Java实现简单邮件发送功能
本文实例为大家分享了Java实现简单邮件发送的具体代码，供大家参考，具体内容如下
需要的jar包:
- activation-1.1.1.jar
- mail-1.4.7.jar
QQ邮箱设置开启POP3/SMTP服务,并获得授权码
java实现简单邮件发送
import com.sun.mail.util.MailSSLSocketFactory;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;
public class Mail1 {
public static void main(String[] args) throws Exception {
//要发送邮件,需要获得协议和支持!开启服务POP3/SMTP服务 授权码: fsxqGovorymigfeb
Properties prop=new Properties();
prop.setProperty("mail.host","smtp.qq.com");//设置QQ邮件服务器
prop.setProperty("mail.transport.protocol","smtp");//设置邮箱发送协议
prop.setProperty("mail.smtp.auth","true");//需要验证用户名密码
//QQ邮箱还有设置SSL加密
MailSSLSocketFactory sf=new MailSSLSocketFactory();
sf.setTrustAllHosts(true);
prop.put("mail.smtp.ssl.enable","true");
prop.put("mail.smtp.ssl.socketFactory",sf);
//1.创建定义整个应用程序所需要的环境信息的Session对象
Session session=Session.getDefaultInstance(prop, new Authenticator() {
@Override
protected PassWordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("1369410772@qq.com","fsxqgovorymigfeb");
}
});
//开启session的debug模式,这样就可以查看运行状态了
session.setDebug(true);
//2.通过session对象获得transport对象
Transport transport = session.getTransport();
//3.使用邮箱的用户名和授权码连上邮件服务器
transport.connect("smtp.qq.com","1369410772@qq.com","fsxqgovorymigfeb");
//4.创建邮件:写邮件
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress("1369410772@qq.com"));//发件人
message.setRecipient(Message.RecipientType.TO,new InternetAddress("1369410772@qq.com"));//收件人
message.setSubject("你好");//邮件主题
message.setContent("<h1 style='color: red'>你好</h1>","text/html;charset=utf-8");//邮件内容
//5.发送邮件
transport.sendMessage(message,message.getAllRecipients());
//6.关闭连接
transport.close();
}
}java实现复杂邮件发送( 带文件 )
import com.sun.mail.util.MailSSLSocketFactory;
import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.mail.*;
import javax.mail.internet.InternetAddress;

message.setSubject("你好");//邮件主题
//message.setContent("<h1 style='color: red'>你好</h1>","text/html;charset=utf-8");//邮件内容
//=============================================================================
//带图片的内容
MimeBodyPart image = new MimeBodyPart();
DataHandler dh = new DataHandler(new FileDataSource("E:\\idea\\javaweb\\mail-java\\src\\tx.png"));//图片需要经过数据处理... DataHandler:数据处理
image.setDataHandler(dh);//在Body中放入处理的图片数据
image.setContentID("tx.png");//给图片设置ID
//准备正文数据
MimeBodyPart text = new MimeBodyPart();
text.setContent("这是一封邮件正文带图片<img data-original="cid:tx.png">的邮件","text/html;charset=utf-8");
//描述数据关系
MimeMultipart mm = new MimeMultipart();
mm.addBodyPart(text);
mm.addBodyPart(image);
mm.setSubType("mixed");
//设置到消息中,保存修改
message.setContent(mm);
message.saveChanges();
//=========================================================================
//5.发送邮件
transport.sendMessage(message,message.getAllRecipients());
//6.关闭连接
transport.close();
}
}Spring实现
1、添加依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>2、编写配置文件
spring.mail.username=1369410772@qq.com
spring.mail.password=fsxqgovorymigfeb
spring.mail.host=smtp.qq.com
spring.mail.properties.mail.smtp.ssl.enable=true3、编写测试类
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.File;
@SpringBootTest
class DemoApplicationTests {//简单邮件
@Autowired
JavaMailSenderImpl mailSender;
@Test
void contextLoads() {
//发送邮件
//收件人
//内容
SimpleMailMessage message = new SimpleMailMessage();
message.setSubject("测试");
message.setText("Hello");
message.setFrom("1369410772@qq.com");
message.setTo("1369410772@qq.com");
mailSender.send(message);
}
@Test
public void test2() throws Exception {//复杂邮件
MimeMessage mimeMessage = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
helper.setSubject("测试");
helper.setText("Hello",true);
//附件
helper.addAttachment("1.jpg",new File(""));
helper.setFrom("1369410772@qq.com");
helper.setTo("1369410772@qq.com");
mailSender.send(mimeMessage);
}
