Question

我有一个groovy脚本生成一个RSS源，我试图使用文件端点写入$ {app.home} / rss。

然后我通过http端点将此RSS提要作为静态资源提供。

<flow name="rssModifier" doc:name="rssModifier">
    <quartz:inbound-endpoint jobName="job" repeatInterval="300000" responseTimeout="10000" doc:name="Quartz">
        <quartz:event-generator-job/>
    </quartz:inbound-endpoint>
    <all doc:name="All">
        <processor-chain>
            <scripting:component doc:name="FirstGroovyRssFeed">
                <scripting:script engine="Groovy" file="C:\git-gms\edus-esb-rss-test-harness\src\main\java\edu\ucdavis\iet\edus\rsstestharness\server\groovy\InitializeRssFeed.groovy"/>
            </scripting:component>
            <logger message="#[payload]" level="INFO" doc:name="Logger"/>
            <file:outbound-endpoint path="${app.home}/rss/groovy.xml" responseTimeout="10000" doc:name="File"/>
        </processor-chain>

    </all>
</flow>

<flow name="httpWebServer" doc:name="httpWebServer">
    <http:inbound-endpoint address="http://localhost:8084/static" doc:name="HTTP" exchange-pattern="request-response" connector-ref="HTTP_HTTPS"/>
    <http:static-resource-handler resourceBase="${app.home}/rss" 
           defaultFile="rometest.xml" doc:name="HTTP Static Resource Handler"/>
    <logger message="#[payload] #[message]" level="INFO" doc:name="Logger"/>
</flow>

我确认运行此应用程序时，$ {app.home}目录中存在groovy.xml文件，但是我收到以下错误，并且rss feed xml没有被写入文件：

我弄清楚我做错了什么。我只需要定义文件出站端点的目录路径。我还需要一个文件连接器，定义如下：

<file:connector name="output" autoDelete="false" outputAppend="true" outputPattern="groovy.xml" streaming="false" validateConnections="true" doc:name="File"/>

文件连接器配置为允许附加到现有文件（如果存在），并通过＆quot; outputPattern＆＃39;来定义文件的名称。属性。

使用Mule工作流和文件端点写入$ {app.home}
