4.测试

@GetMapping("/sendtoqq")
    @Log("测试注解")
    public Result sendtoqq() {
        // 163
        String[] to = {"1135365@qq.com", "3654666661@outlook.com"};// 收件人

        List<File> files = new ArrayList<>();
        File file = new File("/Users/lizhenghang/Desktop/网上购物系统设计与实现.docx");
        files.add(file);
        EmailUtil.sendMailNoFrom(to, "测试标题to qq", "测试内容to qq", files);
        return Result.ok("发送成功！");
    }

    @GetMapping("/sendto163")
    @Log("测试注解")
    public Result sendto163() {
        String from = "11366669991@qq.com";// 发件人邮箱
        String[] to = {"186666468@163.com"};// 收件人邮箱，支持传
        String password = "tynmdlqdelfpjiha";
        String host = "smtp.qq.com";

        List<File> files = new ArrayList<>();
        File file = new File("/Users/lizhenghang/Desktop/网上购物系统设计与实现.docx");
        files.add(file);
        EmailUtil.sendMail(from, to, host, password, "测试标题11111 to 163", "测试内容11111 to 163", files);
        return Result.ok("发送成功！");
