How to rename application.properties file in Spring Boot application?


It is a standard practice that during our production deployments, our application loads property files from external locations. This helps us to change our configurations without changing our code. Sometimes we also change default file names according to our needs in production environment. In this page, we will come to know how to load external property file which is renamed into Spring Boot application.

By default, Spring Boot look for externalized default property file application.properties into given below predetermined locations:

 -- In the classpath root.

 -- In the package "/config" in classpath.

 -- In the current directory.

 -- In the "/config" directory of current folder.

Now lets say, you have renamed your default application.properties file like myapp.properties. There are 3 ways of loading it to your Spring Boot application.

Command line arguments

Use command line argument "--spring.config.name" to pass the renamed file name to the Spring Boot application as shown below:

Terminal
java -jar myAppBuild.jar --spring.config.name=myapp

Environment variables

In the second approach, you can configure your externalized configuration details into environment variables and your Spring Boot application will read it from your environment as shown below:

Terminal
set SPRING_CONFIG_NAME=myapp

java -jar myAppBuild.jar

Programatically loding configurations


SpringBootWebApplication
package com.java2novice.springboot;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.context.ConfigurableApplicationContext;

@SpringBootApplication
public class SpringBootWebApplication {

	private static Logger logger = LoggerFactory.getLogger(SpringBootWebApplication.class);

	public static void main(String[] args) throws Exception {

		ConfigurableApplicationContext applicationContext = new SpringApplicationBuilder(SpringBootWebApplication.class)
				.properties("spring.config.name:myapp")
				.build()
				.run(args);
	}
}
