Springcloud-Config客户端配置与测试

Config客户端配置与测试

环境搭建
问题随时而来，分布式配置的动态刷新

环境搭建

1、新建cloud-config-client-3355

2、pom

<dependencies>
        <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>com.atguigu.springcloud</groupId>
            <artifactId>cloud-api-commons</artifactId>
            <version>${project.version}</version>
        </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>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

3、bootstrap.yml
①是什么？
在这里插入图片描述
记住，客户端的yml文件一定要是bootstrap.yml，因为自己的bootstrap.yml和从配置中心拉取得application,yml和起来才是该微服务完整的配置文件，如果你本地也是application.yml则会和从配置中心拉取的冲突，导致启动失败等。

②内容

server:
  port: 3355
spring:
  application:
    name: config-client
  cloud:
    config:
      label: master  # 分支名称
      name: config   # 配置文件名称
      profile: dev   # 配置文件后缀  综合 上面三个就是，master分支上的config-dev文件被读取，即http://localhost:3344/master/config-dev
      uri: http://localhost:3344  # 配置中心地址
eureka:
  client:
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka

4、主启动类

@SpringBootApplication
public class ConfigClientMain3355 {
    public static void main(String[] args) {
            SpringApplication.run( ConfigClientMain3355.class,args);
        }
}

5、业务类

@RestController
public class ConfigClientController {
    @Value("${config.info}") //相当于从配置中心读取了application.yml,然后从其中读取config.info
    private String configInfo;
    @GetMapping("/configInfo")
    public String getConfigInfo(){
        return configInfo;
    }
}
