从Kafka到JMS的骆驼路线不工作（JMS->Kafka->JMS）

Question

from("jms:topic:test.source.topic?asyncConsumer=true")
            .log("Message: ${body}")
            .to("kafka:testing?brokers=192.168.0.100:9092");

from("kafka:testing?brokers=192.168.0.100:9092")
            .log("Message received from Kafka : ${body}")
            .log("    on the topic ${headers[kafka.TOPIC]}")
            .log("    on the partition ${headers[kafka.PARTITION]}")
            .log("    with the offset ${headers[kafka.OFFSET]}")
            .log("    with the key ${headers[kafka.KEY]}")
            // manually set JMSDeliveryMode (1 - NON_PERSISTENT, 2 - PERSISTENT)
            .process(new Processor() {
                @Override
                public void process(Exchange exchange) throws Exception {
                    exchange.getIn().setHeader("JMSDeliveryMode", "1");
               }
            })
            .to("jms:topic:test.sink.topic");

当从JMS向Kafka发送消息时，路由运行良好。

Answer 1

以下是相关的错误消息：

AMQ139015: Illegal deliveryMode value: 0

此错误消息表示有东西调用了JMS方法javax.JMS.message#setJMSDeliveryMode，其值为0。0的值无效。有效的交付模式值由javax.jms.DeliveryMode定义：

• 1（对于非持久性）
• 2（用于持久化）。
