Пользовательская аннотация Spring Aop выдает ошибку в классе перехватчика Handler

0 голосов
/ 03 апреля 2019

Я написал простую пользовательскую аннотацию в Spring Aop (весенняя версия 5.1.3.RELEASE).

Затем я использую ее в своем классе перехватчика обработчика.

Пользовательская аннотация. 

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface Test {}

@Aspect
@Component
public class TestAspect {

    @Before(value = "@annotation(Test)")
    public void beforeInterceptorLog(JoinPoint joinPoint){
        System.out.println("---------test before----------");
    }

    @After(value = "@annotation(Test)")
    public void afterInterceptorLog(JoinPoint joinPoint){
        System.out.println("---------test after----------");
    }
}

Класс перехватчика. 

public class CheckAccessInterceptor implements HandlerInterceptor {
    @Test
    @Override
    public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception {
        return true;
    }

    @Test
    @Override
    public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {
        //TODO
    }
}

Конфигурация пружины 

@EnableAspectJAutoProxy
@EnableWebMvc
@EnableCaching
@EnableTransactionManagement
@Configuration
@ComponentScan(basePackages = { "com.epic.*" })
public class MainConfiguration{
    @Bean
    public WebMvcConfigurerAdapter adapter() {
        return new WebMvcConfigurerAdapter() {
            @Override
            public void addInterceptors(InterceptorRegistry registry) {
                registry.addInterceptor(checkAccessInterceptor()).addPathPatterns("/api/v1/**");
            }
        };
    }

    @Bean
    public CheckAccessInterceptor checkAccessInterceptor() {
        return new CheckAccessInterceptor();
    }
}

При запуске приложения выдается сообщение об ошибке ниже. 

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerMapping' defined in org.springframework.web.servlet.config.annotation.DelegatingWebMvcConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping]: Factory method 'requestMappingHandlerMapping' threw exception; nested exception is java.lang.IllegalStateException: @Bean method MainConfiguration.checkAccessInterceptor called as bean reference for type [com.epic.edbs.ib_rest.interceptor.CheckAccessInterceptor] but overridden by non-compatible bean instance of type [com.sun.proxy.$Proxy117].

Но когда я комментирую @Test в классе перехватчика, он работает нормально.

Кто-нибудь может описать, почему это произошло, и как решить эту проблему, это будет очень полезно.Заранее спасибо.

Сообщение: метод @Bean MainConfiguration.checkAccessInterceptor вызывается как ссылка на компонент для типа [com.epic.edbs.ib_rest.interceptor.CheckAccessInterceptor], но переопределяется несовместимым экземпляром компонента типа [com.sun.proxy. $ Proxy117 ]

Я устал от Springboot, но я не нашел твоей ошибки. Думаю, что ниже может помочь тебе. измените aop способ на CGLIB, отличный от прокси JDK 

@EnableAspectJAutoProxy(proxyTargetClass = true)
@EnableWebMvc
@EnableCaching
@Configuration
@ComponentScan(basePackages = { "com.example.boot" })
public class MainConfiguration {
