我的要求是使用通用PDF，我必须为电子邮件附加一个静态PDF，我可以附加通用PDF而没有任何问题，但是从目录中获取它时却给我一个静态PDF的问题，尝试了几种方法，请您提供帮助....

下面是错误以及与之相关的代码。...

Answer 1

在下面使用：

File pdfFile = new File("/mnt/DGB/Correspondence/Systems/PROD_DOCS/How_to_access_member_information.pdf");

添加以下内容：

在用户主目录下创建一个目录，例如：/home/user_name/java-pdf。然后，尝试以下代码一次，以检查您的代码是否能够访问该文件：

File homedir = new File(System.getProperty("user.home"));
File pdfFile = new File(homedir, "java-pdf/How_to_access_member_information.pdf");

上面的代码对我来说很好。

在目录中找不到文件（静态PDF附件）
