I am trying to use @ConfigurationValue which should read values from project-defaults.yml, however, I am experiencing strange behaviour, see code hereunder.
MyController:
@ApplicationScoped
@Path("/app")
public class MyController {
@Inject
@ConfigurationValue("database.name")
private String name;
@GET
@Path("/name-1")
@Produces(MediaType.TEXT_PLAIN)
public String name1() {
return String.valueOf(name); // displays postgres
}
@GET
@Path("/name-2")
@Produces(MediaType.TEXT_PLAIN)
public String name2() {
return String.valueOf(new Configuration().getName()); // displays null
}
}
@ApplicationScoped
class Configuration {
@Inject
@ConfigurationValue("database.name")
private String name;
public String getName() {
return name;
}
}
project-defaults.yml
database:
name: postgres

The value database.name is injected when used inside MyController class, but not when inside Configuration class.
I am using thorntail version 2.3.0.Final-SNAPSHOT.
Do you have any ideas what could be causing it? Thanks.
The problem was in this line of code:
new Configuration().getName()
I should inject the Configuration object instead, like this:
@ApplicationScoped
@Path("/app")
public class MyController {
@Inject
@ConfigurationValue("database.name")
private String name;
@Inject
private Configuration configuration;
}
