@Aspect
@Component
public class JsonAspect {

    @Before("execution(public * au.com.mycompany.web.controllers.DummyController.dummy(..))")
    public final void beforeMethod1(final JoinPoint joinPoint) {
        System.out.println("Intercepted.............");
        System.out.println(joinPoint.getSignature().getName());
    }

}

控制器IMPL

@Controller
public interface DummyController {

    @RequestMapping(value = "/dummy", method = RequestMethod.GET)
    @ResponseBody
    String dummy();

}

---

我假设这不再相关，但我遇到了完全相同的问题，解决方案是在应用程序上下文中设置这一点：

@Controller
public class DummyControllerImpl implements DummyController {

    @Override
    public final String dummy() {
        System.out.println("IT WORKED..........");
        return "it returned";
    }
}

根本原因是，为此类生成的AOP自动代理是JdkAutoProxy而不是CGLIB生成的代理-这导致API的spring MVC调用失败，因为代理与控制器的类型不同。

---

之所以使用此JdkAutoProxy，是因为此特定控制器实现了一个接口，这会导致spring自动使用JDK自动代理。

尝试从参数部分“执行（public*au.com.mycompany.web.controllers.DummyController.dummy（..）”->执行中删除“..”（public*au.com.mycompany.web.controllers.DummyController.dummy（））这不起作用，仍然会收到相同的错误。

@Controller
public interface DummyController {

    @RequestMapping(value = "/dummy", method = RequestMethod.GET)
    @ResponseBody
    String dummy();

}

@Controller
public class DummyControllerImpl implements DummyController {

    @Override
    public final String dummy() {
        System.out.println("IT WORKED..........");
        return "it returned";
    }
}
