ApplicationContext : getBean()

[fv967]

Hi,

I need to instantiate a collection of beans which needs to be added to a Global list.
So, I did the following:

// AppContext class has an instance of the ApplicationContext 
ApplicationContext ctx = AppContext.getApplicationContext();  
for () {
...
IbRequestRealTimeBarsController baseRetrieve = (IbRequestRealTimeBarsController)     ctx.getBean("IbRequestRealTimeBarsController");
...
Global.currencyPairThreadList.add(baseRetrieve);
}

@Service
@Scope(BeanDefinition.SCOPE_PROTOTYPE)
public class IbRequestRealTimeBarsController {
...
}

The following exeption occurs:

org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'IbRequestRealTimeBarsController' is defined
    org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:553)

what did I do wrong or forget ?

Thank in advance,

Hi Frank,

Can you please post your configurations?

[amiladomingo]

When a component is autodetected as part of the scanning process, its bean name is generated by the BeanNameGenerator strategy known to that scanner. By default, any Spring stereotype annotation (@Component, @Repository, @Service, and @Controller) that contains a name value will thereby provide that name to the corresponding bean definition.

If such an annotation contains no name value or for any other detected component (such as those discovered by custom filters), the default bean name generator returns the uncapitalized non-qualified class name. For example, if the following two components were detected, the names would be myMovieLister and movieFinderImpl:

Please read following section on Spring documentation http://static.springsource.org/sprin...name-generator

Have you read the link he posted? The bean name is wrong it starts with a lowercase letter (classname with first letter lowercased).

[fv967]

Many thanks for reply, will put on lowercase and test later today when back in office.

[fv967]

I changed the class name to lowercase, and now it works : ctx.getBean("ibRequestRealTimeBarsController")

Many thanks,

Frank
