使用java打印服务打印tiff文件时出现java.lang.OutOfMemoryError

Question

我正在使用Java打印服务打印tiff文件，它会导致"Java.lang.OutOfMemoryError:Java堆空间"。

private void sendToPrinter(String fileToPrint) throws PrintException, IOException
{
/* Use the pre-defined flavor for a GIF from an InputStream */
DocFlavor flavor = DocFlavor.INPUT_STREAM.PNG;
/* Create a set which specifies how the job is to be printed */
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
aset.add(MediaSizeName.NA_LETTER);
aset.add(new Copies(1));
/* Create a Print Service using the default printer */
PrintService ps=PrintServiceLookup.lookupDefaultPrintService();
DocPrintJob job=ps.createPrintJob();
//          System.gc();
try (FileInputStream fis=new FileInputStream(fileToPrint))
{
Doc doc=new SimpleDoc(fis, flavor, null); 
job.print(doc, aset);
}
}

tif文件非常小，略高于500K，包含7页。谷歌搜索了很多，但找不到太多帮助。看到一篇帖子建议在打印前明确调用垃圾回收。尝试过，但没有成功。JVM堆大小已设置为最大512mb。

java-vm-args="-Xms128m -Xmx512m -XX:PermSize=32m -XX:MaxPermSize=128m"

该程序的目标是在完成装运处理后，自动将证书副本打印到用户的默认打印机(无需用户交互(。

既然文件没有那么大，为什么会导致内存问题，以及如何解决？

提前谢谢。

请尝试以下步骤。

1. 使用以下命令从命令提示符启动应用程序

   java-jar-Xmx1024M-XX:+PrintGCDetails-XX:+PrintGCDateStamps"\your.jar">>C:\Temp\Log.txt

2. 打开一个新的命令提示符，导航到JDK Bin目录并键入

   jcmd

3. 现在记下流程的流程ID并键入

   jmap-堆

   4. 现在您将知道有多少内存被分配给年轻、旧和堆，以及使用了多少百分比

这将帮助您了解应用程序的情况。请试着让我们知道它是否有帮助。
