How to Configure Spring Boot Config Server with a File-Based Property Source

Spring Boot and Spring Cloud provide powerful frameworks and tools for building cloud-native applications. One of the essential features is the Spring Boot Config Server which centralizes external configuration for distributed systems. This guide will guide you through the steps to configure a Spring Boot Config Server to use a file-based property source.

What is Spring Boot Config Server?

Spring Boot Config Server is a tool that serves as a centralized configuration for applications across different environments. It allows you to manage your application settings from a central repository, making it easier to maintain and change configuration without redeploying applications.

Steps to Configure File-Based Property Source

To configure the Spring Boot Config Server to use a file-based property source, follow these steps:

Create a Spring Boot Configuration Server

First, you need to create a Spring Boot application and add the necessary dependencies for the Config Server. In your pom.xml file, include the following dependencies:

In this configuration:

server.port sets the server port to 8888.

spring.cloud.config.server.native.search-locations specifies the locations where the Config Server will look for configuration files. You can provide multiple locations by separating them with commas.

Place Property Files

Ensure you have your configuration files placed in the corresponding directories specified in search-locations. For example:

Run the Config Server

Start your Config Server by running the main application class. The server should now serve configurations from the specified file locations.

Accessing Configurations

Clients can access their configurations by making a request to the server’s endpoint. For example, to get the configuration for myapp running in the dev profile:
