java - Spring AOP 中的 Advise 方法错误

Question

我正在尝试在 Spring AOP 程序中运行建议，但我不断收到此错误:

我遇到的问题是我有原型(prototype)bean，我认为(但我不确定)可能是这个错误背后的原因。

我将 Bean 声明为注释，但通过 AppFactory 类注入(inject)的 FXML 文件 Controller 除外:

示例 Home.fxml 文件 Controller bean 被注入(inject)，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();
    }
}

通过注释类来声明的内容如下所示:

@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"
       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>

我怎样才能运行建议方法，或者我哪里出了问题？提前谢谢大家。

你的原型(prototype)bean需要指定一个proxyMode，例如:

@Scope(proxyMode = ScopedProxyMode.TARGET_CLASS, value = "prototype")
