话很少说，上代码--第一种，本身实现的，参考资料html

好了，一下是另一种的实现方式,首先要建立一个 mail.setting 的文件，在classpath（在标准Maven项目中为src/main/resources）的config目录下新建mail.setting文件，最小配置内容以下，在此配置下，smtp服务器和用户名都将经过from参数识别：参考---参考资料session
cn.hutool.extra.mail.MailUtil.send(CollUtil.newArrayList("13740519@qq.com"),
CollUtil.newArrayList("8040824@qq.com"),
CollUtil.newArrayList("timagi@163.com"),
"测试主题",
"<h1>邮件来自Hutool测试</h1>",
true);
# 邮件服务器的SMTP地址，可选，默认为smtp.<发件人邮箱后缀> host = smtp.qiye.163.com # 邮件服务器的SMTP端口，可选，默认25 port = 25 # 发件人（必须正确，不然发送失败） from = Tihui@pa.com # 用户名，默认为发件人邮箱前缀 user = Tihui@pa.com # 密码（注意，某些邮箱须要为SMTP服务单独设置密码，详情查看相关帮助） pass = Lo1313
