Could not autowire. No beans of 'JavaMailSender' type found.

1. 导入依赖

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-mail</artifactId>
   <version>2.1.5.RELEASE</version>
</dependency>

2. 配置邮箱相关参数

mail.address = xxx@chinamobile.com
mail.receiver = xxx@126.com
spring.mail.host=smtp.chinamobile.com
spring.mail.username=xxx@chinamobile.com
spring.mail.password=xxx
spring.mail.default-encoding=UTF-8
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=false
spring.mail.properties.mail.smtp.starttls.required=false

3. 使用

原因：爆红提示找不到Could not autowire. No beans of 'JavaMailSender' type found.，原因是邮箱配置参数找不到

解决：将邮箱配置参数迁移至 resource中 的配置文件中。
