我正在使用Apache Commons电子邮件向我的客户发送电子邮件,但我有一个名为'SemanadaComputação'的客户(在portugues BR中),但它是'SemanadaComputação'.我尝试修改我的代码,但它没有任何工作:
public static boolean emailWithImage(String subject, String message, String emailReceiver, String imageURL) {
HtmlEmail email = new HtmlEmail();
email.setCharset("UTF-8"); // I change here, but it is not working
email.setHostName(Constantes.EMAIL_HOST_NAME);
email.setSmtpPort(587);
DefaultAuthenticator authenticator =
new DefaultAuthenticator(Constantes.EMAIL_USER, Constantes.EMAIL_PASSWORD);
email.setAuthenticator(authenticator);
email.setTLS(true);
try {
email.setFrom(Constantes.EMAIL_USER, Constantes.EMAIL_NAME);
email.setSubject(subject);
email.addTo(emailReceiver);
URL url = new URL(imageURL);
String cid = email.embed(url, "image"); /* it must be 'cid' the name of the image */
email.setHtmlMsg("<html><img src=\"cid:" + cid + "\"> <p>" + message + "</p> </html>"); /* …我正在使用Apache Commons电子邮件库发送电子邮件,但我无法通过GMail SMTP服务器发送它们.
任何人都可以提供与GMail SMTP服务器和其他服务器兼容的示例代码吗？
我使用以下代码不起作用:
String[] recipients = {"receiver@gmail.com"};
SimpleEmail email = new SimpleEmail();
email.setHostName("smtp.gmail.com");
email.setAuthentication("sender@gmail.com", "mypasswd");
email.setDebug(true);
email.setSmtpPort(465);
for (int i = 0; i < recipients.length; i++)
{
email.addTo(recipients[i]);
}
email.setFrom("sender@gmail.com", "Me");
email.setSubject("Test message");
email.setMsg("This is a simple test of commons-email");
email.send();
当我将 Spring Boot 应用程序更新到 Java 17 和 Spring Boot 3 时，我从 Java EE 迁移到 Jakarta。我使用了 MimeMessageParser org.apache.commons.mail.util.MimeMessageParser，但它需要javax.mail.internet.MimeMessagea 而不是jakarta.mail.internet.MimeMessage。
org.apache.commons我认为artifact可能有更新commons-email，但我已经使用当前版本（1.5）。
有人找到了如何替换 MimeMessageParser 的解决方案吗？
如何将使用Apache Commons Email生成的电子邮件的编码更改为UTF-8？我想根据收件人的语言发送我生成的电子邮件,我需要考虑日语和俄语.问题是:Email类没有提出我可以传递给该Email.setCharset方法的UTF-8常量.任何线索？
我正在使用Apache Commons Email 1.1,我无法弄清楚如何将文件附加到HtmlEmail.如果我运行下面的代码,我会收到一封带附件的电子邮件,但HTML邮件也会作为附件出现.
如果我不调用email.attach(),HTML消息就会如您所愿,但我需要HTML消息和附件.我错过了什么？
HtmlEmail email = new HtmlEmail();
email.setHostName("localhost");
email.addTo("test@mail.com", "Test");
email.setFrom("testapp@mail.com", "Test App");
email.setSubject("Test message");
email.setHtmlMsg("<div style='font-size: 20px; color: green;'>This is html email</div>");
EmailAttachment attachment = new EmailAttachment();
attachment.setPath(pdfPath);
attachment.setDisposition(EmailAttachment.ATTACHMENT);
email.attach(attachment);
email.send();
我想向不同的收件人发送数千封不同的电子邮件,并希望打开与我的SMTP的连接并保留它.我希望这更快,然后重新打开ervy邮件的连接.我想使用Apache Commons Email,但如果有必要,可以回退到Java Mail API.
现在我正在这样做,每次打开关闭连接:
HtmlEmail email = new HtmlEmail();
email.setHostName(server.getHostName());
email.setSmtpPort(server.getPort());
email.setAuthenticator(new DefaultAuthenticator(server.getUsername(), server.getPassword()));
email.setTLS(true);
email.setFrom("test@example.com");
email.addTo(to);
email.setSubject(subject);
email.setHtmlMsg(htmlMsg);
email.send();
Email email = new SimpleEmail();
String authuser = "......@gmail.com";
String authpwd = "*******";
// Very Important, Don't use email.setAuthentication()
email.setSmtpPort(465);
email.setAuthenticator(new DefaultAuthenticator(authuser, authpwd));
email.setDebug(true); // true if you want to debug
email.setHostName("smtp.gmail.com");
email.getMailSession().getProperties().put("mail.smtp.auth", "true");
email.getMailSession().getProperties().put("mail.debug", "true");
email.getMailSession().getProperties().put("mail.smtp.port", "465");
email.getMailSession().getProperties().put("mail.smtp.socketFactory.port", "465");
email.getMailSession().getProperties().put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
email.getMailSession().getProperties().put("mail.smtp.socketFactory.fallback", "false");
email.getMailSession().getProperties().put("mail.smtp.starttls.enable", "true");
email.setFrom("........@gmail.com", "SenderName");
email.setSubject("TestMail");
email.setMsg("This is a test mail?");
email.addTo(".............@gmail.com", "ToName");
email.send();
它给出了以下例外
SEVERE: org.apache.commons.mail.EmailException: Sending the email to the following server failed : smtp.gmail.com:465
目前我使用Commons Email发送电子邮件,但我找不到在发送的电子邮件之间共享smtp连接的方法.我有以下代码:
Email email = new SimpleEmail();
email.setFrom("example@example.com");
email.addTo("example@example.com");
email.setSubject("Hello Example");
email.setMsg("Hello Example");
email.setSmtpPort(25);
email.setHostName("localhost");
email.send();
这是非常易读的,但是当我执行大量消息时速度很慢,我认为这是重新连接每条消息的开销.因此,我使用以下代码对其进行了分析,并发现使用重新使用Transport会使事情快三倍.
Properties props = new Properties();
props.setProperty("mail.transport.protocol", "smtp");
Session mailSession = Session.getDefaultInstance(props, null);
Transport transport = mailSession.getTransport("smtp");
transport.connect("localhost", 25, null, null);
MimeMessage message = new MimeMessage(mailSession);
message.setFrom(new InternetAddress("example@example.com"));
message.addRecipient(Message.RecipientType.TO, new InternetAddress("example@example.com"));
message.setSubject("Hello Example");
message.setContent("Hello Example", "text/html; charset=ISO-8859-1");
transport.sendMessage(message, message.getAllRecipients());
所以我想知道是否有办法让Commons Email重用多个电子邮件发送的SMTP连接？我更喜欢Commons Email API,但性能有点痛苦.
谢谢,赎金
我在我的网络应用程序中使用Apache Commons Email,它工作正常.
现在我需要通过附件发送文档,我遇到了一些问题.我需要从数据库中获取文件(作为BLOB)并将其添加为附件.看起来Commons Email不支持流附件,它只从路径中获取文件.
我需要知道这里的最佳做法是什么？
我正在尝试发送一个base64编码的文件apache.commons.mail,我只是不能接缝以获得Content-Transfer-Encoding: base64它应该去的标题.
// Create the email
MultiPartEmail email = new MultiPartEmail();
email.setSmtpPort(587);
email.setDebug(false);
email.setHostName("smtp.gmail.com");
email.setAuthentication("from@gmail.com", "password");
email.setTLS(true);
email.addTo("to@example.com");
email.setFrom("from@example.com");
email.setSubject("subject");
email.attach(new ByteArrayDataSource(
Base64.encodeBase64(attachFull.getBytes()), "text/plain"),
"samplefile.txt",
"sample file desc",
EmailAttachment.ATTACHMENT
);
而这正是收件人所获得的.
------=_Part_0_614021571.1334210788719
Content-Type: text/plain; charset=Cp1252; name=texto.txt
Content-Transfer-Encoding: quoted-printable
Content-Disposition: attachment; filename=samplefile.txt
Content-Description: sample file desc
我如何指定该文件是Base64编码？
在发送电子邮件时,我使用commons-email-1.3收到以下错误.
我已经下载并添加了外部jar到项目中.
请帮我解决这个问题!
package mypkg;
import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.Email;
import org.apache.commons.mail.SimpleEmail;
public class sendingmail {
public static void main(String[] args) throws Exception {
Email email = new SimpleEmail();
email.setSmtpPort(587);
email.setAuthenticator(new DefaultAuthenticator("myid","mypwd")); //Here is the error
email.setDebug(false);
email.setHostName("smtp.gmail.com");
email.setFrom("me@gmail.com");
email.setSubject("Hi");
email.setMsg("This is a test mail ... :-)");
email.addTo("you@gmail.com");
email.setTLS(true);
email.send();
System.out.println("Mail sent!");
}
}
给出错误的行是
email.setAuthenticator(new DefaultAuthenticator("myid","mypwd"));
错误消息是
线程"main"中的异常java.lang.Error:未解决的编译问题:
无法解析javax.mail.Authenticator类型.它是从所需的.class文件间接引用的.来自
类型Email的方法setAuthenticator(Authenticator)是指mypkg.mailtest.main中缺少的类型Authenticator(mailtest.java:13)
试着玩!发送带附件的电子邮件的框架.如果我不在邮件中添加附件,则以下代码可以正常工作.我已经尝试过使用Play的Mailer类和Apache Commons类(如下所示),但在这两种情况下,页面都只使用微调器(Chrome)并且没有收到任何电子邮件.
EmailAttachment attachment = new EmailAttachment();
attachment.setURL(new URL(base + "public/images/triangles.png"));
attachment.setDisposition(EmailAttachment.ATTACHMENT);
attachment.setDescription("test");
attachment.setName("test");
emailaddress = "test@test.com";
MultiPartEmail email = new MultiPartEmail();
email.setDebug(true);
email.addTo(emailaddress);
email.setFrom("Testing <test@test.com>");
email.setSubject("Testing email");
try
{
email.attach(attachment);
}
catch (EmailException ex)
{
System.out.println(ex.getMessage());
}
email.setMsg("test email");
email.send();
我正在尝试通过GMail发送电子邮件(实际上是Google Apps).这适用于普通消息,但当然我必须测试极端情况.
现在我正在尝试发送没有正文的消息,我收到一条奇怪的错误消息.因为我想消除代码中的错误,我想知道我做错了什么,或者我正在使用的库中是否有错误.
HtmlEmail currentMessage = new HtmlEmail();
currentMessage.setSSL(true);
currentMessage.setSslSmtpPort(465);
currentMessage.setHostName("smtp.gmail.com");
currentMessage.setAuthentication("abc@gmail.com", "secret");
/** rs is a ResultSet from database **/
if(rs.getString("mailFrom") != null && !rs.getString("mailFrom").isEmpty())
currentMessage.setFrom(rs.getString("mailFrom"));
else
currentMessage.setFrom("abc@gmail.com");
currentMessage.setTo(this.convertRecipientStringToArray(rs.getString("mailTo")));
currentMessage.setCc(this.convertRecipientStringToArray(rs.getString("mailCC")));
currentMessage.setBcc(this.convertRecipientStringToArray(rs.getString("mailBC")));
currentMessage.setSubject(rs.getString("mailSubject"));
if(rs.getString("mailBody") != null && !rs.getString("mailBody").isEmpty())
currentMessage.setTextMsg(rs.getString("mailBody"));
if(rs.getString("mailHtmlBody") != null && !rs.getString("mailHtmlBody").isEmpty())
currentMessage.setHtmlMsg(rs.getString("mailHtmlBody"));
if(rs.getString("mailReplyTo") != null && !rs.getString("mailReplyTo").isEmpty())
currentMessage.addReplyTo(rs.getString("mailReplyTo"));
else
currentMessage.addReplyTo("def@gmail.com");
currentMessage.send();
此代码适用于"普通"电子邮件:具有有效的正文,主题,收件人等.
当数据库中的mailBody 和 mailHtmlBody都为NULL或为空时,我收到以下错误:
将电子邮件发送到以下服务器失败:smtp.gmail.com:25
