springboot实现邮件发送的功能

## springboot实现邮件发送的功能 ##

1.引入依赖

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

2.在application.properties配置(这里以网易邮箱为例)  
usename为你的邮箱  
password为你的邮箱的客户端授权密码,这个需要自己去设置的,不是你邮箱的登录密码

spring.mail.host=smtp.163.com
    spring.mail.username=xxxxxxx@163.com
    spring.mail.password=xxxxxxxx #开启POP3之后设置的客户端授权码
    spring.mail.protocol=smtp
    spring.mail.default-encoding=UTF-8

3.相关代码:(这里不仅仅是写测试类,模拟用户从页面发起请求)  
①controller

@Controller
    public class SendEmailController { 
    
        @Autowired
        private IEmailService emailService;
        /** * 发送验证邮箱 * * @param email * @return */
        @RequestMapping("sendEmail")
        @ResponseBody
        public AjaxResult sendEmail(String email) { 
            AjaxResult json = new AjaxResult();
            this.emailService.sendVerifyEmail(email, UserContext.getCurreentUser().getId());
            return json;
        }
    
    
    }

②service实现类

@Service
    public class EmailServiceImpl implements IEmailService{ 
    	@Autowired
    	private IUserInfoService userinfoService;
    	@Autowired
    	private JavaMailSender javaMailSender;
    	@Autowired
    	private MailVerifyMapper mailVerifyMapper;
    	@Value("${spring.mail.host}")
    	private String host;
    	@Value("${spring.mail.username}")
    	private String username;
    	@Value("${spring.mail.password}")
    	private String password;
    	@Override
    	public void sendVerifyEmail(String email,Long userId) { 
    		UserInfo current = this.userinfoService.get(userId);
    		if (!current.getIsBindEmail()) { 
    			// 发送验证邮箱
    			// 1,创建一个邮箱验证对象;
    			MailVerify mVerify = new MailVerify();
    			mVerify.setEmail(email);
    			mVerify.setSendTime(new Date());
    			mVerify.setUserId(userId);
    			// 2,生成一个uuid;
    			mVerify.setUuid(UUID.randomUUID().toString());
    			// 3,构造邮件内容;
    			StringBuilder sb = new StringBuilder(100).append("这是一封验证邮件,请点击<a href='").append("/bindEmail?uuid=").append(mVerify.getUuid()).append("'>这里</a>完成验证,有效期为").append(Consts.EMAIL_VAILED_DAY).append("天");
    			// 4,发送邮件;
    			//System.out.println(sb);
    			try { 
    				JavaMailSenderImpl senderImpl = new JavaMailSenderImpl();
    				senderImpl.setHost(host);
    				senderImpl.setUsername(username);
    				senderImpl.setPassword(password);
    				//建立邮件消息,发送简单邮件和html邮件的区别
    				MimeMessage mailMessage = senderImpl.createMimeMessage();
    				MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage,"utf-8");
    				//设置收件人，寄件人
    				messageHelper.setTo(email);
    				messageHelper.setFrom(username);
    				messageHelper.setSubject("测试HTML邮件！");
    				messageHelper.setText(sb.toString(),true);
    				Properties prop= new Properties();
    				//将这个参数设为true，让服务器进行认证,认证用户名和 密码是否正确
    				prop.put("mail.smtp.auth","true");
    				//设置超时时间
    				prop.put("mail.smtp.timeout", "25000");
    				senderImpl.setJavaMailProperties(prop);
    				//发送邮件
    				senderImpl.send(mailMessage);
    				this.mailVerifyMapper.insert(mVerify);
    			} catch (MessagingException e) { 
    				throw  new RuntimeException("发送邮件失败");
    			}
    		}
    	}
    }

js如下:具体页面没有写出

这里为了安全,设置了UUID,通过UUID去数据库查询数据  
打印出来的请求是:

这是一封验证邮件,请点击<a href='http://localhost:8080/bindEmail?uuid=a6552eab-da64-4824-aeb4-c632ac3b94fd'>这里</a>完成验证,有效期为5天

4.邮箱中收到的效果如下:

5.当你在点击"这里"时,会跳往一个页面,也就是确认绑定邮箱

业务逻辑如下:  
①controller

/** * 绑定邮箱 */
        @RequestMapping("bindEmail")
        public String bindEmail(String uuid, Model model) { 
            try { 
                this.userInfoService.bindEmail(uuid);
                model.addAttribute("success", true);
            } catch (Exception e) { 
                model.addAttribute("success", false);
                model.addAttribute("msg", e.getMessage());
            }
            return "checkmail_result";
        }

②service实现类

@Override
        public void bindEmail(String uuid) { 
            // 根据uuid得到邮箱验证对象
            MailVerify mv = this.mailVerifyMapper.selectByUUID(uuid);
            if (mv != null) { 
                UserInfo userinfo = this.get(mv.getUserId());
                if (!userinfo.getIsBindEmail()// 判断1,用户是否绑定邮箱;
                        && DateUtil.getSecondsBetween(mv.getSendTime(), new Date()) <= Consts.EMAIL_VAILED_DAY * 24
                        * 3600) { 
                    // 判断1,用户是否绑定邮箱;2,在有效期之内
                    // 设置邮箱,并设置状态码
                    userinfo.setEmail(mv.getEmail());
                    userinfo.addState(BitStatesUtils.OP_BIND_EMAIL);
                    this.update(userinfo);
                    return;
                } else { 
                    throw new RuntimeException("超过有效期!");
                }
            } else { 
                throw new RuntimeException("绑定错误!");
            }
        }

③网页内容

<div class="container"  style="min-height: 343px;">  
    		<h1>
    			<#if success??>
    				您的邮件已经成功激活,请登录系统查看!
    			<#else>
    				您的邮件激活失败,失败原因是:${ msg}!
    			</#if>
    		</h1>
    	</div>
