我让我的saveScreenShot线程内存溢出错误，即使是BlockingQueue的空内存溢出使用ImageIO.write在我的主要

存在时，下列变量存储图像

public static BlockingQueue imageQueue1 = new LinkedBlockingQueue();

public static BlockingQueue imageQueue2 = new LinkedBlockingQueue();

public static BlockingQueue imageQueue3 = new LinkedBlockingQueue();

public static BlockingQueue imageQueue4 = new LinkedBlockingQueue();

这里是我的ImageSaveData类

import java.awt.image.BufferedImage;

public class ImageSaveData

{

private String fileNumber;

private BufferedImage image;

public ImageSaveData(String fileNumber, BufferedImage image)

{

this.fileNumber = fileNumber;

this.image = image;

}

public String getFileNumber()

{

return fileNumber;

}

public BufferedImage getImage()

{

return image;

}

}

这里是我的线程，需要一个屏幕截图并保存它imageQueueX

// long start = System.currentTimeMillis();

synchronized (runner)

{

int imageCount = 0;

int maxCount = 0;

boolean hasMessage = false;

String[] countFormat =

{

"00000000", "0000000", "000000", "00000", "0000", "000", "00", "0"

};

// 10

while (true)

{

if (maxCount++ < 1000000010)

{

try

{

BufferedImage image = new Robot().createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));

String imageOutNumb = "";

if (imageCount < 10) imageOutNumb = countFormat[0] + imageCount++;

else if (imageCount < 100) imageOutNumb = countFormat[1] + imageCount++;

else if (imageCount < 1000) imageOutNumb = countFormat[2] + imageCount++;

else if (imageCount < 10000) imageOutNumb = countFormat[3] + imageCount++;

else if (imageCount < 10000000) imageOutNumb = countFormat[6] + imageCount++;

else if (imageCount < 100000000) imageOutNumb = countFormat[7] + imageCount++;

else imageOutNumb = "" + imageCount++;

ImageSaveData imageSaveData = new ImageSaveData(imageOutNumb, image);

while (true)

{

if (Main.imageQueue1.offer(imageSaveData, 1, TimeUnit.NANOSECONDS)) break;

if (Main.imageQueue2.offer(imageSaveData, 1, TimeUnit.NANOSECONDS)) break;

if (Main.imageQueue3.offer(imageSaveData, 1, TimeUnit.NANOSECONDS)) break;

if (Main.imageQueue4.offer(imageSaveData, 1, TimeUnit.NANOSECONDS)) break;

}

}

catch (HeadlessException | AWTException e)

{

e.printStackTrace();

}

catch (InterruptedException e)

e.printStackTrace();

catch(OutOfMemoryError e)

else

System.out.println(Main.imageQueue2.isEmpty());

System.out.println(Main.imageQueue3.isEmpty());

System.out.println(Main.imageQueue4.isEmpty());

}

catch (Exception e)

{

}

}

else

{

System.out.println("We Have Finished saving images to memory");

hasMessage = true;

}

}

}

}

我有3个消费者线程的唯一diffrence是，文件路径是不同势

// long start = System.currentTimeMillis();

synchronized (runner)

{

String PathName = "\\\\DELL\\Maxtor\\aJordan\\";

while (true)

{

try

{

ImageSaveData imageData1 = Main.imageQueue1.poll(1, TimeUnit.NANOSECONDS);

ImageSaveData imageData2 = Main.imageQueue1.poll(1, TimeUnit.NANOSECONDS);

ImageSaveData imageData3 = Main.imageQueue1.poll(1, TimeUnit.NANOSECONDS);

ImageSaveData imageData4 = Main.imageQueue1.poll(1, TimeUnit.NANOSECONDS);

if (imageData1 != null) ImageIO.write(imageData1.getImage(), "png", new File(PathName + imageData1.getFileNumber() + ".png"));

if (imageData2 != null) ImageIO.write(imageData2.getImage(), "png", new File(PathName + imageData2.getFileNumber() + ".png"));

if (imageData3 != null) ImageIO.write(imageData3.getImage(), "png", new File(PathName + imageData3.getFileNumber() + ".png"));

if (imageData4 != null) ImageIO.write(imageData4.getImage(), "png", new File(PathName + imageData4.getFileNumber() + ".png"));

}

catch (InterruptedException e)

{

// TODO Auto-generated catch block

e.printStackTrace();

}

catch (IOException e)

{

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}
