通过Java发送邮件时出现异常

Question

Getting exception while sending mail through Java

exception is::

Exception in thread "main" java.lang.NoSuchMethodError: 
com.sun.mail.util.LineOutputStream.<init>(Ljava/io/OutputStream;Z)V
at javax.mail.internet.MimeBodyPart.writeTo(MimeBodyPart.java:1648)
at javax.mail.internet.MimeMessage.writeTo(MimeMessage.java:1906)
at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:1134)

at javax.mail.Transport.send(Transport.java:124)
at com.yodlee.SendMail.sendMail(SendMail.java:78)

Here is the Java code::

    Properties props = new Properties();
    props.put(SMTP_HOST_KEY,SMTP_HOST);

    Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(".....",
                    "#.......");
        }
    });

    try {
        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress(RECIPIENT_FROM));
        message.setSubject(SUBJECT);
        message.setSentDate(new Date());
        //message.setText("Test mails111");


        MimeBodyPart messageBodyPart = new MimeBodyPart();

        messageBodyPart.setContent(data, "text/html");
        Multipart multipart = new MimeMultipart();
        multipart.addBodyPart(messageBodyPart);
        message.setContent(multipart);
        Transport.send(message);
        System.out.println("Done");
    } catch (MessagingException e) {
        status = -1;
        throw new RuntimeException(e);
    }

I am getting error at Transport.send(msg); Jars i am using here:: smtp 1.6.0, Javax Mail 1.4.7 , mailactivation

Answer 1

Most likely you have multiple versions of the JavaMail classes on your class path. Check all your dependencies and your application server environment for conflicts. If more than one jar file contains the javax.mail.* or com.sun.mail.* classes, you have a problem.

And be sure to fix all these common JavaMail mistakes , and definitely be sure to use the latest version of JavaMail .

Answer 2

检查你的jar的版本，尝试更改一些版本，如果它是'maven项目'，请检查环境依赖项。如您所知，java的环境通常会出现错误，您可能要小心。

Answer 3

I fix the issue: java.lang.NoSuchMethodError: 'void com.sun.mail.util.LineOutputStream.(java.io.OutputStream, boolean)'

Added in my pom.xml the dependencies com.sun.mail with same version of the javax.mail-api

<dependency>
        <groupId>javax.mail</groupId>
        <artifactId>javax.mail-api</artifactId>
        <version>1.6.2</version>
    </dependency>

    <dependency>
        <groupId>com.sun.mail</groupId>
        <artifactId>javax.mail</artifactId>
        <version>1.6.2</version>
    </dependency>
