springboot注册到consul中报错：Spring MVC found on classpath, which is incompatible with Spring Cloud

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

<parent>





        <groupId>org.springframework.boot</groupId>





        <artifactId>spring-boot-starter-parent</artifactId>





        <version>2.0.3.RELEASE</version>





        <relativePath/> <!-- lookup parent from repository -->





    </parent>





 





 





 





 





 





    <dependencyManagement>





        <dependencies>





            <dependency>





                <groupId>org.springframework.cloud</groupId>





                <artifactId>spring-cloud-dependencies</artifactId>





                <version>Finchley.RELEASE</version>





                <type>pom</type>





                <scope>import</scope>





            </dependency>





        </dependencies>
