springboot:2.7.2 整合swagger3.X 1启动失败： org.springframework.context.ApplicationContextException: Failed to start bean 'documentationPluginsBootstrapper'; nested exception is java.lang.NullPointerException 在swagger 配置类中添加 @Bean public static BeanPostProcessor springfoxHandlerProviderBeanPostProcessor() { return new BeanPostProcessor() {

2 swagger接口没显示的问题
在yml 文件配置
spring:
mvc:
pathmatch:
matching-strategy: ant_path_matcher
