查找原因

在网上根据这个报错搜索了一番,各种答案都和我这个好像没有关系,而且他们的解答好像都是复制了,都没说明原因

那就只能自己想办法解决,报错解释:不支持具有相同组名的多个文档。发现以下重复组。default

完全没有头绪,default ,然后mvn pakcage -X 打包查询也是相同的错误,没有更详细的原因,

问题点

根据报错提供的 documentationPluginsBootstrapper 和 DefaultLifecycleProcessor.doStart(DefaultLifecycleProcessor.java:185) 和 报错打印

找到 DefaultLifecycleProcessor 中抛出异常的地方,找到

  1. DocumentationPluginsBootstrapper.start() 方法报错,debug ,找出更深层的报错 在 DocumentationPluginsManager.documentationPlugins()

最后发现是有两个 Swagger 文档的配置类,然后去掉其中一个就恢复正常了
