gateway 集成 nacos 实现动态路由

gateway 集成 nacos 实现动态路由，前几篇单独分析gateway网关时，仅介绍了静态路由的原理和使用，今天我们先分析动态路由，然后介绍一下两者的区别和优缺点。

一、动态路由实战分析：

1、构建一个springboot 服务，去掉web相关的jar:

       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

加上：

       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
        </dependency>

 引入相关核心jar

artifactId>common-gateway</artifactId>
    <packaging>jar</packaging>
    <version>1.0-SNAPSHOT</version>
    <name>common-gateway</name>
    <description>网关服务</description>
    <properties>
        <java.version>1.8</java.version>
    </properties>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
        </dependency>
 
        <!-- springboot web -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
        </dependency>
 
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
        </dependency>
 
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-loadbalancer</artifactId>
        </dependency>
 
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-core</artifactId>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
        </dependency>
 
    </dependencies>

2、项目中yaml配置：

spring:
  main:
    web-application-type: reactive
  application:
    name: @project.artifactId@
    version: @project.version@
  cloud:
    nacos:
      config:
        namespace: common
        file-extension: yaml
        shared-configs:
          - data-id: common-shared-config.yaml
            group: common
            refresh: true
loggingRoot: logs

3、idea中nacos环境配置：
