All About Spring Framework in Java Development

Before the introduction of Enterprise Java Beans (EJB), Java developers had to build web applications using JavaBeans. Although JavaBeans aided in the creation of user interface (UI) components, they were unable to provide services like transaction management and security. These services were essential for the creation of strong and secure corporate applications.

The development of EJB was viewed as an answer to this challenge. EJB extends Java components, like web and enterprise components, and provides services that aid in the development of enterprise applications.

However, to develop enterprise applications using EJB the developer was required to execute a variety of activities which made the process difficult. That included creating Home and Remote interfaces and implementing lifecycle callback methods. This increased the complexity of supplying code for EJBs. As a result of this intricacy, developers began seeking a simpler approach to designing corporate apps.

The Spring framework (often referred to as Spring) has evolved as a solution to all of these difficulties. This framework develops enterprise applications utilizing many innovative approaches like 

  • Aspect-Oriented Programming (AOP)
  • Plain Old Java Object (POJO)
  • Dependency Injection (DI)

That reduces the difficulties inherent in building enterprise apps using EJB. Spring is a lightweight open source framework that allows Java EE 7 developers to create easy, dependable, and scalable corporate applications.

This framework primarily focuses on giving numerous methods to assist developers in managing business items. It makes web application development considerably easier than with traditional Java frameworks and Application Programming Interfaces (APIs). 

Features of Spring Framework

IoC Container

The core container employs the DI or IoC paradigm to give an object reference in a class at runtime. This pattern can be used instead of the service locator pattern. The IoC container includes assembler code that controls application object configuration management.

The Spring framework includes two packages, org.springframework.beans and org.springframework.context, which aid in delivering IoC container capabilities.

Data Access Framework

This allows a Java web application development company to store persistence data in databases using persistence APIs such as JDBC and Hibernate. It aids with the resolution of numerous development challenges, such as

  • how to communicate with a database connection
  • how to ensure that the connection has ended
  • how to handle errors
  • how to perform transaction management.

It also makes it simple for developers to implement code to access persistent data across the application. 

Spring MVC Framework

The Spring MVC framework allows developers to create web applications using the MVC architecture. All user requests are routed through the controller before being sent to multiple views, i.e. different JSP pages or Servlets. That makes it an essential part of the Java software development services.

The Spring MVC framework's form handling and form validation features are readily integrated with all common view technologies like Jasper Report, ISP, Velocity, and FreeMarker. 

Transaction Management

This helps an application handle transaction management without altering its code. The framework includes the Java Transaction API (JTA) for global transactions handled by an application server, as well as local transactions. JDBC Hibernate, Java Data Objects (JDO), or other data access APIs control this process.

It allows the developer to represent a broad variety of transactions using Spring's declarative and programmatic transaction management. Therefore, adding this feature to your Java application development services will be a huge plus. 

Spring Web Service

The Spring web service creates web service endpoints and definitions on the basis of Java classes. However, managing them in an application is complex. To address this issue, Spring Web Service offers tiered techniques that are maintained individually using Extensible Markup Language (XML) parsing. It is the process of reading and modifying XML.

Spring offers an effective mapping for sending an incoming XML message query to an object. That allows a Java application development company to simply spread an XML message (object) between two workstations. 

JDBC Abstraction Layer

This layer aids users in dealing with faults in a simple and effective manner. When developers use this abstraction layer in a Web application, it minimizes the JDBC programming code. This layer manages errors such as DriverNotFound.

All SQLExceptions are converted into the DataAccessException class. Because Spring's data access exception is not JDBC-specific, Data Access Objects (DAO) are not limited to JDBC. That’s why it is one of the most important features of the Spring Framework

Spring TestContext Framework

This framework provides unit and integration testing tools for Spring applications. Furthermore, the Spring TestContext framework includes integration testing functions such as context management and test fixture caching DI. It also consists of transactional test management with default rollback semantics. 

In Conclusion

If you want to make enterprise applications, then using the Spring framework is absolutely essential. But you need a tech partner that is expert in all the aspects of that framework. Only then you will be able to capitalize on its benefits.
