Multipart Http Sample

This sample demonstrates how you can send a multipart request to a Spring Integration's HTTP service using 2 scenarios:

1. Spring's RestTemplate
2. Spring Integration Http Outbound Gateway

It consists of two parts - Client and Server. There are two client programs:

1. MultipartRestClient. It uses Spring's RestTemplate to assemble and send multipart request
2. MultipartClientForHttpOutboundClient. It uses Spring Integration Http Outbound Gateway to send multipart request.

The interesting part about this client is the way it assembles the Multipart request using a plain old Map.

The Server is Spring Integration's HTTP endpoint configuration.

To run this sample:

1. Deploy project
   • If you are using STS and project is imported as Eclipse project in your workspace you can just execute Run on Server
   • You can also run mvn clean install and generate the WAR file that you can deploy the conventional way
2. run the simple test client program: org.springframework.integration.samples.multipart.MultipartClient

You should see the following output from the server:

INFO : ...MultipartClient - Successfully recieved multipart request: {company=[[Ljava.lang.String;@147e8bd9], company-logo=[org.springframework.integration.http.UploadedMultipartFile@f5e12]}
INFO : ...MultipartClient - company - SpringSource
INFO : org.springframework.integration.samples.multipart.MultipartClient - company-logo - as UploadedMultipartFile: spring09_logo.png
