我在spring aop（spring version 5.1.3.RELEASE）中编写了简单的自定义注释。
然后我在我的处理程序拦截器类中使用它。
@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----------");
}
}
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
}
}
@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();
}
}
当我运行应用程序时，它给出了以下错误。
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].

但是当我在拦截器类中评论@Test时工作正常。
是否有人可以描述它为什么会发生以及如何解决这个问题将会非常有帮助。提前致谢。
消息：@Bean方法MainConfiguration.checkAccessInterceptor被调用为类型[com.epic.edbs.ib_rest.interceptor.CheckAccessInterceptor]的bean引用，但被类型为[com.sun.proxy。$ Proxy117]的非兼容bean实例覆盖
我厌倦了springboot，但我没有发现你的错误。我想以下可以帮助你。将aop方式更改为除JDK代理之外的CGLIB
@EnableAspectJAutoProxy(proxyTargetClass = true)
@EnableWebMvc
@EnableCaching
@Configuration
@ComponentScan(basePackages = { "com.example.boot" })
public class MainConfiguration {
