springboot整合邮件发送

一、yml

mail:
host: smtp.qq.com
username: 发件人邮箱
password: SMTP授权密码
port: 25
protocol: smtp
default-encoding: UTF-8

二、pom

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

        </dependency>

三、service

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Service;

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


@Service
public class MailService {
    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    @Value("${spring.mail.username}")
    private String from;

    @Autowired
    private JavaMailSender mailSender;

    /**
     * 简单文本邮件
     * @param to 接收者邮件
     * @param subject 邮件主题
     * @param contnet 邮件内容
     */
    public void sendSimpleMail(String to, String subject, String contnet){

        SimpleMailMessage message = new SimpleMailMessage();
        message.setTo(to);
        message.setSubject(subject);
        message.setText(contnet);
        message.setFrom(from);

        mailSender.send(message);
    }




}

四、controller层调用，将参数传进去
