Springboot集成邮件服务

集成步骤

1. 添加starter依赖
2. 添加相关配置
3. 调用JavaMailSender发送邮件

添加starter依赖

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

添加相关配置

Gmail

选用了587端口。密码若直接使用google账号密码会提示使用应用专属密码，提示信息中有超链接，点开按流程设置即可获得专属密码

  spring.mail.host=smtp.gmail.com
  spring.mail.port=587
  spring.mail.username={google账号}@gmail.com
  spring.mail.password={google应用专属密码}
  spring.mail.properties.mail.smtp.auth=true
  spring.mail.properties.mail.smtp.starttls.required=true
  spring.mail.properties.mail.smtp.starttls.enable=true

QQ邮箱

开启SSL时使用587端口时无法连接QQ邮件服务器

  spring.mail.host=smtp.qq.com
  spring.mail.username={QQ号}@qq.com
  spring.mail.password={客户端授权码}
  spring.mail.properties.mail.smtp.auth=true
  spring.mail.properties.mail.smtp.port=465
  spring.mail.properties.mail.smtp.starttls.required=true
  spring.mail.properties.mail.smtp.starttls.enable=true

调用JavaMailSender发送邮件

JavaMailSender需要装配才可使用

@Configuration
public class EmailConfig {

    @Resource
    private JavaMailSender mailSender;

}

    /**
     * @param to 接收邮箱
     * @param subject 邮件主题
     * @param content 邮件正文
     */
    public void sendSimpleMail(String to, String subject, String content) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(from);
        message.setTo(to);
        message.setSubject(subject);
        message.setText(content);
        mailSender.send(message);
    }
