Question

我正在从链接 https://github.com/saurzcode/saurzcode-swagger-spring/ 开发 Spring Boot + Swagger 实施。在这个项目中，我只是将'swagger-springmvc' maven依赖项更新为其最新版本。当我这样做时，我开始面对以下错误。请指导我们如何解决这个问题。

Answer 1

只有我在import ApiInfo语句中看到问题。在Spring Swagger版本1.0.2中，ApiInfo是com.mangofactory.swagger.models.dto的一个类，而不是来自import com.wordnik.swagger.model.ApiInfo的类;这将解决您的问题。这是输出：

java.lang.IllegalStateException：由于找不到内部类，无法评估条件。 - Spring Boot + Spring Swagger
