multiple-yml-sample's Introduction

Spring Boot Sample

As of Spring Boot version 2.0.0.M7(2017-12-17)
multiple config files for each environment
config files

app-key-{environment}.yml

environment	default	local	prod
key	val-default
key1	val1-default	val1-local
key2	val2-default		val2-prod

app-api-{environment}.yml

environment	default	local	prod
timeout	3
retry-count	1	5	3

If you use the below parameter

--spring.profiles.active=local

then you can get value from config file , depends on envisonment

*** app-key-config:key=[val-default] key1=[val1-local] key2=[val2-default] *** app-api-config:timeout=[3] retryCount=[5]

If you use the prod parameter

--spring.profiles.active=prod

*** app-key-config:key=[val-default] key1=[val1-default] key2=[val2-prod] *** app-api-config:timeout=[3] retryCount=[3]

There are config files like below

└── resources
├── application.yml
└── config
  ├── app-api-local.yml
  ├── app-api-prod.yml
  ├── app-api.yml
  ├── app-key-local.yml
  ├── app-key-prod.yml
  └── app-key.yml

I use @PropertySource to each config file

AppKeyConfig.java

@Configuration
@EnableConfigurationProperties
@PropertySource({"classpath:/config/app-key.yml","classpath:/config/app-key-${spring.profiles.active}.yml"})
@ConfigurationProperties
public class AppKeyConfig {
  private String key;
  private String key1;
  private String key2;
...

AppApiConfig.java

@Configuration
@PropertySource({"classpath:/config/app-api.yml","classpath:/config/app-api-${spring.profiles.active}.yml"})
@ConfigurationProperties
public class AppApiConfig {
  private int timeout;
  private int retryCount;
...
