实战mule(1)

首先到 http://mule.codehaus.org/ 网站下载mule解压安装到本地硬盘，例如E:\java\mule-1.3-rc2
其次我们在这个目录下创建一个目录testmule用于测试
然后我们在testmule下创建如下目录
src ：存放源文件
classes：存放java class文件
conf：存放xml配置文件
bin：存放测试执行的批处理（*.bat）文件

1、通用环境的搭建
以为为监听程序服务的接口和实现
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);
    }
}

从mule的sample下的任意一个例子的conf里把 log4j.properties 复制到 testmule/conf下，其中的内容如下

#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的实现
在conf下新建一个配置文件 test-file-config.xml，内容如下

<?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>
        本测试由刘玉军完整测试，如果有问题请访问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秒把文件从 d：/temp下移动到d：/done目录下

在bin下面创建文件 testfile.bat，内容如下：

@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=

然后我们运行testfile.bat 启动，正常启动mule后，就可以定时把 temp目录下的文件复制到done下了。
并且在mule运行界面会打印出文件的内容，也就是说我们在mule里可以监控到整个文件流。
