我有方法在base64中将图像作为字符串获取并缩放（如果需要）并将其转换为BufferedImage然后在ByteArrayInputStream中，并且在我将此图像加载到Google云后，但我发现了即使我没有加载到goole云中，我也会获得OutOfMemory，所以我测试了我的方法uploadJpgFromBase64，而且我确实得到了OutOfMemory。
我的uploadJpgFromBase64：
package com.myproject.model.utils.google;
import org.imgscalr.Scalr;
import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Base64;
public class Gcloud {
public static String uploadJpgFromBase64(String path, String content, int width, int height) throws Exception {
String imageDataBytes = content.substring(content.indexOf(",") + 1);
byte[] decodedString = Base64.getDecoder().decode(imageDataBytes);
BufferedImage image = bufferedImage(decodedString);
int imgWidth = image.getWidth();
int imgHeight = image.getHeight();
if (imgWidth > width || imgHeight > height) {
BufferedImage resize = Scalr.resize(image, width, height);
BufferedImage newBufferedImage = new BufferedImage(resize.getWidth(), resize.getHeight(), BufferedImage.TYPE_INT_RGB);
newBufferedImage.createGraphics().drawImage(resize, 0, 0, Color.WHITE, null);
try (ByteArrayOutputStream os = new ByteArrayOutputStream()) {
ImageIO.write(newBufferedImage, "jpg", os);
resize.flush();
newBufferedImage.flush();
InputStream inputStream = new ByteArrayInputStream(os.toByteArray());
inputStream.close();
return "test";
}
} else {
BufferedImage newBufferedImage = new BufferedImage(imgWidth, imgHeight, BufferedImage.TYPE_INT_RGB);
newBufferedImage.createGraphics().drawImage(image, 0, 0, Color.WHITE, null);
try (ByteArrayOutputStream os = new ByteArrayOutputStream()) {
ImageIO.write(newBufferedImage, "jpg", os);
newBufferedImage.flush();
InputStream inputStream = new ByteArrayInputStream(os.toByteArray());
inputStream.close();
return "test";
}
}
}
private static BufferedImage bufferedImage(byte[] decodedString) throws IOException {
try (InputStream is = new ByteArrayInputStream(decodedString)) {
return ImageIO.read(is);
}
}
}
和堆栈跟踪：

我正在使用： Glassfish 5.20 春天4.3.9.RELEASE java8
在我的本地机器中，服务器重启后，我只是通过rest api开始使用这个方法将图像加载为base64字符串，并在15-20调用之后（其中我传递了1-2张图像）每个3-5 MB）我得到OutOfMemory。
所以我假设uploadJpgFromBase64中的一个流还没有释放内存... mb，但为什么呢？
P.S。
