本文實例為大家分享了springboot實現發送郵件的具體代碼，供大家參考，具體內容如下

1.引入依賴

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

2.找到qq郵箱，開啟smtp服務，這里生成你的密碼，復制第三步用

3.password里輸入你獲取到的密碼（重點：這里一定不能錯）

spring.mail.username=1550213743@qq.comspring.mail.password=********spring.mail.host=smtp.qq.com#開啟加密驗證spring.mail.properties.mail.smtp.ssl.enable=true

4.EmailApplicationTests類里進行測試， contextLoads為簡單的發送，僅限于文本。contextLoads2為復雜，可以發送圖片，html格式

package com.xyj;import org.junit.jupiter.api.Test;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.test.context.SpringBootTest;import org.springframework.mail.SimpleMailMessage;import org.springframework.mail.javamail.JavaMailSender;import org.springframework.mail.javamail.JavaMailSenderImpl;import org.springframework.mail.javamail.MimeMessageHelper;import javax.mail.MessagingException;import javax.mail.internet.MimeMessage;import java.io.File;@SpringBootTestclass EmailApplicationTests { @Autowired JavaMailSenderImpl mailSender; @Test void contextLoads() { SimpleMailMessage mailMessage = new SimpleMailMessage(); mailMessage.setSubject('你好'); mailMessage.setText('123456'); mailMessage.setTo('1550213743@qq.com'); mailMessage.setFrom('1550213743@qq.com'); mailSender.send(mailMessage); } @Test void contextLoads2() throws MessagingException { MimeMessage mimeMessage = mailSender.createMimeMessage(); MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true); helper.setSubject('你好'); helper.setText('<p style=’color:red’>這是紅色的</p>',true); helper.addAttachment('bg.jpg',new File('D:money網頁疫情imagesbg1.jpg')); helper.setTo('1550213743@qq.com'); helper.setFrom('1550213743@qq.com'); mailSender.send(mimeMessage); }}
