I want to initialise classes which are inherited using spring Bean. I have followed this stackoverflow question to implement inheritance Spring Inheritance - Annotation but I am getting exception
This is my parent class
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;
}
My child class is as follow
@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
}
I am getting this exception

A bean may inherit type-level metadata and members from its superclasses. Inheritance of type-level metadata by beans from their superclasses is controlled via use of the Java @Inherited meta-annotation. Type-level metadata is never inherited from interfaces implemented by a bean.
Here, @Bean instantiates two beans with ids the same as the method names and registers them within the BeanFactory (Spring container) interface. Next, we can initialize the Spring container and request any of the beans from the Spring container. This strategy also makes it simple to achieve dependency injection.
Spring @Bean Annotation is applied on a method to specify that it returns a bean to be managed by Spring context. Spring Bean annotation is usually declared in Configuration classes methods. In this case, bean methods may reference other @Bean methods in the same class by calling them directly.
@Bean is a method-level annotation and a direct analog of the XML <bean/> element. The annotation supports most of the attributes offered by <bean/> , such as: init-method , destroy-method , autowiring , lazy-init , dependency-check , depends-on and scope .
In my opinion, the problem is that Spring is trying to create 2 different beans with the same name. By default, when you define a bean with the @Component annotation (that includes other annotations like @Configuration, @Service, etc. since they are @Component annotated as well), its name is the class name in camelCase.
When you define a bean using the @Bean annotation, its name is the name of the annotated method.
So you can do two things
Either you can set the Configuration bean name by setting the annotation's property
@Configuration("maxUsersSAQOSScenarioResultAnalyzerFactory")
or change the @Bean annotated method's name to something else
