一、前期工作
1.开启邮箱服务
开启邮箱的POP3/SMTP服务(这里以qq邮箱为例,网易等都是一样的)
2.导入依赖
在springboot项目中导入以下依赖:
3.配置application.yaml文件
# 邮箱设置spring: mail: host: smtp.163.com //如果是qq的邮箱就是smtp.qq.com password: 开启pop3生成的一个字符串密码 username: 自己的邮箱地址,是什么邮箱后缀就是什么。 port: default-encoding: UTF-8 protocol: smtp properties: mail.smtp.auth: true mail.smtp.starttls.enable: true mail.smtp.starttls.required: true mail.smtp.socketFactory.class: javax.net.ssl.SSLSocketFactory mail.smtp.socketFactory.fallback: false mail: smtp: ssl: enable: true mvc: pathmatch: matching-strategy: ant_path_matcher datasource: # jdbc数据库设置 druid: password: sql密码 username: sql用户 url: jdbc:mysql://localhost:3306/sys?charsetEncoding=utf-8&useSSL=false driver-class-name: com.mysql.jdbc.Driver db-type: com.alibaba.druid.pool.DruidDataSourcemybatis: #mybatis的配置 type-aliases-package: com.cheng.springcolud.pojo config-location: classpath:mybatis/mybatis-config.xml mapper-locations: classpath:mybatis/mapper/*.xml
二、实现流程
1.导入数据库
/*
Navicat Premium Data Transfer
Source Server : likai
Source Server Type : MySQL
Source Server Version : 50719
Source Host : localhost:3306
Source Schema : sys
Target Server Type : MySQL
Target Server Version : 50719
File Encoding : 65001
Date: 04/06/2022 14:08:29
*/
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;
-- ----------------------------
-- Table structure for useremaillogintable
-- ----------------------------
DROP TABLE IF EXISTS `useremaillogintable`;
CREATE TABLE `useremaillogintable` (
`id` int(255) NOT NULL AUTO_INCREMENT,
`email` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`VerificationCode` int(20) NULL DEFAULT NULL,
`createTime` datetime(0) NULL DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP(0),
PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 4 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;
SET FOREIGN_KEY_CHECKS = 1;
2.后端实现
编写实体类
代码如下(示例):
@Data
@NoArgsConstructor
@ToString
public class EmailVerification {
private int id;
private String email; //需要发送的邮箱
private Integer verificationCode;//验证码
private Date createTime;
public EmailVerification(String email, Integer verificationCode) {
this.email = email;
this.verificationCode = verificationCode;
}
}
编写工具类ResultVo
@Data
@AllArgsConstructor
@NoArgsConstructor
public class ResultVO {
private int code;//相应给前端的状态码
private String msg;//相应给前端的提示信息
private Object data;//响应给前端的数据
}
编写dao层接口
Mapper
@Repository
public interface EmailVerificationDao {
/*将短信验证码和个人邮箱保存到数据库中*/
public Boolean getEmailVerificationCode(String email,Integer verificationCode);
/*校验短信信息*/
public List
/*查询所有的用户*/
public List
}
配置dao层接口的数据库操作
insert into sys.useremaillogintable(email, VerificationCode,createTime) VALUES (#{email},#{verificationCode},NOW())
select * from sys.useremaillogintable where email=#{email} and VerificationCode=#{verificationCode}
select * from sys.useremaillogintable;
编写service层接口
public interface EmailVerificationCodeService {
public boolean getEmailVerificationCode(String email,Integer verificationCode);
public ResultVO checkEmailVerificationCode(String email, Integer verificationCode);
public ResultVO queryEmailVerificationInfo();
public ResultVO sendEmailVerificationCode(String email);
}
代码讲解: getEmailVerificationCod方法是将数据(验证码和邮箱地址)放入数据库当中,checkEmailVerificationCode是用来校验其验证码和邮箱是否是正确,·queryEmailVerificationInfo·是用来查询所有的数据,在这里我新加了个接口叫做senEmailVerificationCode就是单纯用来发送短信信息的,只有一个参数,他是没有相对应的数据库操作的。
编写service层的实现方法
@Service
public class EmailVerificationCodeServiceImpl implements EmailVerificationCodeService{
@Autowired
EmailVerificationDao emailVerificationDao;
private final static String EmailFrom = "li3122456997@163.com";
private final JavaMailSenderImpl javaMailSender;
public int code = (int)(Math.random() * 9000 + 1000);
public EmailVerificationCodeServiceImpl(JavaMailSenderImpl javaMailSender) {
this.javaMailSender = javaMailSender;
}
@Override
public boolean getEmailVerificationCode(String email,Integer verificationCode) {
verificationCode =code;
return emailVerificationDao.getEmailVerificationCode(email,verificationCode);
}
@Override
public ResultVO checkEmailVerificationCode(String email, Integer verificationCode) {
List
if (emailVerifications.size()>0){
return new ResultVO(1001,"校验成功",emailVerifications);
}else {
return new ResultVO(1002,"校验失败",null);
}
}
@Override
public ResultVO queryEmailVerificationInfo() {
List
return new ResultVO(1001,"success",emailVerifications);
}
@Override
public ResultVO sendEmailVerificationCode(String email) {
SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
simpleMailMessage.setSubject("验证码");
simpleMailMessage.setTo(email);//收件人
simpleMailMessage.setText("验证码为:"+code);
simpleMailMessage.setFrom("******@163.com"); //发送的人(写自己的)
javaMailSender.send(simpleMailMessage);
boolean emailVerificationCode = getEmailVerificationCode(email, code);
if (emailVerificationCode){
return new ResultVO(1001,"发送成功!","验证码为:"+code);
}else {
return new ResultVO(1002,"发送失败",null);
}
}
}
代码讲解: 这里就一个注重点,就是sendEmailVerificationCode的实现,我将随机数给提出出来,因为getEmailVerificationCode也是需要将随机数给保存到数据库当中的,为了避免两者的验证码不同,我就给其提取出来,以确保其一致性,在sendEmailVerificationCode的实现,我在里面调用了getEmailVerificationCode方法,这样可以保证其邮箱地址的一致性。在通过判断,验证短信是否发送成功。
实现controller层
@RestController
@CrossOrigin//允许回复前端数据,跨域请求允许
public class EmailController {
@Autowired
EmailVerificationCodeService emailVerificationCodeService;
@Autowired
InfoTimingSendServiceImpl infoTimingSendService;
@GetMapping("send")
public ResultVO sendMail(@RequestParam(value = "email") String email){
return emailVerificationCodeService.sendEmailVerificationCode(email);
}
@GetMapping("checkEmailVerification")
public ResultVO checkEmail(@RequestParam(value = "email") String email, @RequestParam(value = "verificationCode") Integer verificationCode){
ResultVO resultVO = emailVerificationCodeService.checkEmailVerificationCode(email, verificationCode);
return resultVO;
}
@GetMapping("queryAll")
public ResultVO queryAll(){
ResultVO resultVO = emailVerificationCodeService.queryEmailVerificationInfo();
return resultVO;
}
}
注意: 需要加入@CrossOrigin注解,这个注解是可以解决跨域问题,这个项目我写的是前后端分离的,所以这里需要加入这个在注解,为后面通过axios来获取数据做准备
Test代码
@SpringBootTest
class DemoApplicationTests {
@Autowired
EmailVerificationCodeService emailVerificationCodeService;
@Autowired
InfoTimingSendServiceImpl infoTimingSendService;
@Test
void contextLoads() {
ResultVO aBoolean = emailVerificationCodeService.checkEmailVerificationCode("***@qq.com", 8001);
System.out.println(aBoolean);
}
@Test
void infoSendTest(){
infoTimingSendService.infoSend();
}
@Test
void send(){
final ResultVO resultVO = emailVerificationCodeService.sendEmailVerificationCode("***7@qq.com");
System.out.println(resultVO);
}
}
前端页面的实现
注意: 在前端页面我使用了bootstrap框架,vue,axios,所以需要当如相对应的包
注册页面
登录
{{tips}}
var baseUrl="http://localhost:8080/";
var vm = new Vue({
el:'#container',
data:{
info: 'send out',
time: 60,
verification_send: true,
verification:"",
email:"",
tips:""
},
methods:{
send:function (){
var url1 = baseUrl+"/send";
axios.get(url1,{params:{email:vm.email}}).then((res)=>{
console.log(res);
if(res.data.code==1001){
vm.tips="发送成功!";
}else{
vm.tips="发送失败!请稍后再试"
}
});
setInterval(function(){
if(vm.time==60){
vm.time--;
this.time=vm.time;
vm.verification_send = false;
console.log(vm.time);
}else if(vm.time==0){
clearInterval(vm.time)
vm.verification_send = true;
}else{
vm.time--;
console.log(vm.time);
}
},1000);
},
sign:function(){
var url = baseUrl+"/checkEmailVerification";
if(vm.email==""&&vm.verification==""){
vm.tips="请输入验证码或邮箱!";
}else{
axios.get(url,{params:{email:vm.email,verificationCode:vm.verification}})
.then((res)=>{
var vo = res.data;
if(vo.code==1001){
vm.tips="登录成功";
setInterval(function(){
window.location.href="index.html" rel="external nofollow" ;
},3000);
}else{
vm.tips="请输入正确的验证码!";
}
})
}
}
}
})
讲解:在这里,在发送按钮上面加入了时间倒计时,当我点击的时候,会倒计时1minute,在这期间,发送按钮是无法被点击的!这就避免了多次放松

总结
以上就是springboot+vue实现后端和前端短信发送的所有代码,其实像短信发送了两次,以第二次为准的话,我们可以实现一个数据库内容的修改,当其发送了两次,我们就以第二次为准!希望对大家有所帮助,这里前端的验证其实是不够完善的,我没有去加入邮箱的验证。是因为我的QQ邮箱被腾讯被封了,我害怕试多了之后,网易邮箱也被封了!!!!
