What are Profiles in Spring Boot Profiles can be seen as different environments in spring boot application. Suppose you are working on an application where you have different staging environments like Dev, QA, UAT, Production etc. So you will have different configurations for each environment, for this kind of applications what you need is having different values that can be switched depending upon some flags. In early days, people used to write configurations for all environments and comment the unused environments. But with Spring Boot we can do this without commenting any code by use of Profiles . Suppose we have database name configurations for our application as follows Dev     - ekiras_dev QA    - ekiras_qa UAT  - ekiras_uat Prod  - ekiras Now, we can use profiling in this case. How we will do it ? lets see Creating Profiles in Spring Boot  We will create different files for different environments and call then as profile in rest of the blog...
