springboot发送邮件

可以使用JavaMailSender类来发送邮件，Spring Boot已经为我们提供了自动配置。首先需要在pom.xml文件中添加依赖：

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

然后在application.properties文件中配置邮件服务器信息：

spring.mail.host=smtp.example.com
spring.mail.port=587
spring.mail.username=yourusername
spring.mail.password=yourpassword
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true

最后在代码中使用JavaMailSender发送邮件即可：

@Autowired
private JavaMailSender javaMailSender;

public void sendEmail() {
    SimpleMailMessage message = new SimpleMailMessage();
    message.setTo("recipient@example.com");
    message.setSubject("Test Email");
    message.setText("This is a test email.");
    javaMailSender.send(message);
}
