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.
这个是由于依赖冲突，spring-cloud-starter-gateway与spring-boot-starter-web和spring-boot-starter-webflux依赖冲突
在引入gateway时过滤掉上面两个依赖
org.springframework.cloud spring-cloud-starter-gateway org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-webflux
springboot整合gateway启动失败

An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.springframework.cloud.gateway.config.GatewayAutoConfiguration$NettyConfiguration.gatewayHttpClient(GatewayAutoConfiguration.java:622)
The following method did not exist:
reactor.netty.resources.ConnectionProvider.elastic(Ljava/lang/String;Ljava/time/Duration;Ljava/time/Duration;)Lreactor/netty/resources/ConnectionProvider;
The method"s class, reactor.netty.resources.ConnectionProvider, is available from the following locations:

Disconnected from the target VM, address: "127.0.0.1:55875", transport: "socket"

这块主要是版本兼容的问题，
io.projectreactor.netty reactor-netty 0.9.4.RELEASE
网上有的是需要把这个版本降低，我这是降低了也不行
io.projectreactor.netty reactor-netty 0.9.14.RELEASE
本项目里springboot版本为：2.3.1，根据自己项目需要吧，看一下自己项目中各个版本之间的问题
