从Camel CXFRS路由响应REST客户端?

我正在尝试在CXFRS Camel路由中创建对REST Web服务调用的响应,但无论我做什么,对客户端的响应总是相同的200,而不是201.这是我的路由:

<route id="front-end">
    <from uri="cxfrs:bean:myService" />
    <setBody>
        <constant>Will do...</constant>
    </setBody>
    <setHeader headerName="CamelHttpResponseCode">
        <constant>201</constant>
    </setHeader>
    <setHeader headerName="Content-Type">
        <constant>more/blah</constant>
    </setHeader>
</route>

返回正文但忽略响应代码​​和内容类型。我做错了什么?

谢谢, 马特

基本上,当将交换转换为实际的HTTP响应时,camel-cxfrs会覆盖在交换中设置的任何标头 见here

exchange.getOut().setHeaders(binding.bindResponseHeadersToCamelHeaders(response, exchange));

这是因为DefaultCxfRsBinding期望jaxrs Response作为参数。

因此,要解决此问题,请使用自定义方法覆盖DefaultCxfRsBinding,以便从exchange.getIn()复制标头。

    <cxf:rsServer id="MyService" address="/myAddress">      
    <cxf:binding><bean class="MyCustomCxfRsBinding" /></cxf:binding>                
    <cxf:serviceBeans>
        <ref bean="myResourceWithJSR311Annotations" />
    </cxf:serviceBeans>
    </cxf:rsServer>

或者让你的camel路由返回jaxrs响应带标题,而不是在路由器或camel处理器中设置标头。什么

class HttpHeaderProcessor implements Processor
{
    @Override
    public void process(Exchange exchange) throws Exception
    {
        Message message = exchange.getIn();
        Response response = convertToJaxRs(message);
        exchange.getIn().setBody(response);
        exchange.getIn().setHeader("Test", "Won't work unless DefaultCxfRsBinding is not replaced with a custom one");

    }

    private Response convertToJaxRs(Message message)
    {
        ResponseBuilder jaxrsResponseBuilder = Response.ok(message.getBody(), MediaType.APPLICATION_XML);
        jaxrsResponseBuilder.header("header1", "you'll see this");
        Response response = jaxrsResponseBuilder.build();
        return response;
    }
}

您的样本:

<route id="front-end">
    <from uri="cxfrs:bean:myService" />
    <setBody>
        set it to Response.ok(your message).header(x, y).build()
    </setBody>

您还可以使用Service bean返回带有标题的jaxrs.Response

<route id="front-end">
    <from uri="cxfrs:bean:myService" />
    <bean ref="myServiceImpl">
