實戰mule(1)

首先到 http://mule.codehaus.org/ 網站下載mule解壓安裝到本地硬盤，例如E:\java\mule-1.3-rc2
其次我們在這個目錄下創建一個目錄testmule用於測試
然後我們在testmule下創建如下目錄
src ：存放源文件
classes：存放java class文件
conf：存放xml配置文件
bin：存放測試執行的批處理（*.bat）文件

1、通用環境的搭建
以爲爲監聽程序服務的接口和實現
Test.java

package org.lyj.mule;

public interface Test {
    public void echo(String name);
}


Service.java

package org.lyj.mule;

public class Service implements Test {
    public void echo(String name) {
        System.out.println("called="+name);
    }
}

從mule的sample下的任意一個例子的conf裏把 log4j.properties 複製到 testmule/conf下，其中的內容如下

#Mule default logging configuration
#Logs to stdout and file.  the log file is called mule.log and is stored in the directory
#that the mule server is executed in

log4j.rootCategory=error, stdout, file

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%-5p %d [%t] %c: %m%n

# Maintain alog file with a single file backup
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=mule.log
log4j.appender.file.MaxFileSize=10MB
#  Keep one backup file
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%-5p %d [%t] %c: %m%n

#You can set custom log levels per package here
log4j.logger.org.apache=WARN

#Switch to info to see Test suite lifecycle info
log4j.logger.org.mule.tck=WARN



2、File Provider的實現
在conf下新建一個配置文件 test-file-config.xml，內容如下

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE mule-configuration PUBLIC "-//SymphonySoft //DTD mule-configuration XML V1.0//EN"
                                "http://www.symphonysoft.com/dtds/mule/mule-configuration.dtd">

<mule-configuration id="file" version="1.0">
    <description>
        本測試由劉玉軍完整測試，如果有問題請訪問http://blog.csdn.net/lyj_china
    </description>
    <model name="test file">
        <mule-descriptor name="Service1" implementation="org.lyj.mule.Service">
            <inbound-router>
                <endpoint address="file:///D:/temp/">
                    <properties>
                        <property name="pollingFrequency" value="30000"/>
                        <property name="moveToDirectory" value="/D:/done"/>
                    </properties>
                </endpoint>
            </inbound-router>
        </mule-descriptor>
    </model>
</mule-configuration>

意思就是每隔30秒把文件從 d：/temp下移動到d：/done目錄下

在bin下面創建文件 testfile.bat，內容如下：

@echo off
REM There is no need to call this if you set the MULE_HOME in your environment properties
if "%MULE_HOME%" == "" SET MULE_HOME=..\..

REM Set your application specific classpath like this
SET CLASSPATH=%MULE_HOME%\testmule\conf;%MULE_HOME%\testmule\classes;

call %MULE_HOME%\bin\mule.bat -config ../conf/test-file-config.xml

SET MULE_MAIN=
SET CLASSPATH=

然後我們運行testfile.bat 啓動，正常啓動mule後，就可以定時把 temp目錄下的文件複製到done下了。
並且在mule運行界面會打印出文件的內容，也就是說我們在mule裏可以監控到整個文件流。
