Spring Boot – Profile based properties example.

A profile is a set of settings that can be configured to override settings from Each profile is contained in a file named where profilename is the name of the profile. Now, a profile could configure anything you want, however for most projects it is proposed to have the following profiles:

dev for your local development settings

staging for your staging server settings

prod for your production settings

test for running your tests

Whether you have all above environment in your application or not, you must have a dev, a prod and a test profile. The configuration for these environments needs to be different for obvious reasons. Now lets see how spring boot manages profile based properties in any application. All you need is create different properties for different profiles or environments as shown below:

Spring boot will bind all the properties to below class:

package com.java2novice.springboot.util;

import java.util.List;

import javax.validation.constraints.Max;
import javax.validation.constraints.Min;

import org.hibernate.validator.constraints.NotEmpty;
import org.springframework.context.annotation.Configuration;

public class CmdbProperties {

	private String resourceUrl;

	private List<Integer> resourcePort;

	private Integer resourceCount;

	public String toString() {

		return "resourceUrl: "+ this.resourceUrl+"\n"
				+ "resourcePort: "+this.resourcePort+"\n"
				+ "resourceCount: "+this.resourceCount+"\n";

	public String getResourceUrl() {
		return resourceUrl;
	public void setResourceUrl(String resourceUrl) {
		this.resourceUrl = resourceUrl;
	public List<Integer> getResourcePort() {
		return resourcePort;
	public void setResourcePort(List<Integer> resourcePort) {
		this.resourcePort = resourcePort;

	public Integer getResourceCount() {
		return resourceCount;

	public void setResourceCount(Integer resourceCount) {
		this.resourceCount = resourceCount;

And here is the Spring boot application class:

package com.java2novice.springboot;

import javax.annotation.PostConstruct;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import com.java2novice.springboot.util.CmdbProperties;

public class SpringBootWebApplication {

	private static Logger logger = LoggerFactory.getLogger(SpringBootWebApplication.class);

	private CmdbProperties cmdbProperties;

	public static void main(String[] args) throws Exception {, args);

	public void init() {;

Now package the application and run: You can pass the profile values as part of command line arguments by using "". We will pass prod profile as an input:

java -jar target/spring-boot-tutorials-0.0.1-SNAPSHOT.jar

resourcePort: [80, 443]
resourceCount: 2

java -jar target/spring-boot-tutorials-0.0.1-SNAPSHOT.jar
resourcePort: [8080]
resourceCount: 2

Stream and types of Streams
A Stream is an abstraction that either produces or consumes information. There are two types of Streams and they are:

Byte Streams: Provide a convenient means for handling input and output of bytes. Byte Streams classes are defined by using two abstract classes, namely InputStream and OutputStream.

Character Streams: Provide a convenient means for handling input & output of characters. Character Streams classes are defined by using two abstract classes, namely Reader and Writer.
