如何通过安慰JMS发送确定的消息

Question

我有一个非常简单的生产者类型程序，它试图将ByteMessage发送到一个主题。

我的程序收到错误com.solacesystems.jms.ConfigurationException: Error sending message - operation not supported on router (Cannot send assured message: Assured message delivery is not enabled on this channel.)

如何确保发送的邮件不是有保证的邮件？这是一些安慰配置变量吗？这是我试图使用的简单的JMS相关代码bytes是我要发送的对象：

val connection = connectionFactory.createConnection()
val session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE)
val publishDestination = session.createTopic(solace.TOPIC)
val message = new SolBytesMessage()
message.writeBytes(bytes)
val producer = session.createProducer(publishDestination)
producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT)
log.info("Sending message")
producer.send(publishDestination, message)

Answer 1

这可以通过强制QOS来解决：

    JmsTemplate jmsTemplate = new JmsTemplate(cachingConnectionFactory);
    jmsTemplate.setDefaultDestinationName(topic);
    jmsTemplate.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
    jmsTemplate.setExplicitQosEnabled(true);

请确认在设备的连接出厂设置中选中了int main() { char a[]="ATCG"; char *dna[20]; // <-- this was char dna[20] char *dna1; dna1 = (char *)malloc(2000); int i, len_of_seg_2; for(i = 0; i < strlen(a); i++) { len_of_seg_2=strlen(a)-i+1; strncpy(dna1, a+i, len_of_seg_2); dna1[len_of_seg_2-1]='\0'; dna[i]=dna1; // <-- this was the crash printf("sequence:%s\n",dna1); } for(i=0;i<5;i++){ printf("\nseq:%s\n",dna[i]); } return 0; } 。

连接工厂中的Direct Transport设置控制用于非持久性消息的传输。
