Q1) What is Spring Framework? What are some of the important features and advantages of Spring Framework?
Spring is one of the most widely used Java EE framework.
I like spring because it provides a lot of features and capabilities.
it has different modules for specific tasks such as Spring MVC , Spring JDBC , Spring Web, Spring AOP, Spring Security and Spring BOOT etc.
it can be used to achieve loose coupling between different components by implementing dependency injection and we can perform cross cutting tasks.
-------------------------------------------------------------------------
Lightweight and very highly used framework
Dependency Injection or Inversion of Control to write components that are independent of each other,
spring container takes care of wiring them together to achieve our work.
Spring IoC container manages Spring Bean life cycle and project specific configurations such as JNDI lookup.
Spring MVC framework can be used to create web applications as well as restful web services capable of returning XML as well as JSON response.
Support for transaction management, JDBC operations, File uploading, Exception Handling etc with very little configurations, either by using annotations or by spring bean configuration file.
Some of the advantages of using Spring Framework are:
-----------------------------------------------------
Reducing direct dependencies between different components of the application,
usually Spring IoC container is responsible for initializing resources or beans and inject them as dependencies.
Writing unit test cases are easy in Spring framework because our business logic doesn’t have direct dependencies with actual resource implementation classes. We can easily write a test configuration and inject our mock beans for testing purposes.
Reduces the amount of boiler-plate code, such as initializing objects, open/close resources.
I like JdbcTemplate class a lot because it helps us in removing all the boiler-plate code that comes with JDBC programming.
Spring framework is divided into several modules, it helps us in keeping our application lightweight. For example, if we don’t need Spring transaction management features, we don’t need to add that dependency in our project.
Spring framework support most of the Java EE features and even much more. It’s always on top of the new technologies, for example there is a Spring project for Android to help us write better code for native android applications. This makes spring framework a complete package and we don’t need to look after different framework for different requirements.
