Mastering IntelliJ and Changing Spring Boot Property Location: A Step-by-Step Guide

Are you tired of dealing with the hassle of configuring Spring Boot properties in your IntelliJ project? Do you struggle to find the right place to put your application.properties or application.yml file? Worry no more! This comprehensive guide will walk you through the process of changing the Spring Boot property location in IntelliJ, making your development life easier and more efficient.

Why Change the Spring Boot Property Location?

By default, Spring Boot projects in IntelliJ look for application.properties or application.yml files in the root of the classpath, which is usually the src/main/resources directory. However, there are scenarios where you might want to change this default behavior. For example:

• You want to keep your configuration files separate from your code.
• You need to use environment-specific properties (e.g., dev, prod, staging).
• You want to externalize your configuration to a separate file or repository.

In this article, we’ll explore the different ways to change the Spring Boot property location in IntelliJ and make your life as a developer more convenient.

Method 1: Using the spring.config.location Property

One way to change the Spring Boot property location is by using the spring.config.location property. This property allows you to specify the location of your application.properties or application.yml file.

To use this method, follow these steps:

1. Create a new file called application.properties (or application.yml) in the desired location (e.g., src/main/config). Add your configuration properties to this file.
2. In your IntelliJ project, go to the Run menu and select Edit Configurations....
3. In the Run/Debug Configurations window, click on the Environment tab.
4. In the Environment Variables section, add a new variable called spring.config.location with the value pointing to the location of your application.properties (or application.yml) file. For example: file:src/main/config/.
5. Click Apply and then OK to save the changes.

spring.config.location=file:src/main/config/

Method 2: Using the @PropertySource Annotation

Another way to change the Spring Boot property location is by using the @PropertySource annotation on your Spring Boot application configuration class.

To use this method, follow these steps:

1. Create a new file called application.properties (or application.yml) in the desired location (e.g., src/main/config). Add your configuration properties to this file.
2. In your Spring Boot application configuration class (usually Application.java), add the @PropertySource annotation, specifying the location of your application.properties (or application.yml) file. For example:

@SpringBootApplication
@PropertySource("file:src/main/config/application.properties")
public class Application {
  // ...
}

Method 3: Using the spring.config.additional-location Property

The third way to change the Spring Boot property location is by using the spring.config.additional-location property. This property allows you to specify additional locations for your application.properties or application.yml file.

To use this method, follow these steps:

1. Create a new file called application.properties (or application.yml) in the desired location (e.g., src/main/config). Add your configuration properties to this file.
2. In your IntelliJ project, go to the Run menu and select Edit Configurations....
3. In the Run/Debug Configurations window, click on the Environment tab.
4. In the Environment Variables section, add a new variable called spring.config.additional-location with the value pointing to the location of your application.properties (or application.yml) file. For example: file:src/main/config/.
5. Click Apply and then OK to save the changes.

spring.config.additional-location=file:src/main/config/

Which Method to Choose?

So, which method should you choose? It depends on your specific use case and requirements. Here’s a brief summary of each method:

Method	Advantages	Disadvantages
Using spring.config.location	Easy to configure Can be used with environment variables	Only one location can be specified
Using @PropertySource	Flexibility to specify multiple locations Can be used with Java-based configuration	Only works with Java-based configuration
Using spring.config.additional-location	Easy to configure Can be used with multiple locations	Only works with environment variables

In conclusion, changing the Spring Boot property location in IntelliJ can be done using three different methods: spring.config.location, @PropertySource, and spring.config.additional-location. Each method has its advantages and disadvantages, and the choice ultimately depends on your specific use case and requirements. By following the instructions in this article, you’ll be able to easily configure and manage your Spring Boot properties in IntelliJ.

Best Practices

Here are some best practices to keep in mind when changing the Spring Boot property location in IntelliJ:

• Keep your configuration files separate from your code.
• Use environment-specific properties (e.g., dev, prod, staging).
• Externalize your configuration to a separate file or repository.
• Use the spring.config.location property for simple configurations.
• Use the @PropertySource annotation for Java-based configurations.
• Use the spring.config.additional-location property for multiple locations.

By following these best practices and using the methods outlined in this article, you’ll be able to effectively manage your Spring Boot properties in IntelliJ and make your development life easier and more efficient.
