我在java/jsp中有一個web應用程序。在我們的應用程序中有多個選項卡，並且在其中一個選項卡中，我必須顯示Excel表格中的數據。我試圖通過使用另存爲網頁選項將Excel錶轉換爲data.html文件。但是，當我嘗試包括在標籤中的HTML文件，即時得到下面的錯誤消息在jsp頁面顯示Excel數據
This content cannot be displayed in a frame
我也試圖通過Tomcat服務器在Eclipse中運行的HTML文件，但得到了上述消息。當我嘗試通過網絡瀏覽器打開它時，數據會正確顯示。
我需要幫助獲取顯示在jsp頁面中的excel數據。任何幫助，這是非常感謝。謝謝
當您的服務器端（Tomcat，Glassfish，Wildfly或其他servlet容器）上的Excel表單時，您可以使用POI部署一些行代碼來讀取excel文件。
https://poi.apache.org/spreadsheet/quick-guide.html#FileInputStream
然後，你可以創建一個小的JSP動態...顯示結果的HTML表格。
請結帳http://w3lessons.info/2015/07/13/export-html-table-to-excel-csv-json-pdf-png-using-jquery/。可以幫忙，如果不是請也請檢查apache-poi。
Columns marked with read box willl be displayed i have attached image here
你可以通過從servlet的數據使用下面的代碼它的工作原理如下
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);

只是忽略
標籤刪除並在您的jsp中添加代碼 –
什麼是您的Web應用程序的URL，以及從Excel轉換而來的HTML文件的URL是什麼？ –
web應用程序的url爲「http：// localhost：8080/pm/login.jsp。我無法使用tomcat服務器運行html文件，當我在eclipse中的瀏覽器中打開文件時，出現的URL是file：/// D：/PMProject/workspace/PM/WebContent/Data.html – vr3w3c9
