知道如何解决这个问题吗？

找到了解决方案

在我的pom.xml中有两个依赖项，如

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
</dependency>

<dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>5.2.8.RELEASE</version>
</dependency>


org.springframework.boot
SpringBootStarterWeb
org.springframework
弹簧网
5.2.8.1发布

我所做的是删除SpringWeb的依赖项，重新加载所有Maven插件，并再次尝试运行该项目

是的
