java - 如何使用 springdoc-openapi-starter-webmvc-ui :2. 0.2 在 Spring Boot 中访问/v3/api-docs 时修复 http 500 错误？

Question

我正在尝试在我的小型 Spring Boot 项目中使用 swagger 和 springdoc。我不知道为什么，但每次我尝试访问 http://localhost:8080/v3/api-docs 时，都会收到内部服务器错误。这是我的堆栈跟踪:https://pastebin.com/y2W5t8He

你能帮我吗？

我尝试过重新启动、重新加载我的依赖项并检查不同的依赖项。

Answer 1

我能够通过向使用 JpaRepository 实现的所有存储库方法添加 @Param 注释来修复(解决方法)该错误，例如:

Optional<File> findByFileType(@Param("fileType") String fileType);

当该方法没有任何 @Param 时，我收到 500 错误，当我将注释添加到所有存储库中的所有方法时，现在 Swagger 可以正确加载。

编辑。经过更多测试后，在我的情况下，问题似乎仅出现在我的存储库中只有 2 个参数方法，因此我只需将 @Param 添加到我所有存储库中的一个方法:

Optional<Dictionary> findByDictionaryNameAndDictionaryValue( @Param("dictionaryName") String dictionaryName, @Param("dictionaryValue") String dictionaryValue);

在我的例子中，此存储库和其他存储库中的第二种方法不需要@Param注释。
