問題與FunctionalTestComponent（騾子3.2.1）

Question

我期望一個<test:component />等同於

<component> 
    <spring-object bean="FTC" /> 
<component> 

在FTC豆使用FunctionalTestComponent類。也就是說，我期望下面的兩個配置通過下面進一步顯示的功能測試。

配置與<test:component />

<mule ...> 
    <vm:endpoint name="EntryPoint.Name" path="EntryPoint.Path" /> 
    <simple-service name="service" endpoint-ref="EntryPoint.Name" > 
     <test:component /> 
    </simple-service> 
</mule> 

配置有彈簧豆使用FunctionalTestComponent

<mule ...> 
    <vm:endpoint name="EntryPoint.Name" path="EntryPoint.Path" /> 
    <spring:bean id="FTC" class="org.mule.tck.functional.FunctionalTestComponent" /> 

    <simple-service name="service" endpoint-ref="EntryPoint.Name" > 
     <component> 
      <spring-object bean="FTC" /> 
     </component> 
    </simple-service> 
</mule> 

測試

@Test 
public void aTest() throws Exception { 
    final MuleClient client = muleContext.getClient(); 
    client.send("vm://EntryPoint.Path", "1", null); 
    assertEquals("1", getFunctionalTestComponent("service").getLastReceivedMessage()); 
} 

<test:component />與該配置通過測試。但是，與FTC豆的那個不一樣。事實上，與FTC豆的運行在日誌中顯示一個例外：

任何想法我可能做錯了什麼？我使用的騾子3.2.1

感謝

我想我想通了。該bean的定義缺少一個屬性init-method= "initialise"。這個細節似乎從documentation丟失。因此，bean的定義應該是：

<spring:bean id="FTC" 
    class="org.mule.tck.functional.FunctionalTestComponent" init-method="initialise" />
