我在Spring框架應用程序中出現內存不足錯誤。我禁用了一些過濾器（如安全過濾器）。但是現在錯誤發生在JSP頁面上。我的JSP頁面很重，並使用Tile Framework。java.lang.OutOfMemoryError：JSP頁上的Java堆空間
不幸的是，我擁有的主機只提供32 MB的堆空間，我無法增加它。
我在我的佈局頁添加了幾行字：
final long MEGABYTE = 1024L * 1024L;
// Get current size of heap in bytes
long heapSize = Runtime.getRuntime().totalMemory();
out.println("Total Memory (MB): "+(heapSize/MEGABYTE));
// Get maximum size of heap in bytes. The heap cannot grow beyond this size.
// Any attempt will result in an OutOfMemoryException.
long heapMaxSize = Runtime.getRuntime().maxMemory();
out.println("<br/>Heap Max Size (MB): "+(heapMaxSize/MEGABYTE));
// Get amount of free memory within the heap in bytes. This size will increase
// after garbage collection and decrease as new objects are created.
long heapFreeSize = Runtime.getRuntime().freeMemory();
out.println("<br/>Heap Free Size (MB): "+(heapFreeSize/MEGABYTE));
上面打印以下的輸出（HTML頁）輸出
Total Memory (MB): 29
Heap Max Size (MB): 29
Heap Free Size (MB): 3
這裏是堆棧跟蹤：

你的問題是什麼？我想我們需要一些代碼才能夠幫助你。 – Shaded
我的問題是，我想通過使用一些減少內存空間或類似內容的JSP最佳實踐，甚至在32 MB空間中擺脫Out of Heapspace錯誤。 –
