我已经在spring aop（5.1.3.RELEASE版本）中编写了简单的自定义注释。
然后在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，出现以下错误。
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，效果很好。
任何人都可以描述它发生的原因以及如何解决此问题，这将对您大有帮助。预先感谢。
答案 0 :(得分：1)
消息：@Bean方法MainConfiguration.checkAccessInterceptor称为[com.epic.edbs.ib_rest.interceptor.CheckAccessInterceptor]类型的bean引用，但被[com.sun.proxy。$ Proxy117类型的不兼容bean实例覆盖]
我对springboot感到厌倦，但是我没有发现您的错误。我认为以下可以为您提供帮助。 将aop方式更改为JDK代理以外的CGLIB
@EnableAspectJAutoProxy(proxyTargetClass = true)
@EnableWebMvc
@EnableCaching
@Configuration
@ComponentScan(basePackages = { "com.example.boot" })
public class MainConfiguration {
