Problems with the first use of mule

Because we need to do something about data exchange and know about the mule, which we have seen before and has never used. I thought it would be easy to use it. Who knows there are a lot of problems with it and there is no one to discuss.

Requirement: synchronize local folders with FTP

Use mule version: 2.2.1

Problems encountered and solutions:

1. I don't know how to embed mule in Java.

Code:

            String configFile = "conf/mule-config.xml";            String[] configFileArr = new String[]{configFile};            MuleContextFactory muleContextFactory = new DefaultMuleContextFactory();            MuleContext context =                    muleContextFactory.createMuleContext(new SpringXmlConfigurationBuilder(configFileArr));            context.start();

Configuration:

<?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:vm="http://www.mulesource.org/schema/mule/vm/2.2"    xmlns:ftp="http://www.mulesource.org/schema/mule/ftp/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/vm/2.2 http://www.mulesource.org/schema/mule/vm/2.2/mule-vm.xsd       http://www.mulesource.org/schema/mule/file/2.2 http://www.mulesource.org/schema/mule/file/2.2/mule-file.xsd       http://www.mulesource.org/schema/mule/ftp/2.2 http://www.mulesource.org/schema/mule/ftp/2.2/mule-ftp.xsd">    <file:connector name="fileConnector" pollingFrequency="6000" />    <ftp:connector name="ftpConnector"/>    <model name="model">        <service name="service">            <inbound>                <file:inbound-endpoint path="/e:/tmp"                    connector-ref="fileConnector">                </file:inbound-endpoint>            </inbound>            <outbound>                <pass-through-router>                    <ftp:outbound-endpoint host="XXX.XXX.XXX.XXXX"                        port="21" user="3guser" password="3guser" outputPattern="#[ORIGINALNAME]"                        path="/tttt" connector-ref="ftpConnector">                    </ftp:outbound-endpoint>                </pass-through-router>            </outbound>        </service>    </model></mule>

　　　　

2. When the file to be uploaded is about 20 mb, the client will be disconnected and an error will be reported during mule operation.

Solution:

Add

<Object-to-byte-array-transformer/>
Problem Solving

3. files containing Chinese file names cannot be synchronized, and Chinese characters on the FTP server are garbled.

This problem has plagued me for a long time. It took me a lot of time, but it is still not solved very well. Sometimes it is effective and sometimes ineffective.

Download the mule-transport-FTP source code and modify ftpconnector. java.

In the public outputstream getoutputstream (immutableendpoint endpoint, mulemessage message) Method
// Outputstream out = client. storefilestream (filename );
Change to: outputstream out = client. storefilestream (new string (filename. getbytes ("GBK"), "iso8859-1 "));

Next step: Be sure to thoroughly understand the mule and use version 3.x.
