2. 查找原因

网上搜索了各种办法，包括clone别人的代码，感觉明明一模一样的，为什么别人就可以，自己的就不行。直到看到了某篇博客的描述：

感觉我瞬间好像会了，没错，就是版本兼容问题，说干就干

2.1 此前笔者的代码

spring boot版本为3+

swagger版本为2+

3. 问题解决说明

swagger 2.0版本和spring boot 3.x版本整合暂时是不行的，因为swagger的依赖底层用的是javax依赖包，而spring boot 3.x版本都是jakarta依赖包，一般是把spring boot2.5以下就可以了，但是想要2.5版本以上spring boot启动就会出报错
因此这里不能再使用springfox，得换成别的，比如笔者使用的springdoc

4. 解决方案

4.1 在pom.xml引入springdoc包

这里面已经包含了swagger，不用担心如何引入swagger

        <!-- 生成接口文档 -->
        <dependency>
            <groupId>org.springdoc</groupId>
            <artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
            <version>2.0.2</version>
        </dependency>
        <dependency>
            <groupId>org.springdoc</groupId>
            <artifactId>springdoc-openapi-starter-webmvc-api</artifactId>
            <version>2.0.2</version>
        </dependency>

4.2 创建配置文件（可省略）

在config文件夹下创建SpringDocConfig.java，添加以下代码

@Configuration
@OpenAPIDefinition(info = @Info(title = "数据标签管理系统", description = "数据标签管理", version = "1.0"))
@SecurityScheme(name = "token", type = SecuritySchemeType.HTTP, bearerFormat = "JWT", scheme = "bearer")
public class SpringDocConfig {
}

4.3 在controller加入注解

4.4 查看接口文档

在地址栏输入http://localhost:9090/swagger-ui/index.html#/

ip和端口自行修改，之后可看到界面，代表swagger配置成功
