Junit-Spring integration IOexception on console

[razazaran]

I have a question here. I am trying to access spring configuration file using junit, but it is failing before setUp() method with following errror:

10:33:21.494 INFO [main][org.springframework.integration.http.inbound.IntegrationRequestMappingHandlerMapping] Mapped "{[/getBillServiceImplReq],methods=[POST],params=[],headers=[],consumes=[],produces=[],custom=[]}" 
onto public abstract void org.springframework.web.HttpRequestHandler.handleRequest(javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse) throws javax.servlet.ServletException,java.io.IOException

---

here is my Junit:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:/WEB-INF/upperSI/http/servlet-config.xml" })
@WebAppConfiguration
public class RestGetServiceImplTest{
@Autowired
private WebApplicationContext webApplicationContext;

private MockMvc mockMvc;

/**
 * Set variables and Objects which are need to execute the test-case.
 * @throws IOException 
 */
@Before
public void setUp() throws Exception{
    this.mockMvc = MockMvcBuilders.webAppContextSetup(this.webApplicationContext).build();
        }

---

and servlet-config code im trying to access/load is :

<supported-methods="POST" path="/getBillServiceImplReq" mapped-request-headers="HttpHeaders.REQUEST_URL"/>

<!-- this is require to enrich the header to handle the content-type of 
    type "application/json" -->
<int:header-enricher input-channel="getBillServiceImplChannel"
    output-channel="getBillServiceReqJsonImplChannel">
    <int:header name="content-type" value="application/json"></int:header>
</int:header-enricher>

<int:chain input-channel="getBillServiceReqJsonImplChannel">
<!-- Transformer is required to map the JSON payload in the Java object 
    format which can be processed in the eChannel framework -->
<int:json-to-object-transformer type="com.nbad.echannel.common.model.GetBillType" object-mapper="jackson2JsonObjectMapper" />
 <!-- <int:transformer ref="loggingJSONRequest" method="logJSONRequest" /> -->
<int:service-activator>
    <bean class="com.nbad.echannel.service.account.impl.GetBillServiceImpl"><constructor-arg ref="getDepositType"></constructor-arg></bean>
</int:service-activator>    
/int:chain>

Hi @razazaran !

First of all I don't see in this issue any Spring Integration Groovy DSL relevant info. From other side I've just added MockMvc to the https://github.com/spring-projects/spring-integration/blob/master/spring-integration-http/src/test/java/org/springframework/integration/http/HttpProxyScenarioTests.java And it works well.

So, provide, please, more StackTrace on the matter and supply some test-case to reproduce what doesn't work.

And, please, pay attention that message is 10:33:21.494 INFO [main]. So, what's going on there?

Thank you. And let us know how we can help you more.

Thanks Artem!! see im trying to do integration testing of my spring-integration application. I have create Junit which loads application context using @ContextConfiguration(locations = { "classpath:/WEB-INF/servlet-config.xml" }), everything works fine and i get the required response in JSON, but when i see STS console, i see this exception in blue , which I have pasted above. This error comes even before setUp() method of junit is called. Looks like @contextConfiguration is unable to load Spring integration beans.

Application context :

Sorry, I don't use STS, but as I said it is just an INFO. Since you confirm that everything works well, may be you just configure a logger in the STS for the WARN on the org.springframework category.

Let us know and close this issue if you don't have anymore problems

[razazaran]

are these tags of spring integration in application context correct ?

[artembilan]

I don't see anything specific. Just found that MVC include as redundant

[razazaran]

Ok Many Thanks !!. Do you know how to debug the xml file so that I may know which spring integration element was called and which not.

[artembilan]

XML config can't be debugged, because it makes sense only on the parser phase. In the runtime all those XML components are translates to specific Java object. And they already can be debugged. I most cases they are MessageSource, MessageProducer or MessageHandler implementations. Please, read more about JavaConfig (http://docs.spring.io/spring-integration/docs/latest-ga/reference/html/configuration.html#annotations) to get more info about Spring Integration internals.

[razazaran]

Thanks for the info Artem. Cheers !! but this issue is still not resolved, though im getting proper response. : )

[razazaran]

and yes I have seen you replied to similar question on stacoverflow. http://stackoverflow.com/questions/24310609/spring-integration-http-endpoint-from-child-context-doesent-work

[artembilan]

Sorry, I thought your issue was about that INFO in the logs, but now you refer me to an issue, when DispatcherServlet is in the child ctx. For this purpose we really should have a separate ticket with proper info on the matter.

[razazaran]

how to find whether dispatcher servlet is in the ctx ?? im not sure ... can u figure out from my code.

[artembilan]

DispatcherServlet is, erm.., a Servlet in the web.xml of your web-app, or that one from Spring Boot, if you use spring-boot-starter-web, or that from JavaConfig for Servlet 3 spec. But as I said: this question isn't relevant to this ticket.

[razazaran]

when im trying to call spring integration code in xml... from junit class, i get this error.... I dont get any error when i deploy n then run SOAPUI tests. i want to do this testing from Junit, not soapui.

[artembilan]

OK. Let's come back to the start! Which error do you have from test? Share, please, full StackTrace.

[razazaran]

10:33:21.494 INFO [main][org.springframework.integration.http.inbound.IntegrationRequestMappingHandlerMapping] Mapped "{[/getBillServiceImplReq],methods=[POST],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public abstract void org.springframework.web.HttpRequestHandler.handleRequest(javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse) throws javax.servlet.ServletException,java.io.IOException

this is the error im getting on console.... nothjing else. this error does not stop the flow, and i get proper response in junit.

[artembilan]

It isn't error. It's just log message on the INFO level from the AbstractHandlerMethodMapping#registerHandlerMethod

this.handlerMethods.put(mapping, newHandlerMethod);
if (logger.isInfoEnabled()) {
    logger.info("Mapped \"" + mapping + "\" onto " + newHandlerMethod);
}

What is the reason to disturb us for nothing?

[razazaran]

sorry I forgot to share the error message. my bad. I dont have the error message right now.
