Java发送带html标签内容的邮件实例代码
如下所示:
package test;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeUtility;
import javax.mail.Session;
import javax.mail.MessagingException;
import javax.mail.Transport;
public class SendHtmlMail {
public static void sendMessage(String smtpHost, String from, String to,String subject, String messageText) throws MessagingException,
java.io.UnsupportedEncodingException {
// Step 1: Configure the mail session
System.out.println("Configuring mail session for: " + smtpHost);
java.util.Properties props = new java.util.Properties();
props.setProperty("mail.smtp.auth", "true");// 指定是否需要SMTP验证
props.setProperty("mail.smtp.host", smtpHost);// 指定SMTP服务器
props.put("mail.transport.protocol", "smtp");
Session mailSession = Session.getDefaultInstance(props);
mailSession.setDebug(false);// 是否在控制台显示debug信息
// Step 2: Construct the message
System.out.println("Constructing message - from=" + from + " to=" + to);
InternetAddress fromAddress = new InternetAddress(from);
InterkGitNiOJKnetAddress toAddress = new InternetAddress(to);
MimeMessage testMessage = new MimeMessage(mailSession);
testMessage.setFrom(fromAddress);
testMessage.addRecipient(javax.mail.Message.RecipientType.TO, toAddress);
testMessage.setSentDate(new java.util.Date());
testMessage.setSubject(MimeUtility.encodeText(subject, "gb2312", "B"));
testMessage.setContent(messageText, "text/html;charset=gb2312");
System.out.println("Message constructed");
// Step 3: Now send the message
Transport transport = mailSession.getTransport("smtp");
transport.connect(smtpHost, "riteng_mes", "ri-teng1234");
transport.sendMessage(testMessage, testMessage.getAllRecipients());
transport.close();
System.out.println("Message sent!");
}
public static void main(String[] args) {
String smtpHost = "10.131.119.36";
String from = "Riteng_Mes@casetekcorp.com";
String to = "Qiang1_Zhang@intra.casetekcorp.com";
String subject = "html邮件测试"; // subject javamail自动转码
StringBuffer theMessage = new StringBuffer();
theMessage.append("
theMessage.append("
theMessage.append("年年失望年年望");
theMessage.append("
try {
SendHtmlMail.sendMessage(smtpHost, from, to, subject,theMessage.toString());
} catch (javax.mail.MessagingException exc) {
exc.printStackTrace();
} catch (java.io.UnsupportedEncodingException exc) {
exc.printStackTrace();
}
}
}
