Springboot使用Hutool邮件工具发送邮箱验证码一、引入依赖因为Hutool对于第三方工具都是可选依赖，所以除了Hutool依赖还需要引入MailUtil的依赖 <dependency> <groupId>cn.hutool</groupId> <artifactId>hutool-all</artifactId> <version>5.5.0</version> </dependency> <dependency> 阅读详情



                public static string Send() {

            string result = "";

                SmtpClient smtp = new SmtpClient();

                smtp.Host = "smtp.163.com";//如果使用163发送 

                smtp.Credentials = new System.Net.NetworkCredential("duling509@163.com", "7889698");//邮箱账号与密码 

                smtp.Send(mail); 

            }

            catch (Exception ex) {

                result = ex.Message;

            }

            return result;

        }
