Spring Cloud Config 客户端未从配置服务器加载值

当我尝试运行 Spring Cloud Config Client 时，我遇到以下问题：

Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'DATABASE_NAME' in string value "${DATABASE_NAME}"
    at org.springframework.util.PropertyPlaceholderHelper.parseStringValue(PropertyPlaceholderHelper.java:174)
    at org.springframework.util.PropertyPlaceholderHelper.replacePlaceholders(PropertyPlaceholderHelper.java:126)
    at org.springframework.core.env.AbstractPropertyResolver.doResolvePlaceholders(AbstractPropertyResolver.java:204

我的依赖项在POM.xml如下：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.3.6.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

    </dependency>

</dependencies>

The bootstrap.yml

spring:
application:
name: my-config-client
cloud:
services:
  registrationMethod: route
config:
  enabled: true
  uri: http://localhost:${config.port:8888}

The 应用程序.yml如下：

# HTTP Server
server:
port: 2222

# Spring properties
spring:
  profiles: 
    active: dev

#Disable HTTP Basic Authentication
security:
  basic:
    enabled: false

我尝试访问该属性的类如下：

@RefreshScope
@Component
public class MyProperty {

    @Value("${DATABASE_NAME}")
    private String databaseName;


    public String getDatabaseName() {
        return databaseName;
    }
}

我的配置服务器运行良好。当我在浏览器上使用这个网址时http://localhost:8888/configserver/dev http://localhost:8888/configserver/dev，给出以下结果：

{  
   "name":"configserver",
   "profiles":[  
      "dev"
   ],
   "label":"master",
   "version":"c991526a93fb776e37e18e138c7485d894d6ea4f",
   "propertySources":[  
      {  
         "name":"https://onestash.abc.com/scm/kapmol/microservice-config-repo.git/configserver.properties",
         "source":{  
            "DATABASE_NAME":"ABC",
            "CONVERT_USERS":"Y",
            "LRDS_JNDI_NAME":"jdbc/tds_new"
         }
      }
   ]
}

我尝试了所有面临这个问题的帖子。但是，它对我不起作用。可能是，我遗漏了一些要点。如果有人可以提供帮助，那就太好了。

Thanks

新的 Spring Cloud 模块有一些重大变化，请阅读更多内容：here. https://github.com/spring-cloud/spring-cloud-release/wiki/Spring-Cloud-2020.0-Release-Notes#breaking-changes

由 spring-cloud-commons 提供的 Bootstrap 不再启用 默认。如果您的项目需要它，可以通过以下方式重新启用它 属性或由新启动器。

• 要通过属性重新启用，请设置 spring.cloud.bootstrap.enabled=true 或 spring.config.use-legacy-processing=true。这些需要设置为 环境变量、java 系统属性或命令行 争论。

• 另一个选项是包含新的 spring-cloud-starter-bootstrap

它通过添加这些依赖项对我有用：
