Spring Boot & Spring Cloud & Nacos 版本搭配

一个有效的 Spring Boot & Spring Cloud & Spring Cloud Alibaba Nacos 搭配

Spring Boot内嵌tomcat, 是通过其父pom文件中引入相关依赖实现的，但有时候父pom文件中的依赖并不生效，需要手动引入tomcat依赖项实现：

<dependency>
	<groupId>org.apache.tomcat.embedgroupId>
	<artifactId>tomcat-embed-coreartifactId>
	<version>9.0.62version>
dependency>

否则引入如下类时会报错：

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
