Get the current active profile in Spring Boot

This post will discuss how to get the current active profile in Spring Boot.

There are several ways to get the current active profile in Spring Boot, which is a way to specify different configurations or behaviors for different environments, such as development, testing, or production. Here are some of the possible methods:

1. Using `@Autowired` Annotation

Using the @Autowired annotation to inject the Environment bean into a class, and then using the getActiveProfiles() method to return an array of strings that represent the active profiles.

// Import the annotation

import org.springframework.beans.factory.annotation.Autowired;

// Define a class that uses the Environment bean

public class MyService

{

// Inject the Environment bean

@Autowired

private Environment environment;

// Define a method that prints the active profiles

public void printActiveProfiles() {

// Get the array of active profiles

String[] activeProfiles = environment.getActiveProfiles();

// Print each profile

for (String profile : activeProfiles) {

System.out.println(profile);

}

2. Using `@Value` Annotation

Using the @Value annotation to bind the value of the spring.profiles.active property to a field or a parameter, and then using the field or the parameter to access the active profiles. The spring.profiles.active property can be set in various ways, such as in the application.properties file, as a command-line argument, or as an environment variable.

// Import the annotation

import org.springframework.beans.factory.annotation.Value;

// Define a class that uses the @Value annotation

public class MyService

{

// Bind the value of the spring.profiles.active property to a field

@Value("${spring.profiles.active}")

private String activeProfiles;

// Define a method that prints the active profiles

public void printActiveProfiles() {

// Print the field value

System.out.println(activeProfiles);

}

3. Using `WebMvcConfigurer` Interface

Using the WebMvcConfigurer interface to implement a configuration class that overrides the addCorsMappings() method, and then using the CorsRegistry parameter to access the active profiles. The WebMvcConfigurer interface provides various methods to customize the web application configuration, such as enabling CORS (Cross-Origin Resource Sharing) for specific URL patterns.

// Import the interface

import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

// Define a configuration class that implements the interface

@Configuration

public class WebConfig implements WebMvcConfigurer

{

// Override the addCorsMappings method

@Override

public void addCorsMappings(CorsRegistry registry) {

// Get the array of active profiles from the registry

String[] activeProfiles = registry.getEnvironment().getActiveProfiles();

// Print each profile

for (String profile : activeProfiles) {

System.out.println(profile);

}

That’s all about getting the current active profile in Spring Boot.
