21.6. 发送Email¶
21.6.1. 常用邮件服务商的SMTP信息¶
QQ邮箱：SMTP服务器是smtp.qq.com，端口是465/587；
163邮箱：SMTP服务器是smtp.163.com，端口是465；
Gmail邮箱：SMTP服务器是smtp.gmail.com，端口是465/587。
21.6.2. 发送一封简单的邮件¶
Sendmail01.java
package aom722;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;
public class Sendmail01 {
public static void main(String[] args) throws MessagingException {
String smtp = "smtp.qq.com";
final String username = "1879324764@qq.com";
final String password = "xibeauerdibudaid";
// 连接到SMTP服务器587端口:
Properties props = new Properties();
props.put("mail.smtp.host", smtp); // SMTP主机名
props.put("mail.smtp.port", "587"); // 主机端口号
props.put("mail.smtp.auth", "true"); // 是否需要用户认证
props.put("mail.smtp.starttls.enable", "true"); // 启用TLS加密
// 获取Session实例:
Session session = Session.getInstance(props, new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
// 设置debug模式便于调试:
session.setDebug(true);
MimeMessage message = new MimeMessage(session);
// 设置发送方地址:
message.setFrom(new InternetAddress("1879324764@qq.com"));
// 设置接收方地址:
message.setRecipient(Message.RecipientType.TO, new InternetAddress("962057147@qq.com"));
// 设置邮件主题:
message.setSubject("Hello", "UTF-8");
// 设置邮件正文:
message.setText("你好呀。小健爱吃肉............", "UTF-8");
// 发送:
Transport.send(message);
}
}
21.6.3. 发送HTML邮件¶
发送HTML邮件 发送HTML邮件和文本邮件是类似的，只需要把：
message.setText(body, "UTF-8");
改为：
message.setText(body, "UTF-8", "html");
Sendmail02.java
package aom722;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;
public class Sendmail02 {
public static void main(String[] args) throws MessagingException {
String smtp = "smtp.qq.com";
final String username = "1879324764@qq.com";
final String password = "xibeauerdibudaid";
String info = "<h1>Hello hujianli</h1> <p> nice to me too....</p>";
// 连接到SMTP服务器587端口:
Properties props = new Properties();
props.put("mail.smtp.host", smtp); // SMTP主机名
props.put("mail.smtp.port", "587"); // 主机端口号
props.put("mail.smtp.auth", "true"); // 是否需要用户认证
props.put("mail.smtp.starttls.enable", "true"); // 启用TLS加密
// 获取Session实例:
Session session = Session.getInstance(props, new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
// 设置debug模式便于调试:
session.setDebug(true);
MimeMessage message = new MimeMessage(session);
// 设置发送方地址:
message.setFrom(new InternetAddress("1879324764@qq.com"));
// 设置接收方地址:
message.setRecipient(Message.RecipientType.TO, new InternetAddress("13262662216@163.com"));
// 设置邮件主题:
message.setSubject("Hello", "UTF-8");
// 设置邮件正文:
message.setText(info, "UTF-8", "html");
// 发送:
Transport.send(message);
}
}
