    }

}

在templates下建立email.html:

<!DOCTYPE html>
<html lang="zh" xmlns:th="http://www.thymeleaf.org">
    <head>
        <meta charset="UTF-8"/>
        <title>Title</title>
    </head>
    <body>
        <h4 th:text="|尊敬的:${username} 用户：|"></h4><br /><br />

       &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;恭喜您入住xxx平台VIP会员,您将享受xxx优惠福利，同时感谢您对xxx的关注与支持并欢迎您使用xx的产品与服务。<br />
       &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;...
    </body>
</html>

vue前台:

 <el-button type="primary" icon="edit"   v-if="hasPerm('sp:sendSimpleEmail')" @click="sendemail(scope.$index)">发邮件</el-button>


methods:{
    sendemail($index){
          var ids = [];
          sels.forEach(element => {
          ids.push(element.id);
         });

      var id = ids.join(",");

      this.$confirm("你确定要发邮件吗?", "提示")
        .then(() => {
          var url = this.HOST + "/sp/sendSimpleEmail";
          this.$axios
            .post(url, {
              id
            })
            .then(dara => {
              console.log(dara);
              this.getList();
              this.dialogFormVisible = false;
            });
        })
        .catch(() => { });
    }

}

后台运行结果:

页面效果:

直接回复邮件效果:
