Java 使用apachecamel管理超时

我有以下路线定义：

@Override
public void configure() throws Exception {
    from(String.format("direct:%s", this.connector))
    .id("Route1")
    .threads()
    .maxPoolSize(10)
    .keepAliveTime(3000)
    .timeUnit(TimeUnit.MICROSECONDS)
    .poolSize(1)
    .rejectedPolicy(ThreadPoolRejectedPolicy.Abort)
    .log("Calling WS")
    .maxQueueSize(1)
    .to("http://10.8.4.9:8080/service");
}

以及上面的请求：

InputStream exchange = (InputStream) template
            .requestBodyAndHeaders(url, AppUtil.parse(this.body, input), this.headers);

端点故意不可用。所以，我希望我的请求等待3秒钟，并抛出一些异常作为响应。相反，会发生以下行为：

骆驼重试3次，不考虑超时

我尝试使用：

onException(ConnectException.class)
.maximumRedeliveries(0);

没有成功

我错过了什么

keepAliveTime（3000）不是用于HTTP端点的，它是Java中JVM线程池的API。您可以在Java API for thread Pool中阅读关于此选项的内容，在Camel DSL中也有一些关于该方法的javadoc

如果需要HTTP连接超时等，则需要在HTTP端点上设置特定选项
