拦截器报循环依赖错误

拦截器

@Slf4j
@Component
public class LcOpPermissionInterceptor extends HandlerInterceptorAdapter {

    ......

}

将拦截器注入适配器中

@Configuration
public class LcOpWebMvcConfigurer  extends WebMvcConfigurerAdapter {

    @Autowired
    private LcOpPermissionInterceptor lcOpPermissionInterceptor;

这样写有的时候会导致循环依赖问题，需要换一种写法。去掉上面的@Component注解，改用下面@Bean来注入Bean

@Configuration
public class LcOpWebMvcConfigurer  extends WebMvcConfigurerAdapter {

    @Bean
    public LcOpPermissionInterceptor lcOpPermissionInterceptor(){
        return new LcOpPermissionInterceptor() ;
    }
