无法启动由swagger生成的springboot服务器

Question

我是新来的swagger，我必须为给定的POJO(只是POJO)编写swagger并为其实现API。因此，通过使用swagger编辑器，我能够编写没有错误的swagger处理程序，然后执行1. 从菜单和选定的弹簧生成服务器2. 从菜单和选定的客户端生成客户端

我打开生成的java API客户端并成功构建。我打开IntelliJ中生成的spring服务器并尝试运行服务器，我得到以下错误…

我尝试为他们提供的示例default, heroku, instagram, twitter生成spring服务器，并且对于这些也得到相同的错误。

Answer 1

我认为问题是tomcat的provided范围。这将假设您将应用程序部署到现有的tomcat实例中。您可以尝试删除该范围、刷新项目并再次运行吗?
