propertySources Shows Empty (Spring Cloud Config)

Question

I am trying to learn Spring Cloud. So I created a new project using Spring Starter (a very basic one)

I configured my application.properties like so:

server.port=9090
spring.cloud.config.server.native.searchLocations=file://H:/opt/app/app.static.properties
spring.profiles.active=native

But when I start my Spring Boot application, it starts fine (from what I can say), but when I hit URL http://localhost:9090/config/default/master

I get the output on the browser:

{"name":"config","profiles":["default"],"label":"master","version":null,"state":null,"propertySources":[]}

My Console output is:

Shouldn't the propertySources be full of the property file entries? I am new to this. So mostly learning from tutorials and guides. Is my understanding correct?

Any help would be appreciated. Thanks.

Answer 1

It is usually a problem of file name or file path location. It was not working in my case because of the file name. I extended my file name to -dev and added it to the URL. It worked.

Answer 2

if you are using notepad, remove .txt and save the file as .properties file

Answer 3

Try adding prop spring.cloud.config.server.git.searchPaths. This will tell spring in which path your property files are.

spring.profiles.active=git
spring.cloud.config.server.git.uri=https://gitlab.com/<project-name>/<app-name>.git
spring.cloud.config.server.git.clone-on-start=true
spring.cloud.config.server.git.default-label=main
spring.cloud.config.server.git.username=git-username
spring.cloud.config.server.git.password=your-access-token-from-git
spring.cloud.config.server.git.searchPaths=path*

Answer 4

If you created the file using a notepad, it will put the extension of the file like limits-service.properties.txt , instead you need the file name limits-service.properties . I tried renaming the file from CMD and it worked .

rename limits-service.properties.txt to limits-service.properties

Answer 5

I got the same error followed the below steps.

Application properties is as below:

spring.application.name=spring-cloud-config-server
server.port=8888
logging.level.web=DEBUG
spring.cloud.config.server.git.uri=file:///C:/Users/DELL/git-localconfig-repo

Added dependency:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency> 

In limits-service pom.xml file

If it still does not work, try to delete limits-service.properties and create a new one, or else try creating limits-service-dev.properties, limits-service-prod.properties and call them by URLs http://localhost:8888/limits-service/dev and check if those work ..

Issue is mostly i guess with path or file name.

Answer 6

The searchLocations property accepts a location of files and/or sub-directories. try spring.cloud.config.server.native.searchLocations=file://H:/opt/app/ instead of spring.cloud.config.server.native.searchLocations=file://H:/opt/app/app.static.properties and hit http://localhost:9090/config/default/master/app.static.properties
