如何使用Java代码在JSP页面中查看Excel文件？
我想直接在JSP页面中显示 Excel页面，而不仅仅是数据。 Excel格式的完全Excel页面。
public static void main(String args[]) {
}

你可以使用下面的代码将数据从servlet传递给jsp它工作正常Modules.java（Servlet页面）和Modules.jsp页面代码如下所示
FileInputStream file1 = new FileInputStream(new File("your_file_path"));
System.out.println(file1);
file.close();
//Create Workbook instance holding reference to .xlsx file
XSSFWorkbook workbook111 = new XSSFWorkbook(file1);
//Get first/desired sheet from the workbook
XSSFSheet sheet111 = workbook111.getSheetAt(0);
Object[][] bookData_read = new String[sheet111.getLastRowNum()+1][3];
int row_count11 = 0;
Iterator<Row> rowIterator111 = sheet111.iterator();
while (rowIterator111.hasNext())
{
Row row111 = rowIterator111.next();
if (row_count11 == 0) {
row_count11++;
continue;
}
if (row_count11 > sheet111.getLastRowNum())
break;
Cell cell11 = row111.getCell(4);
String cellvalue1 = "";
if (cell11 != null && ! "".equals(cell11.getStringCellValue()) ||cell11 != null && ! "".equals(cell11.getNumericCellValue())) {
switch (cell11.getCellType()) {
case Cell.CELL_TYPE_STRING:
//System.out.print(cell.getStringCellValue());
cellvalue1 = cell11.getStringCellValue();
break;
case Cell.CELL_TYPE_BOOLEAN:
//System.out.print(cell.getBooleanCellValue());
cellvalue1 = "" + cell11.getBooleanCellValue();
break;
case Cell.CELL_TYPE_NUMERIC:
//System.out.print(cell.getNumericCellValue());
cellvalue1 = "" + cell11.getNumericCellValue();
break;
}}
String module1 = cellvalue1;
//System.out.println("module"+module1);
//System.out.println(cellvalue);
bookData_read[row_count11][0] = cellvalue1;
if(row111.getCell(5)!=null)
{
Cell cell2 = row111.getCell(5);
cellvalue1 = "";
if (cell2 != null && ! "".equals(cell2.getStringCellValue())) {
switch (cell2.getCellType()) {
case Cell.CELL_TYPE_STRING:
//System.out.print(cell.getStringCellValue());
cellvalue1 = cell2.getStringCellValue();
break;
case Cell.CELL_TYPE_BOOLEAN:
//System.out.print(cell.getBooleanCellValue());
cellvalue1 = "" + cell2.getBooleanCellValue();
break;
case Cell.CELL_TYPE_NUMERIC:
//System.out.print(cell.getNumericCellValue());
cellvalue1 = "" + cell2.getNumericCellValue();
break;
} }}
String submodule = cellvalue1;
//System.out.println("submodule"+submodule);
// System.out.println(cellvalue);
bookData_read[row_count11][1] = cellvalue1;
if(row111.getCell(5)!=null && ! "".equals(row111.getCell(5).getStringCellValue()) )
{
// if(row.getCell(7)!=null && ! "".equals(row.getCell(7).getStringCellValue()))
// {
//
Cell cell3 = row111.getCell(8);
cellvalue1 = "";
if (cell3 != null && ! "".equals(cell3.getStringCellValue())) {
switch (cell3.getCellType()) {
case Cell.CELL_TYPE_STRING:
cellvalue1 = cell3.getStringCellValue();
break;
case Cell.CELL_TYPE_BOOLEAN:
cellvalue1 = "" + cell3.getBooleanCellValue();
break;
case Cell.CELL_TYPE_NUMERIC:
cellvalue1 = "" + cell3.getNumericCellValue();
break;}}
String temp = cellvalue1;
bookData_read[row_count11][2] = cellvalue1;
}
else{
continue;
}
row_count11++;
}
workbook111.close();
request.setAttribute("modulesList", bookData_read);
RequestDispatcher rd = request.getRequestDispatcher("/All_Modules.jsp");
rd.forward(request, response);
Modules.jsp page

对于客户端，有Excel，对于网络，有Google表格。 如果您获取整个Excel文件的原因是公式，请检查以下链接。
https://poi.apache.org/spreadsheet/formula.html
POI已经支持350多种内置功能。 或者如果您希望无论发生什么样的要求，IE浏览器中都有一个支持ActiveX对象的选项，这些选项不能在其他操作系统中运行。
