springBoot发送邮箱验证码

一、在pom文件中添加依赖

　

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

 

二、配置yaml文件

这里在yaml文件中配置好参数后，springboot会自动装配配置的邮箱参数。

spring:
mail:
host: smtp.qq.com #邮箱服务器地址
username: ******@qq.com #邮箱账号
password: laxoyuoaxatjigef    #邮箱密码
default-encoding: utf-8    #默认编码

 

三、邮箱发送

package com.springBoot.learn.firstProject.manager.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.stereotype.Service;

import com.springBoot.learn.firstProject.manager.SendCodeManager;

@Service
public class SendCodeImp implements SendCodeManager {
@Autowired
JavaMailSenderImpl mailSender;
@Value("${spring.mail.username}")
private String form;



@Override
public String sendMail(String to, String subject) throws Exception{
String code = getNumber();
SimpleMailMessage message = new SimpleMailMessage();
message.setSubject(subject);
message.setText("注册验证码是：" + code);
message.setTo(to);
message.setFrom(form);
//message.setFrom(to);
mailSender.send(message);
return code;
}
/**
* 生成6位随机验证码
* @return
*/
public static String getNumber(){
String str = "1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ";
String code = "";
for(int i= 0;i<6;i++){
int index = (int)(Math.random()*str.length());
code+=str.charAt(index);
}
return code;
}
}
