Springboot实现邮箱验证，发送邮件

首先，您需要打开电子邮件的第三方支持并获得授权代码

以QQ邮箱为例：

1.导入依赖

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

2.然后在项目application.yml

spring:  mail:    username: 您的QQ邮箱    password: 你的授权码    host: smtp.qq.com    properties:      mail.smtp.ssl.enable: true

3.编制测试方法进行测试

@RunWith(SpringRunner.class)@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)public class ShopsApplicationTests {    @Autowired    JavaMailSenderImpl mailSender;    @Test    public void contextLoads() throws MessagingException {        int count = 1;///默认发送一次        MimeMessage mimeMessage = mailSender.createMimeMessage();        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);        while (count-- != 0) {            String codeNum = "";            int[] code = new int[3];            Random random = new Random();            ///自动生成验证码            for (int i = 0; i < 6; i++) {                int num = random.nextInt(10) + 48;                int uppercase = random.nextInt(26) + 65;                int lowercase = random.nextInt(26) + 97;                code[0] = num;                code[1] = uppercase;                code[2] = lowercase;                codeNum += (char) code[random.nextInt(3)];            }            //标题            helper.setSubject(”你的验证码是:" + codeNum);            //内容            helper.setText("您好！，感谢您对小站的支持。，感谢您对小站的支持。您的验证码是：“ + "<h2>" + codeNum + "</h2>" + 千万不要告诉别人哦！", true);            ///邮件接收者            helper.setTo("123456789@qq.com");            //邮件发送者必须与配置文件中相同，否则，授权码无法匹配            helper.setFrom("987654321@qq.com");            mailSender.send(mimeMessage);        }    }

测试结果
