Java 使用Spring框架的空邮件

java spring maven email

Java 使用Spring框架的空邮件,java,spring,maven,email,Java,Spring,Maven,Email,我试图使用Spring框架发送一封简单的电子邮件，但我有一个非常奇怪的问题：在Junit测试用例中，一切都正常工作，但是当我从应用程序调用该函数时，邮件有正确的收件人，但它是空的！（在Gmail中我可以看到一个“没有名字”的附件）以下是我的配置： MailerServiceImpl @Override public void sendMail(String recipient, String content, String attachmentFileName, byte[]

我试图使用Spring框架发送一封简单的电子邮件，但我有一个非常奇怪的问题：在Junit测试用例中，一切都正常工作，但是当我从应用程序调用该函数时，邮件有正确的收件人，但它是空的！（在Gmail中我可以看到一个“没有名字”的附件）

以下是我的配置：

MailerServiceImpl

@Override
public void sendMail(String recipient, String content,
        String attachmentFileName, byte[] attachment) throws Exception {

    MimeMessage message = mailSender.createMimeMessage();


    MimeMessageHelper helper = new MimeMessageHelper(message, true);
    helper.setFrom(simpleMailMessage.getFrom());
    helper.setTo(recipient);
    helper.setSubject(simpleMailMessage.getSubject());
    helper.setText(String.format(simpleMailMessage.getText(), content));

    if (attachment != null && attachmentFileName != null) {
        helper.addAttachment(attachmentFileName, new ByteArrayResource(
                attachment));
    }
    logger.log(Level.INFO, "MimeMessageHelper Created");
    try {
        mailSender.send(message);
        logger.log(Level.INFO, "Email sent to: "
                + message.getAllRecipients().toString());
    } catch (MailException e) {
        logger.log(Level.SEVERE, "Error while sending mail", e);
        throw new EipException("Errore email", e);
    }

}

    this.mailSender = mailSender;
}

}

在Junit测试用例中，我加载了相同的spring上下文，webapp中唯一的区别是数据库配置（通过Tomcat中的JNDI）。。。但这不应该成为问题

我想到了Maven中的库冲突（我读到了与geronimo邮件的冲突）。。。但似乎效果不错有什么建议吗

再见卡洛

编辑：这是两封已发送电子邮件的两个日志。（前者是空白的，后者是正确的）
