hope this fix your issue In a web-app, we define the context config location for spring to initialize all the beans like this , you can use the prefix 'classpath:'

wish helps you You can use @Import annotation if using Java configurations or tag if using XMl configs. With this approach you can reuse import one Spring context into another one.
Link to documentation: http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#beans-java-using-import
code :
<import resource="classpath:application-config.xml"/>
@ImportResource("classpath:application-config.xml")

this one helps. Was able to solve it by having the class implement ApplicationContextAware
code :
public class ReloadConfig implements ApplicationContextAware{

private static Logger log = Logger.getLogger(ReloadConfig.class);


private Config config;

@Autowired
ApplicationContext applicationContext;

private ReloadConfig() {
    // Exists only to defeat instantiation.
    config = Config.getInstance();
}

public void reloadIfNotLoaded() throws ConfigurationException{

    CompositeConfiguration configuration = new CompositeConfiguration();

    if(config.getHealthFile() == null){

        log.info("Reloading Adding default properties found in config.properties");
        configuration.addConfiguration(new PropertiesConfiguration("config.properties"));


        ConfigurableApplicationContext configurableApplicationContext = (ConfigurableApplicationContext)getApplicationContext();
        configurableApplicationContext.refresh();
        setApplicationContext(configurableApplicationContext);
    }



}

public void setApplicationContext(ApplicationContext context) throws BeansException {
    applicationContext = context;
}

public ApplicationContext getApplicationContext() {
    return applicationContext;
}

What is a right way to initialize fields in Spring Beans?

wish helps you Assuming the value is a constant, the first option is the simplest to understand and works without Spring, simplifying unit testing.
The second and fourth option are more complex and introduce an unnecessary dependency on the Spring container without any benefit. The third option is outright bizarre, since you're using @Autowired and not performing dependency injection.

Any of those help I have a Spring webapp running on Java 5. This is was my applicationContext.xml file: , Spring can do this for you:
code :
@Component
public class MyComponent {
    @Autowired
    private final List<IChildren> children;

    ...
}
