Download Excel file functionality in Hybris e-commerce | How to make a excel download in Hybris multi-suite
Friends there was a requirnment in Hybris project to create a http link to export data in excel format
implementation
First create a controller and from your controller follow below step
ExcelExportController.java
/**
*
*/
package com.occ.controller;
import java.util.List;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.ServletRequestUtils;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import com.occ.facade.export.ExportFacade;
@Controller
public class ExportController
{
@Autowired
private ExportFacade dlExportFacade;
@RequestMapping(value = "/v1/export", method = RequestMethod.GET)
protected ModelAndView export(final HttpServletRequest request, final HttpServletResponse response) throws Exception
{
final List<Map<String, String>> deal = dlExportFacade.getExportData();
return new ModelAndView("export", "Data", deal);
}
@RequestMapping(value = "/v1/Export", method = RequestMethod.GET)
protected ModelAndView Export(final HttpServletRequest request, final HttpServletResponse response) throws Exception
{
final String output = ServletRequestUtils.getStringParameter(request, "output");
final List<Map<String, String>> deal = dlExportFacade.getExportData();
if (output == null || "".equals(output))
{
//return normal view
//
ModelAndView("ExcelExport", "Data", revenueData);
return new ModelAndView("ExcelExport", "Data", deal);
}
else if ("EXCEL".equals(output.toUpperCase()))
{
//return excel view
return new ModelAndView("ExcelExport", "Data", deal);
}
else
{
//return normal view
return new ModelAndView("ExcelExport", "Data", deal);
}
}
}
Facade Layer
DefaultExportFacade.java
/**
*
*/
package com.occ.facade.export.impl;
import java.util.List;
import java.util.Map;
import com.occ.facade.export.ExportFacade;
import com.occ.service.ExportService;
public class DefaultExportFacade implements ExportFacade
{
/**
* @return the ExportService
*/
public ExportService getExportService()
{
return ExportService;
}
/**
* @param ExportService
* the ExportService to set
*/
public void setExportService(final ExportService ExportService)
{
this.ExportService = ExportService;
}
public ExportService ExportService;
/*
* (non-Javadoc)
*
* @see com.occ.facade.export.ExportFacade#getExportData()
*/
@Override
public List<Map<String, String>> getExportData()
{
return ExportService.getExportData();
}
}
Service Layer
ExportService.java
/**
*
*/
package com.occ.service;
import java.util.List;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import com.occ.dao.ExportDao;
public class ExportService
{
@Autowired
private ExportDao dlExportDao;
public List<Map<String, String>> getExportData()
{
return dlExportDao.getExportData();
}
}
Excel view
/**
*
*/
package com.occ.view;
import java.util.List;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.springframework.web.servlet.view.document.AbstractExcelView;
public class ExportView extends AbstractExcelView
{
@Override
protected void buildExcelDocument(final Map model, final HSSFWorkbook workbook, final HttpServletRequest request,
final HttpServletResponse response) throws Exception
{
final List<Map<String, String>> revenueData1 = (List<Map<String, String>>) model.get("Data");
//create a wordsheet
final HSSFSheet sheet = workbook.createSheet(" Export");
final HSSFRow header = sheet.createRow(0);
int rowNum = 1;
for (int i = 0; i < revenueData1.size(); i++)
{
final HSSFRow row = sheet.createRow(rowNum++);
final Map<String, String> data = revenueData1.get(i);
}
}
}
