我有一个用模板编写Java的简单电子邮件程序，用于格式化发送电子邮件的数据，这些数据应该以格式显示。但是，它只是显示数据以及嵌入其中的标签，而不实际解析它们。SpringVelocityhtmlhtml

我在这里错过了什么吗？

电子邮件服务.java

public class EmailService {
    private static final Log LOG = LogFactory.getLog(EmailService.class);
    private static final String EMAIL_SUBJECT = ":: Risk Assessment Job Summary Results::";
    private final MailSender mailSender;
    private final String emailRecipientAddress;
    private final String emailSenderAddress;
    private static final String ERROR_MSG = "Error while sending notification email";
    private final TemplateFactory velocityTemplateFactory;
    private Template riskAssessmentJobResultSummaryTemplate;

    public EmailService(MailSender mailSender, String emailRecipientAddress,
            String emailSenderAddress, TemplateFactory velocityTemplateFactory) {
        this.mailSender = mailSender;
        this.emailRecipientAddress = emailRecipientAddress;
        this.emailSenderAddress = emailSenderAddress;
        this.velocityTemplateFactory = velocityTemplateFactory;
    }

    public void notify(String messageBody) {
        JavaMailSender javaMailSender = (JavaMailSender)mailSender;
        MimeMessage message = javaMailSender.createMimeMessage();
        MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(message);
        try {
            mimeMessageHelper.setSubject(getHostname() + " - " + EMAIL_SUBJECT);
            mimeMessageHelper.setTo(emailRecipientAddress);
            mimeMessageHelper.setFrom(emailSenderAddress);
            mimeMessageHelper.setText(getEmailContent(messageBody));
            javaMailSender.send(message);
        } catch (MailException e) {
            throw new EmailSendException(ERROR_MSG, e);
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }

    private static String getHostname() {
        try {
            return InetAddress.getLocalHost().getHostName();
        } catch (UnknownHostException e) {
            return "unknown host";
        }
    }

    private String getEmailContent(String messageBody) {
        try {
            StringWriter stringWriter = new StringWriter();
            this.riskAssessmentJobResultSummaryTemplate =
                    velocityTemplateFactory.create("velocity/risk-assessment-job-results-summary.vm");
            VelocityContext velocityContext = new VelocityContext();
            velocityContext.put("hostname", getHostname());
            velocityContext.put("messageBody", messageBody);
            this.riskAssessmentJobResultSummaryTemplate.merge(velocityContext, stringWriter);
            return stringWriter.toString();
        } catch (IOException ex) {
            LOG.error("Unable to read the email template", ex);
            return null;
        }
    }
}

风险评估作业结果summary.vm

<h3>Summary report for Risk Assessment Job on ${hostname}:</h3>
<table style="border:none;">
    <tr><td>${messageBody}</td></tr>
</table>

实际电子邮件输出：

<h3>Summary report for Risk Assessment Job on KOP-DBT0J12:</h3> 
<table style="border:none;">
<tr><td>
TotalTxPending: 0
TotalTxAccepted: 0
TotalTxRejected: 0
TotalTxProcessed: 0
</td></tr>
</table>

预期的电子邮件输出：

Summary report for Risk Assessment Job on KOP-DBT0J12:
TotalTxPending: 0
TotalTxAccepted: 0
TotalTxRejected: 0
TotalTxProcessed: 0

将内容设置为html

 message.setContent(getEmailContent(messageBody), "text/html; charset=utf-8")

找到了确凿的证据:)

这一行更改解决了问题。这里的true标志表示内容类型html在电子邮件正文中。

mimeMessageHelper.setText(getEmailContent(messageBody), true);

这应该是答案

mimeMessageHelper.setContent(someHtmlMessage, "text/html; charset=utf-8");
