[JAVA] Set Spring profile when executing bootRun task with Spring Boot Gradle Plugin


In jvmArgs of bootRun task setting of build.gradle, you can specify the profile in the system property value spring.profiles.active.


//Add settings for the bootRun task
bootRun {
  //Specify the foobar profile
  jvmArgs = ['-Dspring.profiles.active=foobar']


Operation check

I generated the source code with Spring Initializr and added / deleted / edited it as needed.

This environment

Source code list

├── build.gradle
├── settings.gradle
└── src
    └── main
        ├── java
        │   └── com
        │       └── example
        │           └── demo
        │               └── DemoApplication.java
        └── resources
            ├── application-foobar.properties
            └── application.properties


Build configuration file for Gradle. Adding settings for the bootRun task.


plugins {
  id 'org.springframework.boot' version '2.2.2.RELEASE'
  id 'io.spring.dependency-management' version '1.0.8.RELEASE'
  id 'java'

group = 'com.example'
version = '0.0.1'
sourceCompatibility = '11'

repositories {

dependencies {
  implementation 'org.springframework.boot:spring-boot-starter-web'
  testImplementation('org.springframework.boot:spring-boot-starter-test') {
    exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'

test {

//Add settings for the bootRun task
bootRun {
  //Specify a profile
  jvmArgs = ['-Dspring.profiles.active=foobar']


The one generated by Spring Initializr is used as it is.


rootProject.name = 'demo'


A process that returns JSON when the top page is accessed has been added.

package com.example.demo;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.core.env.Environment;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.HashMap;
import java.util.Map;

public class DemoApplication {

  public static void main(String[] args) {
    SpringApplication.run(DemoApplication.class, args);

  private Environment env;

  //Returns JSON when accessing the top page
  public ResponseEntity<Map<String, Object>> top() {

    Map<String, Object> body = new HashMap<>();

    //Applicable profile
    body.put("profiles", env.getActiveProfiles());

    // application-*.Value obtained from properties
    body.put("my.sample", env.getProperty("my.sample"));
    body.put("my.message", env.getProperty("my.message"));

    return new ResponseEntity<>(body, HttpStatus.OK);


The default property settings file. If you do not specify a profile, you can use the values in this file.

my.sample=This is a sample property.
my.message=This is a application.properties.


Property settings file when using the foobar profile. When using the foobar profile, the value in application.properties is overwritten with the value in this file.

my.message=This is a application-foobar.properties.

Operation check

Start Spring Boot with the gradle bootRun command.

$ gradle bootRun

> Task :bootRun

  .   ____          _            __ _ _
 /\\ / ___'_ __ _ _(_)_ __  __ _ \ \ \ \
( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \
 \\/  ___)| |_)| | | | | || (_| |  ) ) ) )
  '  |____| .__|_| |_|_| |_\__, | / / / /
 :: Spring Boot ::        (v2.2.2.RELEASE)

If you access it with curl from another console etc., JSON will be returned.

If the bootRun task setting of gradle.build is not described, the following JSON will be returned. The value of application.properties is output.

$ curl http://localhost:8080/
{"my.sample":"This is a sample property.","profiles":[],"my.message":"This is a application.properties."}

If jvmArgs = ['-Dspring.profiles.active = foobar'] is described in the bootRun task setting of gradle.build, the following JSON will be returned. The value of application-foobar.properties is output with priority over the value of application.properties.

$ curl http://localhost:8080/
{"my.sample":"This is a sample property.","profiles":["foobar"],"my.message":"This is a application-foobar.properties."}
