【问题描述】：
在我的 Camel Router.java 中，我有下一条路线
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");
上述骆驼路线出现问题。如果我通过使用bin/kafka-console-producer.sh --topic testing --bootstrap-server localhost:9092 运行的Kafka 生产者向主题testing 发送一些消息，则从Kafka 到JMS 的路由工作正常。所以这些链接的骆驼路线有些问题。
在 Camel pom.xml 中有 Spring Boot camel-kafka-starter 和 camel-jms-starter 依赖项。
当我使用 Maven 启动 Spring Boot Camel 并将一些消息从 Kafka 生产者发送到 Kafka 代理 testing 主题时，我可以看到 Kafka 代理收到了该消息，并且上面的日志打印正常。
.to("jms:topic:test.sink.topic"); 行出现错误，我不知道是什么意思。

当从 JMS 向 Kafka 发送一些消息时，路由工作正常。
【问题讨论】：
-
我已经用完整的错误记录、骆驼路线和有关问题的更多信息更新了问题。使用 -e 和 -X 运行 maven 并没有提供有关错误的更多详细信息。
-
我根据堆栈跟踪更新了我的答案。
