我刚试过一个示例代码表格网,它显示如下警告
SimpleConvertImage.java:7:警告:com.sun.org.apache.xerces.internal.impl.dv.util.Base64是内部专有API,可能会在将来的版本导入com.sun.org.apache.xerces中删除. internal.impl.dv.util.Base64; ^
SimpleConvertImage.java:16:警告:com.sun.org.apache.xerces.internal.impl.dv.util.Base64是内部专有API,可能会在将来的版本中删除String base64String = Base64.encode(baos.toByteArray()); ^
SimpleConvertImage.java:19:警告:com.sun.org.apache.xerces.internal.impl.dv.util .Base64是内部专有API,可能会在将来的发布字节中删除[] bytearray = Base64.decode(base64String) ; ^
代码如下
import java.awt.image.BufferedImage;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import com.sun.org.apache.xerces.internal.impl.dv.util.Base64;
public class SimpleConvertImage {
public static void main(String[] args) throws IOException{
String dirName="/root/Desktop";
ByteArrayOutputStream baos=new ByteArrayOutputStream(1000);
BufferedImage img=ImageIO.read(new File(dirName,"Screenshot.png"));
ImageIO.write(img, "png", baos);
baos.flush();
String base64String=Base64.encode(baos.toByteArray());
baos.close();
byte[] bytearray =Base64.decode(base64String);
BufferedImage imag=ImageIO.read(new ByteArrayInputStream(bytearray));
ImageIO.write(imag, "png", new File(dirName,"snap3.png"));
}
}
