## Annotation Type EnableAspectJAutoProxy

-     @Target(value=TYPE)
      @Retention(value=RUNTIME)
      @Documented
      @Import(value=org.springframework.context.annotation.AspectJAutoProxyRegistrar.class)
      public @interface EnableAspectJAutoProxy

  Enables support for handling components marked with AspectJ's `@Aspect` annotation, similar to functionality found in Spring's `<aop:aspectj-autoproxy>` XML element. To be used on @`Configuration` classes as follows:

       @Configuration
       @EnableAspectJAutoProxy
       public class AppConfig {
           @Bean
           public FooService fooService() {
               return new FooService();
           }

           @Bean
           public MyAspect myAspect() {
               return new MyAspect();
           }
       }

  Where `FooService` is a typical POJO component and `MyAspect` is an `@Aspect`-style aspect:

       public class FooService {
           // various methods
       }

       @Aspect
       public class MyAspect {
           @Before("execution(* FooService+.*(..))")
           public void advice() {
               // advise FooService methods as appropriate
           }
       }

  In the scenario above, `@EnableAspectJAutoProxy` ensures that `MyAspect` will be properly processed and that `FooService` will be proxied mixing in the advice that it contributes.

  Users can control the type of proxy that gets created for `FooService` using the `proxyTargetClass()` attribute. The following enables CGLIB-style 'subclass' proxies as opposed to the default interface-based JDK proxy approach.

       @Configuration
       @EnableAspectJAutoProxy(proxyTargetClass=true)
       public class AppConfig {
           // ...
       }

  Note that `@Aspect` beans may be component-scanned like any other. Simply mark the aspect with both `@Aspect` and `@Component`:

       package com.foo;

       @Component
       public class FooService { ... }

       @Aspect
       @Component
       public class MyAspect { ... }

  Then use the @`ComponentScan` annotation to pick both up:

       @Configuration
       @ComponentScan("com.foo")
       @EnableAspectJAutoProxy
       public class AppConfig {
           // no explicit @Bean definitions required
       }
