How to read spring-application-context.xml and AnnotationConfigWebApplicationContext both in spring mvc

Question

In case I want to read bean definitions from spring-application-context.xml, I would do this in web.xml file.

<context-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/applicationContext.xml </param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>

In case I want to read bean definitions through Java Configuration Class (AnnotationConfigWebApplicationContext), I would do this in web.xml

<servlet> <servlet-name>appServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextClass</param-name> <param-value> org.springframework.web.context.support.AnnotationConfigWebApplicationContext </param-value> </init-param> <init-param> <param-name>contextConfigLocation</param-name> <param-value> org.package.MyConfigAnnotatedClass </param-value> </init-param> </servlet>

How do I use both in my application. like reading beans from both configuration xml file and annotated class.

Is there a way to load spring beans in xml file while we are using AppConfigAnnotatedClass to instantiate/use rest of the beans.

This didnt work

Xml file defines bean as

<bean name="mybean" class="org.somepackage.MyBean"/>

Java Class Imports Resources as

@ImportResource(value = {"classpath:some-other-context.xml"}) @Configuration public class MyConfigAnnotatedClass { @Inject MyBean mybean; }

But mybean value is always null which ofcourse will give nullpointerexception when calling method on mybean.

You can annotate your @Configuration class with

@ImportResource(value = {"classpath:some-other-context.xml"}) @Configuration public class MyConfigAnnotatedClass { ... }

to have it import <beans> type xml contexts.

You can do the same thing the other way around. Your @Configuration class is also a @Component. If you have a <component-scan> that includes its package, all its declared beans will be added to the context. Alternatively, you can do

<bean name="myAdditionalConfig" class="org.somepackage.MyConfigAnnotatedClass" />

Note that package cannot be used as a name in the package structure.

@Suvasis XML might not show properly in comments. Please edit your question and add it as code there.
I have edited my question showing what I have tried but did not work. Could you tell me how did you import the bean in @Configuration class. or where did you place your xml file.
@Suvasis If MyConfigAnnotatedClass is the class you've specified in the contextConfigLocation param, then what you have should work. This xml file should be a separate from the one loaded by the ContextLoaderListener.
