Spring (4)-how to load multiple Spring bean configuration file

problem

In a large project structure, the Spring ' s bean configuration files is located at different folders for easy Maintainabil ity 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 could load multiple Spring bean configuration files in code:

ApplicationContext context = 
    	new Classpathxmlapplicationcontext (new string[] {"Spring-common.xml",
              " Spring-connection.xml "," Spring-modulea.xml "});

Or 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 is lack of organize and error prone, the better of the should is organize all your Spring bean configuration Files into a single XML file. For example, create Aspring-all-module.xml file, and import the entire Spring bean files like this:

File:spring-all-module.xml

<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, can load a single XML file like this:

ApplicationContext context = 
    		new Classpathxmlapplicationcontext (Spring-all-module.xml);

	Or put this file under Project Classpath.

	Project-classpath/spring-all-module.xml

Note
In Spring3, the alternative solution is using Javaconfig @Import.
