SpringCloud（23）：Config：客户端连接服务端访问远程

怼烎@ 2022-10-27 12:16 193阅读 0赞

### 一、在服务端创建客户端配置文件 ###

（1）在config服务端创建config-client.yml文件

（2）添加如下配置并push到远程仓库

spring:
      profiles:
        active: dev
    
    ---
    server:
      port: 8201
    # spring配置
    spring:
      profiles: dev # 开发环境
      application:
        name: springcloud-provider-dept
    
    # Eureka 配置 配置把服务注册到的地址
    eureka:
      client:
        service-url:
          defaultZone: http://eureka7001.com:7001/eureka/
    
    ---
    server:
      port: 8202
    # spring配置
    spring:
      profiles: test # 测试环境
      application:
        name: springcloud-provider-dept
    
    # Eureka 配置 配置把服务注册到的地址
    eureka:
      client:
        service-url:
          defaultZone: http://eureka7001.com:7001/eureka/

### 二、创建Config客户端模块 ###

（1）创建客户端

（2）导入依赖

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <parent>
            <artifactId>springcloud</artifactId>
            <groupId>com.buba</groupId>
            <version>1.0-SNAPSHOT</version>
        </parent>
        <modelVersion>4.0.0</modelVersion>
    
        <artifactId>springcloud-config-client-3355</artifactId>
    
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-config</artifactId>
            </dependency>
    
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-bootstrap</artifactId>
                <version>3.0.0</version>
            </dependency>
        </dependencies>
    </project>

（3）创建bootstrap.yml和application.yml

bootstrap.yml：系统级别的配置，优先级高。

spring:
      cloud:
        config:
          # 客户端连接服务端，服务端连接远程仓库
          uri: http://localhost:3344/
          name: config-client #需要从git上读取的资源名称，不需要后缀
          profile: dev # 哪个环境配置
          label: master # 哪个分支

*  application.yml：用户级别的配置。

spring:
      application:
        name: springcloud-config-client-3355

（4）编写Controller类

package com.buba.springcloud.controller;
    
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class ConfigClientController {
    
        @Value("${spring.application.name}")
        private String applicationName;
        @Value("${eureka.client.service-url.defaultZone}")
        private String eurekaServer;
        @Value("${server.port}")
        private String port;
    
        @RequestMapping("/config")
        public String getConfig() {
            return "applicationName：" + applicationName +
                    "eurekaServer：" + eurekaServer
                    + "port：" + port;
        }
    }

（5）编写启动类

package com.buba.springcloud;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class ConfigClient_3355 {
        public static void main(String[] args) {
            SpringApplication.run(ConfigClient_3355.class, args);
        }
    }

（6）启动服务端和客户端测试

访问地址：[http://localhost:3344/config-client-dev.yml][http_localhost_3344_config-client-dev.yml]

因为客户端端口号是远程获取的，所以访问地址[http://localhost:8201/config][http_localhost_8201_config]
