java中发邮件代码 java实现发送邮件功能( 二 )

IT技术设置


throw new IOException("验证失败！");
}
}
// 开始发送消息，邮件源地址
public void mailfrom(String source, BufferedReader in, BufferedWriter out)
throws IOException {
int result;
result = sendServer("MAIL FROM:" + source + "", in, out);
if (result != 250) {
throw new IOException("指定源地址错误");
}
}
// 设置邮件收件人
public void rcpt(String touchman, BufferedReader in, BufferedWriter out)
throws IOException {
int result;
result = sendServer("RCPT TO:" + touchman + "", in, out);
if (result != 250) {
throw new IOException("指定目的地址错误！");
}
}
// 邮件体
public void data(String from, String to, String subject, String content,
BufferedReader in, BufferedWriter out) throws IOException {
int result;
result = sendServer("DATA", in, out);
// 输入DATA回车后,若收到354应答后,继续输入邮件内容
if (result != 354) {
throw new IOException("不能发送数据");
}
out.write("From: " + from);
out.newLine();
out.write("To: " + to);
out.newLine();
out.write("Subject: " + subject);
out.newLine();
out.newLine();
out.write(content);
out.newLine();
// 句号加回车结束邮件内容输入
result = sendServer(".", in, out);
//System.out.println(result);
if (result != 250) {
throw new IOException("发送数据错误");
}
}
// 退出
public void quit(BufferedReader in, BufferedWriter out) throws IOException {
int result;
result = sendServer("QUIT", in, out);
if (result != 221) {
throw new IOException("未能正确退出");
}
}
// 发送邮件主程序
public boolean sendMail(MailMessage message, String server) {
try {
BufferedReader in = new BufferedReader(new InputStreamReader(
socket.getInputStream()));
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(
socket.getOutputStream()));
helo(server, in, out);// HELO命令
authLogin(message, in, out);// AUTH LOGIN命令
mailfrom(message.getFrom(), in, out);// MAIL FROM
rcpt(message.getTo(), in, out);// RCPT
data(message.getDatafrom(), message.getDatato(),
message.getSubject(), message.getContent(), in, out);// DATA
quit(in, out);// QUIT
} catch (Exception e) {
e.printStackTrace();
return false;
}
return true;
}
}
再写一个MailMessage.java，set/get方法即可 。
如何在 java 发邮件中提供链接？代码如下java中发邮件代码：
import java.util.Properties;
import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.Message.RecipientType;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
public class EmailTest {
public static void main(String[] args) throws Exception{
Properties props = new Properties();
props.setProperty("mail.smtp.auth", "true");
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", "smtp.163.com");
Session session = Session.getInstance(props,
new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication(){
return new PasswordAuthentication("xxx","xxx");//这里分别填写发送emailjava中发邮件代码的用户名、密码
}
}
);
session.setDebug(true);
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress("xxx"));//这里是发送方java中发邮件代码的email地址如java中发邮件代码：xxx@163.com
msg.setSubject("test javamail");
msg.setRecipients(RecipientType.TO,
