spring-boot - Spring Boot 应用程序中不匹配的托管依赖项导致类路径版本问题

Question

我有一个 Spring Boot 应用程序，版本 2.1.7，它引入了 spring-boot-webmvc-5.1.9.RELEASE。maven构建一切都很好。但是，当我尝试启动 spring boot 应用程序时，它会抱怨说：

Correct the classpath of your application so that it contains a single, compatible version of 
org.springframework.boot.autoconfigure.web.servlet.WebMvcAutoConfiguration$EnableWebMvcConfiguration

我的依赖树如下所示：
