Skills for Java EE Developer

In this post, we would like to suggest the skills required to work on Java EE development.

Skills for Java EE development

Once you are familiar with Core Java development then learn the below skills to work on Java EE development:


Java EE Technologies

JSP and Servlets

JSP and Servlets are used to develop web applications.

JPA

The Java Persistence API (JPA) is the Java standard for mapping Java objects to a relational database. Mapping Java objects to database tables and vice versa is called Object-relational mapping (ORM).

JPA implementation is provided as a reference implementation by the vendors developing O/R Mapper such as Hibernate, EclipseLink, and Apache OpenJPA.

JAX-RS

JAX-RS is Java API for RESTful Web Services (JAX-RS) is a Java programming language API spec that provides support in creating web services according to the Representational State Transfer (REST) architectural pattern.
There are two main implementations of the JAX-RS API:
1. Jersey Framework
2. RESTEasy

JAX-WS

Java API for XML Web Services (JAX-WS) is a standardized API for creating and consuming SOAP (Simple Object Access Protocol) web services.

Hibernate Framework

As a Java EE programmer, you must learn the Hibernate framework to develop the DAO layer.

Hibernate is a java based ORM tool that provides a framework for mapping application domain objects to the relational database tables and vice versa.

Hibernate is probably the most popular JPA implementation and one of the most popular Java frameworks in general. Hibernate acts as an additional layer on top of JDBC and enables you to implement a database-independent persistence layer. It provides an object-relational mapping implementation that maps your database records to Java objects and generates the required SQL statements to replicate all operations to the database.

Spring Framework

Spring framework makes Java EE development easier. Spring framework is a must-learn skill for Java EE developers.

The Spring Framework is a Java platform that provides comprehensive infrastructure support for developing Java applications. Spring handles the infrastructure so application developers can focus on your application.

Spring Boot

Spring Boot is basically an extension of the Spring framework which eliminated the boilerplate configurations required for setting up a Spring application.

Spring Boot is an opinionated framework that helps developers build Spring-based applications quickly and easily. The main goal of Spring Boot is to quickly create Spring-based applications without requiring developers to write the same boilerplate configuration again and again.

Spring boot is one of the essential skill for Java EE developers right now.

Microservices

Spring Boot and Spring Cloud is a great combination to develop a microservices in Java.

Spring Boot is the most popular and widely used Java framework for building MicroServices. These days many organizations prefer to deploy their applications in a Cloud environment instead of taking all the headache of maintaining a datacenter themselves. But we need to take good care of the various aspects to make our applications Cloud Native. There comes the beauty of Spring Cloud.

Spring Cloud is essentially an implementation of various design patterns to be followed while building Cloud Native applications. Instead of reinventing the wheel, we can simply take advantage of various Spring Cloud modules and focus on our main business problem than worrying about infrastructural concerns.
