解决Spring Boot 6.x 与Swagger 3.0.0 不兼容问题

报错如下：Failed to start bean 'documentationPluginsBootstrapper'; nested exception is java.lang.NullPointerException

解决方案1：

如果项目中没引入

org.springframework.boot

spring-boot-starter-actuator

则直接在yml文件中加入如下配置即可，如果引入了这个jar包，则参考解决方案2

spring:
  mvc:
    pathmatch:
      matching-strategy: ANT_PATH_MATCHER

解决方案2：

yml文件中增加配置

spring:
  mvc:
    pathmatch:
      matching-strategy: ANT_PATH_MATCHER

然后再增加这么一段代码即可

    /**
     * 增加如下配置可解决Spring Boot 6.x 与Swagger 3.0.0 不兼容问题
     **/
    @Bean
    public WebMvcEndpointHandlerMapping webEndpointServletHandlerMapping(WebEndpointsSupplier webEndpointsSupplier, ServletEndpointsSupplier servletEndpointsSupplier, ControllerEndpointsSupplier controllerEndpointsSupplier, EndpointMediaTypes endpointMediaTypes, CorsEndpointProperties corsProperties, WebEndpointProperties webEndpointProperties, Environment environment) {
        List> allEndpoints = new ArrayList();
        Collection webEndpoints = webEndpointsSupplier.getEndpoints();
        allEndpoints.addAll(webEndpoints);
        allEndpoints.addAll(servletEndpointsSupplier.getEndpoints());
        allEndpoints.addAll(controllerEndpointsSupplier.getEndpoints());
        String basePath = webEndpointProperties.getBasePath();
        EndpointMapping endpointMapping = new EndpointMapping(basePath);
        boolean shouldRegisterLinksMapping = this.shouldRegisterLinksMapping(webEndpointProperties, environment, basePath);
        return new WebMvcEndpointHandlerMapping(endpointMapping, webEndpoints, endpointMediaTypes, corsProperties.toCorsConfiguration(), new EndpointLinksResolver(allEndpoints, basePath), shouldRegisterLinksMapping, null);
    }
    private boolean shouldRegisterLinksMapping(WebEndpointProperties webEndpointProperties, Environment environment, String basePath) {
        return webEndpointProperties.getDiscovery().isEnabled() && (StringUtils.hasText(basePath) || ManagementPortType.get(environment).equals(ManagementPortType.DIFFERENT));
    }
