Problem
In a large project structure, the Spring’s bean configuration files are located in different folders for easy maintainability and modular. For example,Spring-Common.xml in common folder,Spring-Connection.xml in connection folder,Spring-ModuleA.xml in ModuleA folder…and etc.
You may load multiple Spring bean configuration files in the code :
ApplicationContext context = new ClassPathXmlApplicationContext(new String[] {"Spring-Common.xml", "Spring-Connection.xml","Spring-ModuleA.xml"});
Put all spring xml files under project classpath.
project-classpath/Spring-Common.xml
project-classpath/Spring-Connection.xml
project-classpath/Spring-ModuleA.xml
Solution
The above ways are lack of organizing and error prone, the better way should be organized all your Spring bean configuration files into a single XML file. For example, create a Spring-All-Module.xml file, and import the entire Spring bean files like this :
File : Spring-All-Module.xml
<?xml version="1.0"?>
<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="common/Spring-Common.xml" />
<import resource="connection/Spring-Connection.xml" />
<import resource="moduleA/Spring-ModuleA.xml" />
</beans>
Now you can load a single xml file like this :
ApplicationContext context = new ClassPathXmlApplicationContext(Spring-All-Module.xml);
Put this file under project classpath.
project-classpath/Spring-All-Module.xml
Note In Spring3, the alternative solution is using JavaConfig
@Import.
