@EnableAspectJAutoProxy,@Aspect and @RestController

Hi,

I use Spring-boot since few months and it’s absolutely great but I have some problems with the association @EnableAspectJAutoProx, @Aspect and @RestController.

If I declare @EnableAspectJAutoProxy and a java bean with @RestController, nothing to add, it works great.

On the other side, if I add a @Aspect with a pointcut matching the bean with @RestController, I have no more request mapping. When I looked the debug output, the logger RequestMappingHandlerMapping is quiet, the request is not performed because the mapping is not registered. For info, the bean with the @RestController is an implementation of a simple java Interface and the EnableAspectJAutoProxy use the default interface-based JDK proxy approach.

Thanks.

Your controller implements an interface and, as described in the Spring AOP documentation this means that an interface-based proxy is created. It’s this proxy that is inspected for @RequestMapping methods and none are found as there are none on the interface.

You can fix the problem by forcing the creation of class proxies:

@Configuration
@EnableAutoConfiguration
@ComponentScan
@EnableAspectJAutoProxy(proxyTargetClass=true)
public class AppConfig {

}

Hello, I uploaded a sample project, You can try it : https://github.com/scizeron/test.git. At the begining, the @Aspect is disabled, all is ok (200 OK) Afterwards, you can enable the @Aspect and you will have a 404 Not Found. Check the README for more details. Thx for all Stéphane
