  • springcloud-服务读取Config配置中心

      1.新建一个模块,用于读取配置中心的配置

      2.添加依赖

    <dependencies>
            <!-- 若要读取configServer的配置信息,需要添加configCilent的依赖 -->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-config</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-actuator</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-devtools</artifactId>
                <scope>runtime</scope>
                <optional>true</optional>
            </dependency>
            <dependency>
                <groupId>cn.aib.springcloud</groupId>
                <artifactId>springclud-api-common</artifactId>
                <version>1.0-SNAPSHOT</version>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>
        </dependencies>

      3.添加配置;这次新建不是application.yml,而是bootstrap.yml,两者的区别:

        1. bootstrap.yml优先applicaiton.yml先被加载执行;

        2. bootstrap.yml配置一些系统级别的配置。而applicaiton.yml配置一些用户级别的配置。

      目前我们这种情况,在bootstrap.yml配置一些信息用于读取配置中心的配置内容。在applicaiton.yml配置自己私有的配置。这样的好处能 配置分明,不用全部挤在一个配置文件里

    server:
      port: 3355
    
    spring:
      application:
        name: config-client
      cloud:
        config:
          label: main #表示分支名;这里不再是master,是main
          name: config  #配置文件的名称;比如github上面的config-dev.yml,那配置文件名称为config
          profile: dev  #文件的开发环境
          uri: http://localhost:3344 #配置中心的URL
    eureka:
      client:
        service-url:
          defaultZone: http://localhost:7001/eureka

      4.主启动

    @SpringBootApplication
    @EnableEurekaClient
    public class ConfigClient3355Application {
        public static void main(String[] args) {
            SpringApplication.run(ConfigClient3355Application.class, args);
        }
    }

      5.业务

    @RestController
    public class ConfigClientController {
    
        @Value("${config.info}")
        private String configInfo;
    
        @GetMapping("/configInfo")
        public String getConfigInfo(){
            return configInfo;
        }
    
    }

      6.测试;访问http://localhost/configinfo
