讓客戶滿意是我們工作的目標(biāo)，不斷超越客戶的期望值來(lái)自于我們對(duì)這個(gè)行業(yè)的熱愛(ài)。我們立志把好的技術(shù)通過(guò)有效、簡(jiǎn)單的方式提供給客戶，將通過(guò)不懈努力成為客戶在信息化領(lǐng)域值得信任、有價(jià)值的長(zhǎng)期合作伙伴，公司提供的服務(wù)項(xiàng)目有：國(guó)際域名空間、虛擬空間、營(yíng)銷(xiāo)軟件、網(wǎng)站建設(shè)、東蘭網(wǎng)站維護(hù)、網(wǎng)站推廣。

在項(xiàng)目中引入springcloud中的gateway時(shí)報(bào)以下錯(cuò)誤

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.

這個(gè)是由于依賴沖突，spring-cloud-starter-gateway與spring-boot-starter-web和spring-boot-starter-webflux依賴沖突

解決方式：

在引入gateway時(shí)過(guò)濾掉上面兩個(gè)依賴

 
            org.springframework.cloud
            spring-cloud-starter-gateway
            
                
                    org.springframework.boot
                    spring-boot-starter-web
                
                
                    org.springframework.boot
                    spring-boot-starter-webflux

問(wèn)題：

springboot整合gateway啟動(dòng)失敗

這塊主要是版本兼容的問(wèn)題，

最初用的版本是：

            io.projectreactor.netty
            reactor-netty
            0.9.4.RELEASE
        

網(wǎng)上有的是需要把這個(gè)版本降低，我這是降低了也不行

最后升高了版本改成了：

            io.projectreactor.netty
            reactor-netty
            0.9.14.RELEASE
        

本項(xiàng)目里springboot版本為：2.3.1，根據(jù)自己項(xiàng)目需要吧，看一下自己項(xiàng)目中各個(gè)版本之間的問(wèn)題
