How to import a spring application context into another application context?

Question

I have two spring application contexts. One is local to my application and the other is from one of the maven dependencies.

Now, my applicationContext.xml file look like this.

<import resource="classpath*:**/sample-applicationContext.xml" />

and I have <context:component-scan> in the sample-applicationContext.xml file which scans for components.

and Now, when I do the following..

ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml");
MyClass m=ctx.getBean(MyClass.class);

Unfortunately, when I get the MyClass object, the object is created however, I see that dependencies in MyClass are not injected.

The dependencies autowired in MyClass are the beans that are scanned using the <context:component-scan> in sample-applicationContext.xml file.

Is there any way to make use of multiple application contexts present in the Maven dependencies and autowire beans in them in my project classes?

I'm not sure about maven dependencies, but you are trying to do something like a cross-context using spring. Take a look at this link: http://blog.imaginea.com/cross-context-communication-between-web-applications/

that didn't work. I am getting the dependency bean object, when I call them using ApplicationContext object `ctx.getBean(MyDependencyBean.class)` but when autowiring `MyDependencyBean` in `MyClass`. It is not autowired. In `MyClass` the `MyDependencyBean` is made `transient` to avoid `NotSerializableException`. Is it the reason why the dependency is not autowired:? What is the solution? – JavaTechnical Feb 13 '15 at 16:55

the following way, you can load the multiple spring applicationContext files.

ApplicationContext context = 
new ClassPathXmlApplicationContext(new String[] {"sample-applicationContext.xml",   "applicationContext.xml"});

it will be good if you can post the applicationContext.xml , sample-applicationContext.xml and MyClass code segments here.
