如何使用POI加载大型xls文件时解决java堆空间错误

我正在尝试加载和解析一个11mb的xls文件，我正在使用WorkbookFactory.create（myFile）来加载它。但是我无法加载这个文件并解析它。任何人都可以帮助我解决这个问题我在我的程序中使用的代码，

public class LargeExcelManager { private Workbook wb ; public Workbook getWb() { return wb; } public void setWb(Workbook wb) { this.wb = wb; } public LargeExcelManager(String fileName)throws Exception { openWorkbook(fileName); } private void openWorkbook(String fileName)throws Exception { try { System.out.println("Can be added now"); File myFile = new File(fileName); this.setWb(WorkbookFactory.create(myFile)); // Here i am trying to set the large file } catch (Exception e) { e.printStackTrace(); } } } 

在这里，我试图从中获取一些信息，

 @Override public List start() { ActivityLauncher.logConsoleMsg("Activity number " + activityId + " started"); List result = new ArrayList(); Workbook wb = excelManager.getWb(); for (int i=0; i<wb.getNumberOfSheets(); i++) { if(wb.getSheetName(i).contains("Loan information")) { //sheetNames.add( wb.getSheetName(i) ); result.addAll(processSheet(wb.getSheetAt(i))); } } ActivityLauncher.logConsoleMsg("Activity number " + activityId + " completed"); return result; } 

但是每次我试图加载它都会让我失望。 有人能以某种方式帮助我吗？

我使用POI 3.16收到此错误
