在项目中引入springcloud中的gateway时报以下错误
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
解决方式：
在引入gateway时过滤掉上面两个依赖
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-gateway</artifactId> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </exclusion> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-webflux</artifactId> </exclusion> </exclusions> </dependency>
springboot整合gateway启动失败问题：

这块主要是版本兼容的问题，
最初用的版本是：
<dependency> <groupId>io.projectreactor.netty</groupId> <artifactId>reactor-netty</artifactId> <version>0.9.4.RELEASE</version> </dependency>
网上有的是需要把这个版本降低，我这是降低了也不行
最后升高了版本改成了：
<dependency> <groupId>io.projectreactor.netty</groupId> <artifactId>reactor-netty</artifactId> <version>0.9.14.RELEASE</version> </dependency>
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
以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
