[SPRING] 어노테이션을 사용하는 Spring Bean 상속 Bean reference back issue
SPRING어노테이션을 사용하는 Spring Bean 상속 Bean reference back issue
봄 콩을 사용하여 상속 된 클래스를 초기화하고 싶습니다. 상속을 구현하는이 stackoverflow 질문을 따랐습니다. Spring 상속 - 주석하지만 예외가 발생합니다.
이것은 나의 부모 클래스이다.
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;
}
우리 아이 클래스는 다음과 같습니다.
@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
}
나는이 예외를 얻고있다.

==============================
1.내 의견으로는, 문제는 Spring이 같은 이름을 가진 두 개의 다른 빈을 생성하려고한다는 것이다. 기본적으로 @Component 어노테이션으로 @Configuration, @Service 등의 주석을 포함하는 bean을 정의하면 @Component 주석이 추가 된 @Component이므로 해당 이름은 camelCase의 클래스 이름입니다.
내 의견으로는, 문제는 Spring이 같은 이름을 가진 두 개의 다른 빈을 생성하려고한다는 것이다. 기본적으로 @Component 어노테이션으로 @Configuration, @Service 등의 주석을 포함하는 bean을 정의하면 @Component 주석이 추가 된 @Component이므로 해당 이름은 camelCase의 클래스 이름입니다.
@Bean 어노테이션을 사용하여 bean을 정의 할 때, 그 이름은 어노테이션 된 메소드의 이름입니다.
그래서 당신은 두 가지 일을 할 수 있습니다.
어노테이션 속성을 설정하여 Configuration bean 이름을 설정할 수있다.
@Configuration("maxUsersSAQOSScenarioResultAnalyzerFactory")@Bean 어노테이션이 적용된 메소드의 이름을 다른 것으로 변경하십시오.
