非常简单的Spring AOP切入点

Question

package com.baz;

@Aspect
public class ServiceAspect {
   @Pointcut("execution(* com.foo.ServiceImpl.create(..))")
    public void create() {}

    @Pointcut("execution(* com.bar.Subscription.setStatus(..))")
    public void setStatus() {}

    // works
    @AfterReturning(pointcut="create()", returning="retVal")
    public void afterCreate(Object retVal) {
        // omitted
    }

    // doesn't work
    @Before("setStatus()")
    public void status() {
        // omitted
    }

    // doesn't work
    @Before("setStatus() && args(status)")
    public void status(int status) {
        // omitted
    }

    // doesn't work
    @After("setStatus()")
    public void status() {
        // omitted
    }

    // doesn't work
    @AfterReturning(pointcut="setStatus()")
    public void status2() {
        // omitted
    }

    // doesn't work
    @AfterReturning(pointcut="setStatus()", returning="retVal")
    public void afterSetStatus(Object retVal) {
        // omitted
    }

    // doesn't work
    @Around("setStatus()")
    public Object aroundStatus(ProceedingJoinPoint pjp) throws Throwable {
        Object output = pjp.proceed();
        return output;
    }
}

这些方法如下所示：

public class Subscription extends FooBar implements Baz {
    public void setStatus(int status) { /* ... */ }
}

public class ServiceImpl implements Service {
    public Subscription create(Session session, Subscription template) { /* ... */ }
}

编辑

我尝试使用 、 和 。

我曾尝试直接在订阅上调用setstatus()，但它也没有捕捉到这一点。

Subscription subscription = new Subscription();
subscription.setStatus(1);

Answer 1

认购认购=新认购（）；

Subscription.SetStatus(1)；

订阅应该是要应用的方面的Spring管理bean，即您应该从applicationcontext中获得Subscription类型的对象，如下所示：

ClassPathXmlApplicationContext context = 
    new ClassPathXmlApplicationContext("classpath:META-INF/Spring.xml");
Subscription subscription = context.getBean(Subscription.class);
