Mule 3.6.1实现ftp上传文件

1. 编写java类，该类的主要的目的是将文件转化为二进制

package com.sigmatrix.ftp.service;

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

import org.mule.api.MuleMessage;
import org.mule.api.transformer.TransformerException;
import org.mule.transformer.AbstractMessageTransformer;

public class CreateFile extends AbstractMessageTransformer{

     @Override
     public Object transformMessage(MuleMessage message, String outputEncoding)

               throws TransformerException {

          File file = new File("F:\\001.jpg");

          return getBytesFromFile(file);
     }
    
     public static byte[] getBytesFromFile(File f){ 
        if (f == null){ 
            return null; 
        } 
        try{ 
            FileInputStream stream = new FileInputStream(f); 
            ByteArrayOutputStream out = new ByteArrayOutputStream(1000); 
            byte[] b = new byte[1000]; 
            int n; 
            while ((n = stream.read(b)) != -1) 
                out.write(b, 0, n); 
                stream.close(); 
                out.close(); 
            return out.toByteArray(); 
        } catch (IOException e){ 
            e.printStackTrace(); 
        } 
        return null; 
    } 
}

2. 配置.xml文件

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

< mule xmlns:sftp = "http://www.mulesoft.org/schema/mule/sftp"

      xmlns:ftp = "http://www.mulesoft.org/schema/mule/ftp" xmlns:file = "http://www.mulesoft.org/schema/mule/file"

                 port = "21" path = "/home/wwwroot/ftpuser/upload/artVerification/art/mule/" user = "ftp_mssc_user"

                 password = "123456" responseTimeout = "10000" doc:name = "FTP" passive = "false" binary = "true" outputPattern = "#[message . outboundProperties . imageUrl]" />

        < expression-component doc:name = "Set Message To MQ" > payload = "{\"imgUrl\":\"http://192.168.1.211:86/upload/artVerification/art/mule/"+message.outboundProperties.imageUrl+"\"}"; ]]> expression-component >

流程图如下 ：

3. 这样执行就可以将选中文件上传到FTP服务器
