我正在尝试在Spring AOP程序中运行建议,但我不断收到此错误:

我的问题是我有原型豆,但我不确定(但我不确定)可能是此错误的原因。
除了通过AppFactory类注入的FXML文件控制器之外,我已将Beans声明为批注:
样本Home.fxml
文件控制器bean被注入,如下所示:
@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();
}
}
通过注释类声明的内容看起来像,例如:
@Component
@Scope("prototype")
@Entity
@Table(name = "ENTITY_OBJECT")
public class EntityObject extends RevEntity {
private String name;
public String getName() {
return name;
}
}
Aspect类如下所示:
@Aspect
public class SampleAopAspect {
@Before("execution(public String getName())")
public void timeUpdataedAdvice() {
System.out.println("Before method ->");
}
}
FXML文件如下所示:
<?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"

xsi:schemaLocation="http://www.springframework.org/schema/beans

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>
如何使建议方法运行,或者我错了?谢谢大家。
您的原型bean需要指定proxyMode,例如:
@Scope(proxyMode = ScopedProxyMode.TARGET_CLASS, value = "prototype")
