I have following structure of my application

----

   | 

   |____SpringBootApplicationA

        |

        |

        |___module-1

        |___module-2

Each module has its own configuration, For example, module-1 is library that talks to mysql, it has its configuration (connection string, username, password,etc...)

Now I want to represent this configuration in the form of Java POJO in module-1. application.yml and a bean that read configuration and sets the values.

For example

class Module1Config {



  private String key1;

  private String key2;



  // getters & setters

}

application.yml at module-1

key1: val1

key2: val2

now as a consumer of module-1, SpringBootApplicationA will receive module-1's configuration which is what set as default by module-1.

On the consumer side it will have application configuration like this

someKey1: someVal1

someKey2: someVal2

module-1:

  key1: overrideVal1

and when initialization happens of module-1's beans, I want the values to be seen as

key1: overrideVal1

key2: val2

How to configure spring boot to respect default values and override them ?

Edit

class AppConfig {



  private String key1;

  private int key2;



  private Module1Config conf;



  // getters + setters



}

This is my example application config, as you can see it has some specific to application config and other configs it is leveraging from other modules.

I want conf object to get assigned default set of value from module1 and then whatever application has specified as an override

Spring boot by default loads application.yml file
from src/main/resources
You can declare another application.yml file in
config folder of root path and configuration from
config folder will override configuration from src/main/resources

Config locations are searched in reverse order. By default, the configured locations are classpath:/,classpath:/config/,file:./,file:./config/. The resulting search order is the following:

file:./config/
file:./
classpath:/config/
classpath:/
