Language Fundamentals
Syntaxes
Standalone apps
Technologies: JDBC + Servlets + JSP
Database communication using JDBC
Servlets for web application development
JSP ==Presentation logic
= Web applications
Java Frameworks: Hibernate + spring -- Spring Boot
Core Java: To develop Standalone applications
JDBC: To develop persistence logic
Servlets: To develop web applications
JSP: To develop Presentation logic
What is Framework?
= Framework is a semi developed / readymade software
= Frameworks will provide some common logics required for several projects development.
= Frameworks provides re-usable components ==classes & interfaces
= Frameworks will reduce burden on the developers
= IN Java community we are having 2 types of frameworks
1 ORM frameworks Ex: Hibernate - Object Relational Mapping
2 Web Frameworks Ex: Struts - 2001
Note: Spring is called as Application development Framework ==interface21
1st spring version came into market 2003/2004
Current version of Spring is 6.x
Spring is not single framework
Spring Framework is collection of frameworks ==Modules
Spring 1.x --- 7 Modules
Spring 2.x --- 6 Modules
Spring 3.x ---- 20+ Modules
Spring Framework is versatile framework
Spring is loosely coupled framework
What is Spring?
Spring is a java based application development framework
By using spring we can develop end to end application
Spring is developed by using JSE & JEE
Spring framework developed by Rod Johnson
First version of spring came into market in 2004 ==Spring 1.x v
The current version of Spring is 6.x ==2024
Spring is developed in modular fashion
Spring Modules are loosely coupled
Spring is versatile framework ==it can integrate with any other framework
Spring Framework Modules
1 Spring Core
2 Spring Context
3 Spring DAO
4 Spring ORM
5 Spring AOP
6 Spring Web MVC
7 Spring REST
8 Spring Data JPA
9 Spring Cloud
10 Spring Security
11 Spring Social
12 Spring Batch
Spring Core
Base module of spring framework
Core Module providing fundamental concepts of Spring those are
IOC : Inversion Of Control
DI : Dependency Injection
IOC & DI are used to develop classes with loosely coupling
IOC will take care of java objects life cycle ==Spring Beans
Spring Context
TO manage configurations in Spring application we will use Context Module
It provides configuration support required for managing classes
Spring AOP
AOP : Aspect Oriented Programming
-- AOP is used to separate cross cutting logics in the application
Cross Cutting / Secondary / Helper Logics
Ex : Security, transaction, Logging, Auditing & exception handling etc...
Spring DAO / Spring JDBC
Spring JDBC is extension for Java JDBC
To simplify persistence logic development we can use Spring JDBC
JDBC Logic
-----------
1. load driver
2. get connection
3. Create statement
4. Execute query
5. process result
6. Close connection
spring jdbc
-----------
1. Execute query
2. process result
= Spring JDBC provided predefined classes to perform DB operations
Ex: JdbcTemplate, NamedJdbcTemplate etc...
Spring ORM
= SPring ORM module is extension for existing ORM frameworks
ORM - Object relational mappping
= To suppport ORM integrations we have Spring ORM module
Spring ORM = Spring + ORM Framework Ex: Hibernate
Hibernate
---------
1. Create Config obj
2. create session factory
3. create session
4. begin tx
5. execute methods
6. commit tx
7. close session
8. close sf
spring orm
