[英]Not able to send mails to gmail account using javamail api
当我尝试将示例邮件发送到gmail帐户时，我收到com.sun.mail.smtp.SMTPAddressFailedException。 以下是我写的代码......有人可以帮我解决这个问题吗？
public class MultiMimes {
public static void main(String[] args) throws Exception{
Properties props = System.getProperties();
props.setProperty("mail.smtp.host", "mailservername");
props.put("mail.debug", "true");
Session session = Session.getDefaultInstance(props,null);
Message message = new MimeMessage(session);
try{
message.setSubject("I am a multipart text/html email" );
Address toAddress =new InternetAddress("my gmail address");
Address fromAddress =new InternetAddress("my organization address");
message.setFrom(fromAddress);
message.addRecipient(Message.RecipientType.TO, toAddress);
MimeMultipart multipart1 = new MimeMultipart("alternative");
// Create text message part
MimeBodyPart textPart = new MimeBodyPart();
textPart.setContent("am text", "text/plain");
textPart.setHeader("MIME-Version" , "1.0" );
textPart.setHeader("Content-Type" , textPart.getContentType() );
System.out.println("textPart.getContentType():"+textPart.getContentType());
// Create html part
MimeBodyPart htmlPart = new MimeBodyPart();
htmlPart.setContent("<html><body><b>am html</b></body></html>", "text/html");
htmlPart.setHeader("MIME-Version" , "1.0" );
htmlPart.setHeader("Content-Type" , "text/html" );
System.out.println("htmlPart.getContentType():"+htmlPart.getContentType());
//adding multiparts to message
multipart1.addBodyPart(htmlPart);
multipart1.addBodyPart(textPart);
message.setContent(multipart1);
//sending message
Transport.send(message);
System.out.println("mail sent successfully");
}catch(AddressException ae){
System.out.println("address exception");
ae.printStackTrace();
}
catch(MessagingException e){
System.out.println("message exception");
e.printStackTrace();
}
}
当我使用来自同一域的电子邮件ID（例如：somebody@test.com）而不是gmail id时，我收到了该电子邮件。
首先，您需要将代码部分更改为：
private static final String SMTP_HOST_NAME = "smtp.gmail.com";
Properties prop = new Properties();
prop.put("mail.smtp.host", SMTP_HOST_NAME);
prop.put("mail.smtp.starttls.enable", "true");
prop.put("mail.smtp.port", "587");
prop.put("mail.smtp.auth", "true");
Authenticator auth = new SMTPAuthenticator();
Session session = Session.getDefaultInstance(prop, auth);
session.setDebug(debug);
这是SMTPAuthenticator类：
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
/**
* SimpleAuthenticator is used to do simple authentication
* when the SMTP server requires it.
*/
public class SMTPAuthenticator extends Authenticator
{
private static final String SMTP_AUTH_USER = "youremail@gmail.com";
private static final String SMTP_AUTH_PASSWORD = "yourpassword";
public PasswordAuthentication getPasswordAuthentication()
{
String username = SMTP_AUTH_USER;
String password = SMTP_AUTH_PASSWORD;
return new PasswordAuthentication(username, password);
}
}
并且请将您的从地址更改为gmail以及解决任何问题，因为您的SMTP身份验证是由gmail完成的，因此该部分必须属于gmail。
希望可能有所帮助。
问候
感谢所有...因为我是satckoverflow的新手...我无法找到确切的方法来添加适当的评论....
在这里，我不是试图通过gmail服务器发送邮件...我只是想发送给一些gmail用户。 使用此代码，我可以向组织内的任何人发送邮件......但不能向组织外的人发送邮件。
任何方式......我通过“Prophesy Awaits”建议找到了我的问题的解决方案......我修改了我的代码如下：
package com.trx;
import java.util.Properties;
import javax.activation.DataHandler;
import javax.activation.DataSource;
import javax.activation.FileDataSource;
import javax.mail.Address;
import javax.mail.Authenticator;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.Session;
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 MultiMimes {
public static void main(String[] args) throws Exception{
Properties props = System.getProperties();
props.setProperty("mail.smtp.host", "mymailserver");
props.put("mail.smtp.port", "25");
props.put("mail.smtp.auth", "true");
props.put("mail.debug", "true");
Authenticator auth = new SMTPAuthenticator();
Session session = Session.getDefaultInstance(props, auth);
Message message = new MimeMessage(session);
try{
message.setSubject("I am a multipart text/html email" );
Address toAddress =new InternetAddress("my gmail address");
Address fromAddress =new InternetAddress("my organization address");
message.setFrom(fromAddress);
message.addRecipient(Message.RecipientType.TO, toAddress);
MimeMultipart multipart1 = new MimeMultipart("alternative");
// Create text message part
MimeBodyPart textPart = new MimeBodyPart();
textPart.setContent("am text", "text/plain");
textPart.setHeader("MIME-Version" , "1.0" );
textPart.setHeader("Content-Type" , textPart.getContentType() );
System.out.println("textPart.getContentType():"+textPart.getContentType());
// Create html part
MimeBodyPart htmlPart = new MimeBodyPart();
htmlPart.setContent("<html><body><b>am html</b></body></html>", "text/html");
htmlPart.setHeader("MIME-Version" , "1.0" );
htmlPart.setHeader("Content-Type" , "text/html" );
System.out.println("htmlPart.getContentType():"+htmlPart.getContentType());
//adding multiparts to message
multipart1.addBodyPart(textPart);
multipart1.addBodyPart(htmlPart);
message.setContent(multipart1);
//sending message
Transport.send(message);
System.out.println("mail sent successfully");
}catch(AddressException ae){
System.out.println("address exception");
ae.printStackTrace();
}
catch(MessagingException e){
System.out.println("message exception");
e.printStackTrace();
}
}
}
我使用了他提供的相同的SMTPAuthenticator类...现在我能够将组织邮件服务器的邮件发送到任何电子邮件ID ...再次感谢。
我认为主机名是一个问题所以将mailservername更改为smtp.gmail.com
