程序入口:

Test_Email_N.java

复制代码 代码如下:

import java.io.IOException;

import java.util.Date;

import java.util.Properties;

import javax.mail.Authenticator;

import javax.mail.BodyPart;

import javax.mail.Message;

import javax.mail.MessagingException;

import javax.mail.Multipart;

import javax.mail.Transport;

import javax.mail.internet.AddressException;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeBodyPart;

import javax.mail.internet.MimeMessage;

import javax.mail.internet.MimeMultipart;

public class Test_Email_N {

public static void main(String args[]){

try {

send_email();

}catch (Exception e) {

e.printStackTrace();

}

}

public static void send_email() throws IOException, AddressException, MessagingException{

String to = "1219999@qq.com";

String subject = "subject";

String content = "content";

Properties properties = new Properties();

properties.put("mail.smtp.host", "smtp.qq.com");

properties.put("mail.smtp.port", "25");

properties.put("mail.smtp.auth", "true");

Authenticator authenticator = new Email_Authenticator("1219999@qq.com", "password");

javax.mail.Session sendMailSession = javax.mail.Session.getDefaultInstance(properties, authenticator);

MimeMessage mailMessage = new MimeMessage(sendMailSession);

mailMessage.setFrom(new InternetAddress("1219999@qq.com"));

// Message.RecipientType.TO属性表示接收者的类型为TO

mailMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(to));

mailMessage.setSubject(subject, "UTF-8");

mailMessage.setSentDate(new Date());

// MiniMultipart类是一个容器类,包含MimeBodyPart类型的对象

Multipart mainPart = new MimeMultipart();

// 创建一个包含HTML内容的MimeBodyPart

BodyPart html = new MimeBodyPart();

html.setContent(content.trim(), "text/html; charset=utf-8");

mainPart.addBodyPart(html);

mailMessage.setContent(mainPart);

Transport.send(mailMessage);

}

}

其中依赖的jar包为javax.mail,我这里是maven管理的,直接用maven去下载jar包,也可以到https://java.net/projects/javamail/pages/Home直接下载jar包.

复制代码 代码如下:

<dependency>

<groupId>javax.mail</groupId>

<artifactId>mail</artifactId>

<version>1.5.0-b01</version>

</dependency>

Email_Authenticator.java,这里继承了Authenticator 类,用来封装name,和password的:

复制代码 代码如下:

package com.infomorrow.webtest.JuxinliTest.restdetect;

import javax.mail.Authenticator;

import javax.mail.PasswordAuthentication;

public class Email_Authenticator extends Authenticator {

String userName = null;

String password = null;

public Email_Authenticator() {

}

public Email_Authenticator(String username, String password) {

this.userName = username;

this.password = password;

}

protected PasswordAuthentication getPasswordAuthentication() {

return new PasswordAuthentication(userName, password);

}

}

配置就这么多,把邮箱密码改成自己的就可以了,否则会报错。程序到这就可以运行了!

下面介绍的是配置properties文件来管理账号密码:

新建一个email.propertis文件。

email.propertis:

复制代码 代码如下:

mail.smtp.host=smtp.qq.com

mail.smtp.port=25

username=1219999@qq.com

password=password

Test_Email.java 代码改为如下:

复制代码 代码如下:

package com.infomorrow.webtest.JuxinliTest.restdetect;

import java.io.IOException;

import java.io.InputStream;

import java.util.Date;

import java.util.Properties;

import javax.mail.Authenticator;

import javax.mail.BodyPart;

import javax.mail.Message;

import javax.mail.MessagingException;

import javax.mail.Multipart;

import javax.mail.Transport;

import javax.mail.internet.AddressException;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeBodyPart;

import javax.mail.internet.MimeMessage;

import javax.mail.internet.MimeMultipart;

public class Test_Email {

public static void main(String args[]){

try {

send_email();

}catch (Exception e) {

e.printStackTrace();

}

}

public static void send_email() throws IOException, AddressException, MessagingException{

String to = "1215186706@qq.com";

String subject = "subject";//邮件主题

String content = "content";//邮件内容

Properties properties = new Properties();

InputStream resourceAsStream = null;

try {

resourceAsStream = Object.class.getResourceAsStream("/email.properties");

properties.load(resourceAsStream);

} finally{

if (resourceAsStream!=null) {

resourceAsStream.close();

}

}

System.err.println("properties:"+properties);

properties.put("mail.smtp.host", properties.get("mail.smtp.host"));

properties.put("mail.smtp.port", properties.get("mail.smtp.port"));

properties.put("mail.smtp.auth", "true");

Authenticator authenticator = new Email_Authenticator(properties.get("username").toString(), properties.get("password").toString());

javax.mail.Session sendMailSession = javax.mail.Session.getDefaultInstance(properties, authenticator);

MimeMessage mailMessage = new MimeMessage(sendMailSession);

mailMessage.setFrom(new InternetAddress(properties.get("username").toString()));

// Message.RecipientType.TO属性表示接收者的类型为TO

mailMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(to));

mailMessage.setSubject(subject, "UTF-8");

mailMessage.setSentDate(new Date());

// MiniMultipart类是一个容器类,包含MimeBodyPart类型的对象

Multipart mainPart = new MimeMultipart();

// 创建一个包含HTML内容的MimeBodyPart

BodyPart html = new MimeBodyPart();

html.setContent(content.trim(), "text/html; charset=utf-8");

mainPart.addBodyPart(html);

mailMessage.setContent(mainPart);

Transport.send(mailMessage);

}

}

ok,到此为止。
