</dependency>application.properties的配置:注意,我使用的是163邮箱发送邮件,如果使用qq邮箱发送,配置会稍有不同
# JavaMailSender 邮件发送的配置
spring.mail.host=smtp.163.com
#邮件发送者
[email protected]
#邮件的接收者
[email protected]
#设置的是客户端授权密码,不是邮箱的登录密码
spring.mail.password=xxx
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
qq邮箱发送邮件发的配置:
######qq邮箱########
spring.mail.host=smtp.qq.com
spring.mail.username=******@qq.com
#QQ邮箱授权码
spring.mail.password=xuojxtkdojvzbhjj
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
注意密码的配置,设置的是客户端授权密码,不是邮箱的登录密码,以163邮箱为例,需要保证如下的设置
登录163邮箱,修改如下的操作
需要开启如下的授权码,在properties中配置的密码就是这个开启的授权码,不能是密码
