springboot注冊到consul中報錯：Spring MVC found on classpath, which is incompatible with Spring Cloud

今天在做springboot整合成springCloud并注冊到consul中時，發現若注冊到consule中成功 則不能啟動swagger，且不能提供任何API服務，要是能提供API服務則不能注冊到consule中，并報錯“

 
 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，發現在如下代碼中會報這個log資訊

 
 @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);       
          
 }       
          
 }       
          
 }       
     
         

最終，我們分析是swagger啟動時所要的jar包和springCloud有所沖突，修改我們的POM檔案如下，主要是版本的問題：

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