1、首先准备：进入自己邮箱，设置--》pop3/smtp(开启它如果已经开启则不用管)

2、准备java的jar包mail.jar

3、代码实现：

package p1;  
import java.io.UnsupportedEncodingException;  
import java.util.Date;  
import java.util.Properties;  
import javax.mail.MessagingException;  
import javax.mail.Session;  
import javax.mail.Transport;  
import javax.mail.internet.InternetAddress;  
import javax.mail.internet.MimeMessage;  
  
  
public class SendEmail \{  
//发件人邮箱密码  
public static String myEmailCount="zhangyunfeixyz@126.com";  
public static String myEmailPwd="z\*\*\*\*\*\*\*";  
//邮箱的smtp  
public static String myEmailSMTP="smtp.163.com";  
//收件人邮箱  
public static String recevieEmail="920869693@qq.com";//我的另一个邮箱  
public static void main(String\[\] args)  
throws MessagingException, UnsupportedEncodingException \{  
//创建参数用于连接邮件服务器  
Properties props = new Properties();  
//使用smtp协议  
props.setProperty("mail.transport.protocol", "smtp");  
//发件人邮箱  
props.setProperty("mail.smtp.host", myEmailSMTP);  
props.setProperty("mail.smtp.auth", "true");//认证、、  
/\*//SMTP 服务器的端口 ,非 SSL 连接的端口一般默认为 25一下内容一般可不写  
\* 具体的端口查看自己邮箱，或问客服，或上网查查  
final String smtpPort = "25";  
        props.setProperty("mail.smtp.port", smtpPort);  
        props.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");  
        props.setProperty("mail.smtp.socketFactory.fallback", "false");  
        props.setProperty("mail.smtp.socketFactory.port", smtpPort); \*/  
//创建会话对象  
Session session=Session.getDefaultInstance(props);  
session.setDebug(true);  
//创建邮件  
MimeMessage message=createMail(session,myEmailCount,recevieEmail);  
   //获取邮件传输对象  
Transport transport = session.getTransport();  
transport.connect(myEmailCount, myEmailPwd);  
//发件  
transport.sendMessage(message, message.getAllRecipients());  
//关闭连接  
transport.close();  
\}  
public static MimeMessage createMail(Session session,String myEmail,String reEmail)   
throws UnsupportedEncodingException, MessagingException\{  
   //创建邮件  
MimeMessage message = new MimeMessage(session);  
//发件人  
message.setFrom(new InternetAddress(myEmail,  
"张三","utf-8"));  
//收件人  
message.setRecipient(MimeMessage.RecipientType.TO, new InternetAddress(reEmail));  
//抄送  
message.setRecipient(MimeMessage.RecipientType.CC, new InternetAddress(myEmail));  
//主题  
message.setSubject("今早好么","utf-8");  
//正文，支持HTML  
message.setContent("今早好么","text/html;charset=utf-8");  
//时间  
message.setSentDate(new Date());  
//保存前面的设置  
message.saveChanges();  
return message;  
\}  
\}
