Question

我们试图使用JMS模板发送MAP（java.util），但是在客户端，我们无法读取该消息，并且在服务器启动过程中，spring boot @JMSListener会显示以下消息，这可以正常工作在WAS 7中，但在WAS Liberty 8.5.5中没有，iam还包括代码段以及我们为不同版本的服务器接收的不同消息格式。 WAS Liberty有什么变化吗？

曾经是自由主义者-7-

#include <stdlib.h>

void *bsearch(const void *key, const void *base,
              size_t nmemb, size_t size,
              int (*compar)(const void *, const void *))
{
    const unsigned char *p;
    size_t m;
    int r;

    while (nmemb > 0) {
        m = (nmemb - 1) >> 1;
        p = (const unsigned char *)base + m * size;
        if ((r = compar(key, p)) < 0) {
            nmemb = m;
        } else
        if (r > 0) {
            base = p + size;
            nmemb -= m + 1;
        } else
        if (m == 0) {
            return (void *)p;
        } else {
            /* continue search to return first matching entry */
            nmemb = m + 1;
        }
    }
    // if you want the insertion point, you can return p here
    return NULL;
}

消息是MAP

WAS-自由消息格式

 jmsTemplate.convertAndSend(destination, message, new MessagePostProcessor() {
                    @Override
                    public Message postProcessMessage(Message message) throws JMSException {
                        message.setJMSReplyTo(null);
                        LOGGER.info("In BaseBowUpdateSender - send() message to AMPS-BASE QUEUE : {} ", message);
                        return message;
                    }
                });

Answer 1

我的应用程序（JMS应用程序）将WebSphere MQ消息放入队列。这些消息将由jms应用程序接收。我误解了targetClientId选项，以为如果我们编写的消息是MQ则需要将targetClientId提到为“ mq”，但事实并非如此。仅当我们使用非以下方式处理消息时，才需要将targetClientId设置为MQ： jms应用程序。当我将targetClientId设置为'MQ'时，它剥离了JMS应用程序处理消息所需的RFH标头，并且在使用该应用程序时解析失败。

        <jmsQueue id="MYAPP_QUEUE" jndiName="jms/test/testq">
            <properties.wmqJms 
                baseQueueName="MYAPP.TEST.A" 
                persistence="PERS" 
                targetClient="MQ"/> -- removed this 
        </jmsQueue>

从WAS Liberty读取消息并将消息写入MQ
