How to restrict bean instantiation in spring mvc (other than profile)

I want to restrict the bean instantiation. Currently, In the web application we are using the spring active profile for client specific bean instantiation. But now i want to restrict some of the bean instantiation specific to environment as well. How can i acheive both at the same time? FYI, i have env build parameter which specify the environment as either dev, qa or prod.

You can use @Conditional as explained below

Step 1- Implement Condition.matches so as to specify when should the bean be created or not.

public class SomeCondition implements Condition {
    @Override
    public boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata) {
        String env = System.getProperty("env");
        return env !=null ? "dev".equals(env); // modify it as per requirement
    }
}

Step 2 - In the configuration class specify the above class as condition to decide the bean creation

@Configuration
public class SomeAppConfig {

    @Bean
    @Condition(SomeCondition.class)
    public MyBean myBean() {
      return new MyBean();
    }
}

P.S.: I assumed that you used Java config and env as system property.
