Make a request scoped bean singleton when request-scope is not available

I have the following code to define a bean request scoped bean inside my Spring application.

@Bean       
@Scope(value = "request", proxyMode = ScopedProxyMode.TARGET_CLASS)
public MyBean myBean() {
    return new MyBean(); // actually it is a more complex initialization
}

But sometimes I will want to use the same bean in a offline application where request scope is not available, only singleton and prototype are.

Is there a way to make this same bean assume a singleton form when request is not available?

can you rely on a spring profile ? You could maybe extract the bean creation in a private method used by 2 @Bean with different @Scope and @Profile

Something like this :

@Bean     
@Profile('prod')    
@Scope(value = "request", proxyMode = ScopedProxyMode.TARGET_CLASS)
public MyBean myBeanProd() {
    return getMyBean()
}

@Bean   
@Profile('test')    
@Scope(value = "singleton", proxyMode = ScopedProxyMode.TARGET_CLASS)
public MyBean myBeanWithoutRequestScope() {
    return getMyBean()
}

privateMyBean getMyBean() {
    return new MyBean(); // actually it is a more complex initialization
}
