1.下载：

https://download.csdn.net/download/q908544703/85277974

2.web端代码:

       getOnlineFile:function(projectAttachId){
            //http://localhost:8080/km/attachFileEs/downloadPdf?projectAttachId='11111'
            var FileUrl =baseUrl + 'km/attachFileEs/downloadPdf?projectAttachId='+ projectAttachId+"&document.title=33.pdf";
            var urls="../../pdf/web/viewer.html?file="+encodeURIComponent(FileUrl);
            window.open( urls);
        }

//注意参数 filename是额外处理的 文件名获取不到 需额外传参数 在pdfjs里面处理document.title
实际打开地址

http://127.0.0.1:8091/src/page/ceo/km/html/pdf/web/viewer.html?file=%2Fkm%2FattachFileEs%2FdownloadPdf%3FprojectAttachId%3D1797d2d56281464d970de28f2be0a93f%26document.title%3D33.pdf

3.java 代码实现

  /**
     * 预览pdf文件
     * @author Mike
     * @param request
     * @param response
     * @param projectAttachId
     */
    @RequestMapping(value = "/downloadPdf", method = RequestMethod.GET)
    public void pdfStreamHandeler(HttpServletRequest request, HttpServletResponse response,String projectAttachId) {
        String filePath = "F:\\ZFU资料\\年中十讲笔记完整版.pdf";

//        System.out.println(fileName);
        File file = new File(filePath);
        byte[] data = null;
        FileInputStream input=null;
        try {
            input = new FileInputStream(file);
            data = new byte[input.available()];
            input.read(data);
            response.getOutputStream().write(data);
            input.close();
        } catch (Exception e) {
            System.out.print("pdf文件处理异常：" + e.getMessage());
        } finally {
            try {
                input.close();
            } catch (IOException e) {
                logger.error("InputStream关闭异常", e);
            }

        }

    }
