我在尝试运行Spring Cloud Config Client时遇到以下问题：

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

我在POM.xml中的依赖项如下：

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

引导程序.yml

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

application.yml如下所示：

# 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http://localhost:8888/configserver/dev上使用此URL时，它会给出以下结果：

{  
   "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"
         }
      }
   ]
}

我试过了所有的帖子，但都不适合我。可能是我遗漏了一些要点。如果有人能提供帮助，那就太好了。
谢谢
