## 实现 ##

在上面成功实现发送简单邮件的基础上。

实现发送freemarker等模板文件邮件。

项目中引入模板相关依赖

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

在src/main/resource下的templates下新建模板文件show.html

<!DOCTYPE html>
    <html>
    <head>
    <meta charset="UTF-8">
    <title>测试</title>
    </head>
    <body>
     ${username}
    </body>
    </html>

service中新增方法

void sendTemplateEmail(String sendTo,String title,String show);

实现方法

//发送模板的邮件
     @Override
     public void sendTemplateEmail(String sendTo, String title, String show) {
      MimeMessage message =mailSender.createMimeMessage();
      try {
       
       MimeMessageHelper helper =new MimeMessageHelper(message,true);
       helper.setFrom(emailConfig.getEmailFrom());
       helper.setTo(sendTo);
       
       helper.setSubject(title);
       //封装模板使用的数据
       Map<String, Object> model = new HashMap<>();
       //这里的name要与模板中的一致
       model.put("username", "霸道流氓气质");
       
       //得到模板
       //模板名字与templates中的模板名字一致
       Template template = freeMarkerConfig.getConfiguration().getTemplate(show);
       String html = FreeMarkerTemplateUtils.processTemplateIntoString(template, model);
       
       helper.setText(html,true);
      } catch (Exception e) {
       e.printStackTrace();
      }
      mailSender.send(message);
     }

新建Controller中的方法

@RequestMapping("sendTemplateEmail")
     @ResponseBody
     public String sendTemplateEmail() {
      
      emailService.sendTemplateEmail("****@qq.com", "测试模板发送", "show.html");
      return "success";
     }

将代码中的发送以及要发送的邮箱以及授权码赋值后运行。

## 效果 ##

打开浏览器访问

[http://localhost:8080/sendTemplateEmail][http_localhost_8080_sendTemplateEmail]

等待返回success后
