Override LocalStatelessSessionProxyFactoryBean without xml configuration

Question

First the question, then the explanation: I want to get rid of the Beans XML configuration and add some info to my EJB contexts.

I've here in my project (web part of the project) a class named StatelessEjbSupportLocal which extends LocalStatelessSessionProxyFactoryBean and this is the implementation:

public class StatelessEjbSupportLocal 
        extends LocalStatelessSessionProxyFactoryBean {

    private UserInfo userInfo;

    @Override
    public Object invoke(MethodInvocation invocation) throws Throwable {
        FacesContext context = FacesContext.getCurrentInstance();
        Properties properties = new Properties();
        properties.put(Context.INITIAL_CONTEXT_FACTORY, 
             "org.jboss.security.jndi.JndiLoginInitialContextFactory");
        properties.put(Context.PROVIDER_URL, "jnp://localhost:1099/");
        properties.put(Context.SECURITY_PRINCIPAL, 
                userInfo.getLogin() + ";" + userInfo.getHost());
        properties.put(Context.SECURITY_CREDENTIALS, userInfo.getIdUser());
        super.setJndiEnvironment(properties);
        refreshHome();
    }
    public UserInfo getUserInfo() {
        return userInfo;
    }

    public void setUserInfo(UserInfo userInfo) {
        this.userInfo = userInfo;
    }
}

And I have on my apps.xml with the beans configuration:

(...)
<context:annotation-config/>
<context:component-scan base-package="my.package.controller" />

<bean id="someBusiness" class="my.package.StatelessEjbSupportLocal">
    <property name="jndiName" value="SomeBusinessImpl/local" />
    <property name="businessInterface" value="my.package.business.SomeBusiness" />
    <property name="userInfo" ref="userInfo" />
</bean>
(...)

My web.xml has the configuration to load the above xml:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:apps.xml</param-value>
</context-param>

My UserInfo class is annotated with @Component and is filled on my SecurityFilter (configured on my web.xml as a filter) after the users login. I set the host, login and the id there and put it on the session.

It is all working fine. I have this because I set the user on the EJB SessionContext to get this info on an Interceptor on my Business (services) classes. That way I don't need to handed pass the user info to all my business implementations (I need this because on my connection I set the user info to the database with a procedure like some kind of pre-connection configuration to audit purposes).

What I would like to do is to get rid of the beans XML configuration on my apps.xml. In other words some kind of interceptor to this LocalStatelessSessionProxyFactoryBean that would set the UserInfo without the need of <property name="userInfo" ref="userInfo" /> on every bean configuration. Since I can have my apps.xml with just this:

<context:annotation-config/>
<context:component-scan base-package="my.package.controller" />

And my SomeBusiness attribute on my managed bean annotated with @Autowired will work just fine.

Let me know if you need more information and I will edit this question with it.

Thanks in advance.

This isn't pretty and I don't recommend it. You should either use a @Bean annotated method to construct the bean or keep your XML.

If you want still want to go ahead with this, annotate your StatelessEjbSupportLocal class with @Component. Annotate its setUserInfo with @Autowired and override the setBusinessInterface and setJndiName methods, annotating them with @Value with the value you want to use, and calling their super implementation. For example,

@Override
@Value("SomeBusinessImpl/local") // or reference some property
public void setJndiName(String jndiName) {
    super.setJndiName(jndiName);
}

Then declare the package containing StatelessEjbSupportLocal in your component scan.

Edit By OP:

As Sotirios Delimanolis recommended. I left the XML configuration.
