基于spring-boot的邮件发送的代码

1.pom.xml引入如下jar
<dependency>
 <groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
2.在application.properties里配置如下信息：
spring.mail.properties.mail.smtp.connecttimeout=5000
spring.mail.properties.mail.smtp.timeout=3000
spring.mail.properties.mail.smtp.writetimeout=5000
spring.mail.host=xxxxxxx
spring.mail.username=xxxx
spring.mail.password=xxx
spring.mail.port=25

spring.mail.properties.mail.smtp.auth=true
