#### 介绍 ####

springcloud gateway+nacos 实现动态路由 demo,参考了网上一些文章 博客,然后调试完成

#### 软件架构 ####

软件架构说明  
首先参考nacos官方文档,安装nacos的server服务

#### nacos 配置截图 ####

#### 一. gateway-server.yml配置 ####

spring:
      cloud:
        nacos:
          discovery:
            server-addr: ${spring.cloud.nacos.config.server-addr}
          locator:
              enabled: true
              lowerCaseServiceId: true
    
            
    nacos:
      dataId: gateway_config_json
      group: refresh_config_json
    
    server:
      port: 5008
    
    # 配置输出日志
    logging:
      level:
        org.springframework.cloud.gateway: TRACE
        org.springframework.http.server.reactive: DEBUG
        org.springframework.web.reactive: DEBUG
        reactor.ipc.netty: DEBUG
    
    #开启端点
    management:
      endpoints:
        web:
          exposure:
            include: '*'
      security:
        enabled: false

#### 二. gateway\_config\_json, 这是动态路由规则配置,注意，这里是json格式的,详细可看项目中的代码 ####

[{
        "filters": [{
             "args": {
                "parts": "1"
            },
            "name": "StripPrefix"
        }],
        "id": "hello-service",
        "order": 0,
        "predicates": [{
            "args": {
                "pattern": "/hello-service/**"
            },
            "name": "Path"
        }],
        "uri": "lb://hello-service"
    },{
        "filters": [{
             "args": {
                "parts": "1"
            },
            "name": "StripPrefix"
        }],
        "id": "eat-service",
        "order": 0,
        "predicates": [{
            "args": {
                "pattern": "/eat-service/**"
            },
            "name": "Path"
        }],
        "uri": "lb://eat-service"
    }]

#### 三.启动测试 ####

这里启动之后，项目中会有对nacos配置的监听,每次更新路由配置后,会动态的刷新到项目中

#### 四.项目地址 ,talk is cheap,show me the code,直接上代码 ####
