Spring Boot 发送邮件

待我称王封你为后i 2023-01-18 09:22 54阅读 0赞

第一步：引入Spring Boot整合邮件的依赖

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
        <version>2.2.6.RELEASE</version>
    </dependency>

第二步：例如以网易云邮箱为例，在设置中开通pop3服务并获取一个授权码

第三步：yml配置文件中添加下述配置

spring:
      mail:
        host: smtp.163.com
        port: 25
        username: 邮箱账号
        password: 生成的授权码
        default-encoding: utf-8
        properties:
          mail:
            smtp:
              auth: true
              starttls:
                enable: true
                required: true

第四步：构建实体类

import lombok.Data;
    
    @Data
    public class MailDTO {
        //接受邮件的邮箱账户
        private String mailAccount;
        //邮箱标题
        private String title;
        //要发送的内容
        private String content;
    }

第五步：构建发送邮件的实现

import com.bc.work.dto.MailDTO;
    import com.bc.work.service.MailService;
    import org.springframework.mail.MailSender;
    import org.springframework.mail.SimpleMailMessage;
    import javax.annotation.Resource;
    
    /**
     * 邮箱发送实现类
     */
    @Service
    @Component
    public class MailServiceImpl implements MailService {
    
        @Resource
        private MailSender mailSender;
    
        @Override
        public void send(MailDTO mailDTO) {
            MailDTO mailDTO=new MailDTO();
            mailDTO.setMailAccount("xxxx@163.com");
            mailDTO.setTitle("主题");
            mailDTO.setContent("内容");
    
    
            //new 一个简单邮件消息对象
            SimpleMailMessage message = new SimpleMailMessage();
            //和配置文件中的的username相同，相当于发送方
            message.setFrom("xxxx@163.com");
            //收件人邮箱
            message.setTo(mailDTO.getMailAccount());
            //标题
            message.setSubject(mailDTO.getTitle());
            //正文
            message.setText(mailDTO.getContent());
            //发送
            mailSender.send(message);
        }
    }
