Apache Camel - 如何在 java 中使用属性配置端点

Question

这是我在XML中完美工作的骆驼路线

<route id="someId">
<from id="_from" uri="{{consumer.serviceName}}:queue:{{consumer.notificationQueue}}?{{consumer.queryParams}}"/>
<log loggerRef="loggerId" message="Messages throttling from Queue"/>
<throttle prop:timePeriodMillis="{{throttle.timePeriod}}">
<constant>{{throttle.maximumRequestsPerSecond}}</constant>
<log loggerRef="logger" message="Consuming notification message from Queue {{consumer.myQueue}} : ${body}"/> 
<bean id="beanId" method="process" ref="MyProcessor"/>
</throttle>
</route>

现在，我想用 Java 编写一个类似的 Camel 端点。 你能告诉我如何在其中添加日志和限制属性吗？

MyProcessor  messageProcessor;
String Uri = serviceName + ":queue:" + queueName + "?" + queryParams;
Endpoint ep = camelContext.getEndpoint(Uri);
Consumer consumer = ep.createConsumer(messageProcessor);
consumer.start();

我希望它能帮助你：

from("{{consumer.serviceName}}:queue:{{consumer.notificationQueue}}?{{consumer.queryParams}}").id("from_")
.log(LoggingLevel.INFO, loggerObject, "Messages throttling from Queue")
.throttle(constant("{{maximumRequestsPerSecond}}")).timePeriodMillis(1000)//pass throttle.timePeriod parameter from your config here
.log(LoggingLevel.INFO, loggerObject, "Consuming notification message from Queue {{consumer.myQueue}} : ${body}")
.bean(beanObject, "process").id("beanId")
.end();
