SkillPractical has Spring learning path that helps the user to learn the Java from scratch. If user have any questions on Java Spring while attempting tests, he can post a question in SkillPractical community. They will get an answer from our expert consultants.

Spring is widely used for creating scalable applications. For web applications Spring provides
SpringMVC whichisa widelyusedmoduleof springthatisusedto create scalable webapplications.
But the main disadvantage of springprojects is that configurationis really time-consuming and can
be a bit overwhelming for the new developers. Making the application production-ready takes
some time if you are new to the spring.
Here in thisproject,we will discusshowtocreate abasic RESTful webservice which displays the list
of studentdetailsanddetailsof individual studentdependinguponthe idprovidedthroughthe REST
call i.e.., depending upon the input provided through the REST call.
Prerequisites:
 Basic understandingof howtocreate a Mavenprojectin IntelliJIDE.
 Basic understandingof RESTful webservices.
 Basic understandingof HTTPMethodsi.e.,GET, PUT, POST,DELETE etc..
Advantages of RESTful Web services:
1. The separation between the client and the server: The REST protocol totally separates the
userinterface fromthe serverandthe data storage.Thishas some advantageswhenmaking
developments. For example, it improves the portability of the interface to other types of
platforms,itincreasesthe scalabilityof the projectsandallowsthe different components of
the developments to be evolved independently.
2. Visibility, reliability, and scalability: The separation between client and server has one
evident advantage, and that is that each development team can scale the product without
too much problem. They can migrate to other servers or make all kinds of changes in the
database, provided the data from each request is sent correctly. The separation makes it
easier to have the front and the back on different servers, and this makes the apps more
flexible to work with.
3. The REST API is always independent of the type of platform or languages: The REST API
always adapts to the type of syntax or platforms being used, which gives considerable
freedomwhenchangingortestingnew environmentswithin the development. With a REST
API, you can have PHP, Java, Python or Node.js servers. The only thing is that it is
indispensable that the responses to the requests should always take place in the language
used for the information exchange, normally XML or JSON.
The stepsthat we coveredinthisprojectare:
1. Create a mavenprojectandass dependencies
2. Create a minimal setof classesandlaunchthe application
3. Add at leastone controllerwithrespectiveServices,EntityandDAO(DataAccessObject)
