一、问题现象

springcloud configClient获取configServer信息失败导致启动configClient注入失败

报错堆栈信息

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

Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'version' in value "${version}"

二、解决方案

经排查，原因为gitee配置文件名config-dev.properties与服务注册名不一致导致，bootstrap.yml配置了configServer地址之后，configClient从gitee中获取配置文件的时候指定了profile(dev哪个环境)以及label(newBranch4分支)，但是configServer获取配置文件的时候会批量加载所有分支的配置文件信息，因此configClient和configServer配置文件关联必须由服务名以及文件名关联，因此在修改gitee中配置文件的文件名为服务名之后，configClient启动成功，并成功获取gitee中相关配置信息。

gitee中配置文件内容

git clone https://gitee.com/fzggz/springcloud.git

configServer工程的bootstrap.yml

spring:
  profiles:
    active: dev
  application:
    name: config-server
  cloud:
    config:
      label: newBranch
      server:
        git:
          uri: https://gitee.com/fzggz/springcloud
          searchPaths: spring-cloud-config-file
          timeout: 60
          username: ***
          password: ***
          default-label: newBranch
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
bobo:
  user:
    name: bobo
    age: 18

configClient的bootstrap.yml

spring:
  application:
    name: config-client
  cloud:
    config:
      uri: http://127.0.0.1:8030  # 直接连接 Config-Server
      profile: dev
      label: newBranch3
      discovery:
        enabled: false
#        enabled: true
#        service-id: config-server
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

三、运行结果

configClient配置客户端代码，启动configClient后，读取configServer中读取到的配置文件信息，通过文件名，profile，label等映射关系找到version，通过@Value注入version，controller中获取

package com.ggz.configclient.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author ggz on 2025/4/1
 */
@RefreshScope
@RestController
public class TestController {

    @Value("${version}")
    private String version;

    @RequestMapping("/version")
    public String version() {
        return version;
    }
}
