springboot开发发送邮件账号由前端填写

场景：用户登录时忘记密码，需要通过邮箱找回密码

1.创建springboot项目

2.pom导入依赖


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

3.application.properties配置文件


spring.mail.host=smtp.163.com
spring.mail.username=sple_vip@163.com//发件人邮箱，需要开启smtp服务
spring.mail.password=ming438434//授权密码，非邮箱的登录密码
spring.mail.port=25
spring.mail.protocol=smtp
spring.mail.default-encoding=UTF-8

发件人邮箱的设置：

邮箱客户端授权码也需要手动开启，设置授权码

4.用户输入自己的邮箱，点击找回，前端页面

html代码：


<div class="regWrap">
    <div class="regName">
        <span>请输入邮箱</span>
        <input id="mail" type="email" class="mail" placeholder="请输入邮箱">
    </div>
    <button id="registbtn" class="regBtn" type="button">找回</button>
</div>

js代码：


$(function () {
	$("#registbtn").click(function() {
		var user = {
				mail:$("#mail").val()
		}
		$.ajax({  
		    type: "POST",  
		    url:"/mail.action",
		    contentType: "application/json;",
		    data: JSON.stringify(user),
		    success: function (data) {
		    	if(data == "successful"){
		    		alert("已发送至您的邮箱")
		    		location.href="/login.html";
		    	}
		    	if (data=="failful") {
		    		alert("邮箱错误")
				}
		    },
		    error: function (data) {  
		            alert("网络繁忙")
		    }  
		});
		
	});
});

5.点击找回，进入controller层


@RequestMapping("/mail.action")
public String mail(@RequestBody User user) {
	return mailService.sendMail(user);
}

service层


@Service
public class MailServiceImpl implements MailService{
	@Autowired
	private JavaMailSender javaMailSender;
	@Autowired
	private UserMapper userMapper;
	@Override
	public String sendMail(User user) {
		User user2 = mailPwd(user);
		StringBuilder stringBuilder=new StringBuilder();
		stringBuilder.append("<html><head><title></title></head><body>");
		stringBuilder.append("亲爱的用户"+user2.getAccount()+",您的当前密码是："+user2.getPassword());
		stringBuilder.append("</br><a href='https://www.baidu.com/'>访问百度</a></body><html>");
		MimeMessage mimeMessage=javaMailSender.createMimeMessage();
		//multipart模式
		try {
			MimeMessageHelper mimeMessageHelper=new MimeMessageHelper(mimeMessage, true);
			mimeMessageHelper.setTo(user.getMail());//收件人邮箱user.getMail()
			mimeMessageHelper.setFrom("sple_vip@163.com");//发件人邮箱
			mimeMessage.setSubject("找回密码");
			//启用html
			mimeMessageHelper.setText(stringBuilder.toString(),true);
			javaMailSender.send(mimeMessage);
			return Constent.SUCCESSFUL;
		} catch (MessagingException e) {
			e.printStackTrace();
			return Constent.FAILFUL;
		}
	}
    
    /**
	 * 通过邮箱到数据库查询用户的信息
	 */
	@Override
	public User mailPwd(User user) {
		return userMapper.mailPwd(user);
	}
	
}

dao层


public interface UserMapper {
	/**
     * 通过邮箱查询用户信息
     */
	@Select("SELECT * FROM user WHERE mail = #{mail}")
	public User mailPwd(User user);
}
