Java 如何停止骆驼http重试

我们正在使用camel 2.18.1的toD组件向http web服务发布正文，但当url无效时，camel会在内部重试2-3分钟，这是我不希望看到的

我进一步研究发现，camel在内部使用

org.apache.commons.httpclient.HttpMethodDirector

执行重试操作。如何才能阻止骆驼这样做

零件异常日志如下所示

实现HttpClientConfigurer并将其发送到注册表

@Bean(name = "httpConfigurer")
public HttpClientConfigurer createCustomConfigurer() {
    return new HttpClientConfigurer() {

        @Override
        public void configureHttpClient(HttpClient client) {
            client.getParams().setParameter(HttpConnectionParams.CONNECTION_TIMEOUT, 10000);
            client.getParams().setParameter("http.method.retry-handler", new DefaultHttpMethodRetryHandler(0, false));            }
    };
}

设置HttpComponent的

httpClientConfigurer

，如下所示：

.toD("http://1.2.3.4/xyz?httpClientConfigurer=httpConfigurer")

每当我们使用无效URL并试图发布消息时，线程都会等待2分钟以上，直到超时。因此，其他线程会被卡住。那么，我可以将camel route builder的连接超时配置为10秒吗？您在这里提到的示例是使用“to”组件，但我们使用的是routebuilder中的“toD”（使用java DSL）。添加

client.getParams（）.setParameter（HttpConnectionParams.connection\u TIMEOUT，10000）

到

配置HttpClient

，正如您在我的更新答案中所看到的。您是否尝试过用类似

OneException（ConnectException.class）.handled（true）.maximumRedeliveries（0）？在这里，你明确地说，不应尝试重新交付。@RomanVottner我面临着同样的问题。我尝试了这个解决方案，但它没有从
maximumRedeliveries
方法中选择重试次数，也没有覆盖它。在我看来，它似乎是由
org.apache.commons.httpclient.HttpMethodDirector
类驱动的
@Bean(name = "httpConfigurer")
public HttpClientConfigurer createCustomConfigurer() {
    return new HttpClientConfigurer() {

        @Override
        public void configureHttpClient(HttpClient client) {
            client.getParams().setParameter(HttpConnectionParams.CONNECTION_TIMEOUT, 10000);
            client.getParams().setParameter("http.method.retry-handler", new DefaultHttpMethodRetryHandler(0, false));            }
    };
}

.toD("http://1.2.3.4/xyz?httpClientConfigurer=httpConfigurer")
