restTemplate + POST request + parse the response

[ronak]

Hi All,

I am using spring restTemplate to access the rest webservice, I am able to access the rest webservice with GET request, like I am able to receive the xml responce and able to parse to java.util.List with my bean class. But I am not able to get responce from POST request, as I guess still i am not much clear how to pass parameter while placing POST request. Can anyone please share the links with good examples of POST request using restTemplate. i searched on net but didn't got any useful stuff.

Below is scenario, plz let me know your suggestions, which will help out me a lot...

URL which i need to hit where webservice is hosted

http://localhost:8080/customer-ws/Customer/Utils/getAllCustomers

I need to pass the request, for testing I am using curl and passing my request object as below

<?xml version="1.0" encoding="utf-16"?>
<GetAllCustomersRequest xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:xsd="http://www.w3.org/2001/XMLSchema" location="1">
</GetAllCustomersRequest>

if i use curl, i get below response.

<?xml version="1.0" encoding="UTF-8"?>
<GetAllCustomerResponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:xsd="http://www.w3.org/2001/XMLSchema" customerCount="3">
	<returnResponse returnCode="0"></returnResponse>
	<customer balance="1.0" custId="Cust-Id0"  custName="CustName0"></customer>
	<customer balance="5.0" custId="Cust-Id2"  custName="CustName2"></customer>
	<customer balance="8.0" custId="Cust-Id4"  custName="CustName4"></customer>
</GetAllCustomerResponse>

below is my spring xml file code snippet

	<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
		<property name="messageConverters">
			<list>
				<bean id="messageConverter" class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
					<property name="marshaller" ref="xstreamMarshaller" />
					<property name="unmarshaller" ref="xstreamMarshaller" />
				</bean>
			</list>
		</property>
	</bean>
	<bean id="xstreamMarshaller" class="org.springframework.oxm.xstream.XStreamMarshaller">
		<property name="aliases">
			<props>
				<prop key="customer">com.test.ws.Customer</prop>
			</props>
		</property>
	</bean>

here is curl call from command prompt which generate test-respose.txt with above mentioned xml responce.

curl -X POST -d @GetAllCustomersRequest.xml -H "Content-Type:text/xml" http://localhost:8080/customer-ws/Customer/Utils/getAllCustomers > test-respose.txt

Can any one helpout with basic code snippet, how can I use restTemplate to place POST request for above scenario, and to get the responce in java.util.List<Customer>

Thanks for your time and any suggestion, plz let me know if any more information required....

It seams like a Post is being mixed with a Get.

Should you be doing one or the other. Post to make a change & possible retrieve a url to the updated object, And a Get to retrieve the object.

Or am I missing somthing?

Thanks for your time...

Yes you are correct it should be in that way, but the rest webservice which i need to access it works with POST request only, and I am developing app to consume it, so I can not change it ,,,, functionality looks the same way it suppose to work with GET request but WS understand only POST request, and my query is what shall I pass as POST request, I observed there is method postForObject, but in my scenario as I have given code sinppets above what shall I pass ??

Appriciate any hint/suggestion which can help me to move fwd ....
