Question

这是嵌入在Mule中的RESTful接口，它接受用户名并输出“hello，$ name”

以下是mule-config.xml

中内容的一部分

       <model name="greetingModel">
          <service name="greetingService">
              <inbound>
                  <inbound-endpoint address="http://localhost:9004"/>
              </inbound>
              <outbound>
                  <filtering-router>
                      <outbound-endpoint address="vm://greeting"/>
                      <restlet:uri-template-filter pattern="/hello/{set-payload.name}" verbs="GET"/>
                  </filtering-router>
              </outbound>
          </service>
          <service name="greeting">
              <inbound>
                  <inbound-endpoint address="vm://greeting" exchange-pattern="request-response"></inbound-endpoint>
              </inbound>
              <component class="com.ggd543.mulerestletdemo.GreetingComponent"></component>
          </service>
    </model>

和组件类

package com.ggd543.mulerestletdemo

import org.mule.api.lifecycle.Callable
import org.mule.api.MuleEventContext

class GreetingComponent  extends Callable {

  def onCall(eventContext: MuleEventContext) = {
      val name = eventContext.getMessage.getPayload.asInstanceOf[String]
      sayHello(name)
  }

  def sayHello(name: String) = {
    val msg = "hello, "+name
    println(msg)
    msg
  }
}

成功部署应用后，我尝试在浏览器中访问http://localhost:9004/hello/archer，但没有任何反复发生。

mule-config.xml是否有任何问题？

PS：我的骡子版本是3.1.2而我使用的是mule-transport-restlet-1.1.3.jar

问题是由于VM端点上的交换模式不一致。尝试：

   <model name="greetingModel">
      <service name="greetingService">
          <inbound>
              <inbound-endpoint address="http://localhost:9004"/>
          </inbound>
          <outbound>
              <filtering-router>
                  <outbound-endpoint address="vm://greeting" exchange-pattern="request-response"/>
                  <restlet:uri-template-filter pattern="/hello/{set-payload.name}" verbs="GET"/>
              </filtering-router>
          </outbound>
      </service>
      <service name="greeting">
          <inbound>
              <inbound-endpoint address="vm://greeting" exchange-pattern="request-response"/>
          </inbound>
          <component class="com.ggd543.mulerestletdemo.GreetingComponent" />
      </service>
</model>

Mule Restlet应用程序无法正常工作
