1. Specify the text encoding when sending the text :

Use

MimeBodyPart body = new MimeBodyPart(); body.setContent(content, "text/html;charset=GB2312");

Copy after login

when sending emails. Note that the content encoding at this time must be the specified encoding format.

2. When setting the email title, you must also specify the encoding of the title:

MimeMultipart mmp=new MimeMultipart(); mmp.setSubject(subject, "GB2312");

Copy after login

The same as above also requires that the encoding of the subject is consistent with the specified encoding.

3. You can also specify the transfer encoding in the header when sending the text:

body.setHeader("Content-Transfer-Encoding", "base64"); // 指定使用base64编码

Copy after login

4. Example:

import java.util.Properties; import javax.mail.*; import javax.mail.internet.*; public class MailSender { public static void main(String[] args) { try { String host = "staff.tixa.com"; // smtp主机 String username = "sample@staff.tixa.com"; // 认证用户名 String password = "sample"; // 认证密码 String from = "例子"; // 发送者 String to = "toOne@staff.tixa.com, toAnother@staff.tixa.com"; // 接受者，用“,”分隔 String subject = "测试例子"; String content = "仅仅是个供测试的例子。"; // 建立session Properties prop = new Properties(); prop.put("mail.smtp.host", host); prop.put("mail.smtp.auth", "true"); //是否需要认证 Session session = Session.getDefaultInstance(prop, null); // 创建MIME邮件对象 MimeMessage mimeMsg = new MimeMessage(session); MimeMultipart mp = new MimeMultipart(); // 设置信息 mimeMsg.setFrom(new InternetAddress(from)); mimeMsg.setSubject(subject, "GB2312"); // ！！！注意设置编码 mimeMsg.setRecipients( Message.RecipientType.TO, InternetAddress.parse(to)); // 设置正文 BodyPart body = new MimeBodyPart(); body.setContent(content, "text/plain;charset=GB2312"); // ！！！注意设置编码 mp.addBodyPart(body); mimeMsg.setContent(mp); // 发送邮件 Transport transport = session.getTransport("smtp"); transport.connect(host, username, password); transport.sendMessage(mimeMsg,mimeMsg.getRecipients(Message.RecipientType.TO)); transport.close(); } catch(Exception exp) { exp.printStackTrace(); } }
