I have a root context that have all business bean (it is the root context)
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<!-- Root Context: defines shared resources visible to all other web components -->
<context:annotation-config />
<context:component-scan base-package="it.mypack">
<context:exclude-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
</context:component-scan>
</beans>
and servlet-context that have only controller bean (it is a child of root)
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

I want to add a Configuration class in order to create some bean programmatically. My question is: these bean will be part of root-context or servlet-context?
My configuration:
@Configuration
public class AppConfig {
@Bean
public ArrayList<String> myBean() {
ArrayList<String> std=new ArrayList<String>();
std.add("ciao");
return std;
}
}
I ask this because I don't want to create duplicate beans. To not allow this issue if you read my context code the root context have enabled component scan for all components except controller and servlet-context have enabled component scan only for Controller... so my question is the bean ArrayList myBean (declared in my config class) have as context root or servlet-context? Are you sure that spring not create duplicate bean? Please, can you explain the behaviour?
