我尝试在我的Spring Boot项目中使用swagger和springdoc，不知道为什么，每次我尝试访问http：//localhost：8080/v3/api-docs时，我都会收到一个内部服务器错误，下面是我的堆栈跟踪：https://pastebin.com/y2W5t8He

你能帮帮我吗？
我试过重新启动，重新加载我的依赖项，并检查不同的依赖项。

我可以通过向所有使用JpaRepository实现的存储库方法添加@Param注解来修复（变通方案）该错误，例如：
Optional<File> findByFileType(@Param("fileType") String fileType);
当方法没有任何@Param时，我得到500错误，当我向所有存储库中的所有方法添加注解时，现在Swagger正确加载。
经过更多的测试，似乎这个问题只出现在我的存储库中仅有的两个参数的方法中，所以我只需要将@Param添加到我所有存储库中的一个方法中：
Optional<Dictionary> findByDictionaryNameAndDictionaryValue( @Param("dictionaryName") String dictionaryName, @Param("dictionaryValue") String dictionaryValue);
在我的例子中，这个存储库和其他存储库中的第二个方法不需要@Param注解。
