Getting Started With SpringBoot Application


Spring Boot is associated open-source Java-based framework wont to produce a small Service. It’s developed by the crucial Team and is employed to create complete and production-ready spring applications. This chapter can offer you an introduction to Spring Boot and familiarizes you with its basic ideas.

What is Spring Boot?
Spring Boot provides a decent platform for Java developers to develop a complete and production-grade spring application that you simply will just run. You’ll start with minimum configurations while not the requirement for a whole Spring configuration setup.

Spring is that the most popular and innovative community for Java developers. They need to modify the method how to build enterprise applications and how to manage them. Spring Boot is their latest innovation to stay up to now with the dynamic technology desires. The first motivation behind developing Spring Boot is to simplify the method for configuring and deploying the spring applications.

Why do we need Spring Boot?

  • Spring Boot is a next-generation attempt to easy spring setup.
  • Spring Boot’s main benefit is configuring the resources based on what it finds in the classpath.
  • If your maven pom includes JPA dependencies and MYSQL driver, then Spring Boot can be created a persistence unit supported by MySQL. If you’ve added an internet dependency, then you may get Spring MVC organized with defaults.
  • When we point out defaults, Spring Boot has its own opinions. If you’re not specifying the main points, it’ll use its own default configurations. If you would like persistence, however, don’t specify anything in your pom file, then Spring Boot configures Hibernate as a JPA supplier with an HSQLDB database.

How does it work?

Some is also asking themselves however will Spring Boot has auto configurations and what will very that basically that actually mean? It really comes right down to three easy Spring Boot annotations that offer this feature:


Between each one of these annotations, Spring Boot is able to provide default project dependencies as well as allow for defaults to be overwritten.

@SpringBootApplication is used within the entry purpose of the application add the category it resides in has to get to the application main technique. The annotation is required and can offer every of the opposite two annotations to your Spring Boot application since the @SpringBootApplication includes each inside.

The @EnableAutoConfiguration does just that it provides each of the representing classes with the Automatic Configuration capability.

Lastly, the @ComponentScan will at initialization scan all the beans and package declarations.

Spring Starter Dependencies
Not solely will Spring Boot include annotations however it conjointly uses Spring Starter Dependencies to make sure that your application starts with the proper dependencies therefore so you can and then you’ll hit the bottom running so to talk.

Many times, as an application grows larger it is laborious to properly set up project dependencies, the Spring Boot Starter plugins can help facilitate dependency management. an example of a spring starter dependency is that the Spring Boot Starter internet dependency.

That will be used so your application can have Rest Endpoints written into your application. Overall, they assist contour the event of those applications so a team can begin from an additional advanced purpose therefore fewer holes are going to be conferred particularly with larger applications.

Spring Boot Features

Web Development
It is a well-suited Spring module for internet application development. we are able to simply produce a self-contained HTTP server using embedded tomcat, Jetty, or Undertow. we are able to use the spring-boot-starter-web module to start out and running applications quickly.

It is a class that provides a convenient way to bootstrap a Spring application which can be started from the main method. You can call start your application just by calling a static run() method.

Application Events and Listeners
Spring Boot uses events to handle a variety of tasks. It allows us to create factories file that is used to add listeners. we can refer to it by using the ApplicationListener key.

Admin Support
Spring Boot provides the facility to modify admin-related features for the appliance. It’s wont to access and manage applications remotely. We will modify it by simply exploiting the spring application admin-enabled property.

Externalized Configuration
Spring Boot permits us to externalize our configuration so we will work with a similar application in several environments. The application uses YAML files to externalize configuration.

Properties Files
Spring Boot provides a rich set of Application Properties. So, we are able to use that within the properties file of our project. The properties file is used to line properties like server-port = 8082 and lots of others. It helps to arrange application properties.

YAML Support
It provides a convenient way for specifying hierarchical configuration. It is a superset of JSON. The SpringApplication class automatically supports YAML. It is a successful alternative to properties.

Type-safe Configuration
A strong type-safe configuration is provided to manipulate and validate the configuration of the application. Application configuration is usually an important task that ought to be type-safe. We are able to conjointly use annotation provided by this library.

Spring Boot uses Common logging for all internal logging. Logging dependencies are managed by default. We must always not modification logging dependencies if there’s no needed customization is required.

Spring Boot applications are spring bases net applications. So, it’s secure by default with basic authentication on all HTTP endpoints. A rich set of Endpoints are obtainable for developing a secure Spring Boot application.

Spring Boot Benefits

  • Application monitoring
  • Auto-Configurable
  • Caching providers
  • Application configurations flexibility

Responsibilities of SpringBoot

Designs, codes or configures, tests, debugs, deploys, documents and maintains web service applications using a variety of software development toolkits, testing/verification applications, and other tools while adhering to specific development best practices and quality standards.

Advantages of Spring Boot

  • It creates stand-alone Spring applications that can be started using Java -jar.
  • It tests web applications easily with the help of different Embedded HTTP servers such as Tomcat, Jetty, etc. We don’t need to deploy WAR files.
  • It provides opinionated ‘starter’ POMs to simplify our Maven configuration.
  • It provides production-ready features such as metrics, health checks, and externalized configuration.
  • There is no requirement for XML configuration.
  • It offers a CLI tool for developing and testing the Spring Boot application.
  • It offers a number of plug-ins.
  • It also minimizes writing multiple boilerplate codes (the code that has to be included in many places with little or no alteration), XML configuration, and annotations.
  • It increases productivity and reduces development time.

The primary roles of Spring-Boot:

  • To provide a bunch of non-functional features/solutions that are very much common to large-scale projects (e.g. embedded servers, security, metrics, health checks, externalized configuration).
  • To provide a radically faster and widely accessible getting started development experience for all Spring development. Since the spring community has evolved so big, it is time to re-invent the way how spring applications are deployed in a much quicker turnaround time.
  • To be get started so quickly using the default values which are supported out of the box in the Spring Boot configurations.

Scope of SpringBoot

Scopes a single bean definition to any range of object instances. Scopes a single bean definition to the lifecycle of one HTTP request; that’s every and each HTTP request can have its own instance of a bean created off the rear of a single bean definition.

Location of Docker images in all Operating Systems (Linux, Windows, Redhat, Mac OS X)

Location of Dockers images in all Operating Systems
The location of the images vary depending on the driver Docker is using for storage. Actually, Docker images are stored in two files as shown by following command.
# docker info
aufs – Most linux version
/var/lib/docker/aufs/diff/<id> has the file contents of the images.
/var/lib/docker/repositories-aufs is a JSON file containing local image information. This can be viewed with the command docker images.
devicemapper (Redhat)
/var/lib/docker/devicemapper/devicemapper/data – stores the images
/var/lib/docker/devicemapper/devicemapper/metadata – the metadata
Mac OS X
~/VirtualBox VMs/boot2docker-vm
Mac OS X using boot2docker 
File Name – disk.vmdk
%USERPROFILE%/VirtualBox VMs/boot2docker-vm
You can manually set the storage driver with the -s or –storage-driver= option to the Docker daemon.
/var/lib/docker/{driver-name} will contain the driver specific storage for contents of the images.
/var/lib/docker/graph/<id> now only contains metadata about the image, in the json and layersize files.
