Your First Touch On Spring Boot
As the programming beginner or software worker from the previous journals we have discussed programming languages and how do we start the programming career at this stage. So, It is essential to have some idea on framework so today I am going to make you aware of Java Spring boot framework.
Whenever you are going to talk about open source software and the fundamentals, Java Spring Framework must be considered as one of the most popular open source enterprise-level frameworks.
Java Spring Framework or we usually call it as spring framework is some kind of popular and open source software framework all the production of this application may run on Java Virtual Machine as normal Java programs do.
Spring Framework offers much more features and advantages for its uses, for example it was a dependency injection feature. That is something that lets the object define their own dependencies that spring container will inject into them later.
you can have a chance to make loosely coupled components that are most probably ideal for microservices for the distributed network applications. and also has its own built-in support for several services for the application that needs to do data binding, type conversion, validation, exception handling, resource and event management, initialization and so on.
Usually it integrates several Java Technologies( AMQP, RMI, Java Web Services) . When I take a set at the integers that can be using spring I can summaries it as it will be available at home making that loosely coupled, cross platform applications for running any environment.
When we take Java Spring boot specifically it is a tool that makes the API with application and microservices by using spring framework on much powerful way.
When you are trying to do something with spring rather than spring boot you have to engage on so many configurations and so many kinds of initial clarifications for using spring. Even though it is not that bad this spring boot Framework can make it easy to create a stand alone application that you will be able to just run. I mean by using a very small kind of configuration you can easily run spring boot programs. Spring boot has so many Added qualities than normal spring framework and it is almost more flexible than spring framework.
When we are talking about spring boot it is better to use unique configurations. Without that also, you are still able to use spring framework's very popular annotation system that lets you easily inject extra dependencies (not covered by Spring Starters) into your application. And, you still get access to all Spring Framework features, including easy event handling, validation, data binding, type conversion, and built-in security and testing capabilities. Bottom line, if your project’s scope is covered by even just one Spring Starter, Spring Boot can significantly streamline development.[01]
It is said that spring boots have their own opinions. That is because of the number of reasonable defaults that spring boot makes available for you. But also so the spring boot can be used in your own way or any customized way you want. Sometimes most of the experienced programmers are asking home building their software by using their own customized way then that much opinionated framework. for example, When you are working with ‘ Maven ‘ you are able to make changes in your files by changing the spring boot default values easily.
Spring Framework faster and easier through three core capabilities:
Autoconfiguration
Autoconfiguration means that applications are initialized with pre-set dependencies that you don't have to configure manually. Java Spring boot comes with auto configuration error so it can configure the spring framework and uses that you are added according to the setting you have settled. By using this advanced feature. You can have fast and accurate development even with the changed environment that you have created.
An opinionated approach to configuration
It is used for adding and configuring starter dependencies based on the needs of the ideas that you are wishing to enter on your project. I have mentioned above that spring boot is some kind of easily configured or ‘ just running’ approach. so that springwoods automatically determines which packages to install and which default values to use according to your entries and needs of your project respectively. also you can get a chance to manually make those decisions at all. you can define those needs of your project during the initialization process of the project. They are calling spring starters that cover those specific use cases.(sometimes you are able to to run spring boot initializer by filling out justice simple feeling in a sample web form without any coding)
When I am taking the example for the above mentioned thing, spring web starter dependency allows you to build spring based web applications with that much of minimal configurations. Here the most wanted dependencies such as Apache Tomcat will automatically set it on your project. and also the authentication mechanism will be added automatically for that particular project.
Spring Boot initially gives us over 50 of spring starters. Also, there are so many third party spring starters available for you.
The ability to create standalone applications
As I have mentioned at the beginning of spring boot, it helps you to develop a web application without relying on external web servers. That's because it is embedding a web server most probably as Tomcat (sometimes ' Netty ') at the very beginning of the initialization process.so this added advantage makes it possible to run your program by entering simply run command without having multiple dependencies and so on. Also this spring boot makes you available to make applications without using this initially embedding web servers 50 Tom Cat as well.
Installation process of spring boot
For this we can just install Apache Maven latest version under your JDK version that you already have installed with the previous works (Journals)
Use link :-Maven.apache
Starters
I have this discussed with you about the starters of the spring boot. actually, starters are doing valuable part of the configuration that you have to do.
we can say that starters reduce the amount of manual dependency configuration that you have to do. starters are the set of dependencies Specific for your program. also the starters used naming conversions.
- spring-boot-starter-RK,
- RK is the type of build type.
- More from official spring reference :-
https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#using.build-systems.starters
Auto-configuration
Also the spring boot can configure its own by using, @EnableAutoConfiguration if you not specify any and (--debug option and an auto-configuration report will be generated) Auto-configuration is based on the JARS in class path and how you’ve defined your beans.
The Spring Boot über jar
This is not that moderately new concept that have been introduced to the the Developers that they will be able to run their application without out bothering so many about the other things. that you can simply make an executable JAR. and run it within the program.
$ java ‑jar PATH_TO_EXECUTABLE_JAR/executableJar.jar
So up to now I have make you aware about the main concept and the initial configuration about the speed boot on spring framework respectively so let’s get hand together to me and application by using spring boot As the final step.
*Also the example code is uploaded for the repository as well.
Shorted Terms :-
- RMI (Remote Method Invocation)
- AMQP (Advanced Message Queuing Protocol)
