Springboot-JavaMailSender发送邮件

1、引入pom依赖：分别是freemarker邮件模板和spring-maill依赖

<!-- Spring Boot Freemarker 依赖，发送HTML格式的邮件的方式 -->        
<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
<dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context-support</artifactId>
        <version>4.2.6.RELEASE</version>
</dependency>
<!-- spring-boot-mail 发送邮箱 -->	
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
<dependency>
        <groupId>javax.mail</groupId>
        <artifactId>mail</artifactId>
        <version>1.4.7</version>
</dependency>

 

2、在application.properties加入配置

#支持qq邮箱 163邮箱等
spring.mail.host=smtp.yeah.net
#发送者邮箱需要和实际发送者一致，否则报错501
spring.mail.username=PMDIDE@yeah.net
#发送者邮箱的授权码，不是密码，去对应邮箱设置
spring.mail.password=******
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true

 设置授权码：

 

3、发送邮件实现部分

@Override
    public String sendPasswordEmail(HttpServletRequest request, HttpServletResponse response) {
        String errorMsg="none";
        //验证码判断 
        if(request.getParameter("token").equals(request.getSession().getAttribute(Constants.KAPTCHA_SESSION_KEY).toString())){
            User thisUser=this.userRepository.findOneByEmail(request.getParameter("email"));
            if(thisUser!=null){
                //设置找回流程
                try{
                    String contextPath=request.getContextPath();
                    String base_url=request.getServerName().toString()+":"+request.getServerPort();
                    if(contextPath!=null && contextPath.length()>0){
                        base_url=base_url+contextPath;
                    }
                    
                    thisUser.setResetmark((UUID.randomUUID().toString().replace("-","")));
                    //过期时间
                    Calendar c = Calendar.getInstance();
                    c.setTime(new Date());
                    c.add(Calendar.MINUTE, 10);
                    thisUser.setResettime(c.getTime());
                    this.userRepository.save(thisUser);
                    ///邮件的内容
                    StringBuffer sb=new StringBuffer("PM-IDE<br/>");
                    sb.append("XXXXX<br/>");
                    sb.append("点击下面链接重设密码，请在10分钟内完成！<br/>");
                    sb.append("<a href=\"http://"+base_url+"/password/reset/");
                    sb.append(thisUser.getUsername());
                    sb.append("/");
                    sb.append(thisUser.getResetmark());
                    sb.append("/");
                    sb.append("\">http://"+base_url+"/password/reset/");
                    sb.append(thisUser.getUsername());
                    sb.append("/");
                    sb.append(thisUser.getResetmark());
                    sb.append("/");
                    sb.append("</a>");

                    //邮件信息
                    MimeMessage mimeMessage = mailSender.createMimeMessage();
                    MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
                    helper.setFrom(fromEmail);
                    helper.setTo(thisUser.getEmail());
                    helper.setSubject("科研项目管理系统");
                    helper.setText(sb.toString(), true);

                    //发送邮件
                    mailSender.send(mimeMessage);
                }catch(Exception e){
                    errorMsg="error";
                }
            }
            else{
                errorMsg="email";
            }
        }
        else{
            errorMsg="token";
        }
        return errorMsg;
    }
