1.引入依賴(lài)

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

2.找到qq郵箱礼患，開(kāi)啟smtp服務(wù)碌宴，這里生成你的密碼个曙，復(fù)制第三步用

3.password里輸入你獲取到的密碼（重點(diǎn)：這里一定不能錯(cuò)）

spring.mail.username=1550213743@qq.com
spring.mail.password=********
spring.mail.host=smtp.qq.com
#開(kāi)啟加密驗(yàn)證
spring.mail.properties.mail.smtp.ssl.enable=true

4.EmailApplicationTests類(lèi)里進(jìn)行測(cè)試察郁， contextLoads為簡(jiǎn)單的發(fā)送，僅限于文本轩缤。contextLoads2為復(fù)雜命迈，可以發(fā)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;

@SpringBootTest
class 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(wǎng)頁(yè)\\疫情\\images\\bg1.jpg"));
        helper.setTo("1550213743@qq.com");
        helper.setFrom("1550213743@qq.com");
        mailSender.send(mimeMessage);
    }

}
