Error creating bean with name 'createSpringFoxRestApi' defined in class path resource [com/spring4all/swagger/DocketConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [void]: Factory method 'createSpringFoxRestApi' threw exception; nested exception is java.lang.NullPointerException: Cannot invoke "java.util.List.stream()" because "properties" is null

报的错一模一样

有 Demo 工程或者其他么?我可以验证定位一下。

工程就是简单的spring项目,然后pom.xml里面增加配置:
<dependency>
<groupId>com.spring4all</groupId>
<artifactId>swagger-spring-boot-starter</artifactId>
<version>2.0.1.RELEASE</version>
</dependency>

在application.yaml里面增加配置:
springfox:
documentation:
enabled: true
swagger:
base-package: 'com.example'
base-path: '/**'
title: '注解方式的Swagger'
description: '这是注解方式的Swagger'
version: '2.0.1.RELEASE'

其他没有增加配置,在运行项目的时候就会报出这个错误;还有,在使用低一点的版本的时候使用和demo一样的配置也会报出不同的错误,但是也是启动不了项目,暂时还不清楚是哪里出了问题。
使用的java-16,编辑器是VScode,spring boot版本最新刚配置的

建议你查看一下spring boot 的版本,如果是2.6.0-M3,可以改成2.6.0-M2试一下

和我报的错一样,从2.0.1.RELEASE降低至1.9.1.RELEASE就正常了,环境是springboot 2.5.6,flowable 6.7.0

我看了下,确实是缺少了部分全局配置导致的,主要是:globalOperationParameters的全局配置

复现版本:
