我使用mule处理来自sftp的文件,但我需要按顺序处理文件(序列按文件名顺序)。
例如:
sftp中有3个文件:
的1.txt,2.txt,3.txt
我需要逐个处理这三个文件,并且必须按文件名的顺序。(首先处理1.txt然后2.txt到最后3.txt)
我在连接器中使用service-overrides并扩展SftpMessageReceiver并覆盖poll()方法,在方法中我按顺序创建这些文件的名称。但它不起作用。谁能告诉我哪里出错了。
我写的班级
public class NewSftpMessageReceiver extends SftpMessageReceiver {
private SftpReceiverRequesterUtil sftpRRUtil = null;
public NewSftpMessageReceiver(SftpConnector connector,
FlowConstruct flow,
InboundEndpoint endpoint,
long frequency) throws
CreateException {
super(connector, flow, endpoint);
this.setFrequency(frequency);
sftpRRUtil = new SftpReceiverRequesterUtil(endpoint);
}
public NewSftpMessageReceiver(SftpConnector connector, FlowConstruct flow, InboundEndpoint endpoint)
throws
CreateException {
super(connector, flow, endpoint);
sftpRRUtil = new SftpReceiverRequesterUtil(endpoint);
}
@Override
public void poll() throws
Exception {
try {
String[] files = sftpRRUtil.getAvailableFiles(false);
//do something here.....
for (String file : files) {
if (getLifecycleState().isStopping()) {
break;
}
routeFile(file);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
配置文件如下
<sftp:connector name="incoming-mandate-connector"
archiveDir="${esb.archive.path}/mandate/incoming"
useTempFileTimestampSuffix="true"
autoDelete="true"
identityFile="${esb.incoming.sftp.identityFile}"
passphrase="${esb.incoming.sftp.passphrase}"
sizeCheckWaitTime="${esb.incoming.sftp.sizeCheckWaitTime}">
<service-overrides messageReceiver="com.xxy.NewSftpMessageReceiver"/>
</sftp:connector>
<sftp:endpoint name="incoming-mandate-ep"
address="${esb.incoming.connector}"
connector-ref="incoming-mandate-connector"
keepFileOnError="true" encoding="${esb.encoding}">
<file:filename-wildcard-filter pattern="${esb.incoming.filePattern}"/>
</sftp:endpoint>
像吹气一样流动
<flow name="process">
<quartz:inbound-endpoint name="quartz-endpoint" cronExpression="${esb.cronExpression}" jobName="incoming-mandate-job">
<quartz:endpoint-polling-job>
<quartz:job-endpoint ref="incoming-mandate-ep"/>
</quartz:endpoint-polling-job>
</quartz:inbound-endpoint>
<processor ref="mandate-processor"/>
<transformer ref="mandate-transformer"/>
<mulexml:jaxb-object-to-xml-transformer jaxbContext-ref="jaxb" name="mandate-jaxb-transformer"/>
<byte-array-to-string-transformer mimeType="application/xml"/>
<message-properties-transformer scope="outbound">
<add-message-property key="${esb.username}" value="${esb.password}"/>
</message-properties-transformer>
<outbound-endpoint ref= "mandate-service-ep"/>
</flow>
答案 0 :(得分:1)
您的消息接收器未被调用的原因是您有一个调用SFTP传输的Quartz端点,因此实际上您使用的是消息请求者,而不是接收者。
您需要创建自定义消息请求者而不是接收者以及自定义请求者工厂(创建请求者的实例)
您可以按如下方式对其进行配置:
<sftp:connector name="sftpConnector">
<spring:property name="serviceOverrides">
<spring:map>
<spring:entry key="requester.factory" value="your.package.YourCustomSftpRequesterFactory"/>
</spring:map>
</spring:property>
</ftp:connector>
