Why Spring framework is used in Java?
Spring is the most popular application development framework for enterprise Java. Spring framework targets to make J2EE development easier to use and promotes good programming practices by enabling a POJO-based programming model.
Which problem solution is addressed by spring dependency?

What are the benefits of Spring framework in software development?
The following is the list of a few great benefits of using the Spring Framework: Spring is a powerful framework, which address many common problems in Java EE.
Does using the Spring framework benefit Java developers?
Spring makes programming Java quicker, easier, and safer for everybody. Spring’s focus on speed, simplicity, and productivity has made it the world’s most popular Java framework.
What are the disadvantages of Spring framework?
Disadvantages of Spring Framework
- Complexity — The Spring framework has a lot of variables and complications.
- Parallel Mechanisms — One of the biggest advantages of Spring is that it gives developers a wide array of options, but this could also be a disadvantage because it causes confusion.
Why is Java spring so complicated?

- DO NOT: use Spring’s XML Bean definition support.
- DO: use Spring’s Java configuration.
- DO NOT: use Spring inside your domain classes.
- DO NOT: use entire classpath scanning.
- DO: use things like @Autowired in Spring-specific classes.
- DO: use Spring Test.
How does Spring achieve DI or IoC?
Spring implements DI by either an XML configuration file or annotations. Dependency injection is a pattern through which IoC is implemented and the act of connecting objects with other objects or injecting objects into objects is done by container rather than by the object themselves.

What are the features of the Spring Framework?
The Spring Framework has many other features, which are divided into twenty modules to solve many common problems. Here are some of the more popular modules: Aspect Oriented Programming (AOP) is another strong side of the Spring Framework. The key unit in object-oriented programming is the class, whereas, in AOP, the key unit is the aspect.
Which version of Java is used in springspring?
Spring 4 runs on Java 6, 7, and 8 and as a developer you can write your application code using any of Java 6, 7, 8. If you are using Java 8 you will be able to make use of lambda expressions to write cleaner more compact code anywhere there is a functional interface.
What is dependency injection in Spring Framework?
The Spring Framework is one of the most popular application development frameworks for Java. One of the best features in Spring is that it has the Dependency Injection (DI) or Inversion Of Control (IOC), which allows us to develop loosely coupled applications. And, loosely coupled applications can be easily unit-tested.
What is springspring boot autoconfiguration?
Spring Boot does all of those using AutoConfiguration and will take care of all the internal dependencies that your application needs — all you need to do is run your application. Spring Boot will auto-configure with the Dispatcher Servlet, if Spring jar is in the class path.
