使用SpringBoot发送邮件

最后发送成功后,感觉SpringBoot真的很强大.

↑待加入email输入的重载(可以不上传文件或可以不填写主内容)

↑待加入邮箱RegExp,title长度判定.(等琐碎工作)

首先创建SpringBoot项目

>>使用eclipse构建Spring项目 https://blog.csdn.net/fantasic_van/article/details/79309665 (eclipse未测试)

>>IDEA构建SpringBoot项目 https://blog.csdn.net/lom9357bye/article/details/69677120

之后设置pom.xml文件 (红色是SpringBoot的邮件服务依赖)

<?xml version="1.0" encoding="UTF-8"?>

            </plugin>
        </plugins>
    </build>

</project>

这里我用的IDEA,等待它自动加载依赖完成.

在resource下的application.properties加入:

spring.mail.host=smtp.126.com
spring.mail.username=发送邮箱@126.com
spring.mail.password=客户端授权码
spring.mail.default-encoding=UTF-8
#spring.mail.port=25
#spring.mail.protocol=smtp
#server.port=8080

126邮箱的授权密码开启方式:

创建一个Contoller

package com.ykmimi;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

@RestController
@RequestMapping("mail")
public class MailController {
    @Autowired
    JavaMailSender mailSender;

    @RequestMapping("sendmail")
    public Object sendEmail(){

        try {
            final MimeMessage mimeMessage = this.mailSender.createMimeMessage();
            final MimeMessageHelper message = new MimeMessageHelper(mimeMessage);
            message.setFrom("发送邮箱@126.com");
            message.setTo("接收邮箱@qq.com");
            message.setSubject("测试邮件主题");
            message.setText("测试邮件内容");
            this.mailSender.send(mimeMessage);
        } catch (MessagingException e) {
            e.printStackTrace();
        } finally {
            return "sendEmail!";
        }

    }
}

之后执行测试类 SpringbootdemoApplication

浏览器执行  http://localhost:8080/mail/sendmail
