java.lang.IllegalStateException: Per-clause not recognized: pmAspect

Question

I have a problem with the <aop:aspectj-autoproxy/> configuration tag.

I have added aspectjrt.jar and aspectjweaver.jar, but my setup still is not working.

<dependency>
  <groupId>org.aspectj</groupId>
  <artifactId>aspectjweaver</artifactId>
  <version>1.8.9</version>
</dependency>
<dependency>
  <groupId>org.aspectj</groupId>
  <artifactId>aspectjrt</artifactId>
  <version>1.6.1</version>
</dependency>

public class AspectTest {

  public Object around(ProceedingJoinPoint php) throws Throwable {

    return ob;

}

The way you use @Aspect("pmAspect") is obviously wrong. It seems as if you want to name the aspect,but you should do that in @Component instead, or possibly in @Bean, if for any reason in another case you want to use a factory method in your configuration class.

If you look at the @Aspect javadoc, you will notice that the value parameter is not for naming but for specifying an instantiation type, if you need something other than a singleton aspect. You cannot just put anything into a string parameter and simply assume that it will be interpreted as a name or label.

Therefore, the solution to your problem is to simply use @Aspect without any parameters.

One more thing: You do not need both AspectJ weaver and runtime in your POM. The weaver already contains the runtime. And you should upgrade to a more recent AspectJ version, not just copy and paste random snippets from the WWW. The latest version would be:

<dependency>
  <groupId>org.aspectj</groupId>
  <artifactId>aspectjweaver</artifactId>
  <version>1.9.19</version>
</dependency>

But that is not the root cause of your problem.
