java - 使用 springfox-swagger2 版本 3.0.0-SNAPSHOT 观察错误 "Unable to infer base url"

Question

我正在使用 spring-boot 2.1.6.RELEASE 以及 springfox-swagger2 版本 3.0.0-SNAPSHOT。但无法启动 swagger-ui (即 http://localhost:808/swagger-ui.html )或 api-docs (即 http://localhost:8080/v2/api-docs )url。

相同的配置适用于 springfox-swagger2 版本 2.9.2。唯一的区别是添加了 @EnableSwagger2WebMvc 和 3.0.0-SNAPSHOT。

Spring Boot应用

我不确定在使用 springfox-swagger2 版本 3.0.0-SNAPSHOT 时缺少什么。我根本没有启用任何安全性。我想使用普通的 spring-web 和 swagger。非常感谢任何解决此问题的指示。

将缺少的依赖项添加到 pom.xml 后问题已解决

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-spring-webmvc</artifactId>
    <version>3.0.0-SNAPSHOT</version>
</dependency>
