How to build spring boot application for Production , UAT Testing and Dev Environment using Eclipse.

In this blog I will show you that how we can build Spring Boot Application for different Environments like Production , UAT Testing and Dev. Here i am creating a Spring Boot Application and also you can download this application at the end of this post.

create a Controller class
------------------------------ AppController.class -----------------------------

@RestController
@RequestMapping("/api")
public class AppController {

@GetMapping("/status")
public String runningStatus() {
String deployName = VariableConfig.CURRENT_ENVIRONMENT;
System.out.println("/api/=> runningStatus()..."+VariableConfig.CURRENT_ENVIRONMENT);
return "<h3 style="color: red;">"+deployName+"</h3><h2 style="color: green;">Application is Running....</h2>";
}

}

create a config class for set currrent Environment variable

--------------------------------VariableConfig.class---------------------

@Component
public class VariableConfig {

public VariableConfig() {

}

public static String CURRENT_ENVIRONMENT;

@Value("${environment.current}")
public void setCurrentEnvironment(String currentEnvironment) {
CURRENT_ENVIRONMENT = currentEnvironment;
}
}

create four properties files for local, prod and stage Environments.

application.properties
application-local.properties
application-prod.properties
application-stage.properties

----------------application.properties-------------------

spring.profiles.active=@activatedProperties@

----------------application-local.properties--------------------

profile.environment.current=local
server.servlet.context-path=/profile
server.port=8080
environment.current=Local Environment

----------------application-prod.properties----------------------

profile.environment.current=prod
server.servlet.context-path=/profile
server.port=9090
environment.current=Prod Environment

----------------application-stage.properties---------------------

profile.environment.current=stage
server.servlet.context-path=/profile
server.port=2020
environment.current=Stage Environment

----------------------pom.xml--------------------------
