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 = "

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

";
 
 @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>
    </dependencyManagement>
