方式一：
依赖的jar包：mail.jar
代码：
import java.util.Date;
import java.util.Properties;
import javax.mail.Address;
import javax.mail.Authenticator;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.Multipart;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
public class MyTest {
public boolean sendMail(boolean textOrHtml) {
try {
Properties props = new Properties();
Authenticator auth = new MyAutherticator("邮箱帐号","密码");//邮件服务器认证
props.put("mail.smtp.host", "smtp.sina.com.cn");
props.put("mail.smtp.auth", "true");
Session session = Session.getDefaultInstance(props,auth);
//设置session,和邮件服务器进行通信
MimeMessage message = new MimeMessage(session);
message.setSubject("邮件的主题");
message.setSentDate(new Date());//设置邮件发送日期
Address address = new InternetAddress("帐号","我的邮件");
message.setFrom(address);//设置邮件发送者的地址
Address toaddress = new InternetAddress("收件人邮箱");//设置邮件接收者的地址
message.addRecipient(Message.RecipientType.TO,toaddress);
if(textOrHtml)message.setText("邮件内容mail's content....."); //内容为文本
else {//内容为html
Multipart mainPart = new MimeMultipart();
BodyPart html = new MimeBodyPart();
//发送的内容还有超链接，或者直接一个网址 收件箱怎么都收不到，为什么？！被当作垃圾邮件过滤了？！
String myHtmlContent ="<font color=red>你好</font>" ;
//+"http://www.guihua.org";
// +"<a href=\"http://www.baidu.com\">链接</a>";
html.setContent(myHtmlContent, "text/html; charset=utf-8");
mainPart.addBodyPart(html); // 将MiniMultipart对象设置为邮件内容
message.setContent(mainPart);
}
Transport.send(message);//发送邮件
return true;
} catch (Exception e) {
e.printStackTrace();
}
return false;
}
public static void main(String[] args) {
MyTest a = new MyTest();
if(a.sendMail(true))System.out.println("send text mail successfully!!");
if(a.sendMail(false))System.out.println("send html mail successfully!!");
}
}
MyAutherticator类的代码：
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
public class MyAutherticator extends Authenticator {
String username = "";
String password = "";
public Email_Autherticator() {
super();
}
public Email_Autherticator(String user,String pwd){
super();
this.username = user;
this.password = pwd;
}
public PasswordAuthentication getPasswordAuthentication(){
return new PasswordAuthentication(username,password);
}
}

方式二：
依赖的jar包：mail.jar spring.jar commons-logging.jar
代码如下：
import java.io.File;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeUtility;
import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;
public class SendFileMail3 {
public static boolean sendMailWithFiles() {
try {
JavaMailSenderImpl senderImpl = new JavaMailSenderImpl();
// 设置邮件服务器
senderImpl.setHost("smtp.sina.com.cn");
senderImpl.setUsername("帐号");
senderImpl.setPassword("密码");
MimeMessage mailMessage = senderImpl.createMimeMessage();
// true表示开始附件模式
MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage, true, "utf-8");
// 设置收件人，寄件人
messageHelper.setTo("收件人邮箱");
messageHelper.setFrom("帐号");
messageHelper.setSubject("测试邮件！");
// true 表示启动HTML格式的邮件
messageHelper.setText("<html><head></head><body><h1>你好：附件！！" +
"</h1><a href=\"http://www.baidu.com\">邮件测试内容</a></body></html>", true);
//这儿就能加超链接了
FileSystemResource file1 = new FileSystemResource(new File("文件地址"));
FileSystemResource file2 = new FileSystemResource(new File("文件二地址"));
// 添加两个附件
messageHelper.addAttachment("文件", file1);
//防止中文文件名出现乱码
messageHelper.addAttachment(MimeUtility.encodeWord("中文名"), file2);
senderImpl.send(mailMessage);
return true;
} catch (Exception e) {
e.printStackTrace();
}
return false;
}
public static void main(String[] args) {
if(sendMailWithFiles())System.out.println("邮件发送成功.....");
}
}

注意：使用方案一，无法发送带有链接地址的邮件。邮件可以发送成功，但是无法收到。
PS:使用新浪的smtp这样，腾讯的可以正常收到，
如果有链接地址，建议使用方案二。
