<title>Multipart HTTP request - RestTemplate (client) and Http Inbound Gateway (server)</title>
<para>
This example demonstrates how simple it is to send a Multipart HTTP request via Spring's RestTemplate and receive it by Spring Integration HTTP Inbound Adapter.
All we are doing is creating <classname>MultiValueMap</classname> and populating it with multi-part data. <classname>RestTemplate</classname> will take care of the rest
by converting it to <classname>MultipartHttpServletRequest</classname>  
THis particular client will send a multipart Http Request which contains the name of the company as well as the image file with company logo.
<programlisting language="java"><![CDATA[RestTemplate template = new RestTemplate();
String uri = "http://localhost:8080/multipart-http/inboundAdapter.htm";
Resource s2logo = 
new ClassPathResource("org/springframework/integration/samples/multipart/spring09_logo.png");
MultiValueMap map = new LinkedMultiValueMap();
map.add("company", "SpringSource");
map.add("company-logo", s2logo);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(new MediaType("multipart", "form-data"));
HttpEntity request = new HttpEntity(map, headers);
ResponseEntity<?> httpResponse = template.exchange(uri, HttpMethod.POST, request, null);]]></programlisting>
</para>
<para>
That is all for the client.
</para>
<para>
On the server side we have the following configuration:
<programlisting language="xml"><![CDATA[<int-http:inbound-channel-adapter id="httpInboundAdapter"
channel="receiveChannel"
name="/inboundAdapter.htm"
supported-methods="GET, POST" />
<int:channel id="receiveChannel"/>
<int:service-activator input-channel="receiveChannel">
<bean class="org.springframework.integration.samples.multipart.MultipartReceiever"/>
</int:service-activator>
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>
]]></programlisting>
</para>
<para>
The 'httpInboundAdapter' will receive the request, convert it to a <classname>Message</classname> with a payload as <classname>LinkedMultiValueMap</classname> which
we are parsing in the 'multipartReceiver' service-activator;
<programlisting language="java"><![CDATA[public void recieve(LinkedMultiValueMap<String, Object> multipartRequest){
System.out.println("### Successfully recieved multipart request ###");
for (String elementName : multipartRequest.keySet()) {
if (elementName.equals("company")){
System.out.println("\t" + elementName + " - " +
((String[]) multipartRequest.getFirst("company"))[0]);
} else if (elementName.equals("company-logo")){
System.out.println("\t" + elementName + " - as UploadedMultipartFile: " +
((UploadedMultipartFile) multipartRequest.getFirst("company-logo")).getOriginalFilename());
}
}
}
]]></programlisting>
You should see the following output:
<programlisting language="xml"><![CDATA[### Successfully recieved multipart request ###
company - SpringSource
company-logo - as UploadedMultipartFile: spring09_logo.png]]></programlisting>
