java - Spring jms activemq

Question

我使用activemq和spring jms。我有一个问题。

这是我的电子邮件发送器

@Service
@PropertySource("classpath:/properties/dev/application.properties")
public class EmailSenderImpl implements EmailSender {
    private static final Logger LOGGER = LoggerFactory.getLogger(EmailSenderImpl.class);

    @Autowired
    private JmsTemplate jmsTemplate;

    @Autowired
    private Environment env;

    @Override
    public void sendEmail(final Users user, EmailCauses emailCause) {
        LOGGER.debug("Sending email to user with id {} with cause {}", user.getId(), emailCause);

        //Retrieve User profile which defined with lazy fetch type.
        //It prevents org.hibernate.LazyInitializationException in jms message receiver method
        user.getUserProfile();

        jmsTemplate.send(env.getProperty(emailCause.getEmailQueueName()),
                new MessageCreator () {

                    @Override
                    public Message createMessage(Session session) throws JMSException {
                        return session.createObjectMessage(user);
                    }
                }
        );  
    } 

这是我的电子邮件处理程序。

@Service
public class EmailHandler {
    private static final Logger LOGGER = LoggerFactory.getLogger(EmailHandler.class);

    private JavaMailSender mailSender;
    private VelocityEngine velocityEngine;
    private MessageSource messageSource;


    @Autowired
    public EmailHandler (JavaMailSender mailSender, VelocityEngine velocityEngine, MessageSource messageSource) {

        this.mailSender = mailSender;
        this.velocityEngine = velocityEngine;
        this.messageSource = messageSource;
    }


    //TODO - refactor method, add reserve server
    @Transactional
    public void processEmailNotifications (Users user) throws MessagingException, UnsupportedEncodingException {
        LOGGER.debug("Preparing to send greeting email to user {}", user);

        UserProfiles userProfile = user.getUserProfile();

        Map <String, Object> model = new HashMap <> ();
        model.put("name", userProfile.getName());
        model.put("patronymic", userProfile.getPatronymic());
        model.put("token", UriUtils.encode(user.getConfirmationToken(), "UTF8"));

        String email = user.getUserProfile().getEmail();
        sendEmail(email, "email.wellcome.subject", model, "wellcome_email.vm");

    }
     private void sendEmail (String emailTo, String subjectMessage, Map<String, Object> model, String templateName) {
        LOGGER.debug("Sending email to {} with subject message {}", emailTo, subjectMessage);

        try {

            MimeMessage message = mailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper (message, true, "UTF-8");

            helper.setTo(emailTo);
            helper.setSubject(messageSource.getMessage(subjectMessage, null, Locale.getDefault()));

            String emailText = VelocityEngineUtils.mergeTemplateIntoString(velocityEngine, templateName, "UTF-8", model);
            helper.setText(emailText, true);

            mailSender.send(message);
            LOGGER.info("Email to address {} with subject {} was sent successfully", emailTo, subjectMessage);

        } catch (MessagingException me) {
            LOGGER.error("Email to address {} was not sent", emailTo, me);

        }

    }

我的堆栈跟踪中有以下日志。我不明白为什么它不起作用。

o.s.jms.core.JmsTemplate - Executing callback on JMS Session: ActiveMQSession {id=ID:igor-Aspire-5820TG-33061-1474030841626-1:7:1,started=false} 2016-09-16 16:02:40.871 - [http-bio-8080-exec-6] [DEBUG] o.s.jms.core.JmsTemplate - Sending created message: ActiveMQTextMessage {commandId = 0, responseRequired = false, messageId = null, originalDestination = null, originalTransactionId = null, producerId = null, destination = null, transactionId = null, expiration = 0, timestamp = 0, arrival = 0, brokerInTime = 0, brokerOutTime = 0, correlationId = null, replyTo = null, persistent = false, type = null, priority = 0, groupID = null, groupSequence = 0, targetConsumerId = null, compressed = false, userID = null, content = null, marshalledProperties = null, dataStructure = null, redeliveryCounter = 0, size = 0, properties = null, readOnlyProperties = false, readOnlyBody = false, droppable = false, text = xDDD}

您能否发布其他日志和 JmsTemplate 设置配置，因为 session 未在您的日志上启动，并且生产者、messageid 和目的地...信息为空
