I have started with just a simple Spring Boot starter project.
I renamed application.properties
to application.yml
In application.yml file, I added just simple code:
test:
name: myAppName
I created a controller and added this piece of test code:
@RestController
public class Controller {
@Value("${test.name}")
private String name;
@GetMapping("/test")
public String test(){
return name;
}
}
Called it from Postman and it all worked good.
Then I added module named integration
that is consisted of two more modules user-service
and communication-service
And after when I would run the application I would get this error:
Could not resolve placeholder 'test.name' in value "${test.name}"

Integration
module POM
that is consistent of two more modules looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<artifactId>integration</artifactId>
<properties>
<maven.compiler.source>11</maven.compiler.source>
<maven.compiler.target>11</maven.compiler.target>
</properties>
</project>
And user-service
module POM
that is inside of integration
module looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

I am not sure what am I missing here and why I cant read application.yml file any more.
CodePudding user response:
Your parent pom is of pom
type and doesn't handle resources under src/main/resources
by the maven resources plugin in process-resources
stage.
You should move src/main/resources/application.yml
from the project root directory into either integration/user-service/src/main/resources
or integration/communication-service/src/main/resources
