The spring framework is a collection of open-source tools for building modern, maintainable, and flexible web applications. With the spring framework, you can create an application that uses less memory, has less disk activity, deploys to the cloud more quickly, and uses less time from a developer’s idle time. The goal of spring is to help developers create lightweight, maintainable and flexible web applications that are fast and responsive in all aspects of their work. The Spring Framework provides a set of tools for easily building such applications.
The Basic feature of the java spring framework targets to make J2EE development easier to use and promotes good programming practices by enabling a POJO-based programming model. It helps the developer in writing less code with more support and allows them.
Benefits of Using the Spring Framework
Some benefits of using the Spring framework for developing web services.
- The aim of using a Spring framework is to do the job of configuring and managing the web application.
- There are no third-party libraries such as Log4j, JDBC Data Source, or others that are required.
- Spring MVC is lightweight, which means if you ever want to replace it, it would be easy.
- It uses Convention Over Configuration. This means that you have less configuration to deal with and your project can be set up in very little time.
- It eases the development of enterprise Java applications.
- It is compatible with a wide range of J2EE and orient framework capabilities.
- It is open source and hence available for modification to suit one’s needs.
- Spring is a great choice for Java developers, and it provides many options to implement your component. Developers have many choices of tools and application servers.
- Provides top-quality unit testing.
- Promotes rapid development.
Dependency Injection (DI)
Dependency injection is a mechanism used to manage the lifecycle of an application. As an application is developed, it contains classes and methods that have dependencies on other classes and methods. The goal of dependency injection is to isolate such items from other application logic until they are needed by the implementing class or method. Once an application is created, its implementation is often exposed to other classes and methods through the use of abstract classes or interfaces. Since an interface cannot itself contain implementation, this technique is often used to pass objects from one class or method to another as part of a development process.
When creating a complex Java program, application classes should be as independent as feasible from other Java classes so that they may be reused and tested independently from several other classes during unit testing. Dependency Injection aids in the bonding of these classes while maintaining their independence.
(AOP) Aspect-Oriented Programming
AOP of spring framework is a method for writing computer programs that makes it easier to understand how the programs work and to improve them. As the name suggests, aspect-oriented programming requires that the programmer takes into account aspects of their program when developing or changing it. This could include how the program will work with other programs or the hardware it is running on.
The best-known AOP framework is the Agile software development method, which helps to develop applications using small unit tests for functionality and test-driven development for application design.
