1、引入依赖
<!--邮件-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
2、配置地址
spring: mail: # 配置 SMTP 服务器地址 host: mail.xxxx.com # 发送者邮箱 username: xxx@xxx.com # 配置密码，注意不是真正的密码，而是刚刚申请到的授权码 password: xxxxxxx # 端口号465或587 port: 25 # 默认的邮件编码为UTF-8 default-encoding: UTF-8 # 配置SSL 加密工厂 properties: mail: smtp: socketFactoryClass: javax.net.ssl.SSLSocketFactory #表示开启 DEBUG 模式，这样，邮件发送过程的日志会在控制台打印出来，方便排查错误 debug: true
3、编写邮件类
package com.hiscene.has.sys.mail.service.impl; import com.hiscene.has.sys.mail.service.MailService; import com.hiscene.util.ThreadPoolUtil; import freemarker.template.Configuration; import freemarker.template.Template; import lombok.SneakyThrows; import lombok.extern.slf4j.Slf4j; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.core.io.ResourceLoader; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.mail.javamail.MimeMessageHelper; import org.springframework.stereotype.Service; import javax.mail.internet.MimeMessage; import java.util.HashMap; import java.util.concurrent.ThreadPoolExecutor; @Service @Slf4j public class MailServiceImpl implements MailService { @Autowired private JavaMailSender javaMailSender; @Autowired ResourceLoader resourceLoader; @Value("${spring.mail.username}") private String sender; @SneakyThrows @Override public Boolean sendSimpleMail(String receiver, String subject, String username, String pwd) { try { //创建message MimeMessage message = javaMailSender.createMimeMessage(); MimeMessageHelper helper = new MimeMessageHelper(message, true); // //发件人 helper.setFrom( "发邮件中文名称"+" <"+sender+">"); //收件人 helper.setTo(receiver); //标题 helper.setSubject(subject); HashMap map = new HashMap(); map.put("username", username); //解析模板并替换动态数据，最终username将替换模板文件中的${username}标签。 String contents = "<html><body>"+username+"<br>"+ pwd + "</body></html>"; helper.setText(contents, true); //发送邮件 javaMailSender.send(message); return true; } catch (Exception e) { return false; } } }
