本文提供了一个在Mule环境下动态修改Outbound Router的endpoint的示例，通过改变文件路径实现实时文件移动操作。代码展示了如何在运行时创建、复制并更新endpoint，以及如何将新的endpoint添加到Outbound Router中。

这次是在Outbound中动态修改endpoint。以文件的移动为例。上代码：

file-config.xml

<? xml version="1.0" encoding="UTF-8" ?>
< mule xmlns ="http://www.mulesource.org/schema/mule/core/2.2"
      xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:file ="http://www.mulesource.org/schema/mule/file/2.2"
      xsi:schemaLocation ="
    http://www.mulesource.org/schema/mule/core/2.2 http://www.mulesource.org/schema/mule/core/2.2/mule.xsd
    http://www.mulesource.org/schema/mule/file/2.2 http://www.mulesource.org/schema/mule/file/2.2/mule-file.xsd
    " >

     < file:connector name ="fileConnector" streaming ="false" pollingFrequency ="1000" autoDelete ="true"
                    outputPattern ="#[ORIGINALNAME]" />

     < endpoint name ="origin" address ="file:///D:/testDir/1" connector-ref ="fileConnector" />
     < endpoint name ="target" address ="file:///D:/testDir/3" connector-ref ="fileConnector" />

     < model name ="testModel" >
         < service name ="testService" >
             < inbound >
                 < file:inbound-endpoint ref ="origin" />
             </ inbound >
             < outbound >
                 < pass-through-router >
                     < file:outbound-endpoint ref ="target" />
                 </ pass-through-router >
             </ outbound >
         </ service >
     </ model >
</ mule >
