Swagger加入拦截器后swagger-ui.html不显示

我是这样解决的：

在拦截器里面加入request.getRequestURI()，先打个断点看看请求的资源路径，然后根据这些路径加入到excludePathPatterns里面。下面是我的代码

@Component
    @CrossOrigin(origins = "*", maxAge = 3600)
    public class AccessInterceptor implements HandlerInterceptor {
        @Override
        public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
            String url = request.getRequestURI();//这里打端点，页面访问swagger页面看看请求的什么路径
             
            return true;
        }
    
        @Override
        public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
    
        }
    
        @Override
        public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
    
        }
    }

然后在excludePathPatterns里面加入查看到的路径

@Configuration
    public class CustomWebMvcConfigurerAdapter implements WebMvcConfigurer {
        @Override
        public void addInterceptors(InterceptorRegistry registry) {
            /**
             *此处拦截路径（/**）
             * 注意两个**。一个*号只拦截一级路径下，两个*号拦截所有
             */
            registry.addInterceptor(new UserInterceptor()).addPathPatterns("/**")
                    .excludePathPatterns("/rest/login.do/info")
                    .excludePathPatterns("/swagger-resources/**", "/webjars/**", "/v2/**", "/swagger-ui.html/**");
        }
        @Override
        public void addResourceHandlers(ResourceHandlerRegistry registry) {
            //将templates目录下的CSS、JS文件映射为静态资源，防止Spring把这些资源识别成thymeleaf模版
            registry.addResourceHandler("/templates/**.js").addResourceLocations("classpath:/templates/");
            registry.addResourceHandler("/templates/**.css").addResourceLocations("classpath:/templates/");
            //其他静态资源
            registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
            //swagger增加url映射
            registry.addResourceHandler("swagger-ui.html")
                    .addResourceLocations("classpath:/META-INF/resources/");
            registry.addResourceHandler("/webjars/**")
                    .addResourceLocations("classpath:/META-INF/resources/webjars/");
        }
    }

最后完美解决
