springmvc實現導出數據信息爲excle表格

1.項目增加導出日誌信息

2.項目中導入poi-*.jar等操作excel文件的jar文件

poi-3.7-20120326.jar

poi-excelant-3.7-20101029.jar

poi-ooxml-3.7.jar

poi-ooxml-schemas-3.7.jar

Excel導出就是根據前臺條件將參數傳到controller，根據參數去數據庫中進行查詢，查詢出list集合，將list集合生成excle數據下載。

代碼片段：

Contorller.Java

    /** 
         * 導出信息 
         * @param model 
         */  
        @RequestMapping("exportCustomer.do")  
        @SystemControllerLog(description = "數據庫表單導出Excle")  
        public void exportCustomer(ModelMap model) {  
            //TODO 如需添加條件  
            //model.addAttribute("username", nameStr);  
            //獲取需要導出的數據List  
            List<CMcustomer> cusList=customerService.exportCustomer(model);  
                //使用方法生成excle模板樣式  
            HSSFWorkbook workbook = customerService.createExcel(cusList, request);  
            SimpleDateFormat format = new SimpleDateFormat("yyyyMMddHHmmss"); // 定義文件名格式  
      
            try {  
            //定義excle名稱 ISO-8859-1防止名稱亂碼  
                String msg = new String(  
                        ("客戶信息_" + format.format(new Date()) + ".xls").getBytes(),  
                        "ISO-8859-1");  
                // 以導出時間作爲文件名  
                response.setContentType("application/vnd.ms-excel");  
                response.addHeader("Content-Disposition", "attachment;filename="  
                        + msg);  
                workbook.write(response.getOutputStream());  
            } catch (IOException e) {  
                logger.error(e);  
            }  
        }  

2.Service中createExcel方法

    public HSSFWorkbook createExcel(List<CMcustomer> cusList,  
            HttpServletRequest request) {  
      
            // 創建一個webbook，對應一個excel文件  
            HSSFWorkbook workbook = new HSSFWorkbook();  
            // 在webbook中添加一個sheet,對應excel文件中的sheet  
            HSSFSheet sheet = workbook.createSheet("客戶信息表");  
            // 設置列寬  
            sheet.setColumnWidth(0, 25 * 100);  
            sheet.setColumnWidth(1, 35 * 100);  
            sheet.setColumnWidth(2, 35 * 100);  
            sheet.setColumnWidth(3, 40 * 100);  
            sheet.setColumnWidth(4, 45 * 100);  
            sheet.setColumnWidth(5, 45 * 100);  
            sheet.setColumnWidth(6, 50 * 100);  
            sheet.setColumnWidth(7, 80 * 100);  
            sheet.setColumnWidth(8, 35 * 100);  
            sheet.setColumnWidth(9, 40 * 100);  
            // 在sheet中添加表頭第0行  
            HSSFRow row = sheet.createRow(0);  
            // 創建單元格，並設置表頭，設置表頭居中  
            HSSFCellStyle style = workbook.createCellStyle();  
            // 創建一個居中格式  
            style.setAlignment(HSSFCellStyle.ALIGN_CENTER);  
            // 帶邊框  
            style.setBorderBottom(HSSFCellStyle.BORDER_THIN);  
            // 生成一個字體  
            HSSFFont font = workbook.createFont();  
            // 字體增粗  
            font.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);  
            // 字體大小  
            font.setFontHeightInPoints((short) 12);  
            // 把字體應用到當前的樣式  
            style.setFont(font);  
      
            // 單獨設置整列居中或居左  
            HSSFCellStyle style1 = workbook.createCellStyle();  
            style1.setAlignment(HSSFCellStyle.ALIGN_CENTER);  
            HSSFCellStyle style2 = workbook.createCellStyle();  
            style2.setAlignment(HSSFCellStyle.ALIGN_LEFT);

            hssfFont1.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);  
            style4.setFont(hssfFont1);  
      
            HSSFCell cell = row.createCell(0);  
            cell.setCellValue("序號");  
            cell.setCellStyle(style);

3.頁面jsp調用

    //導出信息  
            function exporBtn(){  
            $.ajax({  
                type:"POST",  
                url:"<%=path%>/customer/exportCustomer.do",  
                success:function(data){  
                    window.open('<%=path%>/customer/exportCustomer.do');  
                }  
                  
            });  
        }
