It was loaded from the following location:


    file:/C:/Users/Shinelon/.m2/repository/org/springframework/spring-web/5.2.2.RELEASE/spring-web-5.2.2.RELEASE.jar




Action:


Correct the classpath of your application so that it contains a single, compatible version of org.springframework.web.accept.ContentNegotiati

添加spring-web

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>5.2.4.RELEASE</version>
</dependency>

注意如果存在spring-webmvc，那么保持版本号一致
