我非常确定代码是正确的，并且 100% 肯定我输入的用户名和密码详细信息是正确的。那么这是gmail的问题还是什么？
这是我的代码：

private String host = "smtp.gmail.com";
private String emailLogin = "xxx@gmail.com";
private String pass = "xxx";

此代码从 url 写入获取文件并将其写入我的本地主页（例如 D 盘）
如何在不保存本地的情况下将其附加到邮件发件人？是否可以？
我正在尝试在调用此方法的 Java 应用程序中发送电子邮件：

// set socket factory
//props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
// set the authentication to true
props.put("mail.smtp.auth", "true");
// set the port of SMTP server
props.put("mail.smtp.port", "587");
// This will handle the complete authentication

这是在 application.properties 中配置邮件发送的属性
mail.enable=true

spring.mail.username=abc@gmail.com
spring.mail.password=**************
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.socketFactory.port=465
mail.smtp.port=2525

spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.smtp.socketFactory.fallback=false

我该如何重新配置这个？我尝试遵循特定的密码模式。将不胜感激任何建议。
