如何在当前项目路径下生成文件

• 生成文件在指定目录的方法演示
• System.getProperty("user.dir") 是获取当前项目的路径

 public FileOutputStream createFileOutPutStream(String pdfFileName) throws IOException {
        File file=new File(System.getProperty("user.dir") + "/file/plan/"+pdfFileName+".pdf);
        //如果文件夹不存在则创建
        if  (!file.exists()  && !file.isDirectory())
        {
            boolean mkdir = file.mkdirs();
            System.out.println(mkdir);
        }
        FileOutputStream stream =new FileOutputStream(System.getProperty("user.dir") + "/file/plan/"+pdfFileName+".pdf");
        return stream;
    }

• 在当前项目下创建了目录和文件~
  

获取当前项目目录下文件

    public void getInventoryPdf(String pdfFileName, HttpServletResponse response) throws IOException {
        response.reset();
        response.setHeader("Content-Type", "application/pdf");
        response.setContentType("application/pdf");
        response.setHeader("Content-Disposition", "attachment; filename=" + URLEncoder.encode("pdf文件", "UTF-8"));
        File file = new File(System.getProperty("user.dir") + "/file/plan/"+pdfFileName+".pdf");
        FileInputStream fis = new FileInputStream(file);
        byte[] bytes = new byte[fis.available()];
        fis.read(bytes);
        fis.close();
        OutputStream out = response.getOutputStream();
        out.write(bytes);
        out.flush();
        out.close();
    }
