今天在做springboot整合成springCloud并注册到consul中时，发现若注册到consule中成功 则不能启动swagger，且不能提供任何API服务，要是能提供API服务则不能注册到consule中，并报错“

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

”

分析了一下，发现在如下代码中会报这个log信息

@Configuration
    
    @AutoConfigureBefore(GatewayAutoConfiguration.class)
    
    public class GatewayClassPathWarningAutoConfiguration {
    
     private static final Log log = LogFactory.getLog(GatewayClassPathWarningAutoConfiguration.class);
    
     private static final String BORDER = "\n\n**********************************************************\n\n";
    
     @Configuration
    
     @ConditionalOnClass(name = "org.springframework.web.servlet.DispatcherServlet")
    
     protected static class SpringMvcFoundOnClasspathConfiguration {
    
      public SpringMvcFoundOnClasspathConfiguration() {
    
       log.warn(BORDER+"Spring MVC found on classpath, which is incompatible with Spring Cloud Gateway at this time. "+
    
         "Please remove spring-boot-starter-web dependency."+BORDER);
    
      }
    
     }
    
     @Configuration
    
     @ConditionalOnMissingClass("org.springframework.web.reactive.DispatcherHandler")
    
     protected static class WebfluxMissingFromClasspathConfiguration {
    
      public WebfluxMissingFromClasspathConfiguration() {
    
       log.warn(BORDER+"Spring Webflux is missing from the classpath, which is required for Spring Cloud Gateway at this time. "+
    
         "Please add spring-boot-starter-webflux dependency."+BORDER);
    
      }
    
     }
    
    }

最终，我们分析是swagger启动时所要的jar包和springCloud有所冲突，修改我们的POM文件如下，主要是版本的问题：

发现consul 1.2版本需要和SpringCloud的Finchley版本才能整合
