问题
I'm trying to run an advise in a Spring AOP program but I keep getting this error:
Exception in Application start method

The problem I have is that I have prototype beans which I think (But I'm not certain) might be behind this error.
I have my Beans declared as annotations, except for the FXML file controllers which are injected via an AppFactory class:
a sample Home.fxml
file controller bean gets injected like so:
@Configuration
public class AppFactory {
@Bean
public HomeController homeController() throws IOException {
return (HomeController) loadController("/Home.fxml");
}
FXMLLoader loader = null;
protected Object loadController(String url) throws IOException {
loader = new FXMLLoader(getClass().getResource(url));
loader.load();
return loader.getController();
}
}
The ones declared by annotating a class look like, for example:
@Component
@Scope("prototype")
@Entity
@Table(name = "ENTITY_OBJECT")
public class EntityObject extends RevEntity {
private String name;
public String getName() {
return name;
}
}
The Aspect class looks like:
@Aspect
public class SampleAopAspect {
@Before("execution(public String getName())")
public void timeUpdataedAdvice() {
System.out.println("Before method ->");
}
}
The FXML file looks like:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd ">
<aop:aspectj-autoproxy />
<bean id="sampleAopAspect" class="org.SampleAopAspect" />
<context:annotation-config/>
<context:component-scan base-package="wakiliproject"/>
</beans>
How can I make the advice methods to run, or whare am I going wrong? Thank you all in advance.

Your prototype beans need to specify a proxyMode, e.g.:
@Scope(proxyMode = ScopedProxyMode.TARGET_CLASS, value = "prototype")
