What characterizes Java Development

Java stands out as a multi-platform, object-oriented programming language with a focus on networking. Over the past two decades, it has remained a preferred choice among developers for crafting web applications, evident from the multitude of Java applications in circulation today. Why the widespread popularity? Java’s popularity stems from its attributes of speed, security, and reliability, making it suitable for diverse applications ranging from mobile apps and enterprise software to big data and server-side technology. Its versatility and demand across various industries position Java developers as some of the highest-paid specialists in the IT sector.

Pre-requisite / Target Audience:

       Individuals aiming to learn the Spring Framework should possess fundamental understanding of Java and databases, including:

  • Core Java knowledge.
  • Familiarity with databases.
  • Basic comprehension of web application development.

Module 1: Spring Basics

This module is the core of the Spring Framework. It provides implementation for features like IoC (Inversion of Control) and Dependency Injection with a singleton design pattern. Inversion of Control (IoC) refers to a programming principle where the control of object creation and management is transferred to a framework rather than being handled manually in the code. Dependency Injection (DI) is a technique used to achieve IoC, allowing the injection of dependencies into objects, simplifying testing and enhancing code flexibility.

  • What is Spring Framework
  • Inversion of Control
  • Dependency Injection
  • Bean Factory
  • Developing First Spring Application

Module 2: Built-in Bean Factories

This module provides implementation for the factory design pattern through BeanFactory, and we will learnimplementation of ApplicationConext.

  • Application Context
  • Wiring Beans
  • Bean Lifecycle in Container
  • Spring Events

Module 3: Spring AOP

In this module we will learn by separating application business logic from system services, Spring Framework supports Aspect Oriented Programming and enables cohesive development.

  • Spring AOP Introductions
  • ProxyFactoryBean

Module 4: Spring Data Access

This module provides JDBC abstraction layer which eliminates the need of repetitive and unnecessaryexception handling code.

  • JDBC Abstraction Layer
  • Data Access Exceptions
  • DAO Support

Module 5: Spring O-R Mapping

ORM stands for Object Relational Mapping. This module ensures consistency and portability of code regardless of data access technologies, based on the object-oriented mapping concept. For example, Hibernate allows developers to map Java objects to relational database tables seamlessly, enabling them to write database-independent code while focusing on business logic rather than SQL intricacies.

  • What is O-R Mapping
  • O-R Mapping support in Spring
  • Hibernate Support / Mapping

Module 6: Spring Transaction Management

This module supports programmatic and declarative transaction management for classes that implement special interfaces and for all your POJOs. All the enterprise level transaction implementation concepts can be implemented in Spring by using this module.

  • Transaction Abstraction in Spring
  • Transaction Strategies
  • Programmatic Transaction
  • Declarative Transaction

Module 7: Spring Remoting and Enterprise Services

In this module we will learn how spring Remoting will be implemented by following RMI and various remotingtechnique.

  • Introduction to Spring Remoting
  • Java RMI in Spring
  • Accessing JNDI
  • Invoking EJB from Spring
  • Web Service in Spring using JAX-RPC Support
  • Messaging Support in Spring using JMS
  • Sending Mail with Spring Mail
  • Scheduling using Timer Support

Module8: Spring Web MVC Framework

This module contains Model-View-Controller (MVC)-based implementations for web applications, including UI tags and data validations.

  • Role of DispatcherServlet
  • Web MVC Architecture
  • Controller
  • Handler
  • View Resolving
  • Data Binding
  • File Upload Support

Module 9: Securing Spring Applications

In this module we will learn how spring security will be implemented by HTTP basic authentication and following concept.

  • Acegi Security System for Spring
  • Authentication
  • Access Control
  • Web Application Security
  • Method Invocation Security

Module 10: Spring Boot

This module explains how Spring Boot simplifies creating stand-alone, precompiled Spring-based applications.

  • Using Spring STS IDE
  • Using Spring Initializer Website
  • Hello World example using spring boot
  • Java-Based Applications

Relational Persistence UsingHibernate

Module 1: Introduction to Hibernate

This module explains how the Hibernate framework simplifies Java application development for database interaction. Hibernate is an open-source, lightweight ORM (Object Relational Mapping) tool. Compared to other ORM tools like EclipseLink or JPA, Hibernate stands out for its robust caching mechanisms, support for lazy initialization, and its flexibility in handling complex database relationships. This makes it a preferred choice for developers building scalable and efficient applications.
