Spring Cloud Config client not loading the value from config server - maven

Question

I am facing below issue while I try to run my Spring Cloud Config Client:
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
My dependencies in POM.xml are as below:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.6.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->

The bootstrap.yml
spring:
application:
name: my-config-client
cloud:
services:
registrationMethod: route
config:
enabled: true
uri: http://localhost:${config.port:8888}
The application.yml is as below:
# HTTP Server
server:
port: 2222
# Spring properties
spring:
profiles:
active: dev
#Disable HTTP Basic Authentication
security:
basic:
enabled: false
The class where I am trying to access the property is as below:
#RefreshScope
#Component
public class MyProperty {
#Value("${DATABASE_NAME}")
private String databaseName;
public String getDatabaseName() {
return databaseName;
}
}
My config server is running fine. When I use this url on browser http://localhost:8888/configserver/dev, It gives the below result:
{
"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"
}
}
]
}
I tried with all the posts who were facing this issue. But, it is not working for me. May be, I am missing some points. If anybody can provide help, it would be great.
Thanks

There are some breaking changes with the new spring cloud module read more: here.
Bootstrap, provided by spring-cloud-commons, is no longer enabled by
default. If your project requires it, it can be re-enabled by
properties or by a new starter.
To re-enable by properties set spring.cloud.bootstrap.enabled=true or spring.config.use-legacy-processing=true. These need to be set as
an environment variable, java system property or a command line
argument.
The other option is to include the new spring-cloud-starter-bootstrap
It worked for me by adding these dependencies:
<parent>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-parent</artifactId>
<version>2020.0.0</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>${spring-cloud.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>

I referred this post answered by 'spencergibb' and able to resolve the issue. I added "spring.config.name" in my bootstrap.yml file of client application and resolved the issue. Now, my bootstrap.yml look like as below:
spring:
application:
name: my-config-client
cloud:
services:
registrationMethod: route
config:
name: configserver
enabled: true
uri: http://localhost:${config.port:8888}
