代码简化，有需求可以联系

成果展示图

//获取验证码
在这里插入图片描述

配置

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

spring.mail.host=smtp.qq.com
spring.mail.username=999999999@qq.com//发送者邮箱
spring.mail.password=xkzoexejzkylbgah//发送者邮箱授权值
spring.mail.default-encoding=utf-8

spring.mail.password的取值方法
根据如图片操作–

服务层

接口

public interface EmailService {/*** toEmail 接收验证码的邮箱* text 主题* message 主体信息* */public boolean sendEmail(String toEmail, String text, String message);
}

实现类

@Service
public class EmailServiceImpl implements EmailService{@Resourceprivate JavaMailSender javaMailSender;@Value("${spring.mail.username}")private String fromEmail;@Overridepublic boolean sendEmail(String toEmail, String text, String message) {SimpleMailMessage simpleMailMessage = new SimpleMailMessage();//设置发件邮箱simpleMailMessage.setFrom(fromEmail);//收件人邮箱simpleMailMessage.setTo(toEmail);//主题标题simpleMailMessage.setSubject(text);//信息内容simpleMailMessage.setText(message);//执行发送try {//发送可能失败javaMailSender.send(simpleMailMessage);//没有异常返回true，表示发送成功return true;} catch (Exception e) {//发送失败，返回falsereturn false;}}
}

控制层

//发送到邮箱验证码 --获取验证码

	@Resourceprivate EmailService emailService;@ResponseBody@RequestMapping("getEmailCode")//通过httpsession来存入验证码值public String getEmail(String toEmail,HttpSession httpSession){Random random = new Random();//生成随机验证码int code=1000+random.nextInt(8999);//把验证码存储到session中httpSession.setAttribute("code", code);//执行发送验证码if(emailService.sendEmail(toEmail, "验证码","欢迎注册,您的验证码为:"+code)) {return "获取成功";}return "获取失败";}

//邮箱接收到的验证码与输入的验证码进行比较

@RequestMapping("checkEmailCode")@ResponseBodypublic String checkEmailCode(String code,HttpSession httpSession) {String emailCode = httpSession.getAttribute("code").toString();if(emailCode!=null) {if(emailCode.equals(code)) {return "校验成功";}}return "校验失败";}

前端

//输入框–按钮

<input name="name" type="text" placeholder="邮箱" id="usernameid" />
<input name="code" type="text" placeholder="邮箱" id="codeid" /><input type="button" id="btn-get" value="获取验证码" onclick="doGetEmailCode()" />
<input type="button" id="btn-compare" value="验证验证码" onclick="doCompareEmailCode()" />

//发送验证码

function doGetEmailCode() {var email = $("#usernameid").val();//获取接收验证码的邮箱var url = "getEmailCode?toEmail=" + email;//地址与邮箱拼接$.get(url, function(result) {console.log("result", result); });
}

//验证验证码

function doCompareEmailCode() {var codeid = $("#codeid").val();var url = "checkEmailCode?code=" + codeid;$.get(url, function(result) {console.log(result);});
}
