What does "@EnableAspectJAutoProxy" Annotation do in a Java Spring Container Configuration Class?
user
the @enableaspectjautoproxy annotation is used to enable aspectj autoproxying in a java spring container configuration class. this annotation tells spring to create proxy objects for all of the beans in the application that are annotated with @aspectj. this can be useful for applying aspects to code that is not spring-managed.

to use the @enableaspectjautoproxy annotation, you must first add the following dependency to your pom.xml file:

```
<dependency>
  <groupid>org.springframework</groupid>
  <artifactid>spring-aspects</artifactid>
  <version>${spring.version}</version>
</dependency>
```

then, you need to annotate your configuration class with @enableaspectjautoproxy:

```
@configuration
@enableaspectjautoproxy
public class appconfig {

}
```

finally, you need to add the @aspectj annotation to the classes that you want to apply aspects to. for example:

```
@aspectj
public class myaspect {

  @pointcut("execution(* com.example.*.*(..))")
  public void pointcut() {}

  @around("pointcut()")
  public object around(proceedingjoinpoint pjp) throws throwable {
    system.out.println("executing aspect");
    return pjp.proceed();
  }

}
```

when you run your application, spring will create proxy objects for all of the beans in the application that are annotated with @aspectj. these proxy objects will intercept all of the methods that are annotated with @pointcut, and will apply the aspects that are defined in those methods.
