Spring plugin misses classes injected with @Bean method instead of @Component

[MFAshby]

There are 2 ways of doing dependency injection in Spring, either annotations on the classes to be inject with @Component and friends, or via @Configuration classes with @Bean methods.

It seems like some of the spring glowroot config explicitly looks for @Component annotation, which means that beans injected with @Bean methods aren't traced. Example code:

public class FooService {
  @Scheduled(fixedDelay = 100)
  public void fooSchedule() {
    System.out.println("Hi");
  }
}
...
@Configuration
public class FooConfig {
  @Bean fooService() {
    return new FooService();
  }
}
...
@Component
public class BarService {
  @Scheduled(fixedDelay = 100)
  public void barSchedule() {
    System.out.println("good morning");
  }
}

Only scheduled tasks from BarService would appear in glowroot under 'Background' transactions. The scheduled method in FooService is ignored.

I tried an alternative instrumentation approach like this;

{
  "className": "ScheduledMethodRunnable",
  "methodName": "run",
  "methodParameterTypes": [],
  "captureKind": "transaction",
  "transactionType": "Background",
  "transactionNameTemplate": "Spring scheduled: {{this.method}}",
  "traceEntryMessageTemplate": "Spring scheduled: {{this.method}}",
  "timerName": "spring scheduled"
}

but it didn't capture anything. For now I'm going to change my code to use @Component based injection instead; but this has the downside it is less flexible than @Bean based injection; since that can be used to inject any class without modifying the source.
