ule子-使用文件连接器删除文件 [英] Mule - Delete files with Files Connector

问题描述

这是我的主要mule flow:

HTTP > Payload > File (Create) > Property (File Name) JMS

JMS调用以JMS开头的other flow

JMS > JSON TO XML > File (Delete by file name)

首先，我用JSON消息创建一个文件.

最后，当JSON消息转换为XML时，我尝试通过名称调用属性来删除文件，该文件告诉我名字. /p>

但是文件不会删除.它通过日志输出此操作:

Writing file to: C:\errors\91fa03a0-dd33-11e5-a0d9-408d5c4c1bf3.dat

如何删除它?

我尝试使用Connector Configuration中的选项 autoDelete ，但不会删除.

<file:connector name="File1" outputPattern="#[message.inboundProperties.fileName]" autoDelete="true" streaming="false" validateConnections="true" doc:name="File"/>

解决方案

您不能使用此文件出站终结点来删除文件.

例如，如果您将使用S3之类的东西，则可以，但是这些连接器是基于操作的".

这是要写入一个新文件或将数据追加到现有文件中.

autoDelete选项用于在文件入站端点读取文件后将其删除.

如果要删除，并在用例中使用Java代码，请使用File类中的方法: https://docs.oracle.com/javase/7 /docs/api/java/io/File.html

This is my main mule flow:

HTTP > Payload > File (Create) > Property (File Name) JMS

And that JMS calls to other flow that starts with JMS

JMS > JSON TO XML > File (Delete by file name)

Firstly, I create a file with the JSON message.

And finally, when JSON message is transformed to XML, I try to delete the file by name calling a property that tell me the name.

But the files doesn't delete. Its output this action by log:

Writing file to: C:\errors\91fa03a0-dd33-11e5-a0d9-408d5c4c1bf3.dat

How can I do to delete it?

I tried with the option autoDelete in the Connector Configuration but it doesn't delete.

<file:connector name="File1" outputPattern="#[message.inboundProperties.fileName]" autoDelete="true" streaming="false" validateConnections="true" doc:name="File"/>

解决方案

You can't use this file outbound endpoint to delete a file.

If you would use something like S3 for example you can, but those connectors are 'operation-based'.

It's meant to write an new file or append data to an existing one.

The autoDelete option is for deleting the file once it has been read by a file inbound endpoint.

If you want to delete and for your usecase you should use a piece of JAVA code and use methods from the File Class: https://docs.oracle.com/javase/7/docs/api/java/io/File.html
