【SpringBoot报错】org.springframework.context.ApplicationContextException: Failed to start bean ‘documen

报错信息：org.springframework.context.ApplicationContextException: Failed to start bean 'documentationPluginsBootstrapper'; nested exception is java.lang.NullPointerException

原因：springboot2.6.x版本与swagger2版本不兼容

解决方法：

在application.yml中配置

spring:
  mvc:
    pathmatch:
      matching-strategy: ant-path-matcher #2.6版本Spring MVC 处理映射匹配的默认策略已从AntPathMatcher更改为PathPatternParser
      

或在application.properties中配置

# 处理SpringBoot2.6.x与Swagger2 版本冲突
spring.mvc.pathmatch.matching-strategy=ant_path_matcher
