您好!要在Java中连接电子邮件服务器,您可以使用JavaMail API。以下是一个简单的示例代码,用于连接到SMTP服务器并发送电子邮件:
```java
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;
public class EmailSender {
public static void main(String[] args) {
// 邮件配置信息
String host = "smtp.example.com"; // SMTP服务器地址
String username = "your_username"; // 发件人邮箱用户名
String password = "your_password"; // 发件人邮箱密码
// 邮件内容
String fromEmail = "sender@example.com"; // 发件人邮箱
String toEmail = "recipient@example.com"; // 收件人邮箱
String subject = "Hello, JavaMail!"; // 邮件主题
String body = "This is a test email sent from JavaMail."; // 邮件正文
// 设置邮件服务器属性
Properties props = new Properties();
props.put("mail.smtp.host", host);
props.put("mail.smtp.auth", "true");
// 创建会话对象
Session session = Session.getInstance(props, new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
// 创建邮件对象
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(fromEmail));
message.setRecipient(Message.RecipientType.TO, new InternetAddress(toEmail));
message.setSubject(subject);
message.setText(body);
// 发送邮件
Transport.send(message);
System.out.println("邮件发送成功!");
} catch (MessagingException e) {
e.printStackTrace();
}
}
}
```
请确保将示例代码中的SMTP服务器地址、发件人用户名、发件人密码、发件人邮箱、收件人邮箱等信息替换为您自己的信息。还需要确保您已经添加了JavaMail库到您的项目中。
