在此Spring应用程序的Linux上执行问题，该问题通过Spring Integration FTP在FTP服务器上上传文件：MessagingException

Question

I am pretty new in Spring and I have the following situation.

I have implemented a simple console Spring application that perform the upload of a file into an FTP server using Spring Integration FTP project: http://docs.spring.io/spring-integration/reference/html/ftp.html

So I have:

1) MainApp class:

public class MainApp {
   public static void main(String[] args) {
      ApplicationContext context = new ClassPathXmlApplicationContext("Beans.xml");

      HelloWorld obj = (HelloWorld) context.getBean("helloWorld");

      obj.getMessage();

      MessageChannel ftpChannel = context.getBean("ftpChannel", MessageChannel.class);
      File file = new File("C:\\test.txt");
      Message<File> fileMessage = MessageBuilder.withPayload(file).build();
      ftpChannel.send(fileMessage);
      ((AbstractApplicationContext) context).close();
   }
}

2) And this is the Beans.xml configuration file in which I configure the FTP connection:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:int-ftp="http://www.springframework.org/schema/integration/ftp"
    xmlns:int="http://www.springframework.org/schema/integration"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/integration/ftp http://www.springframework.org/schema/integration/ftp/spring-integration-ftp-4.2.xsd
        http://www.springframework.org/schema/integration http://www.springframework.org/schema/integration/spring-integration-4.2.xsd">

    <bean id="helloWorld" class="it.myCompany.myProject.batch.HelloWorld">
       <property name="message" value="Hello World!"/>
    </bean>

    <bean id="ftpClientFactory" class="org.springframework.integration.ftp.session.DefaultFtpSessionFactory">
        <property name="host" value="MY HOST"/>
        <property name="username" value="USERNAME"/>
        <property name="password" value="PSWD"/>
        <property name="clientMode" value="0"/>
        <property name="fileType" value="2"/>
        <property name="bufferSize" value="10000"/>                 
    </bean>

<int:channel id="ftpChannel"/>

<!--  
<int-ftp:outbound-channel-adapter
                id="sendFileToServer"
                auto-create-directory="true"
                session-factory="ftpSessionFactory"
                remote-directory="/test"/>
-->

<int-ftp:outbound-channel-adapter id="outFtpAdapter"
                                channel="ftpChannel"
                                session-factory="ftpClientFactory"
                                remote-directory="/home/myFolder"/>



</beans>

From my local Windows machine (performin it from Eclipse) it works fine and the selected file is putted into the /home/myFolder directory on my FTP server.

The problem is that I have to perform it as an runnable JAR file on a Linux machine.

So I have simply change this line of the MainApp class:

File file = new File("C:\\test.txt");

in this way:

File file = new File("/home/myUser/provaVPC.txt");

(in this way I simply select a specific .txt file into the Linux filesystem).

And then I exported my project as a runnable JAR file (so it contains all the required dependencies needed to work).

So I put the obtained jar file into the Linux machine but when I try to perform it in this environment I obtain the following error message:

So it seems that, from this Linux environment, it can't send the file because the obtained exception is:

Caused by: org.springframework.messaging.MessagingException: Failed to write to '/home/eds/provaVPC.txt.writing' while uploading the file; nested exception is java.io.IOException: Failed to write to '/home/eds/provaVPC.txt.writing'. Server replied with: 500 Illegal PORT command.

How is it possible if from the Windows environment works fine. I think that the problem is not in the File object creation from a textual file on the file system but it happens when this File object is sended a Message to my FTP server. But why? What can be the cause of this problem? How can I try to solve this issue? What am I missing?

Answer 1

You need to switch to passive mode, because DefaultFtpSessionFactory use active mode by default. In your config use clientMode 2
