Outbound Channel Adaptor is not responding

[Mahendra Singh Kushwah]

Hi,

I am trying to print all lines of input file & then copy the input file to ouput directory. For that I am using the below configuration:

 <channel id="message.inbound" />
	<channel id="message.outbound" />
	<context:property-placeholder location="classpath:/Budetest.properties" />
   
   <file:inbound-channel-adapter id="mfInputFileProcessor"
		directory="file:${input.directory}" filename-pattern="message*">
		<poller id="mfInputPoller" fixed-delay="10" time-unit="SECONDS"/>
	</file:inbound-channel-adapter>	

	<file:file-to-string-transformer
		input-channel="mfInputFileProcessor"
		output-channel="mfInputFileParser" charset="UTF-8"
		delete-files="false" />

	<splitter input-channel="mfInputFileParser" ref="mFileHandler"
		method="extractLines" output-channel="message.inbound" />

	<beans:bean id="mFileHandler"
		class="com.test.project.brokerage.fileAdaptor.Utilities.FileHandler" />
		
	 <beans:bean id="printBudeMessage"
		class="com.test.project.brokerage.fileAdaptor.FileTransformerTest" />
				
	<splitter input-channel="message.inbound" ref="printBudeMessage"
		method="printLine" output-channel="message.outbound" />
	
	<file:outbound-channel-adapter id="filesOut"
			 channel="message.outbound"
             directory="${output.directory}"
             auto-create-directory="true"
             delete-source-files="false"/>

Its printing all the lines but not copying the input file to output directory.

Please advise.

Its printing all the lines but not copying the input file to output directory.

I am assuming your printLine method does that.

Can you post here the implementation of your class com.test.project.brokerage.fileAdaptor.FileTransfo rmerTest ?

Also explain us in brief if possible your use case, what you are expecting to happen if the above thing works successfully.

[Mahendra Singh Kushwah]

public class BUDeTransformerTest {

	private static Logger log = Logger.getLogger(BUDeTransformerTest.class);
	public void printLine(String payload) {
		log.info(payload.toString());
		System.out.println(payload.toString());
	}
}

I am expecting the above code should print each line of all the input files and copy them to the output directory.

[Amol Nayak]

Ok, let your printLine return a String and have

return payload;

at the end.

This is however, not what a splitter is intended for.

Also, how are you expecting the files to be written?

First try changing the signature of the method and return the string. Then see if the files are being written, what is the content of the files and what are the names of the files.
Let us know whats the result and what was your expectation.

Thanks Amol for this suggestion.

Its printing all the lines, however unfortunately its not copying all the lines to the output directory.

also I can see some strange behavior, in the output directory, as explained below:

I have provided input file message.csv, which has 4 lines. But in the output directory I get 2 files:

message.csv and message.csvnull

and both having 1 line, i.e. line no.1 and line no.4 respectively.

Please have a look at the attached files.(Please remove .txt extension from both the files. I have added it to upload these files)

Please advise.

[Mahendra Singh Kushwah]

The above files are the output files. The input file is attached below.(Please remove .txt extension):

[Amol Nayak]

Can you explain your use case?

[Mahendra Singh Kushwah]

In my Case:

I would like to read files from input directory, print all the lines and copy the files to the output directory.

[Amol Nayak]

Copy them as they are in the source folder in the output directory?
What do you plan to do with the splitter, is there some processing you'll be doing with each line?

[Mahendra Singh Kushwah]

I just want to print all the lines, So for that purpose i have used splitter.

Did I do something wrong ?

Please suggest the best way to do it. I am new to spring, so don't know much.
