passing value to custom annotation in java

I am using custom annotation with aspectj.

@TestLoggingAnnotation(setMessage = "I want to set value here")
public void get() {

    String retString = null;
    String message = "DEFAULT";

    if (message == "DEFAULT") {

        retString = "Default Logging";

    } else {

        retString = "Custom Logging";
    }
}

The above is just simple and sample code. My requirement is that I want to pass the parameter value after resulting from method.

In my case I want set retString value to setMessage in custom parameter.

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface TestLoggingAnnotation{
    String setMessage ();
}

now use reflection to extract and set method param i doubt we can do this with local varibles.

As of now, annotations can only take compile constants and cant be assigned values at runtime, though their value can be used at runtime using @Retention.
