Testing using @ContextConfiguration and XmlWebApplicationContext and dwr

[kamilski81]

I am currently performing testing using the XmlWebApplicationContext() ->

XmlWebApplicationContext ctx = new XmlWebApplicationContext();
				ctx.setConfigLocations(new String[]{"trident-resend-servlet.xml", "applicationContext-itest.xml"});
				ctx.setServletContext(new MockServletContext(""));
				ctx.refresh();

However, I am trying to convert to annotations using :

@ContextConfiguration(locations={"/trident-resend-servlet.xml", "/applicationContext-itest.xml"})


Dwr requires that I use XmlWebApplicationContext() to perform the spring Dependency injections and i am getting the following error when using @ContextConfiguration...what would be a workaround?

Dwr requires that I use XmlWebApplicationContext() to perform the spring Dependency injections and i am getting the following error when using @ContextConfiguration...what would be a workaround?

See the following JIRA issue and related forum threads (i.e., the links in the JIRA issue comments): https://jira.springsource.org/browse/SPR-5243

After analizing the stack trace I found that the error happened because org.directwebremoting.spring.DwrController is inheriting from org.springframework.web.context.support.WebApplica tionObjectSupport, a class that requires a web context, so the solution is to create two xxx-servlet.xml and a class to override the default DwrController behaviour when starting.

Solution

First, create somewhere in your project.

DwrControllerWithTestSupport.java

public class DwrControllerWithTestSupport extends DwrController {


@Override
public void afterPropertiesSet() throws Exception {
// overriding and doing nothing
}
}

Then in xxx-servlet-test.xml just override the dwrController declaration and this way you will get this second bean instantiated in testing environment.

<bean id="dwrController" class="pe.gob.hndac.kardex.web.dwr.DwrControllerWi thTestSupport">
</bean>


Then, in you web tests superclass:

@ContextConfiguration(locations = { "classpath:xxx-servlet.xml", "classpath:xxx-servlet-test.xml" },inheritLocations = true)
@Ignore
public class WebBaseContextSensitiveTest extends AbstractJUnit4SpringContextTests{

}

Note: I think this is a valid approach if you are declaring dwrController this way in xxx-servlet.xml

<dwr:controller id="dwrController" debug="true" />

or

with the old fashion way:

<bean id="dwrController" class="org.directwebremoting.spring.DwrController" >
<property name="configurators">
<list>
<ref bean="dwrConfiguration" />
</list>
</property>
<property name="debug" value="true" />
</bean>

<bean id="dwrConfiguration" class="org.directwebremoting.spring.SpringConfigur ator">
<property name="creators">
<map>
...
</map>
</property>
</bean>
