java導出excel 瀏覽器直接下載或者或以文件形式導出

這篇文章主要介紹了java導出excel 瀏覽器直接下載或者或以文件形式導出方式，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教

看代碼吧~

/**
 * excel表格直接下載
 */
public static void exportExcelByDownload(HSSFWorkbook wb,HttpServletResponse httpServletResponse,String fileName) throws Exception {
    //響應類型為application/octet- stream情況下使用了這個頭信息的話，那就意味著不想直接顯示內容
    httpServletResponse.setContentType(MediaType.APPLICATION_OCTET_STREAM_VALUE);
    //attachment為以附件方式下載
    httpServletResponse.setHeader("Content-Disposition","attachment;filename=" + URLEncoder.encode(
            fileName + ".xls",
            "utf-8"));
    /**
     * 代碼里面使用Content-Disposition來確保瀏覽器彈出下載對話框的時候。
     * response.addHeader("Content-Disposition","attachment");一定要確保沒有做過關于禁止瀏覽器緩存的操作
     */
    httpServletResponse.setHeader("Cache-Control", "No-cache");
    httpServletResponse.flushBuffer();
    wb.write(httpServletResponse.getOutputStream());
    wb.close();
}
/**
 * excel以文件的形式導出
 * @throws Exception
 */
public static void exportExcelByFile(HSSFWorkbook wb,String fileName,String path) throws Exception{
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    wb.write(stream);
    FileOutputStream outputStream = new FileOutputStream(path + fileName);
    outputStream.write(stream.toByteArray());
    stream.close();
    outputStream.close();
}

java查詢數(shù)據(jù)導出excel并返回給瀏覽器下載

效果圖：

1.點擊導出表按鈕

2.接著就會出現(xiàn)下圖

3.點擊上圖中的確定按鈕再接著就會出現(xiàn)下圖

4.點擊上圖中的保存按鈕接著就會出現(xiàn)下圖，瀏覽器下載完成后的提示

5.打開下載好的文件如下圖

好了，廢話不多少，上代碼

jsp前端代碼
