注意备忘的坑

1.当前代码对应的依赖版本是1.5.4

<dependency> <groupId>com.sun.mail</groupId> <artifactId>javax.mail</artifactId> <version>1.5.4</version> </dependency>

对应的区别就是:

mailProps.put("mail.smtp.socketFactory", "javax.net.ssl.SSLSocketFactory");

key中不能带有.class

对于其他的更高或者其他版本的内容没有进行详细的研究.

我们使用的是163企业邮箱,查询邮箱的ssl端口使用的是:

https://qiye.163.com/help/client-profile.html

进行查询.

 

关于配置文件:

mail: smtp: smtp.qiye.163.com smtpport: 25 smtpsslport: 994 username: eport@qiye.163.com password: jtBQDmU34n4YqtKjy #注意此处的设置是从邮箱设置中获取的授权码,这里并不是邮箱用户的密码

总之就是很多坑.
