实现用代码发送邮件的方式,这里选用QQ邮件。
参考:https://www.runoob.com/java/java-sending-email.html
1、pom.xml
<!--邮件-->
<!-- https://mvnrepository.com/artifact/com.sun.mail/javax.mail -->
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.6.2</version>
</dependency>
<!-- https://mvnrepository.com/artifact/javax.activation/activation -->
<dependency>
<groupId>javax.activation</groupId>
<artifactId>activation</artifactId>
<version>1.1.1</version>
</dependency>
2、准备邮箱账户
发送账号和接收账号
发送账号:
(1)需要开启IMAP、SMTP服务和Exchange服务
(2)需要生成授权码
3、代码
package com.skytreestudy.test;
import com.sun.mail.util.MailSSLSocketFactory;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.security.GeneralSecurityException;
import java.util.Properties;
public class EamilSend {
public static void main(String [] args) throws GeneralSecurityException
{
// 收件人电子邮箱
String to = "36xxxxxxx8@qq.com";
// 发件人电子邮箱
String from = "1xxxxx178@qq.com";
// 指定发送邮件的主机为 smtp.qq.com
String host = "smtp.qq.com"; //QQ 邮件服务器
// 获取系统属性
Properties properties = System.getProperties();
// 设置邮件服务器
properties.setProperty("mail.smtp.host", host);
properties.put("mail.smtp.auth", "true");
MailSSLSocketFactory sf = new MailSSLSocketFactory();
sf.setTrustAllHosts(true);
properties.put("mail.smtp.ssl.enable", "true");
properties.put("mail.smtp.ssl.socketFactory", sf);
// 获取默认session对象
Session session = Session.getDefaultInstance(properties,new Authenticator(){
@Override
public PasswordAuthentication getPasswordAuthentication()
{
//密码必须是生成的授权码,而不能是原密码
return new PasswordAuthentication(from, "kddxxxxxxxxa"); //发件人邮件用户名、密码
}
});
try{
// 创建默认的 MimeMessage 对象
MimeMessage message = new MimeMessage(session);
// Set From: 头部头字段
message.setFrom(new InternetAddress(from));
// Set To: 头部头字段
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
// Set Subject: 头部头字段
message.setSubject("This is the Subject Line!");
// 设置消息体
message.setText("This is actual message");
// 发送消息
Transport.send(message);
System.out.println("Sent message successfully....from runoob.com");
}catch (MessagingException mex) {
mex.printStackTrace();
}
}
}
一般来说,需要自己配置的就四处:
- 发送方
- 接收方
- 发送方授权码
- 标题和消息
接收消息:
