java 使用EasyExcel导出Excel

maven仓库：
	   
			com.alibaba
			easyexcel
			1.1.2-beta5
   		 

后台代码：   
/**
	 * 导出Excel
	 */
	@RequestMapping("/exportMsg")
	@ResponseBody
	public int exportMsg(@RequestParam("codeId") Long codeId ,HttpServletResponse response) {
		int r = 0;
		try {

			List exportAuthUsers  = authenBusinessService.findByExportInviteCode(codeId);
			OutputStream out = response.getOutputStream();
			response.setContentType("multipart/form-data");
			response.setCharacterEncoding("utf-8");
			String fileName= URLEncoder.encode("客户列表","utf-8");//设置导出格式
			response.setHeader("Content-disposition", "attachment;filename="+fileName+".xlsx");
			ExcelUtil.writer(out,"人员列表",exportAuthUsers, ExportAuthUser.class);
			out.flush();
			r=1;
		} catch (IOException e) {
			e.printStackTrace();
		}
		return r;
	}

后台工具类：

 /**
     * 导出Excel
     * @param out Servlet 流
     * @param sheetName sheet名称
     * @param data 数据
     * @param clazz 对应数据Class
     */
    public static void writer(OutputStream out, String sheetName, List data,Class clazz){
        ExcelWriter writer = new ExcelWriter(out, ExcelTypeEnum.XLSX, true);
        Sheet sheet1 = new Sheet(1, 0, clazz);
        sheet1.setSheetName(sheetName);
        sheet1.setAutoWidth(Boolean.TRUE);
        writer.write(data,sheet1);
        writer.finish();
    }


前台请求（不能使用ajax请求）：
     $('#outExcel').click(function(){
            var  codeIds = $("#codeIds").val();
			window.location.href = '${ctx}/datas/exportMsg?codeId='+codeIds;
       }
