Spring Bean Vererbung mit Annotationen Bean Referenz zurück Ausgabe

Ich möchte Klassen initialisieren, die mit Spring Bean vererbt werden. Ich habe diese Frage Stackoverflow gefolgt Erbe zu implementieren Spring Inheritance - Annotation aber ich bin immer AusnahmeSpring Bean Vererbung mit Annotationen Bean Referenz zurück Ausgabe

Das ist meine Elternklasse

public class DefaultScenarioResultAnalyzer implements ScenarioResultAnalyser, CommonConstants{ 
@Autowired 
NotificationEmail notificationEmail; 

@Bean 
public DefaultScenarioResultAnalyzer defaultScenarioResultAnalyzer() { 
    return new DefaultScenarioResultAnalyzer(); 
} 

public DefaultScenarioResultAnalyzer() { 
} 

public DefaultScenarioResultAnalyzer(ScenarioResult scenarioResult) { 
    this.scenarioResult = scenarioResult; 
    this.scenarioId = scenarioResult.getScenarioId(); 
    this.scenarioIdAsString = SCENARIO_FILE_PREFIX + scenarioId; 
}

Mein Kind Klasse als

@Configuration 
public class MaxUsersSAQOSScenarioResultAnalyzer extends DefaultScenarioResultAnalyzer { 

private ScenarioResult scenorioResult; 

@Bean 
public MaxUsersSAQOSScenarioResultAnalyzer maxUsersSAQOSScenarioResultAnalyzer(){ 
    return new MaxUsersSAQOSScenarioResultAnalyzer(); 
} 

public MaxUsersSAQOSScenarioResultAnalyzer() { 
} 

public MaxUsersSAQOSScenarioResultAnalyzer(ScenarioResult scenarioResult) { 
    super(scenarioResult); 
    this.scenorioResult= scenarioResult; 
    setSuccessEmailTemplateId("velocity/scenario/maxusers-saqos-scenario-success.vm"); 
    //scenario failure: use DefaultScenarioResultAnalyzer.failureEmailTemplateId 
}

ich diese Ausnahme bin immer folgen

Meiner Meinung nach ist das Problem, dass Spring versucht, 2 verschiedene Bohnen mit dem gleichen Namen zu erstellen. Wenn Sie eine Bean mit der Annotation @Component definieren (die weitere Annotationen wie @Configuration, @Service usw. enthält, da sie ebenfalls mit @Component kommentiert sind), ist ihr Name der Klassenname in camelCase.

Wenn Sie eine Bean mit der @Bean Annotation definieren, ist ihr Name der Name der mit Annotationen versehenen Methode.

So kann man zwei Dinge tun

Entweder Sie können die Configuration Bean Namen festlegen, indem der Unterkunft Anmerkung Einstellung

@Configuration("maxUsersSAQOSScenarioResultAnalyzerFactory")

oder die @Bean kommentierten Methode Namen auf etwas anderes ändern
