spring boot3报错Cannot invoke PatternsRequestCondition.getPatterns()“ because “this.condition“ is null

解决方法。在启动类Application里添加一个bean,即可

@Bean
	public BeanPostProcessor springfoxHandlerProviderBeanPostProcessor() {
		return new BeanPostProcessor() {


			@Override
			public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
				if (bean instanceof WebMvcRequestHandlerProvider || bean instanceof WebFluxRequestHandlerProvider) {
					customizeSpringfoxHandlerMappings(getHandlerMappings(bean));
				}
				return bean;
			}


			private <T extends RequestMappingInfoHandlerMapping> void customizeSpringfoxHandlerMappings(List<T> mappings) {
				List<T> copy = mappings.stream().filter(mapping -> mapping.getPatternParser() == null).collect(Collectors.toList());
				mappings.clear();
				mappings.addAll(copy);
			}


			@SuppressWarnings("unchecked")
			private List<RequestMappingInfoHandlerMapping> getHandlerMappings(Object bean) {
				try {
					Field field = ReflectionUtils.findField(bean.getClass(), "handlerMappings");
					field.setAccessible(true);
					return (List<RequestMappingInfoHandlerMapping>) field.get(bean);
				} catch (IllegalArgumentException | IllegalAccessException e) {
					throw new IllegalStateException(e);
				}
			}
		};
	}
