## 1.还是和SpringCloud  Config配置中心动态刷新配置文件一样   ##

了解配置中心 [https://blog.csdn.net/zhangshengqiang168/article/details/104465721][https_blog.csdn.net_zhangshengqiang168_article_details_104465721]

## 2.在码云创建一个新的配置文件 **zuul-gateway-dynamic-dev.properties .**内容为zuul网关配置信息 ##

## 3.搭建动态zuul网关项目(这里需要之前config-server 配置中心服务端服务) ##

###    1.添加pom.xml依赖 ###

<dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
            </dependency>
            
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-config-client</artifactId>
            </dependency>
            
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-actuator</artifactId>
            </dependency>
             
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            </dependency>

### 2.application.properties配置文件 ###

#指定运行端口
    server.port=80
    
    #配置注册中心地址
    eureka.client.service-url.defaultZone=http://localhost:8000/eureka/
    
    #配置连接配置中心码云读取配置文件信息
    #服务名称 码云配置文件zuul-gateway-dynamic-dev.properties 的项目名称 zuul-gateway-dynamic
    spring.application.name=zuul-gateway-dynamic
    
    #读取版本环境 码云配置文件zuul-gateway-dynamic-dev.properties 的环境 dev
    spring.cloud.config.profile=dev
    
    #读取config-server环境  读取的配置中心名称
    spring.cloud.config.discovery.service-id=config-server
    
    #开启读取权限
    spring.cloud.config.discovery.enabled=true
    
    #监控中心开启所有端点
    management.endpoints.web.exposure.include=*

### 3.启动类 ###

@SpringBootApplication
    @EnableEurekaClient
    @EnableZuulProxy   //开启zuul 网关
    public class AppGateWayDynamic {
        public static void main(String[] args) {
            SpringApplication.run(AppGateWayDynamic.class,args);
        }
    
        //zuul配置能够使用config实现实时更新
        @RefreshScope
        @ConfigurationProperties("zuul")
        public ZuulProperties zuulProperties(){
            return new ZuulProperties();
        }
    }

### 4.测试 config-server 尝试访问配置文件信息[http://localhost:8888/zuul-gateway-dynamic-dev.properties][http_localhost_8888_zuul-gateway-dynamic-dev.properties] ###

###    尝试网关访问是否有效   [http://localhost/api-member?userToken=111![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYW5nc2hlbmdxaWFuZzE2OA_size_16_color_FFFFFF_t_70 1][]][http_localhost_api-member_userToken_111_watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYW5nc2hlbmdxaWFuZzE2OA_size_16_color_FFFFFF_t_70 1] ###

### 5.尝试修改码云上的[zuul-gateway-dynamic-dev.properties][http_localhost_8888_zuul-gateway-dynamic-dev.properties]配置文件,并手动刷新配置文件[http://localhost:80/actuator/refresh][http_localhost_80_actuator_refresh] 访问测试 ###

### 6.可以看到之前的member已经访问不到,只能访问修改后的zhang ###
