 importjava.awt.image.BufferedImage;importjava.io.ByteArrayOutputStream;importjava.io.IOException;publicclassImageUtils{publicstaticbyte[]imageToBytes(BufferedImageimage){try{By...
byte[] buff =newbyte[1024]; intlen =0; while((len = fis.read(buff)) != -1) { bos.write(buff,0, len); } // 得到图片的字节数组 byte[] result = bos.toByteArray(); // 将数组转为字符串 BASE64Encoder encoder =newBASE64Encoder(); ...
convert.run(op); } catch (IM4JavaException e) { // FIXME Auto-generated catch block e.printStackTrace(); } Stream.close(); return fos.toByteArray(); } 这样我们就把这个图片的字节流放到了数据库中 3、再来,我们就来显示这张图片
//convert BufferedImage to byte array baos = new ByteArrayOutputStream(); ImageIO.write( image, "jpg", baos); baos.flush(); return baos.toByteArray(); } catch (Exception e) { } finally { if(baos != null) { try { baos.close(); ...
在JAVA中,将附件对象转换为ByteArray可以通过以下步骤实现: 1. 首先,需要使用Java的文件处理类来读取附件文件。可以使用`FileInputStream`类来读取文件内容。例如,假设...
通过toByteArray()方法获取ByteArrayOutputStream对象中的字节数组。 以下是一个示例代码: 代码语言:txt 复制 import java.io.ByteArrayOutputStream; import java.io.InputStream; import java.net.URL; public class ImageUtils { public static byte[] convertImageToByteArray(String imageUrl) { try { URL url...
This class implements an output stream in which the data is written into a byte array. The buffer automatically grows as data is written to it. The data can be retrieved usingtoByteArray()andtoString(). Closing aByteArrayOutputStreamhas no effect. The methods in this class can be called ...
