Mule模块发布订阅读取xsd路径失败

Question

我正在尝试实现mule发布-订阅模块。我得到了以下错误：

cvc-complex-type.2.4.a: Invalid content was found starting with element 'pubsub:config'. One of '{"http://www.mulesoft.org/schema/mule/core":annotations, "http://www.mulesoft.org/schema/mule/core":description, "http://www.springframework.org/schema/beans":beans, "http://www.springframework.org/schema/beans":bean, "http://www.springframework.org/schema/context":property-placeholder, "http://www.springframework.org/schema/beans":ref, "http://www.mulesoft.org/schema/mule/core":global-property, "http://www.mulesoft.org/schema/mule/core":configuration, "http://www.mulesoft.org/schema/mule/core":notifications, "http://www.mulesoft.org/schema/mule/core":abstract-extension, "http://www.mulesoft.org/schema/mule/core":abstract-mixed-content-extension, "http://www.mulesoft.org/schema/mule/core":abstract-agent, "http://www.mulesoft.org/schema/mule/core":abstract-security-manager, "http://www.mulesoft.org/schema/mule/core":abstract-transaction-manager, "http://www.mulesoft.org/schema/mule/core":abstract-connector, "http://www.mulesoft.org/schema/mule/core":abstract-global-endpoint, "http://www.mulesoft.org/schema/mule/core":abstract-exception-strategy, "http://www.mulesoft.org/schema/mule/core":abstract-flow-construct, "http://www.mulesoft.org/schema/mule/core":flow, "http://www.mulesoft.org/schema/mule/core":sub-flow, "http://www.mulesoft.org/schema/mule/core":abstract-model, "http://www.mulesoft.org/schema/mule/core":abstract-interceptor-stack, "http://www.mulesoft.org/schema/mule/core":abstract-filter, "http://www.mulesoft.org/schema/mule/core":abstract-transformer, "http://www.mulesoft.org/schema/mule/core":processor-chain, "http://www.mulesoft.org/schema/mule/core":custom-processor, "http://www.mulesoft.org/schema/mule/core":invoke, "http://www.mulesoft.org/schema/mule/core":abstract-global-intercepting-message-processor, "http://www.mulesoft.org/schema/mule/core":custom-queue-store, "http://www.mulesoft.org/schema/mule/core":abstract-processing-strategy}' is expected.

看起来，它在抱怨元素

我的代码：

    <?xml version="1.0" encoding="UTF-8"?>
    <mule xmlns="http://www.mulesoft.org/schema/mule/core"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:spring="http://www.springframework.org/schema/beans"
    xmlns:vm="http://www.mulesoft.org/schema/mule/vm"
    xmlns:pubsub="http://www.mulesoft.org/schema/mule/pubsub"
    xsi:schemaLocation="

    <flow name="testListenerTopicA">
    <pubsub:listener config-ref="my-config" topic="topic-A"/>
    <logger level="INFO" message="Received an event for topic A with payload #[payload]"/>
    </flow>
    <flow name="testListenerTopicB">
    <logger level="INFO" message="Received an event for topic B with payload #[payload]"/>
    </flow>
    <flow name="testPublisherTopicA">
    <pubsub:publish config-ref="my-config" topic="topic-A"/>
    </flow>
    <flow name="testPublisherTopicB">
    <pubsub:publish config-ref="my-config" topic="topic-B"/>
    </flow>
    <flow name="testSubscribeTopicB">
    <pubsub:subscribe config-ref="my-config" topic="topic-B" subscriberId="123" flow-ref="testListenerTopicB"/>
    </flow>
    <flow name="testUnsubscribeTopicB">
    <pubsub:unsubscribe config-ref="my-config" topic="topic-B" subscriberId="123"/>
    </flow>
    </mule>

如有任何帮助，我将不胜感激。

可能您没有将该模块添加到项目中。它没有被添加到构建中，然后Mule找不到元素的定义。
