Mule 学习系列<二> File Transport

 

Mule提供一种方式，将某个路径下面的文件传送到某个指定的路径下。这种传输通道就是File Transport.

File Transport提供一系列可配置的属性，来提高它的实用性。

   

   

属性	类型	目标	描述
writeToDirectory	String	connector, outbound endpoin	文件输出的目录
readFromDirectory	String	connector, inbound endpoin	文件输入的目录
autoDelete	boolean	connector, inbound endpoint	文件传输之后是否删除源文件目录文件
outputAppend	boolean	connector, outboun endpoint
pollingFrequency	long	connector, inbound endpoint	每个多长时间传输（以毫秒为单位）
moveToDirectory	String	connector, inbound endpoint
moveToPattern	String	connector, inbound endpoint	传输文件名模式
outputPattern	String	connector, outbound endpoint	输出文件名模式
streaming	boolean	connector	是否把文件做为流处理

File Transport 实例：

1. 将文件从指定的源目录拷贝到目的目录,拷贝完之后删除源目录中的文件:

   <?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:spring="http://www.springframework.org/schema/beans"
          xmlns:stdio="http://www.mulesource.org/schema/mule/stdio/2.2"
          xmlns:file="http://www.mulesource.org/schema/mule/file/2.2"
          xsi:schemaLocation="
                  http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
                  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/stdio/2.2 http://www.mulesource.org/schema/mule/stdio/2.2/mule-stdio.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="false">
              <file:expression-filename-parser/>
          </file:connector>        
          
          <model name="fileMode">
              <service name="fileService">
                 <inbound>
                    <file:inbound-endpoint path="/d:/test/data/snapshot"></file:inbound-endpoint>
                 </inbound>
                 <outbound>
                    <pass-through-router>
                       <file:outbound-endpoint path="/d:/test/data/archive" outputPattern="#[header:originalFilename]"> </file:outbound-endpoint>
                    </pass-through-router>
                 </outbound>
              </service>
          </model>
   </mule>

    

2. 指定的源目录中拷贝仅匹配通配符的文件到目的目录中

      

 

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <mule xmlns="http://www.mulesource.org/schema/mule/core/2.2"
 3        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4        xmlns:spring="http://www.springframework.org/schema/beans"
 5        xmlns:stdio="http://www.mulesource.org/schema/mule/stdio/2.2"
 6        xmlns:file="http://www.mulesource.org/schema/mule/file/2.2"
 7        xsi:schemaLocation="
 8                http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
 9                http://www.mulesource.org/schema/mule/core/2.2 http://www.mulesource.org/schema/mule/core/2.2/mule.xsd
10                http://www.mulesource.org/schema/mule/stdio/2.2 http://www.mulesource.org/schema/mule/stdio/2.2/mule-stdio.xsd
11                http://www.mulesource.org/schema/mule/file/2.2 http://www.mulesource.org/schema/mule/file/2.2/mule-file.xsd">
12        <file:connector name="fileConnector" streaming="false" pollingFrequency="1000" autoDelete="false">
13            <file:expression-filename-parser/>
14        </file:connector>        
15        
16        <model name="fileMode">
17            <service name="fileService">
18               <inbound>
19                  <file:inbound-endpoint path="/d:/test/data/snapshot">
20                        <!--只拷贝后缀名为txt的文件到archive目录中--> 
21                        <file:filename-wildcard-filter pattern="*.txt"/>
22                      </file:inbound-endpoint>
23               </inbound>
24               <outbo
25                  <pass-through-router>
26                     <file:outbound-endpoint path="/d:/test/data/archive" outputPattern="#[header:originalFilename]"> </file:outbound-endpoint>
27                  </pass-through-router>
28               </outbound>
29            </service>
30        </model>
31 </mule>
32
