springboot发送邮件 outlook

以下是使用SpringBoot发送邮件的示例代码，其中包括了如何发送带附件的邮件和如何开启TLS验证：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.mail.MailProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.File;

@SpringBootApplication
@EnableConfigurationProperties(MailProperties.class)
public class MailApplication {

    @Autowired
    private JavaMailSender mailSender;

    @Autowired
    private MailProperties mailProperties;

    public static void main(String[] args) {
        SpringApplication.run(MailApplication.class, args);
    }

    public void sendMailWithAttachment() throws MessagingException {
        MimeMessage message = mailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(message, true);
        helper.setFrom(mailProperties.getUsername());
        helper.setTo("recipient@example.com");
        helper.setSubject("Test email with attachment");

        // 添加附件
        FileSystemResource file = new FileSystemResource(new File("attachment.txt"));
        helper.addAttachment("attachment.txt", file);

        // 发送邮件
        mailSender.send(message);
    }
}

在application.properties文件中添加以下配置：

spring.mail.username=xxxxxxx@outlook.com
spring.mail.password=xxxxxxxxx
spring.mail.port=587
spring.mail.host=smtp-mail.outlook.com
spring.mail.properties.mail.smtp.starttls.required=true

注意：在使用Outlook发送邮件时，需要开启TLS验证，否则会显示匿名用户无法通过验证。
