程序入口：

Test_Email_N.java

importjava.io.IOException;importjava.util.Date;importjava.util.Properties;importjavax.mail.Authenticator;importjavax.mail.BodyPart;importjavax.mail.Message;importjavax.mail.MessagingException;importjavax.mail.Multipart;importjavax.mail.Transport;importjavax.mail.internet.AddressException;importjavax.mail.internet.InternetAddress;importjavax.mail.internet.MimeBodyPart;importjavax.mail.internet.MimeMessage;importjavax.mail.internet.MimeMultipart;public classTest_Email_N {public static voidmain(String args[]){try{

send_email();

}catch(Exception e) {

e.printStackTrace();

}

}public static void send_email() throwsIOException, AddressException, MessagingException{

String to= "1215186706@qq";

String subject= "subject";

String content= "content";

Properties properties= newProperties();

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

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

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

Authenticator authenticator= new Email_Authenticator("1215186706@qq", "password");

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

MimeMessage mailMessage= newMimeMessage(sendMailSession);

mailMessage.setFrom(new InternetAddress("1215186706@qq"));//Message.RecipientType.TO属性表示接收者的类型为TO

mailMessage.setRecipient(Message.RecipientType.TO, newInternetAddress(to));

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

mailMessage.setSentDate(newDate());//MiniMultipart类是一个容器类，包含MimeBodyPart类型的对象

Multipart mainPart = newMimeMultipart();//创建一个包含HTML内容的MimeBodyPart

BodyPart html = newMimeBodyPart();

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/projects/javamail/pages/Home直接下载jar包.

javax.mail

mail

1.5.0-b01

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

packagecom.infomorrow.webtest.JuxinliTest.restdetect;importjavax.mail.Authenticator;importjavax.mail.PasswordAuthentication;public class Email_Authenticator extendsAuthenticator {

String userName= null;

String password= null;publicEmail_Authenticator() {

}publicEmail_Authenticator(String username, String password) {this.userName =username;this.password =password;

}protectedPasswordAuthentication getPasswordAuthentication() {return newPasswordAuthentication(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:

如下图，新建一个email.propertis文件。

email.propertis:

mail.smtp.host=smtp.qq

mail.smtp.port=25username=1215186706@qq

password=password

Test_Email.java 代码改为如下：

packagecom.infomorrow.webtest.JuxinliTest.restdetect;importjava.io.IOException;importjava.io.InputStream;importjava.util.Date;importjava.util.Properties;importjavax.mail.Authenticator;importjavax.mail.BodyPart;importjavax.mail.Message;importjavax.mail.MessagingException;importjavax.mail.Multipart;importjavax.mail.Transport;importjavax.mail.internet.AddressException;importjavax.mail.internet.InternetAddress;importjavax.mail.internet.MimeBodyPart;importjavax.mail.internet.MimeMessage;importjavax.mail.internet.MimeMultipart;public classTest_Email {

public static void main(String args[]){

try{

send_email();

}catch(Exception e) {

e.printStackTrace();

}

}public static void send_email() throwsIOException, AddressException, MessagingException{

String to= "1215186706@qq";

String subject= "subject";//邮件主题

String content= "content";//邮件内容

Properties properties= newProperties();

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= newMimeMessage(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, newInternetAddress(to));

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

mailMessage.setSentDate(newDate());//MiniMultipart类是一个容器类，包含MimeBodyPart类型的对象

Multipart mainPart = newMimeMultipart();//创建一个包含HTML内容的MimeBodyPart

BodyPart html = newMimeBodyPart();

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

mainPart.addBodyPart(html);

mailMessage.setContent(mainPart);

Transport.send(mailMessage);

}

}

ok,到此为止。
