问题与FunctionalTestComponent（骡子3.2.1）

Question

我期望一个<test:component />等同于

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

在FTC豆使用FunctionalTestComponent类。也就是说，我期望下面的两个配置通过下面进一步显示的功能测试。

配置与<test:component />

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

配置有弹簧豆使用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> 

测试

@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 />与该配置通过测试。但是，与FTC豆的那个不一样。事实上，与FTC豆的运行在日志中显示一个例外：

    + 3 more (set debug level logging or '-Dmule.verbose.exceptions=true' for everything)

任何想法我可能做错了什么？我使用的骡子3.2.1

感谢

我想我想通了。该bean的定义缺少一个属性init-method= "initialise"。这个细节似乎从documentation丢失。因此，bean的定义应该是：

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