  • springcloud zookeeper+gateway

    搭建springcloud项目的时候以 zookeeper为注册中心  gateway为路由 启动时出现以下报错:

    **********************************************************

    Spring MVC found on classpath, which is incompatible with Spring Cloud Gateway at this time. Please remove spring-boot-starter-web dependency.

    **********************************************************

    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.

    原因:

      在类路径上找到了SpringMVC,此时它与SpringCloudGateway不兼容。请删除Spring Boot Starter Web依赖项。

      然后看pom.xml里面并没有依赖SpringMVC相关依赖,然而是zookeeper里面依赖了web,SpringCloudGateway依赖于webflux 所以不兼容
