java 将base64转换成BufferedImage，将代码写出来

我可以帮您提供 Java 代码将 base64 转换为 BufferedImage：

import java.awt.image.BufferedImage;
import java.util.Base64;
import javax.imageio.ImageIO;

public class Base64ToBufferedImage {
  
  public static BufferedImage convert(String base64String) {
    BufferedImage image = null;
    try {
      byte[] imageBytes = Base64.getDecoder().decode(base64String);
      image = ImageIO.read(new ByteArrayInputStream(imageBytes));
    } catch (IOException e) {
      System.out.println("Error occurred while converting base64 to BufferedImage: " + e.getMessage());
    }
    return image;
  }
}

使用方法：

String base64String = "iVBORw0KGgoAAAANSUhEUgAAABIAAAASCAIAAABvYTE8AAAAAXNSR0IArs4c6QAAAARzQklUCAgI" + // 例子 Base64 字符串
                      "YWPJALi/AAAAGXRFWHRTb2Z0d2FyZQBBZG9iZSBJbWFnZVJlYWR5ccllPAAAAAxQTFRF////AAAA" +
                      "tpMq3gAAABV0Uk5T////////////////////////////AP//////////////////////////////////////////////////////////////ADiGhanaAAAAlwSFlzAAALEwAACxMBAJqcGAAAABZ0RVh0U29mdHdhcmUATWFjcm9tZWRpYSBGaXJld29ya3Mg"

BufferedImage image = Base64ToBufferedImage.convert(base64String);
