网关项目启动报错内容如下：

Description:

Parameter 0 of method modifyRequestBodyGatewayFilterFactory in org.springframework.cloud.gateway.config.GatewayAutoConfiguration required a bean of type 'org.springframework.http.codec.ServerCodecConfigurer' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.http.codec.ServerCodecConfigurer' in your configuration.

Process finished with exit code 1

主要原因其实就是在我把公共包core放在了gateway中，导致启动出现问题，经排查发现是spring-cloud-starter-gateway和spring-boot-starter-web之间的冲突
发现根本原因后就好说了，直接排除Core包中的spring-boot-starter-web就可以了这里请注意的是不是让你去修改core包中的pom文件，是修改gateway项目中的pom文件进行排除。具体代码如下：
