Quarkus Consul Config: how to inject application.yaml file from Consul Agent?

I am using Quarkus inside a microservice Java application.
I recently started to migrate from Spring Boot to Quarkus itself.
I am having some trouble while migrating "Spring Cloud Consul" to "Quarkus Consul Config". In order to be more specific, I am getting the following error:
java.lang.RuntimeException: Key 'my/consul/path/application.yaml' not found in Consul
at io.quarkus.consul.config.runtime.ConsulConfigSourceProvider$1.accept(ConsulConfigSourceProvider.java:66)
at io.quarkus.consul.config.runtime.ConsulConfigSourceProvider$1.accept(ConsulConfigSourceProvider.java:56)

(...)
Inside my Consul instance, the key my/consul/path/application.yaml corresponds to an application.yaml external file that I would like to import from there during the startup phase.
Below you can find my consul config (application.yaml):
quarkus:
application:
name: myapplication
consul-config:
enabled: true
properties-value-keys: my/consul/path/application.yaml
agent:
host-port: http://localhost:9500
prefix: myappprefix
If I try to switch from properties-value-keys to properties-raw-value-keys, I see that my property is not being injected inside my application context:
#ConfigProperty(name = "consultest")
String test;
java.util.NoSuchElementException: SRCFG00014: The config property consultest is required but it could not be found in any config source
Below you can find the application.yaml content (located on Consul):
consultest: testtest
The intent, here, is to delegate application.yaml properties to Consul, divided by environment (dev, test, prod).
I would like to threat my local application.yaml file (located in src/main/resources) as a bootstrap.yaml file, similarly to Spring Boot approach.
How could this be done with Quarkus? Thank you a lot for your support.

How can a library module of a Spring application add additional configuration to the application's `application.yml`?

I have a Spring Boot application built with Maven which uses JDBC. The application.yml file has
spring:
application:
(stuff)
datasource:
url: jdbc:informix-sqli://......
driver-class-name: com.informix.jdbc.IfxDriver
I want to move the JDBC specific parts into a library so now the app/src/main/resources/application.yml only contains
spring:
application:
(stuff)
and the datasource configuration parameters need to live in the library repository. I tried creating lib/src/main/resources/application.yml with
spring:
datasource:
url: jdbc:informix-sqli://......
driver-class-name: com.informix.jdbc.IfxDriver
hoping that both the yml files would be picked up and merged when Spring loads up. Apparently not.
The library and application build fine, but when I run it
***************************
APPLICATION FAILED TO START
***************************
Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
How can I get the configuration in the library to be merged into the application.yml configuration in the application?

I have always found "merging" of external configuration from sub-modules with spring-boot to be problematic at worst, confusing at best. I now organize all external configuration using one of two approaches. But first, there are multiple ways to specify external configuration that you should be aware of:
Spring Boot and multiple external configuration files
Starting Spring Application by merging yml files
https://docs.spring.io/spring-boot/docs/current/reference/html/spring-boot-features.html#boot-features-external-config
I previously would specify multiple locations and that sort-of worked. But, I now typically use one of two approaches to avoid confusion:
I use profiles and specify multiple profiles at runtime when launching the spring boot app. i.e. Multiple profiles like "shared-common, shared-jdbc, deploy-prod" which will load "application-shared-jdbc.yml" out the sub-module.
or
I create a module that contains nothing but configuration files that get used by all related modules, often with multiple profiles for different configuration scenarios. All other modules (executable and libraries) depend on this shared configuration module.
AFAICT, spring-boot's external configuration handling not setup ideally for having standalone submodule configuration. It's more oriented around the notion that configuration belongs to runtime/executable modules, not libraries.

you can use #PropertySource. you have to implement your own PropertySourceFactory
if your props is in yaml format. then define it in the PropertySource
#PropertySource(value = ResourceUtils.CLASSPATH_URL_PREFIX
+ "application.yml", factory = Factory.class)

SpringBoot 2 with Flyway: spring.flyway.locations is ignored

I am using Spring Boot 2.2.2 with Flyway 5.2.4 and I tried to configure flyway to use a differente location for the scripts, but spring.flyway.locations=filesystem:db_other/migration/{vendor} neither flyway.locations=filesystem:db_other/migration/{vendor} configurations on application.properties worked.
When running the program, the following exception appear in the log:
FlywayMigrationScriptMissingException: Cannot find migration scripts in: [classpath:db/migration]
I already tried using Spring Boot 2.2.1, 2.2.0, 2.1.11 and Flyway 6.1.0 and 6.1.3, but the result is the same.

The default value for that property is classpath:db/migration as shown here (search for flyway).
Since you're using a different folder in the resources directory you should only need to change "filesystem" to "classpath" in your application.properties value.

Actually if was my fault: as I used to work with just spring (not spring boot) I configured my test class with the annotations #ExtendWith(SpringExtension.class) AND #ContextConfiguration(classes = { MyConfiguration.class }) instead of just use #SpringBootTest. When making this change the test worked.

Spring boot 2.1.1, use postgres config with jpa

I build some simple spring boot project, with jpa/postgres.
But when i debug this project, error say
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
But in my application.properties that have url.
spring.datasource.url=jdbc:postgresql://localhost:5432/oauth?currentSchema=oauth
spring.datasource.username=SOME_USER_NAME
spring.datasource.password=SOME_PASSWORD
spring.datasource.driverClassName=org.postgresql.Driver
spring.jpa.hibernate.ddl-auto=validate
#hibernate
spring.jpa.database = postgresql
spring.jpa.show-sql = true
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
Does anyone know about this?
if validation is trouble than debug don't say like 'url attribute is not specified'.
And My application.properties name 'application-test.properties', and in debug configuration set 'test', and also log say 'the profiles test are currently active'.
It looks like properties is not matching, but log said profile is matched.
It makes me very confuse..

I found problem. Jonathan Johx and TinyOS is right, Thanks for them.
If project built by spring boot 2.1.1, Intellij with postgres, then Override build.gradle and pom.xml.
In Spring-boot 2.1.1 (I still don't know why default value is it)
default setting is
runtime('org.postgresql:postgresql')
but If you want to run right, than must write 'compile' like this.
compile group: 'org.postgresql', name: 'postgresql', version: '42.2.5'
version is not important. just find in maven repo what you want version.

Spring boot: Oracle RAC DB connection configuration

In Spring boot application, Need to configure Oracle RAC DB URL. Can someone explain how to configure the Oracle RAC URL in application.properties?
jdbc:oracle:thin:#(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL={PROTOCOL})(HOST={{URL})(PORT={PORT})))(CONNECT_DATA=(SERVICE_NAME={SERVICE_NAME})))
Have verified the Spring boot official doc and didn't find anything related. Even verified in the Common Properties and can't find any references.
https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html
Thanks for your help in advance!

Try with below.
jdbc:oracle:thin:#(DESCRIPTION=
# (LOAD_BALANCE=on)
# (ADDRESS=(PROTOCOL=TCP)(HOST=host1) (PORT=1521))
# (ADDRESS=(PROTOCOL=TCP)(HOST=host2)(PORT=1521))
# (CONNECT_DATA=(SERVICE_NAME=service_name)))
OR
# Oracle settings
spring.datasource.url=jdbc:oracle:thin:#localhost:1522:orcl
spring.datasource.username=HIBERNATE_TEST
spring.datasource.password=HIBERNATE_TEST
spring.datasource.driver.class=oracle.jdbc.driver.OracleDriver
OR
jdbc:oracle:thin:#(DESCRIPTION=(ADDRESS_LIST=(LOAD_BALANCE=OFF)(FAILOVER=ON)
(ADDRESS=(PROTOCOL=TCP)(HOST=tst-db1.myco.com)(PORT=1604))
(ADDRESS=(PROTOCOL=TCP)(HOST=tst-db2.myco.com)(PORT=1604)))
(CONNECT_DATA=(SERVICE_NAME=mydb1.myco.com)(SERVER=DEDICATED)))

This is what i did to connect to postgres in my project and it is in production now. For Oracle it is exactly same. In fact for any other RDBMS.
Add the properties in the application.yml or the application.properties in the spring boot project.
The below is yml configuration.
spring:
jpa:
database: POSTGRESQL
show-sql: false
datasource:
platform: postgres
url: jdbc:postgresql://123.3.4.89.com:1234/DatabaseName
username: user123
password: pass123
driver-class-name: org.postgresql.Driver
testWhileIdle: true
validationQuery: SELECT 1
Then add the driver in the pom or the gradle build file which build tool you are using.
And the jpa jar of spring boot.
This was entry in the build.gradle file.
compile ('org.springframework.boot:spring-boot-starter-data-jpa')
compile group: 'org.postgresql', name: 'postgresql', version: '42.2.2'
Thats it, now you can create your repositories and start pushing and fetching data in the Db.
Hope this helps, cheers !!!
