We can create loosely coupled applications that can be easily tested and maintained using these design patterns. The most fundamental aspect of Spring and Spring Boot is Dependency Injection (DI) or Inversion of Control (IoC), the cornerstone of every Spring Module. To create the package in Eclipse IDE: Right-click src directory → New → Package → Name your Package. The first step is to create a java project in your compiler (we are using Eclipse here).Īfter creating a Java Project, Create a Package. Let’s have a look at how to create your first message with Spring. This way, it is easy to test, reuse and maintain code agilely. Spring framework addresses the current needs of enterprise application development by introducing a paradigm for building applications with POJOs (Plain Old Java Objects) so that business objects are not tied to any specific framework or runtime environment. Spring focuses on several areas of application development, providing a wide range of features that help simplify Java EE development and help developers be more productive. Spring framework is one of the most versatile and powerful frameworks in Java. The Spring framework provides many APIs to boost developer productivity, including transaction management and integration, data access and security, server-side technology abstraction, etc. It simplifies enterprise Java development by providing a comprehensive programming and configuration model for web and non-web application parts. The Spring Boot features and Spring framework offers a robust, lightweight infrastructure for Java applications. It provides declarative support for caching, validation, transactions and formatting.Spring is a widely-adopted open-source framework for building enterprise applications. It provides powerful abstraction to JavaEE specifications such as JMS, JDBC, JPA and JTA. The Dependency Injection feature of Spring Framework and it support to various frameworks makes the easy development of JavaEE application. The Spring Framework doesn't force the programmer to inherit any class or implement any interface. Spring framework is lightweight because of its POJO implementation. The EJB or Struts application require server to run the application but Spring framework doesn't require server. The Dependency Injection makes easier to test the application. The Spring applications are loosely coupled because of dependency injection. You need to write the code of executing query only. Let's take the example of JdbcTemplate, you don't need to write the code for exception handling, creating connection, creating statement, committing transaction, closing connection etc. It hides the basic steps of these technologies. So there is no need to write too much code. Spring framework provides templates for JDBC, Hibernate, JPA etc. They are as follows: 1) Predefined Templates There are many advantages of Spring Framework. makes the code loosely coupled so easy to maintain.We provide metadata to the IOC container either by XML file or annotation. In Spring framework, IOC container is responsible to inject the dependency. In such case, there is no need to modify the code if our logic is moved to new environment. Thus, IOC makes the code loosely coupled. Let's understand this with the following code: They make the code easier to test and maintain. These are the design patterns that are used to remove dependency from the programming code. Inversion Of Control (IOC) and Dependency Injection Let's understand the IOC and Dependency Injection first. We will learn these modules in next page. The Spring framework comprises several modules such as IOC, AOP, DAO, Context, ORM, WEB MVC etc. The framework, in broader sense, can be defined as a structure where we find solution of the various technical problems. It can be thought of as a framework of frameworks because it provides support to various frameworks such as Struts, Hibernate, Tapestry, EJB, JSF, etc. It is helpful for beginners and experienced persons. Spring framework makes the easy development of JavaEE application. This spring tutorial provides in-depth concepts of Spring Framework with simplified examples.
