看起来您的 servlet 容器没有启动。请尝试添加此 maven 依赖项&nbsp; &nbsp; <dependency>&nbsp; &nbsp; &nbsp; &nbsp; <groupId>org.springframework.boot</groupId>&nbsp; &nbsp; &nbsp; &nbsp; <artifactId>spring-boot-starter-web</artifactId>&nbsp; &nbsp; </dependency>您可以删除这些依赖项：&nbsp;<dependency>&nbsp; &nbsp; <groupId>org.springframework</groupId>&nbsp; &nbsp; <artifactId>spring-web</artifactId>&nbsp;</dependency>&nbsp;<dependency>&nbsp; &nbsp; <groupId>org.springframework.boot</groupId>&nbsp; &nbsp; <artifactId>spring-boot-starter</artifactId>&nbsp;</dependency>它们由建议的启动器提供。
