Spring Cloud 配置客户端无法解析值“${driverClassName}”中的占位符 'driverClassName'

Question

我有带有本地文件的配置服务器

D:\Projects\config-server1\src\main\resources\config\db.properties

driverClassName=com.mysql.driver
username=rootdb
password=mypwddb

并配置服务器application.properties

server.port=8888
spring.profiles.active=native

当我访问 http://localhost:8888/db/default 服务器返回时

{"name":"db","profiles":["default"],"label":null,"version":null,"state":null,"propertySources":[{"name":"classpath:/config/db.properties","source":{"driverClassName":"com.mysql.driver","username":"rootdb","password":"qwaszxdb"}},{"name":"classpath:/application.properties","source":{"server.port":"8888","spring.profiles.active":"native"}}]}

下一步，我创建配置客户端

我的配置客户端的application.properties

server.port=8030
spring.application.name=db
spring.profiles.active=default
spring.cloud.config.url=localhost:8888

主类没什么特别的

@SpringBootApplication
public class ConfigClient7Application {
    public static void main(String[] args) {
        SpringApplication.run(ConfigClient7Application.class, args);
    }
}

还有我的 Controller ，当我尝试使用@Value()

package com;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class DbController {

    @Value("${driverClassName}")
    String driverClassName;

    @GetMapping("/")
    public String myMethod(){
        return driverClassName;
    }
}

我已经尝试了数百种选择，但总是出错

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dbController': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'driverClassName' in value "${driverClassName}"

找了一整天的错误，结果什么也没找到任何人都可以提出问题所在吗？
