補充發送html郵件Spring Boot支持使用HTML發送郵件是通過MimeMessage來完成的 。
發送帶附件的郵件MimeMessageHelper支持發送復雜郵件模板，支持文本、附件、HTML、圖片等 。比如需要發送附件 ， 則在上面的代碼中通過調用helper的addAttachment(fileName, file)方法即可 。
例:發送HTML郵件package com.example.emaildemo.controller;import com.example.emaildemo.service.MailService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;/** * 測試郵件發送 * @author galaxy */@RestControllerpublic class SendMailController {@Autowiredprivate MailService mailService;/*** 發送HTML郵件* @param to* @param subject* @param content*/@RequestMapping("/sendHtmlMailMessage")public void sendHtmlMailMessage(String to,String subject,String content){mailService.sendHtmlMailMessage(to,subject,content);}}
