public abstract class AbstractJExcelView extends AbstractView
This class uses the JExcelAPI instead of POI. More information on JExcelAPI can be found on their website.
Properties:
The file will be searched with locations in the following order:
For working with the workbook in the subclass, see Java Excel API site
As an example, you can try this snippet:
protected void buildExcelDocument(
Map<String, Object> model, WritableWorkbook workbook,
HttpServletRequest request, HttpServletResponse response) {
if (workbook.getNumberOfSheets() == 0) {
workbook.createSheet("Spring", 0);
}
WritableSheet sheet = workbook.getSheet("Spring");
Label label = new Label(0, 0, "This is a nice label");
sheet.addCell(label);
}
The use of this view is close to the AbstractExcelView class,
just using the JExcel API instead of the Apache POI API.AbstractExcelView,

Subclasses must implement this method to create an Excel Workbook
document, given the model.

generatesDownloadContent()
Return whether this view generates download content
(typically binary content like PDF or Excel files).

protected jxl.Workbook |
getTemplateSource(String url,
HttpServletRequest request)
Create the workbook from an existing XLS document.
|
protected void |
renderMergedOutputModel(Map<String,Object> model,
HttpServletRequest request,
HttpServletResponse response)
Renders the Excel view, given the specified model.
|

protected boolean generatesDownloadContent()
AbstractViewThe default implementation returns false. Subclasses are
encouraged to return true here if they know that they are
generating download content that requires temporary caching on the
client side, typically via the response OutputStream.
