目录
一、springboot整合javaMail
(1)导入依赖:
(2)做配置
(3)邮件客户端
二、发送复杂文件
org.springframework.boot
spring-boot-starter-mail
spring:
mail:
host: smtp.qq.com #邮件服务器供应商
username: 129*****328@qq.com
password: jcf****fb
password到对应的供应商邮箱开启smtp配置和pop3配置
qq邮箱为:设置——>
点击开启会查询邮件确认生份,确认生份后便可获得该密码。
package com.example.demo.service.impl;
import com.example.demo.service.SendMail;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;
@Service
public class SendMailImpl implements SendMail {
@Autowired
private JavaMailSender javaMailSender;
//发送人
private String from="129******328@qq.com";
//接收人
private String to="wu*****@163.com";
//标题
private String subject="测试邮件";
//正文
private String text="邮件正文内容";
@Override
public void sendMail() {
SimpleMailMessage message=new SimpleMailMessage();
message.setFrom(from+"(大表哥)");//后面的为名称
message.setTo(to);
message.setSubject(subject);
message.setText(text);
// message.setSentDate();//定时发送
javaMailSender.send(message);
}
}
JavaMailSender对象是spring容器里添加依赖后生成的,可直接注入使用。
SimpleMailMessage对象里可添加信息,基本信息如上。
使用该方法便可以发送到目的邮箱了!
配置和简单文件发送一样,业务层如下
package com.example.demo.service.impl;
import com.example.demo.service.SendMail;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Service;
import javax.mail.internet.MimeMessage;
import java.io.File;
@Service
public class SendMailImpl2 implements SendMail {
@Autowired
private JavaMailSender javaMailSender;
//发送人
private String from = "12**328@qq.com";
//接收人
private String to = "wu******@163.com";
//标题
private String subject = "测试邮件";
//正文
private String text = "点开有惊喜";
@Override
public void sendMail() {
try {
MimeMessage message = javaMailSender.createMimeMessage();
//设置为true代表允许上传附件
MimeMessageHelper helper = new MimeMessageHelper(message,true);
helper.setFrom(from + "(大表哥)");
helper.setTo(to);
helper.setSubject(subject);
//设置为true代表允许发送html文本
helper.setText(text, true);
//发送附件
File f1 = new File("C:\\Users\\Gragon wu\\Desktop\\网站.txt");
File f2 = new File("C:\\Users\\Gragon wu\\Desktop\\捕获.PNG");
helper.addAttachment(f1.getName(), f1);
helper.addAttachment("第二个文件.png", f2);
javaMailSender.send(message);
} catch (Exception e) {
e.printStackTrace();
}
}
}
这里使用了MimeMessage对象和MimeMessageHelper对象来实现。
