Spring框架_导出到Excel表格

很多时候需要把表格数据导出Excel表格，以前使用别人的框架，现在还是用别人的框架实现，哈哈。
1.ExcelManager:

public List<PageData> listAll(PageData pd)throws Exception;

2.ExcelService：

public List<PageData> listAll(PageData pd)throws Exception{
		return (List<PageData>)dao.findForList("OtherMapper.listAll", pd);
	}

3.ExcelMapper:（Field是字段，tableName是字段值。在前面<sql id ="Field">..字段..</sql>）

	<select id="listAll" parameterType="pd" resultType="pd">
		select
		<include refid="Field"></include>
		from 
		<include refid="tableName"></include>
	</select>

4.ExcelController:

@RequestMapping(value="/excel")
	public ModelAndView exportExcel() throws Exception{
		ModelAndView mv = new ModelAndView();
		PageData pd = new PageData();
		pd = this.getPageData();
		Map<String,Object> dataMap = new HashMap<String,Object>();
		List<String> titles = new ArrayList<String>();
		titles.add("名称");	//1
		titles.add("费用");	//2
		titles.add("成本");	//3
		titles.add("备注");	//4
		dataMap.put("titles", titles);
		List<PageData> varOList = otherService.listAll(pd);
		List<PageData> varList = new ArrayList<PageData>();
		for(int i=0;i<varOList.size();i++){
			PageData vpd = new PageData();
			vpd.put("var1", varOList.get(i).getString("OTHER_MANE"));	    //1
			vpd.put("var2", varOList.get(i).get("COST_MONEY").toString());	//2
			vpd.put("var3", varOList.get(i).get("COST_T").toString());	//3
			vpd.put("var4", varOList.get(i).getString("BZ"));	    //4
			varList.add(vpd);
		}
		dataMap.put("varList", varList);
		ObjectExcelView erv = new ObjectExcelView();
		mv = new ModelAndView(erv,dataMap);
		return mv;
	}

5.ExcelJsp:

//导出excel
		function toExcel(){
			window.location.href='<%=basePath%>excelJsp.do';
		}

为什么这么详细？
