Question

我尝试访问的网站仅发送xml。使用Camel的XML DSL，我试图获取该XML并通过cxrfs将其发送到另一个站点。就目前而言，我可以满足于转向bean，只能访问数据。

当我执行我的路线时，我不一定会遇到任何错误。它只是没有对XML做任何事情，可能是因为它没有存储在正文中。但不确定。

输出

路线

<bean id="proc" class="com.b2bservicep1.httpserv.Proc"/>

<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
    <route>
        <from uri="timer://foo?repeatCount=1"/>
       <setHeader headerName="CamelHttpMethod">

我写的处理器

package com.b2bservicep1.httpserv;

import javax.ws.rs.GET;

import org.apache.camel.Exchange;
import org.apache.camel.Processor;

public class Proc implements Processor{

    @Override @GET
    public void process(Exchange arg0) throws Exception {
        // TODO Auto-generated method stub
        System.out.println("My Processor! Get In");
        System.out.println(arg0.getIn().getBody());
        System.out.println("My Processor! Get out");
        System.out.println(arg0.getOut());
    }

您需要指定的不仅仅是一个Method标头。这是一个例子

@Test
public void testGetCustomerWithCxfRsEndpoint() {
    Exchange exchange 
        = template.send("cxfrs://http://localhost:" + getPort1() + "/" + getClass().getSimpleName() + "/?httpClientAPI=true", new Processor() {
            public void process(Exchange exchange) throws Exception {
                exchange.setPattern(ExchangePattern.InOut);
                Message inMessage = exchange.getIn();
                // set the Http method
                inMessage.setHeader(Exchange.HTTP_METHOD, "GET");
                // set the relative path
                inMessage.setHeader(Exchange.HTTP_PATH, "/customerservice/customers/123");                
                // Specify the response class , cxfrs will use InputStream as the response object type 
                inMessage.setHeader(CxfConstants.CAMEL_CXF_RS_RESPONSE_CLASS, Customer.class);
                // since we use the Get method, so we don't need to set the message body
                inMessage.setBody(null);                
            }
        });

    // get the response message 
    Customer response = (Customer) exchange.getOut().getBody();
    assertNotNull("The response should not be null ", response);
    assertEquals("Get a wrong customer id ", String.valueOf(response.getId()), "123");
    assertEquals("Get a wrong customer name", response.getName(), "John");
    assertEquals("Get a wrong response code", 200, exchange.getOut().getHeader(Exchange.HTTP_RESPONSE_CODE));
}
