This article mainly introduces "what are the benefits of using the Spring framework". In the daily operation, I believe that many people have doubts about the benefits of using the Spring framework. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts about "what are the benefits of using the Spring framework?" Next, please follow the editor to study!

1. What is the Spring framework? What are the main modules of the Spring framework?

Spring framework is a Java platform that provides comprehensive and extensive basic support for the development of Java applications. Spring helps developers solve fundamental problems in development, allowing developers to focus on application development. The Spring framework itself is carefully built according to the design pattern, which allows us to integrate the Spring framework with peace of mind in the development environment without having to worry about how Spring works in the background.

The Spring framework has integrated more than 20 modules so far. These modules are mainly divided into core containers, data access / integration, Web, AOP (aspect-oriented programming), tools, messages, and test modules as shown in the following figure.

2. What are the benefits of using the Spring framework?

Here are some of the main benefits of using the Spring framework:

The Dependency Injection (DI) method makes the dependency between the constructor and the JavaBean properties file clear at a glance. Compared with EJB containers, IoC containers tend to be more lightweight. This makes it advantageous for the IoC container to develop and distribute applications with limited memory and CPU resources.

Spring does not work behind closed doors. Spring leverages existing technologies such as the ORM framework, logging framework, J2EE, Quartz, and JDK Timer, and other view technologies.

Spring frameworks are organized in the form of modules. The modules to which they belong can be seen by the numbers of packages and classes, and developers only need to choose the modules they need.

It is easy to test an application developed in Spring because the test-related environment code is already included in the framework. More simply, using the POJO class in the form of JavaBean, you can easily write test data using dependency injection.

Spring's Web framework is also a well-designed Web MVC framework, which provides developers with a powerful choice in the choice of web frameworks in addition to mainstream frameworks such as Struts, overdesigned and unpopular web frameworks.

Spring provides a convenient transaction management interface for small local transaction processing (such as in a single DB environment) and complex common transaction processing (such as a complex DB environment using JTA).

At this point, the study on "what are the benefits of using the Spring framework" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
