博客内容讲述了在使用SpringCloudGateway时遇到的启动失败问题，原因是spring-cloud-starter-gateway与spring-boot-starter-web存在冲突。解决方案是排除这两个依赖。通过在pom.xml文件中对spring-cloud-starter-gateway的依赖进行排除操作，可以避免冲突，从而成功启动应用。

SpringCloud Gateway

原因：spring-cloud-starter-gateway 与 spring-boot-starter-web 冲突

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>

修改为下面：

    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-gateway</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
