骆驼cxfrs RESTful客户端/ProducerTemplate ConnectionTimeout [英] Camel cxfrs RESTful client / ProducerTemplate ConnectionTimeout

问题描述

我正在尝试为Camel CXF-RS组件设置'connectionTimeout'此处在第三方服务上产生一个RESTful请求.默认的30000毫秒为long.

I am trying to set the 'connectionTimeout' for a Camel CXF-RS component here which produces a RESTful requests on a 3rd party service. The default 30000 miliseconds is to long.

Exchange exchange = template.send("cxfrs://" + url, new Processor() {
 public void process(Exchange exchange) throws Exception {
  exchange.setPattern(ExchangePattern.InOut);
  Message inMessage = exchange.getIn();
  setupDestinationURL(inMessage);
  // using the http central client API
  inMessage.setHeader(CxfConstants.CAMEL_CXF_RS_USING_HTTP_API, Boolean.TRUE);
  // set the Http method
  inMessage.setHeader(Exchange.HTTP_METHOD, "PUT");
  // set the relative path
  inMessage.setHeader(Exchange.HTTP_PATH, url);                
  // Specify the response class , cxfrs will use InputStream as the response                 object type 
  inMessage.setHeader(CxfConstants.CAMEL_CXF_RS_RESPONSE_CLASS, Customer.class);
  // set a customer header
  inMessage.setHeader("key", "value");
  // since we use the Get method, so we don't need to set the message body
  inMessage.setBody(null);                
 }
});

我已经尝试像许多建议一样将其添加到我们的application-context中，但是在通过HTTPConduit和HTTPClientPolicy类进行调试时看不到它修改了默认值:

I have tried adding this to our application-context as many have suggested, but cannot see it modifying the default values when debugging through the HTTPConduit and HTTPClientPolicy classes:

<http-conf:conduit name="*.http-conduit">
  <http-conf:client ConnectionTimeout="5000"/>
</http-conf:conduit>

并且我尝试添加

 "?httpClientAPI=true&connectionTimeout=5000" 

作为网址字符串的选项.

as options to the url string.

任何帮助或指导将不胜感激.

Any help or guidance would be much appreciated.

推荐答案

像往常一样在application-context中添加http-conf:conduit元素是可行的方法.是什么让您说不呢?

Adding the http-conf:conduit element in application-context as you did is the way to go and should work. What makes you say it does not?

通常，后端服务器在建立连接后 花费的时间太长.在这种情况下，设置ReceiveTimeout与ConnectionTimeout同样重要.

Quite often a backend server take too long to answer, after the connection is made; in this case setting ReceiveTimeout is as important as ConnectionTimeout.

这是一个骆驼路线示例，它使用RS请求并调用第三方RS服务器. ReceiveTimeout和ConnectionTimeout参数按预期工作.

This is a sample camel Route which consumes RS requests and calls a third-party RS server; the ReceiveTimeout and ConnectionTimeout parameters work as expected.

<cxf:rsServer id="rsFrontServer" address="..." serviceClass="..."/>

<cxf:rsClient id="rsBackendClient" address=".../" serviceClass="..."/>

<http-conf:conduit name="*.http-conduit">
    <http-conf:client ReceiveTimeout="5000" ConnectionTimeout="5000"/>
</http-conf:conduit>

<camelContext xmlns="http://camel.apache.org/schema/spring">
    <route id="front">
        <from uri="cxfrs:bean:rsFrontServer"/>
        <!-- do stuff -->
        <to uri="cxfrs:bean:rsBackendClient"/>
    </route>
</camelContext>
