1、引入maven依耐 javax.mail
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4.7</version>
</dependency>
2、邮件配置 , src/main/resources 下面创建配置文件,config/email.properties
#smtp.office365.com 端口587
mail.host=smtp.office365.com
mail.port=587
mail.nick=系统管理员
[email protected]
mail.password=password
[email protected]
[email protected];[email protected]
3、核心代码
package com.demo.email.util;
import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;
import java.util.Properties;
import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
public class SendEmail {
private static String host;
private static String port;
private static String nick;
private static String username;
private static String password;
private static String from;
private static List<String> toList;
static {
init();
}
private static boolean isEmpty() {
if (nick != null && host != null && port != null && username != null && password != null && from != null && toList != null) {
return false;
}
return true;
}
private static void init() {
toList = new ArrayList<String>();
InputStream inStream = SendEmail.class.getResourceAsStream("/config/email.properties");
try {

prop.load(inStream);

String toListStr = prop.getProperty("mail.toList");
String[] split = toListStr.split(";");
for (String string : split) {
toList.add(string);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
if (inStream != null) {
try {
inStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
public static boolean sendEmail(String title,String content) {
if(isEmpty()) {
init() ;
}
Properties properties = System.getProperties();
properties.setProperty("mail.transport.protocol", "smtp");
properties.setProperty("mail.smtp.host", host);
properties.setProperty("mail.smtp.port", port);
properties.setProperty("mail.smtp.auth", "true");
properties.setProperty("mail.smtp.starttls.enable", "true");// outlook邮箱需要加上
Authenticator authenticator = new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
};
Session session = Session.getDefaultInstance(properties, authenticator);
try {
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(nick + " <"+from +">"));
/**

*/
for (String to : toList) {
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
}
message.setSubject(title, "UTF-8");
message.setContent(content, "text/html;charset=UTF-8");
Transport.send(message);
System.out.println("Sent message successfully.... title:"+title);
return true ;
} catch (MessagingException mex) {
mex.printStackTrace();
}
return false;
}
public static void main(String[] args) {
String content = "<a href='http://www.baidu.com'>测试地址</a>" ;
SendEmail.sendEmail("测试内容", content) ;
}
}
