- Spring boot is a module that provides rapid application development feature to the spring framework including auto-configuration<\/strong>, standalone-code<\/strong>, and production-ready<\/strong> code<\/li>\n
- It creates applications that are packaged as jar<\/em> and are directly started using embedded servlet container (such as Tomcat, Jetty or Undertow). Thus, no need to deploy the war<\/em> files<\/li>\n
- It simplifies the maven configuration by providing the starter template and helps to resolve the dependency conflicts. It automatically identifies the required dependencies and imports them in the application<\/li>\n
- It helps in removing the boilerplate code, extra annotations, and xml configurations<\/li>\n
- It provides a powerful batch processing and manages the rest endpoints<\/li>\n
- It provides an efficient jpa-starter library<\/em> to effectively connect the application with the relational databases<\/li>\n
- It offers a Microservice architecture and cloud configuration that manages all the application related configuration properties in a centralized manner.<\/li>\n<\/ul>\n
1.2 What are Profiles in Spring boot?<\/h3>\n
Profiles in simple term can be termed as the different environments which every application comprises of. For example \u2013 DEV, QA, or PROD. Each environment has its own specific requirement i.e. database connection, pipeline, and deployment configuration. In spring we maintain profiles with the help of properties and file files.<\/p>\n
In this article, we will create a QA profile to enable environment-specific configuration properties. But before going any further I\u2019m assuming that readers are aware of the concepts of creating and running a basic spring boot application.<\/p>\n
2. Spring Boot Profiles Tutorial<\/h2>\n
Here is a systematic guide for implementing this tutorial.<\/p>\n
2.1 Tools Used and Project Structure<\/h3>\n
We are using Eclipse, JDK 8, and Maven. In case you\u2019re confused about where you should create the corresponding files or folder, let us review the project structure of the spring boot application.<\/p>\n

3. Creating a Spring boot application<\/h2>\n
Below are the steps involved in developing the application.<\/p>\n
3.1 Maven Dependency<\/h3>\n
Here, we specify the dependency for the Spring boot. Maven will automatically resolve the other dependencies. The updated<\/strong> file will have the following code.<\/p>\n
pom.xml<\/em><\/span><\/p>\n
