为什么抛出异常时我的方面代码无法运行？

Question

In my spring project I've added two dependencies:

<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjrt</artifactId>
    <version>1.9.2</version>
</dependency>
<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjweaver</artifactId>
    <version>1.9.2</version>
</dependency>

and then I've created a class:

package com.my.company.package.handling;

@Aspect
public class MyAspect {
@AfterThrowing(pointcut = "execution(* com.my.company.package.*(..))", throwing = "ex")
    public void logAfterThrowing(Exception ex) {
        System.out.println("exception "+ex.getLocalizedMessage())
    }
}

Now in some other class (stored in package: com.my.company.package.someOtherPackage ) I'm throwing exception:

throw new IOException("here comes error");

but then I don't see the printout from my aspect method in the console. What am I missing here?

Answer 1

Assuming everything else is correct you need a @Component annotation also, you also need another * in the execution string for any class.

@Aspect
@Component
public class MyAspect {
@AfterThrowing(pointcut = "execution(* com.my.company.package.*.*(..))", throwing = "ex")
    public void logAfterThrowing(Exception ex) {
        System.out.println("exception "+ex.getLocalizedMessage())
    }
}

Here's a working example
