I need to use two *.properties file to determine config of Spring Boot application server. How can I set the second configuration path?

I use spring-boot-starter-parent version 1.5.10 and such *.properties file:

spring.datasource.url=url
spring.datasource.username=root
spring.datasource.password=password
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.jpa.show-sql=false
spring.jpa.hibernate.ddl-auto=update
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialec
spring.jpa.properties.hibernate.current_session_context_class=
org.springframewok.orm.hibernate4.SpringSessionContext
spring.jpa.properties.hibernate.enable_lazy_load_no_trans=true
spring.datasource.hikari.minimum-idle=5
spring.datasource.hikari.maximum-pool-size=10
spring.datasource.hikari.idle-timeout=30000

Now, I need to address database info from another properties file.

Edit: Note that I need to put second properties file outside of my WAR file in WEB-INF folder.

(1) This is best practices when switching between development mode and production environment.

https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-profiles.html#boot-features-profiles

Reference for version 1.5.10.RELEASE: https://docs.spring.io/spring-boot/docs/1.5.10.RELEASE/reference/htmlsingle/#boot-features-external-config-profile-specific-properties

For more specific, you create 3 files

application.properties for common properties.

application-dev.properties for only own properties what used in profile dev

application-production.properties for only own properties what used in profile production

(Notice: Has convention over naming)

Point profile what used, in application.properties has line spring.profiles.active=dev (in development) or spring.profiles.active=production (in production)

(2)

Note that I need to put second properties file outside of my WAR file in WEB-INF folder.

Assumption, your file is foo.properties. It is outside WAR file, it has not nature of Spring's properties file. Therefore, Spring Framework/Spring Boot can not read it automatically. You must write few lines of Java code to reading the content of foo.properties, then assign to configuration manually (see example configuration class)

  • I just edit my question, please make me advice based on that note – Narges May 03 '18 at 11:42
  • Bear in mind: File `*.properties` outsite WAR file, it is not Spring's properties. – Vy Do May 03 '18 at 11:52
  • Ok man, Thanks I got it. now I should search how to set properties from code – Narges May 03 '18 at 12:00
  • Consider using `spring.config.location` (an alternative for config by Java code) Reference: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html#boot-features-external-config-profile-specific-properties – Vy Do May 05 '18 at 10:16

You can access multiple of properties file using @PropertySource

Follow the following stackoverflow thread. https://stackoverflow.com/a/47178674/7538821
