Question

我希望<test:component />等同于

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

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

配置<test:component />

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

使用FunctionalTestComponent配置Spring bean

<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 />的配置通过了测试。但是，使用FTC bean的那个没有。实际上，使用FTC bean的运行在日志中显示异常：

知道我可能做错了吗？我正在使用Mule 3.2.1

由于

Answer 1

我想我明白了。 bean的定义缺少一个属性init-method= "initialise"。 documentation似乎缺少这个细节。因此，bean的定义应该是：

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