Spring Boot整合邮箱进行发送

1. 添加依赖

在pom.xml文件中添加spring-boot-starter-mail依赖，如下所示：

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

2. 配置邮件发送参数

在application.properties或application.yml文件中配置邮件发送参数，如下所示：

# 邮件服务器地址和端口号
spring.mail.host=smtp.qq.com
spring.mail.port=587
# 发件人邮箱账号和密码
spring.mail.username=your_email@qq.com
spring.mail.password=your_email_password
# 收件人邮箱账号（可以同时设置多个）
spring.mail.receivers=receiver1@example.com,receiver2@example.com
# 邮件编码格式
spring.mail.properties.mail.default-encoding=UTF-8

3.编写邮件发送服务类

创建一个邮件发送服务类，使用JavaMailSender接口实现邮件发送功能，如下所示：
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;@Service
public class EmailService {@Autowiredprivate JavaMailSender javaMailSender;public void sendEmail(String subject, String text) {SimpleMailMessage message = new SimpleMailMessage();  // 实例化邮件对象message.setFrom("your_email@qq.com");  // 发件人邮箱账号message.setTo("receiver1@example.com,receiver2@example.com");  // 收件人邮箱账号，多个账号用逗号分隔message.setSubject(subject);  // 邮件主题message.setText(text);  // 邮件内容javaMailSender.send(message);  // 发送邮件}
}

4. 调用邮件发送服务类的方法发送邮件

@Autowired
private EmailService emailService;
...
emailService.sendEmail("Hello World", "This is a test email sent by Spring Boot!");
