I have this very simple class :
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath*:/application-context-this-does-not-exist.xml"})
public class HTMLSourceExtractorImplTest {
@Autowired
ApplicationContext context;
@Test
public void test(){
String [] beans = context.getBeanDefinitionNames();
for(String bean : beans){
System.out.println(bean);
}
System.out.println("Testing");
}
}
This context file that is specified in classpath DOES NOT EXIST. I can put virtually any name I want and the code does not break. I mean the test runs just fine, as if that file really exists.
If I do a small change, from : classpath* to classpath , then it beaks, saying that this file does not exist, which is the behavior I would expect in the first case also.
Spring Version 3.2.3.RELEASE.
Can someone explain this weird behavior?
EDIT
Things from logs as suggested:
20:47:26,923 INFO [GenericApplicationContext] Refreshing org.springframework.context.support.GenericApplicationContext@3df6c65c: startup date [Fri Jun 07 20:47:26 PDT 2013]; root of context hierarchy
I even tried to output all beans from application context:
org.springframework.context.annotation.internalConfigurationAnnotationProcessor
org.springframework.context.annotation.internalAutowiredAnnotationProcessor
org.springframework.context.annotation.internalRequiredAnnotationProcessor
org.springframework.context.annotation.internalCommonAnnotationProcessor
org.springframework.context.annotation.ConfigurationClassProcessor.importAwareProcessor
Seems to me that in case of a wildcard, Spring will create a default empty Application Context

Quote from JavaDoc will probably answer your question:
/**
* Pseudo URL prefix for all matching resources from the class path: "classpath*:"
* This differs from ResourceLoader's classpath URL prefix in that it
* retrieves all matching resources for a given name (e.g. "/beans.xml"),
* for example in the root of all deployed JAR files.
* @see org.springframework.core.io.ResourceLoader#CLASSPATH_URL_PREFIX
*/
String CLASSPATH_ALL_URL_PREFIX = "classpath*:";
As there are no XML files matching the name application-context-this-does-not-exist.xml
on your classpath, your configuration is equal to @ContextConfiguration(locations={})
=> empty application context.
However when you use CLASSPATH_URL_PREFIX = "classpath:"
, that equals to saying "load this non-existing file" => error loading context configuration.
