Description
Bertrand Fovez opened SPR-6494 and commented
The tag <import resource="..."/> acts differently in version 3.0.0 and 2.5.6.
For example, consider these two xml configuration files, located in a package "context".
File: dependent-context.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<bean id="myBean" class="java.lang.String" />
</beans>
File: super-context.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<import resource="dependent-context.xml" />
</beans>
We load the latter, using the following:
new ClassPathXmlApplicationContext("context/super-context.xml");
Here is the log using Spring 2.5.6.SEC01:
11:47:58,903 INFO [ClassPathXmlApplicationContext] Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@19efb05: display name [org.springframework.context.support.ClassPathXmlApplicationContext@19efb05]; startup date [Wed Dec 02 11:47:58 CET 2009]; root of context hierarchy

Note that the dependent-context.xml file is loaded as "class path resource [context/dependent-context.xml]"
Here is the log using Spring 3.0.0.RC3:
12:06:57,312 INFO [ClassPathXmlApplicationContext] Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@8814e9: startup date [Wed Dec 02 12:06:57 CET 2009]; root of context hierarchy

12:06:57,795 INFO [DefaultListableBeanFactory] Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@1a9334: defining beans [myBean]; root of factory hierarchy
Note that the dependent-context.xml file is new loaded as "URL [file:/C:/Workspace/__Test/target/classes/context/dependent-context.xml]"
If the two file are located in different folders on the file system, as it is often the case, the loading fails.
This difference generates several major regressions in our existing projects.
Affects: 3.0 RC3
