Springboot JavaMailSender发送邮件（QQ和163）

引入maven依赖包

<dependency>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-mail</artifactId></dependency>

application.properties(163邮箱)

#####163邮箱########spring.mail.host=smtp.163.comspring.mail.username=*****@163.com#163邮箱密码spring.mail.password=!@#$%^&*spring.mail.properties.mail.smtp.auth=truespring.mail.properties.mail.smtp.starttls.enable=truespring.mail.properties.mail.smtp.starttls.required=true

qq邮箱

qq邮箱对应的是验证码，不是密码

######qq邮箱########spring.mail.host=smtp.qq.comspring.mail.username=******@qq.com#QQ邮箱授权码spring.mail.password=xuojxtkdojvzbhjjspring.mail.properties.mail.smtp.auth=truespring.mail.properties.mail.smtp.starttls.enable=truespring.mail.properties.mail.smtp.starttls.required=true

常见问题

1.发送邮件535错误

问题是因为配置文件中配置的邮箱密码是登录密码而不是安全密码导致的，直接将密码修改成安全密码就可以了（163邮箱在开启smtp服务时会要求输入安全密码的）

2.554错误

引发次问题是因为此邮件触发了163邮箱服务器反垃圾规则具体原因在错误上已经提示了，到这里查看即可
