当用了最新的swagger 2.9.2版本访问swagger首页文档会报这个错，将版本降为2.8.0就好了。

SpringBoot x整合Swagger2异常处理：解决NumberFormatException的问题
2301_79331387的博客

在SpringBoot中，我们可以使用Swagger2的注解来标记接口，然后通过访问特定的URL，就可以在浏览器中查看生成的API文档。总结起来，当在使用Swagger2进行接口测试时，遇到NumberFormatException异常，我们需要检查输入参数的类型是否与接口定义的类型相匹配。重新启动应用程序，访问Swagger2的API文档，在接口测试界面输入"abc"，点击"Execute"按钮发送请求，这次我们会得到一个带有自定义错误信息的响应结果。为了解决这个问题，我们需要对输入的参数进行类型校验。

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。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。有位作者已经写的很清楚了，此处不再赘述，，没错，就是版本兼容问题，说干就干。
