java – 使用AspectJ的AOP在春天不工作？

我的Aspect课程将是,

@Configuration
@EnableAspectJAutoProxy
@Component
@Aspect
public class AspectClass {

    @Before("execution(* com.pointel.aop.test1.AopTest.beforeAspect())")
    public void logBefore(JoinPoint joinPoint) {

        System.out.println("Before running the beforeAspect() in the AopTest.java class!");
        System.out.println("Hijacked Method name : " + joinPoint.getSignature().getName());
        System.out.println("************************");
    }

}

我的其他java类

public class AopTest {

    public void beforeAspect() {
        System.out.println("This is beforeAspect() !");
    }
}

我的主要课程是

public class MainMethod {

    public static void main(String[] args) {    
        ApplicationContext context = new FileSystemXmlApplicationContext("ApplicationContext/applicationContext.xml");
        AopTest test = (AopTest)context.getBean("bean1");
        test.beforeAspect();
    }
}

我的applicationContext.xml是,

<?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:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
    http://www.springframework.org/schema/aop 
    http://www.springframework.org/schema/aop/spring-aop-3.0.xsd ">

    <bean id="bean1" class="com.pointel.aop.test1.AopTest" />

</beans>

在此,当运行Main方法时,AspectClass中的@Before(“execution(* com.pointel.aop.test1.AopTest.beforeAspect())”)将不会在AopTest中的beforeAspect()之前执行.

肯定赞赏好的答案.

解决方法:

首先,如果您要使用基于注释的配置,请使用AnnotationConfigApplicationContext而不是FileSystemXmlApplicationContext.并删除applicationContext.xml文件,只需在配置类中添加@Bean方法即可.像这样的东西：

@Configuration
@EnableAspectJAutoProxy
@ComponentScan(basePackages = "your.aspect.package")
public class AspectConfig {
    @Bean 
    public AopTest aopTest() {
        return new AopTest();
    }
}

在你的主要

public class MainMethod {

    public static void main(String[] args) {    
        AnnotationConfigApplicationContextcontext = new AnnotationConfigApplicationContext(AspectConfig.class);
        // don't forget to refresh
        context.refresh();
        AopTest test = (AopTest)context.getBean("aopTest");
        test.beforeAspect();
    }
}

在AspectClass中,你应该有@ Component,@ Aspect,你的方法应该有像@Before这样的建议或切入点注释.它需要是@Component,以便Spring知道扫描它.
