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

#####################actuator配置######################字符集编码默认UTF-8spring.mail.default-encoding=UTF-8#SMTP服务器hostqq邮箱的为smtp.qq.com端口465587spring.mail.host=smtp.qq.com#SMTP服务器端口不同的服务商不一样spring.mail.port=465#SMTP服务器使用的协议spring.mail.protocol=smtp#SMTP服务器需要身份验证所以要配置用户密码#发送端的用户邮箱名spring.mail.username=12345678@qq.com#发送端的密码注意保密#qq邮箱的第三方授权码并非个人密码spring.mail.password=xxxxxxxxxxx#指定mail会话的jndi名称优先级较高一般我们不使用该方式spring.mail.jndi-name=#这个比较重要针对不同的SMTP服务器都有自己的一些特色配置该属性提供了这些配置的keyvalue封装方案例如GmailSMTP服务器超时配置spring.mail.properties.mail.smtp.timeout=5000spring.mail.properties.<key>=#指定是否在启动时测试邮件服务器连接，默认为falsespring.mail.test-connection=false#开启ssl否则503错误spring.mail.properties.mail.smtp.ssl.enable=true
